A kind of anti-collision and modified microcrystalline ceramic abrasive for machine tool industry and its manufacturing method

Abstract

The invention discloses a special microcrystalline ceramic abrasive for anti-collision and modified machine tool industry and its manufacturing method. The special microcrystalline ceramic abrasive for machine tool industry consists of two parts, wherein the first part is aluminum oxide powder, lanthanum nitrate hexahydrate, Microcrystalline ceramics obtained by microcrystalline sintering of hydroxyapatite in a shuttle kiln; the second part is obtained by polymerization of three components, component A is vinyl ethylenically unsaturated monomer, phosphorus bidentate ligand , lead powder, activated carbon powder, and titanium dioxide powder are a mixture of raw materials; component B is an acrylate-based ethylenically unsaturated monomer; component C is an aqueous solution of sodium bicarbonate containing a solute mass fraction of 10%, and the second part The composition relationship is a microstructure with lead powder, activated carbon powder and titanium dioxide powder as the core, silicic acid gel as the medium, vinyl ethylenically unsaturated monomer and acrylate-based ethylenically unsaturated monomer polymer as the shell. Capsule structure. The invention has the technical effects of microcrystalline structure, fine and dense grinding blade, high strength, good toughness, self-wearing prevention and durability.

Description

technical field [0001] The invention relates to the technical field of ceramic abrasives in the mechanical industry, in particular to a special microcrystalline ceramic abrasive for anti-collision and modified machine tool industry and a manufacturing method thereof. Background technique [0002] At present, the corundum abrasive materials (such as cutting discs, grinding wheels, and emery cloths) used in the machine tool industry in the prior art have only one-time use sharpness and cutting force, and there is no self-sharpening of the subsurface after the surface layer is broken and stable cutting force. At the same time, most of the grinding loss is not even caused by the grinding itself, but the unnecessary loss caused by the poor bonding force between the corundum and the instability of the matrix due to mutual collision and wear. [0003] For polishing and abrasive materials, it mainly refers to the selection of grinding media, which is closely related to the material ...

Problems solved by technology

At present, the vast majority of my country's corundum abrasives are manufactured using the traditional electric melting process, and the corundum abrasives produced by the sintering method are rarely produced. Similarly, the quality of SG abrasives is still far behind that of developed countries.
