Abstract

The invention discloses a high comprehensive performance composite grinding piece which comprises a base material, grinding particles and an adhesion agent, wherein the surface of the base material is divided into a plurality of areas; the grinding particles attached to the identical areas have identical sizes; the grinding particles attached to the different areas have different sizes; the sizes of the grinding particles attached to the various areas of the base material increase gradually from the center of the base material to the edge of the base material; the grinding particles are composite grinding particles formed by compositing nano cerium dioxide particles and silicon dioxide particles; and the adhesion agent consists of a component A and a component B. The invention also provides a manufacturing method of the high comprehensive performance composite grinding piece. The manufacturing method comprises the following steps of a gluing procedure, a sand planting procedure, a post curing procedure, a flexing water carrying procedure, a laser cutting procedure, a base material deformation prevention treatment procedure and a storage procedure. The manufacturing method is simple and convenient, and is low in manufacturing cost, and the manufactured composite grinding piece has weather resistance, fatigue resistance, high temperature resistance and abrasion resistance, and is long in service life and high in polishing efficiency.

Description

technical field [0001] The invention relates to a grinding sheet and a manufacturing method thereof, in particular to a high-comprehensive performance composite grinding sheet and a manufacturing method thereof, which belong to the field of coating moulds. Background technique [0002] Abrasive sheet refers to the use of ultra-precision coating technology to uniformly disperse selected micron or nano-sized grinding powder (diamond, silicon carbide, aluminum oxide, silicon oxide, cerium oxide, etc.) The surface of the substrate is then processed by high-precision cutting technology; the abrasive sheet is used in a wide range of fields, such as the field of optical communications, the field of micro-motors, and the field of hard disks. For example, the steel paper sand disc currently used in the market, the steel paper sand disc is also called a steel paper grinding disc, a high-speed grinding disc, and a grinding disc. Disc coated abrasives. It has high tensile strength and...
