Preparing method for toughening-wear-proof abrasive material

Abstract

The invention discloses a preparing method for a toughening-wear-proof abrasive material, and belongs to the technical field of abrasive material preparation. According to the preparing method, in thefermentation process of rice hull ash, nitrogen in ammonia gas is fixed in fermentation filter residues through the micro-corrosion effect of microorganisms in pericarp, and nitrogen-containing composite powder and boron-containing ceramic bond are mixed to be subjected to hot pressing sintering to form a hexagonal boron nitride crystal. In the process of preparing diamond-silicon carbide composite powder, the rice-hull-ash-containing fermentation filter residues are reduced and carbonized on the surface of diamond, compact silicon carbide is formed on the surface of the diamond, air holes can contain abrasive scraps, the exposure rate of the abrasive material in the abrasive process is higher, crystal whiskers can be generated through magnesium mine powder and boric acid in the sinteringreaction process, and can prevent the air holes from being oversize, and the toughness of the abrasive material is improved. According to the preparing method for the toughening-wear-proof abrasive material, the holding force of the bond in a man-made abrasive material for the abrasive material is improved at suitable air hole rate, the wear-proof performance of the man-made abrasive material isimproved accordingly, abrasion is reduced, and application prospects are broad.

Description

technical field [0001] The invention discloses a preparation method of a toughened wear-resistant abrasive material, which belongs to the technical field of abrasive material preparation. Background technique [0002] Abrasive materials are the general term for coated abrasives, wire drawing abrasives, and polishing abrasives, which are mainly used for grinding, wire drawing and polishing on the surface of workpieces. Abrasive materials belong to the "hardware tool" category. [0003] Abrasive materials in abrasive materials usually include: Coated types: steel paper abrasive discs, sandpaper, abrasive belts. Nylon type: industrial scouring pad, nylon ring belt, nylon wheel, flying wing wheel. Polishing: ceramic sand, polishing wax, polishing paste, cloth folding wheel, linen wheel, polishing liquid and other abrasive materials. Abrasive materials are mainly used for material polishing, and can be used for polishing glass, metal, leather, semiconductors, plastics, gemston...

AI Technical Summary

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that the abrasive materials currently used are generally alumina, zirconia, diamond, silicon oxide, cerium oxide, titanium oxide, silicon nitride, etc., and the damage to the polishing surface is serious during the polishing process, and the wear Large amount will not only cause large surface roughness, but also prone to surface defects such as polishing scratches and pits. Due to the high brittleness of the abrasive grains of traditional abrasives, the cutting edge is easily broken during grinding, poor toughness, and high wear. The defect of relatively short service life provides a preparation method of toughened and wear-resistant abrasive materials
