Abstract

The invention relates to a rubber thin sheet grinding wheel and a preparation method thereof. The rubber thin sheet grinding wheel comprises the following raw materials in part by weight: 4 to 6 parts of natural rubber emulsion, 0.5 to 1.5 parts of zinc oxide, 4 to 6 parts of sulfur, 0.5 to 2.5 parts of epoxy resin, 0.4 to 0.6 part of anti-ager, 0.3 to 0.7 part of accelerant, 6 to 8 parts of silicon carbide, 2 to 4 parts of diamantane, 2 to 4 parts of chromium corundum, 1 to 3 parts of resin powder, 0.5 to 1.5 parts of resin liquid and 3 to 5 parts of coagulator. The rubber thin sheet grinding wheel of the invention has the advantages of high wear resistance, heat resistance, self-sharpening property, heat conductivity, corrosion resistance, toughness, hardness and working efficiency and long service life; in addition, the rubber thin sheet grinding wheel prepared by the preparation method of the rubber thin sheet grinding wheel of the invention is very thin and has low loss and high accuracy during cutting.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a rubber sheet grinding wheel and a preparation method thereof. Background technique [0002] Many workpieces often need to be ground and trimmed with grinding wheels after the processes such as casting, welding, processing and maintenance are completed. The grinding wheel is bonded together by numerous small abrasive grains through the bonding agent. Since the abrasive grains are relatively hard, the bonding layer between the abrasive grains is very thin, resulting in almost rigid contact between the abrasive grains. Therefore, the grinding wheel has a high Excellent rigidity, grinding ability and grinding efficiency, but this kind of grinding wheel makes the surface of the workpiece to be ground prone to scratches, and it is difficult to obtain better surface processing quality. Chinese patent application 200810049094.6 proposes a rubber elastic grinding wheel, which not only has good hardn...
