Method for manufacturing resin wheel containing sodium carboxymethylcellulose

Abstract

The invention provides a method for manufacturing a resin wheel containing sodium carboxymethylcellulose. The resin wheel comprises 41%-80% of silicon carbide, 0%-80% of brown fused alumina, 10%-15% of polyimide resin liquid, 11%-15% of 240-mesh phenolic resin powder, 11%-15% of copper-coated iron powder, 0.5%-5% of polytetrafluoroethylene powder, 2%-10% of cryolite packing and 1%-5% of sodium carboxymethylcellulose water solution. The method has the advantages that the sodium carboxymethylcellulose water solution is used as a wetting agent, nanoscale polytetrafluoroethylene powder, fine cryolite, fine phenolic resin powder and other micro powder are evenly suspended in the sodium carboxymethylcellulose water solution and attached to grinding materials, due to the macromolecular structure of the powder, the binding strength of the powder and a binding agent can be improved through intermolecular force, and therefore the strength of the resin wheel is greatly improved. Due to the water-retaining property of sodium carboxymethylcellulose, in the production process, water loss in the production process can be avoided, dust separation is further reduced, and component contents of raw materials are uniform.

Description

technical field [0001] The invention relates to a manufacturing method of a resin grinding wheel sheet containing sodium carboxymethyl cellulose, which belongs to the field of cutting instruments. Background technique [0002] Resin grinding wheel is a grinding wheel made of resin as a binder, such as phenolic resin, epoxy resin, polyurethane resin, etc. The resin grinding wheel has high strength and is mainly used for cutting and grinding metal materials such as steel pipes, steel bars, and steel bars. The production of resin grinding wheels is generally to fully mix liquid resin binders with corundum abrasives of various particle sizes, then add stabilizer fillers, and finally add powdery resin binders to make cohesive abrasives, then use various types of grinding wheels The process requires pressure forming. In resin grinding wheels, the main function of the bond is to hold the abrasive grains and control the wear rate during the grinding process. However, affected by f...

Problems solved by technology

However, affected by factors such as the viscosity of the resin bond and the mixing and stirring equipment, the bond and the abrasive are not mixed uniformly, and it is more difficult to mix with the stabilizer filler uniformly. The composition of the resin grinding wheel after entering the pressure molding process is distributed Unevenness, resulting in the following two results: products with low resin content have large cutting or grinding losses, products with high resin content are easy to burn and burst during cutting, and easily cause the workpiece to turn blue during grinding, making it impossible to perform grinding work

In addition, because both the binder and the filler are in powder form, dust is easily generated during the production process, which seriously pollutes the environment. Therefore, how to improve the uniformity of the mixing material, strengthen the identity of the product, and improve the environment of the mixing workshop are urgent. Can't wait
