Special collision-resistance and modification microcrystalline ceramic abrasive material for machine tool industry, and manufacturing method thereof

Abstract

The invention discloses a special collision-resistance and modification microcrystalline ceramic abrasive material for machine tool industry, and a manufacturing method thereof. The microcrystalline ceramic abrasive material comprises two parts, wherein the first part is a microcrystalline ceramic formed by sintering alumina powder, lanthanum nitrate hexahydrate and hydroxyapatite in a shuttle kiln, the second part is obtained by polymerizing three components A, B and C, the component A is a mixture of a vinyl olefin-based unsaturated monomer, a phosphorus bidentate ligand, lead powder, activecarbon powder and titanium dioxide powder, the component B is an acrylate-based olefin-based unsaturated monomer, the component C is a sodium silicate aqueous solution with a solute mass fraction of10%, and the second part is a microcapsule structure using the lead powder, the active carbon powder and the titanium dioxide powder as a core, using a silicic acid gel as a medium, and using the vinyl olefin-based unsaturated monomer and acrylate-based olefin-based unsaturated monomer polymer as a mold shell. According to the present invention, the special collision-resistance and modification microcrystalline ceramic abrasive material has characteristics of microcrystalline structure, fine and dense grinding blade, high strength, good toughness, self-loss resistance 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.
