Problems solved by technology

[0004] In the above-mentioned patents, only resin is used as a binder, and no toughness-enhancing components are added. The toughness and bending resistance of the grinding block are poor. After the grinding block is formed, it is easy to break when it is subjected to cutting force, resulting in a short life.

Abstract

The invention discloses a diamond resin grinding slice material and a preparation method thereof, and relates to the technical field of grinding materials. The technical scheme includes that the diamond resin grinding slice material comprises, in weight percent, 3-8% of diamond, 10-15% of cashew nut oil modified phenolic resin, 5-12% of stainless steel powder, 5-15% of copper fibers, 5-10% of auxiliary abrasive and the balance melamine formaldehyde resin molding powder, and the total weight percent is 100%. According to the material, the cashew nut oil modified phenolic resin and the melamineformaldehyde resin molding powder are matched to serve as an adhesive of a grinding block, the toughness of the grinding block can be improved, friction resistance is enhanced, and bending strength and abrasion resistance are further enhanced after the copper fibers are added.

Description

technical field [0001] The invention relates to the technical field of abrasive materials, more specifically, it relates to a diamond resin abrasive material and a preparation method thereof. Background technique [0002] The diamond resin abrasive block is made of resin as the binder and diamond as the abrasive grain. Compared with the traditional abrasive block, the diamond resin abrasive block has the advantages of good sharpness, high processing efficiency and long service life. There is no need for frequent shutdowns, and the labor intensity of production employees is low. [0003] In the Chinese invention patent whose publication number is CN106956226A, a composite grinding block and its preparation method are disclosed. The composite grinding block includes a deck and a grinding head, and the grinding head is made of resin abrasives and magnesite abrasives. Composition, the magnesite abrasive is arranged on the periphery of the corresponding resin abrasive. The resi...
