Problems solved by technology

[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

Embodiment

[0022] a. Mix 60 kg of brown corundum, 10 kg of calcined corundum, 20 kg of white corundum and 10 kg of black silicon carbide, put them into a small mixing pot 1, then add 6 kg of phenolic resin solution, and stir evenly with a small stirrer 5 , then add 6 kg of cryolite, 2 kg of barium sulfate, 5 kg of pyrite, and 2 kg of red iron oxide and stir evenly with a small agitator 5. After the mixed material is fully wet, open the valve 4 to mix the mixed material Put it into the large mixing pot 2 through the feeding chute 3, then add 18 kg of phenolic resin powder in the large mixing pot 2 and stir with the large agitator 6 until every grain of sand is evenly wrapped by the phenolic resin powder, and then put its into the bin;

[0023] b. Put the material box in the preheating constant temperature room for 3 hours, then take out the mixed material, beat loose, and sieve it into sand material, put the sieved sand material into the spreader, and carry out the first spread material,...

Abstract

The invention discloses a resin bendable grinding wheel, a preparation method and equipment, which are composed of brown corundum, calcined corundum, white corundum, black silicon carbide, phenolic resin powder, phenolic resin liquid, cryolite, barium sulfate, pyrite, oxidized Iron red, sea glue, non-alkali high tensile glass fiber mesh, non-woven black cloth. Compared with the prior art, the present invention greatly improves the strength, toughness and aging resistance of the grinding wheel through material selection and optimized configuration of the process, and also saves resources and energy consumption; the strength of the grinding wheel is greater than 80m / s , Grinding ratio ≥ 1:15, maximum bending angle of 40°, greatly improved tensile strength, extended damage life by about two times, reduced energy consumption by 5%-10%, and finished product yield of more than 99%.

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...
