Technical field
The present invention relates to a kind of resin abrasive tools, relate in particular to a kind of compound multipurpose resin abrasive tools, the invention still further relates to the preparation method of this compound multipurpose resin abrasive tools.
Background technology
Resin abrasive tools is known as industrial tooth, and application is very extensive, but resin abrasive tools function in the market is single type mostly, can only be used for certain material.And work as the user in order to finish a certain work, need cut or when polishing multiple material, will use multiple grinding tool at different materials, so not only need to buy multiple grinding tool, certain human and material resources, the waste of financial resources have been caused, and also to change grinding tool frequently when using, extremely inconvenient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of compound multipurpose resin abrasive tools and preparation method thereof, this kind grinding tool of the present invention can be used for the cutting polishing of multiple materials such as metal, alloy, stone material, and is of many uses, usability price ratio height.
For solving above technical problem, the technical scheme that the present invention takes is:
A kind of compound multipurpose resin abrasive tools, comprise enhancement layer and grinding layer, wherein said grinding layer is prepared from by weight 80-140:15-30:3-15:1-8:0.5-2 by abrasive material, bond, filler, functional material and pigment, and wherein said functional material is polyethylene wax micro mist.
Further, described abrasive material is that brown corundum, white fused alumina, carborundum mix by weight 40-60:30-40:10-40.
Further, described bond is liquid phenolic resin and phenol-formaldehyde resin powder, and its weight ratio is 1:1.5-2.5.
Further, described filler is at least a in ice crystal, troilite, barite, the magnesia.
The preparation method of this compound multipurpose resin abrasive tools may further comprise the steps:
A) batch mixing: abrasive material and liquid phenolic resin are mixed in batch mixing pot A, filler, functional material, pigment and phenol-formaldehyde resin powder are mixed in batch mixing pot B, again the mixture of mixing among the batch mixing pot A is poured among the batch mixing pot B with B in mixture mix stand-by;
B) moulding: adopt twice stand material, die press technology for forming, half material of stand earlier in mould is put into the glass screen cloth again, and second half material is gone at the stand again, compression moulding after the stand material is finished;
C) solidify: the base substrate of compression moulding is put into kiln drying, curing.
Further, described briquetting pressure is 4-8Mpa.
Further, described forming temperature is 50-60 ℃.
Further, the described moulding press time is 3-5 second.
Further, described baking temperature is 105 ℃, and the time is 2.5 hours.
Further, described solidification process is three sections curing, and described solidification temperature is warming up to 185-190 ℃ piecemeal from 105 ℃, and solidifying total time is 20 hours.Wherein three sections solidify section and are respectively: first solidifies section, and design temperature is 135 ℃, and temperature rises to 135 ℃ from 105 ℃, is incubated 4 hours; Second solidifies section, and design temperature is 150 ℃, and temperature rises to 150 ℃ from 135 ℃, be incubated 6 hours, and the 3rd solidifies section, and design temperature is the arbitrary temperature between 185-190 ℃, and temperature rises to design temperature from 150 ℃, is incubated 10 hours.
Further, in the above-mentioned preparation process, the glass screen cloth that uses is 6 orders as the enhancement layer of grinding tool, its specification, 96mm*17mm, 190 grams.
Adopting the density of the compound multipurpose resin abrasive tools that preparation method of the present invention prepares is 2.45g/cm
3, the base substrate thickness of moulding is 2.4 ± 0.1mm.
Compared with prior art, the invention has the beneficial effects as follows:
Because the functional material polyethylene wax micro mist that has added in the grinding layer of resin abrasive tools of the present invention, the heat that produces in the process of grinding tool cutting polishing can make the fusion of wax powder, the wax powder viscosity of fusion is very low, has good resistance to bond, make material such as soft metal can not stick on the mould, thereby realize the cutting polishing of materials such as soft metal; The abrasive material of this grinding tool adopts the composite abrasive compound of brown corundum, white fused alumina and three kinds of abrasive materials of carborundum simultaneously, and the polyethylene wax micro mist that adds can not influence intensity and other performance of grinding tool, therefore the grinding tool that forms like this can be used for the cutting polishing of multiple materials such as carbon steel, stainless steel, cast iron, aluminium, copper material, stone material, such grinding tool can be finished multiple cutting polishing work simultaneously, not only easy to use, need not frequently change grinding tool, and improved the cost performance that grinding tool is bought greatly, have a good application prospect.
