Definitions
- the present invention relates to an unproved method of effecting enhanced penetration of wood preservatives into wood and, more specifically, it relates to such a method which employs a buffered compound which facilitates enhanced penetration of wood preservatives into the wood.
- the wood is treated with water or solvents that carry preservatives.
- the pressure or vacuum methods cause the wood to pick up large amounts of these carriers and, as a result, require kiln drying or oven drying or long-term air drying to allow the wood to be useful.
- Such drying of pressure or vacuum-treated wood using water as a carrier can cause structural defects such as warping, cracking and checking.
- United States Patent No. 7,655,281 discloses a method of protecting wood through enhanced penetration of wood preservatives by providing a solution which, includes at least one amine oxide, at least one organic wood preservative, and a buffering agent.
- the buffering agent is selected from the group consisting of borates, boric acids, and combinations thereof.
- the method of the present invention permits enhanced penetration of wood preservatives through the use of solutions having a buffered pH above the pH of the wood achieved through the use of a combination of an amine oxide and a non-borate buffering agent.
- a solution is created with at least one amine oxide along with the wood preservative which is to be applied to the wood and a buffering agent.
- This solution has a pH of about 5 to 12.4 and preferably about 7 to 10 and most preferably about 7 to 8.5. It is applied to the surface of the wood. With or without intervening storage, activation results in the amine oxide and the buffering agent in the solution combining to enhance penetration into the wood of one or more wood preservatives. It is preferred that the application be at a solution temperature of about 30°C to 75°C and that the activation be at a higher temperature in a high relative humidity environment. The wood may also be heated before and/or after application of the solution to enhance penetration.
- the depth of penetration of each may be to a different level, but, in general, would be enhanced as compared with introduction of the wood preservatives without the combination of the buffering agent and amine oxide present,
- the Figure is a schematic illustration of a cross-section of a portion of a wood sample
- buffering agent and “non-borate based buffering agent” mean buffers which have a combination of a weak acid, with a strong base or a strong base with a weak acid, or a weak acid and weak base and contains no substantial amount of borates, boric acid, or borax and shall expressly include, but not be limited to, buffers selected from the group consisting of citric acid-'monopotassium citrate, amtmonium/ammonia, potassium phosphate monobasic/potassium phosphate dibasic, monopotassium citrate/dipotassium citrate, monosodium ascorbate/disodium ascorhate, sodium bicarbonate/sodium carbonate, acetoxirae/ water, mononegative lysine/dinegative lysine, sodium phosphate monobasic/sodium phosphate dibasic, sodium phosphate dibasic/sodium phosphate tribasic, and potassium bicarbon
- wood- means wood, wood-based materials, wood fiber materials, forest products, timber, lumber, engineered wood, millwork, joinery, wood laminates, laminated veneer lumber, plywood, laminated strand lumber, wood fiber composites, medium density fiberboard, particle board, hard board, oriented strand board, wood fiber resin composites, wood strand resin composites, wood particle resin composites and other wood and wood fiber-based materials and fabricated and semi-fabricated items made therefrom,
- wood preservatives means organic compounds, halo- organic compounds, metalo-organic compounds, metallic salts and organo-salts, organophosphates and non-organoboron compounds having fungicidal, inseeticidal, water- resistant, termite-resisting, decay-resisting, stain-resisting or other wood-protective properties.
- amine oxide or "amine oxide compound” refers to those compounds which are formed as reaction products in the reaction of tertiary amines and hydrogen peroxides and are represented by the general formula: where R 1, R 2, and R 3 are independent and can be a linear, branched, cyclic, aromatic or any combination thereof of saturated or unsaturated C ⁇ to C 2 o group and any C2-C20 carbon atom can be replaced with a heiero-atom selected from the group consisting of O, S and N,
- Preferred amine oxides are alkyl dimethyl amine oxides such, as decyl dimethyl amine oxide, !auryl dimethyl amine oxide, isoalkyl dimethyl amine oxide, myristyl dimethyl amine oxide, cetyl dimethyl amine oxide, stearyl dimethyl amine oxide and octyl dimethyl amine oxide. Most preferred is N-alkyl (C 12 -C 16 )-N,N-dimethylamine oxide (ADO),
- a buffering agent can be defined as an aqueous solution consisting of a mixture of a weak acid and its conjugate base or its weak base and conj ugate acid. It has a property that the pH of the solution changes very little when a small amount of strong acid or strong base is added. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide range of chemical operations. In the present invention, the buffer helps to maintain a neutral-to- basic pH in the presence of the acids naturally present in the wood. As the pH of wood is typically around 5.4, the preferred buffering capacity should be above a pH of 5.4 in order to achieve maximum penetration.
- a dual buffering system generally consists of two different buffering agents, each with their own weak acid/conjugate base or weak base/conjugate acid or weak acid/weak base pairs, which combine to provide the desired pH.
- a solution contains one or more amine oxides along with a buffering agent and at least one wood preservative with the solution having a pH of about 5 to 12.4 and preferably about 7 to 10 and most preferably about 7 to 8.5.
- the materials may be provided in concentrate form in a solution of a suitable solvent, such as water, with the final solution to be applied being created by adding additional solvent and mixing the same in order to minimize shipping and storing of the solvent volume required to make up the difference between the concentrate solvent volume and the final solution solvent volume.

- the wood preservative is present in about 3 ppm to 50 weight percent based on weight of total solution and preferably about 20 ppm to 5,000 ppm.
- the solution is in water or another suitable solvent such, as ethanol or ethylene glycol, for example.
- the materials may be provided in the form of a concentrate which will be diluted prior to application to achieve the foregoing relationships.
- the solution is applied to the wood by any desired means such as spraying, roiling on or dipping, for example. If desired, amounts of pressure or vacuum without totally filling the wood with liquid could be employed.
- the wood so treated may be stored for a period of time before activation or may be activated promptly thereafter by treatment at an elevated temperature in a high relative humidity environment.
- Application may be achieved at any temperature between ambient and boiling temperature, hut in the preferred approach to the invention, the application will be achieved at a temperature of about 30°C to 75°C and preferably at a temperature of about 50°C to 60°C.
- Activation is preferably achieved over a period of at least 8 hours at ambient temperature to steam temperature and preferably at about 70°C to 95°C and at a relative humidity of about 60 to 100% and preferably about 80 to 100%, It is preferred to preheat the wood to about 8°C to 230°C and most preferably at about 12°C to 100°C.
- buffering agent amine oxide or wood preservative
- amine oxide or wood preservative may be employed and the ranges set forth herein refer to each category with a single compound or a combination of compounds.
- the balance of the solution may be a suitable solvent such as water, ethanol or ethylene glycol, for example, or any desired additives such as water repellants, waxes, such as paraffin wax, for example, polymers, silicones and. combinations thereof.
- a suitable wax-polymer emulsion is that sold under the trademark WRS-3 by Kop-Coat, Inc.
- a suitable coloring agent such as an iron oxide pigment dispersion, red dye or phantom blue dye as offered under the trade designation Day Glo or others may be employed,
- glycols and other additives which help soiubilize materials such as the buffering agent, amine oxides, wood preservatives, water repellants and the like may be employed,
- additives such as glycols and alcohols which serve as solvents and may be employed in quantities of about 5 to 40 weight percent based on total solution.
- suitable glycols are ethylene glycol, propylene glycol or polyethylene glycol.
- the process of the present invention has been found to provide deeper and more rapid penetration than processes which do not employ such a solution. Enhanced performance may be achieved by applying heat to the wood before or after application or to the solution or by combinations thereof. The solution also may be applied without requiring prior art pressure impregnation or the use of vacuum conditions or undesirable, potentially health-hazardous and environmentally undesirable volatile solvents such as petroleum distillates.
- wood preservatives usable in the present invention are 3 ⁇ iodo-2-propynyl butyl carbamate (IPBC), diiodomethyl-p-tolylsulfone (DIMPTS), halogenated organics, azoles, quaternary ammonium compounds, isothiazalones, metallic organics, borates, copper naphthenate, copper oxide, copper carbonate, tributyltin oxide, zinc omadine, salts of organics and metallorgamcs.

Those skilled in the art will know well the conventional quantities of fungicides to be introduced into the wood.
- the wood to which the solution has been applied may be stacked and penetration attained by wrapping the warm., freshly coated substrate stacks in an air-impervious material such as a suitable resinous plastic sheet and allowing it to stand at ambient temperature for 8 hours to three days. Additional penetration may be achieved thereafter through the activation process.
- an air-impervious material such as a suitable resinous plastic sheet
- Another benefit of the present invention is that the wood surface appears to be clean and dry with no substantial undesirable grain raising
- the method of the present invention may be practiced in an in-line manner to process the wood efficiently while avoiding undesired forces such as would exist in pressurized treatment, which may cause a straight board to depart from its desired straight configuration.
- the wood may also be engineered wood or laminated wood having a glued layer or substantial amount of glue or resin therein with the method effecting penetration of the wood preservative through the glue or resin.
- the method may be performed on wood with any amount of moisture content including green (wet.) wood and on wood which has moisture at a level which does not exceed the fiber saturation point of the wood and on dry wood.
- Various buffering systems were prepared by dissolving the appropriate reagents into one liter of deionized water. All buffering solutions were formulated to be between 0,5 molar and 1.0 molar in their final concentrations. Table 1 recites the composition of the buffering systems used in this study.
- a treating concentrate was prepared as outlined in Table 2. The buffering systems were then combined with the treating concentrate and deionized w r ater to make 2 liters of treatment solution. The composition of each treatment solution is given in Table 3.
- TIMBERTREAT D-282 is an ultraviolet, optical brightener, which is a dye
- TIMBERTREAT D is a trademark for an IPBC which functions as a fungicide.
- TIMBERTREAT ICP-5 is a trademark for permethrin, which functions as an insecticide.
- WOODTREAT 10 is a trademark for propiconazole, which functions fungicide.
- Table 3 shows the composition of the treating solution with the buffer system identified in the left-hand column followed by the weight percent buffer (Table I), the weight percent treating concentrate (Table 2), and the weight percent water.
- ⁇ ' thick cross sections were cut 4" from the sealed end of each board for measurement of penetration of active ingredients. Each cross section was then heated in an oven at 175°C for ten minutes. After removal from the oven, a bromophenol blue indicator solution (0.4%) was applied to each cross sectional face.
- the bromophenol blue indicator changes color from light green to dark blue in the presence of the amine oxides present in the treating solution, As a result, the degree of penetration of the amine oxides can be monitored by noting the depth of the dark blue color present in each cross sectional face.
- a marker was used to trace the depth of penetration of the amine oxide toward the center of each sample, A calibrated micrometer was then used to measure the distance between the edge of the sample and the marker space. The distances are indicated by zone numbers with zone 1 being the outermost zone, zone 2 being the next innermost zone, and zone 3 being the innermost zone.
- Penetration to the line between the two zone 3 regions would be regarded as 100% penetration.
- Two measurements (in inches) were made per side by determining the two deepest penetration points, Two separate measurements were used to assure that no one maximum would skew the results on a given sample of wood.
- Five samples of wood were measured for each treatment, and the results were then averaged. Since ail samples had a cross-sectional thickness of 0.755 inch, full penetration to the center of the piece would be 0.378 inch.
- the sample without buffer penetrated 0.210 inch Considering as a standard system the sodium borate/boric acid at a pH of 7.6, which is slightly basic, the penetration was 0330 inch or 87%.
- a third series of tests were conducted employing the same methods as discussed above.
- the purpose of the third study was twofold - to expand the buffering systems in the basic pH range and to demonstrate the ability of some of the systems to achieve 100% penetration of the substrate.
- Basic buffering systems were prepared using the method described above.
- the dual buffer system, although not basic, was included in the study to evaluate its effectiveness. These were then combined with water and the treating concentrate in the ratios described in Table 3 and used to treat the Radiata Pine boards as described in the experimental method, in this third series, the main difference was that the activation period was increased from 24 hours to 120 hours.
