Abstract

The present invention discloses a black carborundum polishing grinding wheel, which is prepared according to the following steps: (1) raw materials are selected according to weight portions: 100 portions of liquid butadiene acrylonitrile rubber, 40 portions of polyvinyl chloride resin, 40 portions of coumarone indene resin or liquid polybenzofuran resin, 5 to 10 portions of di-n-butyl phthalate, 1to 3 portions of barium-cadmium-zinc composite stabilizer, 20 portions of talcum powder, 5 portions of zinc oxide, 3 to 5 portions of azodicarbonamide, 5 portions of sulfur, 0.5 to 1 portions of curing catalyst and 5 portions of carbon soot N-330; (2) the raw materials are poured into a mixer and are uniformly mixed in order to produce slurry, which is then uniformly smeared on the netty plasticsubstrate of grinding wheels needing to be produced, silicon carbide abrasive materials are planted on the netty plastic substrate, after foaming and shaping, the netty plastic substrate is put into an oven to be baked under a temperature between 80 DEG C and 120 DEG C for three to five hours until being totally vulcanized, and after cutting, products with different shapes are produced. In the process of derusting, lacquer removal, deburring, etc. for metal products, the present invention has the advantages of high efficiency, less production of dust, high strength, etc.

Description

Technical field [0001] The invention relates to a grinding wheel, in particular to a black diamond polishing grinding wheel. Background technique [0002] At present, grinding wheels are often used to remove rust, paint, and burrs on the surface or edge of metal products. The grinding wheel inevitably produces dust and debris during the grinding process, which causes different degrees of pollution to the environment, especially to the operator's respiratory tract; and the phenomenon of frequent occurrence of the grinding wheel substrate is a direct threat to people's safety. Summary of the invention [0003] The purpose of the present invention is to provide a black diamond polishing wheel that is safe to use, environmentally friendly, and highly efficient. [0004] In order to achieve the above objectives, the present invention can adopt the following technical solutions: [0005] The black diamond polishing wheel of the present invention is prepared according to the following step...
