It is characterized by that it adopts the bisque powder as main raw material through the following steps: drying said bisque powder, adding water and stirring, adding ammonium nitrate, zinc nitrate and silver nitrate aqueous solution, stirring them, cleaning, filtering, drying and pulverizing so as to obtain the product. It is stable in performance, can resist high-temp. and its production process is simple, low in cost and its application is extensive.
Description
Technical field
The present invention relates to a kind of inorganic antiseptic and production technology thereof, belong to that products such as being used for plastics, pottery, enamel, coating, paper, weaving, washing is antibiotic, the additive of mildew-resistant.
Background technology
The antibacterial agent that uses divides organic and inorganic two big classes at present, and the general temperature tolerance of organic antibacterial agent is poor, facile hydrolysis, and the term of validity is short; And inorganic antiseptic one is to adopt directly to add noble metal in product, and the cost height influences product appearance quality and physicochemical property; The 2nd, be supported in the carrier with metal ions such as gold, silver, copper, zinc, titaniums, again carrier is added in the high molecular products.This carrier has contact-type and light to touch type, and contact-type is the adsorption of metal ions bacterium by product surface, and the enzyme on the bacterium is transformed, and loses activity and death; It is to utilize the luminous energy induced chemical reaction and sterilize that light touches type.But their complex manufacturing, the price height, heatproof is lower.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of inorganic antiseptic and production technology thereof are provided, it adopts the bique powder to add slaine and is made, and raw material is easy to get, low price, and technology is simple, and is pollution-free, and physicochemical property is stable, and is high temperature resistant.
The object of the present invention is achieved like this: its component and percentage by weight are: bique powder 19.87-21.96, water 5.5-7,0.5-2mol/L ammonium nitrate 5-6,0.1-1.0 mol/L zinc nitrate 4-5.5,0.01-5mol/L silver nitrate 0.5-0.9, water 60-63.
Its production technology is: earlier bique is cleaned up, do not have native free from admixture, pulverize and grind to form the bique powder that granularity is 1.5 μ m-10 μ m; Percentage by weight is got a certain amount of bique powder and is dried under 120-200 ℃ of temperature in accordance with regulations then; The water furnishing pastel that adds ormal weight is put into stirred tank and was stirred exhaust 0.5-1 hour; Measure the Acidity of Aikalinity of the bique powder after stirring, add aqueous slkali or acid solution respectively, continue to stir 0.5-1 hour, be adjusted to PH=5-7; With the concentration of ormal weight is that 0.5-2mol/L ammonium nitrate, concentration are that 0.1-1.0mol/L zinc nitrate, concentration are that 0.01-5mol/L silver nitrate and water mix, add in the bique powder of above-mentioned pasty state, keep 30-70 ℃ of temperature, continue to stir 8-24 hour, this process silver and zinc ion are adsorbed to the surface of bique powder, play antibacterial functions, ammonium ion then plays the effect of protection silver and zinc ion, makes the unlikely variable color of the present invention; Then room temperature water is added cleaning and filtering in the stirred tank, use 30-60 ℃ water cleaning and filtering two to three times again, oven dry, and be ground into powder, the moisture barrier bag of packing into is finished product.The bique that the present invention uses is generally selected the discarded semi-finished product that do not meet the ceramic product quality of ceramic producer for use.Its component is the clay of 40-60%, the quartz of 25-40% and the feldspar of 8-15%; Its main chemical constituent is: the SiO of 75-77%
2, 20-22% AL
2O
3, 0.2-0.4% Fe
2O
3, 0.3-0.5% MgO, the K of 1-1.8% of CaO, 0.1-0.25%
2The Na of O, 0.2-0.45%
2O.
Regulate pH value, available salpeter solution or sodium hydroxide solution.
Compared with prior art, the present invention has the following advantages:
1, physicochemical property is stable, and is high temperature resistant
The used bique of the present invention is all burnt till through 1200 ℃, impurity seldom, quality is pure, and bigger absorption property and acid-proof alkaline are arranged, so adsorptivity of the present invention is strong, is applicable to higher temperature and stable performance.
2, low price is easy to get
The used bique major part of the present invention is the waste material that producer abandons, and inexhaustible, so price of the present invention is very cheap.
3, easy to process, technology is simple, Device-General
The present invention is ultra-fine from bique, to stirring, cleaning, the equal useful ceramics of oven dry factory raw material processing, does not have especial equipment requirements, has effectively reduced investment in production equipment, and simple and convenient processing method, is convenient to produce.
4, pollution-free, safety
The raw material that the present invention uses all is nontoxic, tasteless mineral salt, and all harmless to people, animal etc., production safety is pollution-free, has also effectively solved the pollution of the useless bique rubbish of producer to social environment simultaneously.
Embodiment
It is the proportioning weight (gram) of each component in five kinds of embodiments in 1000 whens gram that following table has been listed with the composition weight summation:
| Embodiment | The bique powder | Water | Ammonium nitrate | Zinc nitrate | Silver nitrate | Water |
| ????1 | ????210 | ????60 | ????60 | ????50 | ????8 | ????612 |
| ????2 | ????199 | ????55 | ????58 | ????55 | ????5 | ????628 |
| ????3 | ????200 | ????65 | ????60 | ????40 | ????5 | ????630 |
