Abstract

The invention provides a preparation method of a composite abrasive material, belonging to the technical field of manufacture of abrasive materials. The novel composite abrasive material is characterized by comprising (by weight) 4 to 6 parts of a hard abrasive material, 0.95 to 1 part of a polyurethane elastomeric material and 0.01 to 0.05 part of a fire retardant. The hard abrasive material is uniformly distributed among foams formed by the polyurethane elastomeric material and the fire retardant. The abrasive material provided in the invention can be repeatedly used 8 to 12 times and has working environment dust absorptivity of more than 90% and an abrasive flash point at a temperature of 200 to 300 DEG C. According to the invention, the preparation method comprises the steps of split charging, stirring, maintenance, fragmentation and screening; in the step of fragmentation, a novel horizontal hammerhead crusher or a novel vertical hammerhead crusher installed with a knife type hammerhead is used for fragmentation, which enables the problem that it is difficult to carry out uniform and rapid fragmentation after compounding of the hard abrasive material and soft abrasive materials to be overcome and actual production of the composite abrasive material to be realized.

Description

technical field [0001] The invention relates to a preparation method of a composite abrasive, which belongs to the technical field of abrasive manufacture. Background technique [0002] With the rapid development of ships and the petroleum industry, it is very difficult to clean and maintain the surfaces of shipbuilding, repairs, oil pipelines, tank trucks, drilling platforms and other facilities. It must not only have a certain cleaning efficiency, but also prevent fires caused by sparks. At present, there are mainly two types of hard abrasives and soft abrasives in the domestic and foreign markets. Hard abrasives are easy to break, have large dust, and are prone to sparks, while soft abrasives have small cutting force, low cleaning efficiency, and poor cleaning effect. Therefore, the idea of ​​a composite abrasive came into being. The abrasive is made of polyurethane elastic material and hard abrasive, which not only maintains the cutting force of the hard abrasive, but al...
