The specific embodiment
Grinding-material of the present invention can be formed by any easy etched material, for example comprises stainless steel, carbon steel, aluminium alloy, iron-nickel-chromium and titanium; Fill boron elastomer, silicon synthetic, fluoro carbon materials, graphite alloy, plastics and analog.
In the present invention, stainless steel is particularly preferred base material, because its intrinsic material corrosion resistance, good high-temperature and excellent low temperature intensity and toughness, other non-magnetic characteristic of austenite level and aesthstic outward appearance in wide temperature range very.Stainless steel also can easily repeat to be etched with formation grinding-material of the present invention.
The thickness of material is not particularly limited, but after etching, should have suitable flexibility when it is used on the roller, perhaps should have suitable rigidity when being used as flat grinding agent.Certainly, if necessary can provide rigidity, for example metallic plate or synthetic resin board with suitable rigidity by the additional rigidity substrate.
Include but not limited to nickel or the plating that chromium is electroplated or diamond plates or combine boron nitride and diamond sand for the especially preferred exemplary surface treatment of stainless steel-based bottom material.Substrate and pyramidal projections can be exposed to heat treatment or metallurgical modification (metalluricalalteration), and for example surface sclerosis for example influences case hardness with what approach by formation on substrate surface and projection than hard formation, to improve performance.
With reference to the accompanying drawings, identical reference number is used to represent identical parts.Figure 1A, 1B and 1C show the different possible embodiment of the pyramidal projections of grinding-material of the present invention, and wherein the substrate of pyramidal projections is respectively triangle, square and pentagon.Certainly, other polygons also can use.In Figure 1A, show projection 10a and have triangular base 12a, triangle side 14a and pinnacle 16a.In Figure 1B, show projection 10b and have square base 12b, triangle side 14b and pinnacle 16b.In Fig. 1 C, show projection 10c and have polygon substrate 12c, triangle side 14c and pinnacle 16c.
The degree of depth of the inside actuate slopes on the triangle side of projection can be from very little, and for example 1 μ m arrives about 175 μ m greatly.This actuate slopes can easily find out in Fig. 2 and Fig. 3, and pyramid 20 has and intersects at top 26 actuate slopes 24a among Fig. 2, and mountain buttress 21 has the actuate slopes 24d that intersects at step 28 among Fig. 3.The size of projection is big more, and the inside actuate slopes that can form is dark more.
Preferably, the height H apart from etched surfaces of pyramid and mountain buttress can be at about 25 μ m between the 1.5mm scope, higher pyramidal projections is used for conventional coarse grinding, just from about 125 μ m to 375 μ m, lower pyramidal projections is used for fine gtinding, just from about 75 μ m to 125 μ m.The length L at the edge of substrate depends on the height of projection.Preferably, projection between about 1: 1 to 1: 5, more preferably is apart from the length ratio of the height of etched surfaces and basal edge between about 1: 2 to 1: 4, most preferably is about 1: 3.The thickness B of residual substrate material can vary widely very much, and is unessential, and thin base material is used for more flexible grinding-material, and thicker base material is used for harder grinding-material, just as is known to the person skilled in the art.This size has illustrated in the pyramid of grinding-material of the present invention, sees the cross section among Fig. 5.
The interval S of pyramid and mountain buttress also can very broadly change, from the center to center measurement of pyramidal projections is to 30mm from about 0.75mm, be used for coarse grinding than large-spacing, just 2 to 10mm or greater distance, and the more closely-spaced fine gtinding that is used for, just at interval from about 0.75 to 1.5mm.
The length of the height that the meticulous or roughness of grinding-material also can be by keeping projection and the substrate of projection and the size of adjusting resist pattern are adjusted.Bigger interval provides more coarse grinding-material between the projection, and less interval provides than the fine gtinding material between the projection simultaneously.
The photoresist mask that is suitable for the fine gtinding sand grains has been shown among Fig. 4 A.
Importantly, pyramidal projections is directed like this, that is, make the cut edge of each projection locate in different directions, so that the ability of the grinding that is independent of service orientation to be provided.Pyramidal projections is random orientation in different directions, and for example the stochastic programming device by the basis that uses a computer comes the design etched mask, perhaps etching mask can Butut to guarantee the known random position of those skilled in the art.The example of random orientation pattern has been shown among Fig. 4 A, 4B, 4C and the 4D.
As previously described, electroplate as nickel or chromium; Diamond coatings; Perhaps nickel that combines with diamond grain or teflon (Teflon), tungsten, carbide or boron nitride particle or chromium are electroplated the surface that such coating can be applied to grinding-material as shown in Figure 5, wherein, grinding-material 59 part has projection 52, residual substrate part 54 and coating 56.
Etch process can use the against corrosion and etching material and the technology that are widely known by the people to implement.Before photoresist is applied to base material, preferably implement the cleaning of base material.If base material is a stainless steel, this cleaning can comprise the cleaning and the drying of carrying out with deionized water.As selection, perhaps except this cleaning, stainless steel surfaces also can be subjected to float stone shampooing or Passivation Treatment.If have, free iron contaminants is realized by iron chloride, nitric acid or other solution well known by persons skilled in the art usually together with the passivation that other pollutants remove.
Etch-resistant coating can use that for example hot-roll lamination, serigraphy, photogravure, dip coated and similar fashion are used.When resist put on stainless steel-based bottom material with the polymer thin film form, base material preferably was preheated and film uses fully heat and pressure to use, and is good bonding to guarantee.In processing procedure this must be avoided the curing of resist constantly.
The mask that is used to provide the abrasive pattern surface of expection is placed on the base material of resist covering then.Need the good contact between resist coating and the mask, closely contact just is to obtain the pattern of expection on base material when the photoresist that does not have mask to cover is cured.
Curing or imaging realize the resist of interlinkage polymerization just by being exposed in the light that is enough to solidify.Mask removes from base material/photoresist/mask synthetic then, and uncured photoresist uses developer solution or developer to remove from base material.The composition of photoresist is depended in the selection of developer.If expectation, the photoresist that is retained in then on the base material can imaging once more before etching, is bonded on the base material well at photoresist during the etching further guaranteeing.
Those of base material are not subjected to the part of photoresist protection to implement etching then.Give an example, when substrate was stainless steel, carbon steel or analog, suitable etchant comprised the mixture of iron chloride, hydrochloric acid, hydrofluoric acid, nitric acid, these acid and NaOH; For aluminum or aluminum alloy, suitable etchant comprises NaOH; For titanium, suitable etchant comprises hydrofluoric acid; And plastics can use multiple acid to come etching usually.The etching degree can be adjusted by the concentration and the temperature that change etching solution, and implementation method is that those skilled in the art are known.Give an example, when these base materials or substrate when being stainless, can use the aqueous ferric solution of about 37 ° to 42 ° Baume degrees (Baume), the solution Baume degrees is low more, usually the inclined-plane of outstanding sidepiece bow action more just.
After being etched with, any remaining photoresist can randomly remove by well known to a person skilled in the art technology.Under the situation of some mask pattern and etching parameter, much these photoresists are removed in etching process.Removing of residue photoresist is normally preferred, is particularly electroplated and photoresist when can be used as platedresist when pyramidal projections.
As selection, resist can be retained on the surface of grinding-material of generation, is retained in the non-abrasive side of material when particularly ought have only a side crested and pattern etched, and this can prevent crimping.The proper method that prevents crimping comprises the both sides of etching base material as shown in Figure 6, and wherein, grinding-material 60 has projection 62a, the 62b that extends from residual substrate material 64 on each surface 61,63.
Purpose of the present invention and advantage are further set forth by following example, but special material and the quantity quoted in these examples, and other conditions and details should not constitute the unsuitable restriction to the present invention.Except as otherwise noted, all branches and percentage are as the criterion with weight.
