Problems solved by technology

At present, the adhesives for fine grinding belts in the domestic market are composed of phenolic resin, dispersant, thinner, etc., and phenolic resin has its own insurmountable shortcomings: high brittleness and poor flexibility, so that the existing fine grinding belts The adhesives in the grinding process The medium strength is not high, the heat resistance and flexibility are not good, and the heat dissipation is not fast, so that the abrasive debris is not easy to separate from the abrasive grains, resulting in poor self-sharpening of the abrasive grains
Therefore, the existing fine grinding abrasive belts have short service life, low work efficiency, low frequency of grit renewal and grinding during operation, and are easy to scratch the surface of the workpiece.

Abstract

The invention relates to an abrasive belt, a semi-friable alumina finishing abrasive belt in detail. The abrasive belt consists of a fabric base, an adhesive and grinding material, wherein the grinding material is the semi-friable alumina and usually is adhered to the fabric base by the adhesive. The abrasive belt is characterized in that the adhesive consists of the following components of the specific weight percentage: 36percentage-40percentage A-stage thermosetting phenolic resin; 4 percentage-5.5 percentage diphenol-propane epoxy resin; 1.8 percentage-2.8 percentage melamine resin; 0.1 percentage-0.6 percentage boron; 0.1 percentage-0.3 percentage dispersant; 0.1 percentage-0.3 percentage resin acceptor; 2 percentage-6 percentage thinner;18 percentage-26 percentage calcium carbonate; 18 percentage-26 percentage fluoride salt; and 0.1 percentage-0.5 percentage inert gas fluoride. The adhesive of the invention equips with sufficient strength, excellent heat resistance and necessary flexibility in the grinding process. The finishing abrasive belt combined with the semi-friable alumina has the advantages of good sharpness and high hardness, thus improving the degree of finish and precision of the work-pieces requiring processing.

Description

technical field [0001] The invention relates to an abrasive belt, in particular to a semi-brittle corundum fine abrasive belt. Background technique [0002] With the rapid development of the machinery industry, the requirements for coated abrasive products are getting higher and higher, and the consumption is also increasing. In the grinding process of the surface treatment of metal structural parts, various requirements are also put forward for the grinding of the workpiece to be ground. [0003] Economically developed countries such as Japan and South Korea have produced fine grinding abrasive belt products that can prevent scratches on the surface of the ground workpiece and have high processing accuracy. Precisely process the surface of metal products. At present, the fine grinding belts produced by domestic manufacturers have the defects that the surface of the base material is relatively moist, the heat dissipation of the resin is not fast, the abrasive particles are ...
