Resin bendable grinding wheel and preparation method and device

Abstract

The invention discloses a resin bendable grinding wheel and a preparation method and a device thereof. The resin bendable grinding wheel consists of brown aluminium oxide, calcined alumina, white alundum, black silicon carbide, phenolic resin powder, phenolic resin liquid, cryolite, barium sulphate, pyretic, iron oxide red, Hunori gel, alkali-free high tensile glass fiber mesh and non-woven black cloth. Compared with the prior art, through the optimization configuration on the aspect of the material selection and working procedures, the strength, the flexibility and the aging resistance of the grinding wheel are greatly improved, and at the same time, the resource and the energy are saved; and the strength of the grinding wheel is more than 80m/s, the grinding ratio is more than or equal to 1:15, the maximum bendable angle can reach 40 degrees, the tensile strength is greatly improved, the service life is prolonged by two times, the energy consumption is reduced by 5 to 10 percent, and the yield of the finished product can reach more than 99 percent.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a resin bendable grinding wheel, a preparation method and equipment. Background technique [0002] The traditional resin grinding wheel abrasives mostly use brown corundum, white corundum and black silicon carbide materials, so the strength, toughness, grinding efficiency and grinding ratio are not ideal. Not dense enough, making the toughness and safety of the product not high. At present, the domestic resin grinding wheel reinforcement material uses medium-alkali mesh cloth, which has low toughness and strength. Moreover, rubber is generally added to bendable grinding wheels to improve the softness of the product, but at the same time it also sacrifices the anti-aging ability of the product. Caking and sticking often occur in the traditional mixing process, so the looseness and mixing of the molding material are not high; the production of ordinary resin grinding wheels only considers the t...

[0002] The traditional resin grinding wheel abrasives mostly use brown corundum, white corundum and black silicon carbide materials, so the strength, toughness, grinding efficiency and grinding ratio are not ideal. Not dense enough, making the toughness and safety of the product not high

At present, the domestic resin grinding wheel reinforcement material uses medium-alkali mesh cloth, its toughness and strength are not high, and the flexible grinding wheel generally uses rubber to improve the softness of the product, but at the same time it also sacrifices the anti-aging ability of the product

Caking and sticking often occur in the traditional mixing process, so the looseness and mixing of the molding material are not high; the production of ordinary resin grinding wheels only considers the temperature control during the batching process, ignoring the environmental temperature changes between batching and molding. Insufficient bonding stability between abrasive grains, low yield rate of finished products, high curing process temperature in the finished product process, frequent carbonization, and high energy consumption
