Diamond abrasive of elastic abrasion block used for grinding and polishing nonmetal concave and convex surfaces

Abstract

A diamond abrasive of an elastic abrasion block used for grinding and polishing nonmetal concave and convex surfaces is disclosed. The diamond abrasive is characterized in that: the diamond abrasive comprises 40-50% by mass of phenolic resin, 5-8% by mass of polyvinyl butyral, 2-3% by mass of chromic oxide, 6-8% by mass of cerium oxide, 6-8% by mass of aluminium oxide, 3-6% by mass of zinc oxide, 20-30% by mass of silicon carbide and 5-10% by mass of diamond; and the raw materials are fully mixed, subjected to mould pressing and sizing at 156-160 DEG C, and cured at 130-145 DEG C. The diamond abrasive is characterized in that: by adding the polyvinyl butyral, brittleness of the phenolic resin is changed, and flexibility and toughness are enhanced, thus avoiding edge breakage and surface breakage of the abrasive during grinding and polishing, eliminating abrasion scratches caused by scratches of ceramic glazes by edge breakage points and surface breakage points of the abrasive and prolonging the service lifetime of the abrasion block.

Description

technical field

[0001] The invention belongs to polishing materials such as ceramics and stone materials, and in particular relates to a diamond abrasive for elastic grinding blocks used for grinding and polishing non-metal concave-convex surfaces. Background technique

[0002] At present, for the grinding and polishing of non-metallic materials with concave-convex surfaces, such as glazed ceramic tiles, elastic abrasive blocks are usually used. The elastic grinding block is composed of a collet and an elastic material and diamond abrasive fixed on the collet. Due to the inherent defects of diamond abrasives, chipping and surface chipping are prone to occur during the grinding and polishing process of glazed ceramic tiles, resulting in the grinding of the glazed surface of the product and affecting the quality of the product.
