Problems solved by technology

Traditional grinding discs have defects such as complex production process, low matrix strength, high cost, unstable safety performance, poor moisture-proof or water-resistant performance, and are not suitable for outdoor operations and operations with water, and often cause grinding due to low strength. Fragments are broken and fly out to cause safety accidents that hurt people, and the substrate processed with cotton pulp and pulp seriously consumes natural resources

Abstract

The invention relates to a grinding tool. The powerful grinding sand disk is characterized by comprising a substrate, a reinforcing ring and a grinding work layer; the middle of the substrate is provided with a through hole; the reinforcing ring is fixed on the through hole of the substrate; the front side of the substrate is provided with the annular grinding work layer; the reinforcing ring is positioned on the inner side of the grinding work layer; and the material of the substrate comprises glass fibre or polyester cotton. The powerful grinding sand disk has the characteristics of high strength, good water resistance and weather fastness, low production cost and strong grinding force and is simple to manufacture.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a grinding sand disc grinding tool. Background technique [0002] At present, the traditional grinding sand disc in China is made of cotton pulp or wood pulp through processing to make a paper substrate of the sand disc (that is, a red steel paper substrate), and then coat a layer of primer on the red steel paper substrate and then plant sand. After preliminary drying, curing and shaping, a layer of glue and a layer of sand are applied, and a grinding sand disc is made after drying, shaping and curing of the glue. This kind of grinding disc is mainly used for grinding and polishing of various metals (such as shipyard hulls) in China, such as rust removal and burring, and can also be used for grinding and polishing of cement floors. Traditional grinding discs have defects such as complex production process, low matrix strength, high cost, unstable safety performance, poor moisture-proof or wate...
