Abstract

The invention relates to a resin grinding wheel and a preparation method thereof, and belongs to the technical field of resin grinding wheel production, and the resin grinding wheel comprises the following raw materials of an abrasive, phenolic resin liquid, phenolic resin powder, cryolite, pyrite, titanium dioxide, floating beads, alkaline earth oxide and a wetting agent. According to the resin grinding wheel, the raw materials are cooperated, under the conditions that the polished surface of a workpiece is glossy and free of black spots, the resin grinding wheel has high workpiece abrasion loss and grinding ratio and low grinding wheel loss, the service life of the resin grinding wheel is prolonged, meanwhile, the resin grinding wheel further has high compressive strength and hardness, and the resin grinding wheel has a good using effect. According to the preparation method of the resin grinding wheel, by adding the annular magnetic field, twice mechanical pressing and twice curing,the raw materials are fully reacted and self-combined, the density and bonding strength of the resin grinding wheel are improved, the resin grinding wheel shows good comprehensive performance, and meanwhile the preparation method has the advantage of being convenient to control.

Description

technical field [0001] The invention relates to the technical field of resin grinding wheel production, more specifically, it relates to a resin grinding wheel and a preparation method thereof. Background technique [0002] Grinding wheel is the main tool for grinding. It is a porous substance composed of abrasives, fillers and binders. It is widely used in metallurgy, construction, railway and other fields. It is mainly used for cutting and polished. At present, in grinding metal with grinding wheels, generally the higher the grinding ratio, the greater the grinding vibration amplitude, the rougher the workpiece grinding surface and poor flatness, and the lower the grinding ratio, the smaller the grinding vibration amplitude, and the smoother the workpiece grinding surface. With the continuous advancement of science and technology, the requirement for the smoothness of the polished surface of the workpiece is increased, and there is an urgent need for a method to improve t...
