Problems solved by technology

[0003] Resin grinding wheel and diamondite grinding wheel are too hard or too hard, and the toughness is not good, so it is easy to wear the surface of the workpiece, so there is a problem of insufficient gloss after polishing. Therefore, the workpiece treated by resin grinding wheel or diamondite grinding wheel needs to be polished A sackcloth wheel and polishing wax are used for gloss modification; while the rubber grinding wheel has the problem of insufficient hardness, which can easily lead to damage to the edge of the handle and insufficient cutting force, resulting in the tool handle not being beautiful and delicate.

Abstract

The invention provides a water-milling environmental-friendly polishing wheel. The polishing wheel comprises, by weight, 30-40 parts of polyether polyol, 10-20 parts of polyester polyol, 20-60 parts of isocyanate, 0.01-0.05 part of catalyst, 1-5 parts of chain extender, 0.1-1.0 part of foaming agent, 100-300 parts of abrasive material, and 5-15 parts of filler. The hardness range of the water-milling environmental-friendly polishing wheel is 92-98A (Shore hardness), compared with a rubber polishing wheel, the water-milling environmental-friendly polishing wheel has the hardness advantage (high hardness, strong grinding force and high grinding efficiency), and compared with a resin grinding wheel and a magnesia grinding wheel, the water-milling environmental-friendly polishing wheel is high in glossiness and good in structural toughness, and workpieces needing to be polished are not easy to be damaged. Therefore, the water-milling polishing wheel can achieve the effects that the surface of the workpiece has good glossiness and beautiful surface texture modification through one-time polishing treatment.

Description

technical field [0001] The invention relates to the technical field of polishing wheels, in particular to a water-milling environment-friendly polishing wheel and a manufacturing method thereof. Background technique [0002] The handles of knives need to be polished and polished. The existing polishing wheels include resin grinding wheels, magnesia grinding wheels and rubber grinding wheels. [0003] Resin grinding wheel and diamondite grinding wheel are too hard or too hard, and the toughness is not good, so it is easy to wear the surface of the workpiece, so there is a problem of insufficient gloss after polishing. Therefore, the workpiece treated by resin grinding wheel or diamondite grinding wheel needs to be polished A sackcloth wheel and polishing wax are used for gloss modification treatment; while the rubber grinding wheel has the problem of insufficient hardness, which easily leads to damage to the edge of the tool handle and insufficient cutting force, resulting in...
