High-performance composite backing plate preparation method

Abstract

The invention belongs to the technical field of composite backing plate preparation, and discloses a high-performance composite backing plate preparation method. The high-performance composite backingplate preparation method comprises the following steps that a base plate is cut and segmented, and surface treatment is carried out on a coating surface of the base plate; high-hardness polymer resinis prepared and molten, and the base plate is coated with the high-hardness polymer resin through a roller coater; the base plate coated with the high-hardness polymer resin is put into an annealingfurnace for high-temperature curing; protective gas is continuously pumped in the curing process; and the base plate of the high-hardness polymer resin is cut, polished and ground. According to the high-performance composite backing plate preparation method, the size meeting the standard can be designed as required; surface treatment is carried out on the designed base plate, so that the situationthat the quality of the high-performance composite backing plate is affected due to the fact that impurities appear on the surface of the polymer resin in the roller coating process is prevented; andthe roller coater is used for coating the high-hardness polymer resin on the base plate, and in the coating process, the high-hardness polymer resin is baked according to a certain time interval, sothat the bonding quality of the polymer resin and the base plate is improved.

Description

technical field [0001] The invention belongs to the technical field of composite pad preparation, and in particular relates to a preparation method of a high-performance composite pad. Background technique [0002] At present, polymer resin is also called polyaddition resin. Resin synthesized by polymerization (addition polymerization) reaction. Formed from molecules containing double or triple bonds or bifunctional molecules formed by ring opening of cyclic molecules. Generally, it is a linear polymer with thermoplasticity. Polymerized from a monomer called homogeneously polymerized resin (homogeneously polymerized resin), such as polyethylene, polystyrene, polypropylene, polyvinyl chloride, polyvinyl acetate and polyacrylonitrile. In order to improve the quality of the backing plate, a layer of polymeric resin needs to be roll-coated on the substrate. At the same time, the roller coating uses the roller as the carrier of the paint. The paint forms a wet film of a certa...

Problems solved by technology

However, after the preparation of the high-performance composite backing plate in the prior art is completed, the polymer resin is easy to separate from the substrate; in the prior art, impurities appear on the surface during the roller coating process of the polymer resin, which affects the quality of the high-performance composite backing plate

[0003] Through the above analysis, the existing problems and defects of the prior art are: after the preparation of the high-performance composite backing plate in the prior art, the polymer resin is easy to separate from the substrate; The quality of the backing plate
