Enamelled wire paint for resisting high-frequency pulse

Abstract

The invention discloses enamelled wire paint for resisting high-frequency pulse. The viscosity efflux time of the enamelled wire paint is 20-50 seconds; and the enamelled wire paint consists of the following components in percentage by mass: 9-9.8% of glycol, 15.8-16.82% of dimethyl terephthalate, 13.1-16.9% of trimellitic acid trimethyl, 0.83-0.9% of propylbenzene, 15-16.22% of 1,2,3-trimethylbenzene, 4.1-4.38% of phenol, 14.07-15.27% of 3-methylphenol, 13.96-14.87% of 1,3-dimethyl benzene, 7.4-8.2% of 1,2-dimethyl benzene, 1.9-2.1% of tetrabutyl titanate and 0.95-1.05% of thickening agent. When the enamelled wire paint for resisting high-frequency pulse is coated in the subsequent process, the paint is beneficial to the forming of paint films with even, dense and smooth surfaces; the micropores are greatly reduced; and the anti-scratch performance and the hardness of the paint films are prominently enhanced.

Description

technical field [0001] The invention relates to a wire enamel, in particular to a wire enamel used for resisting high-frequency pulses. Background technique [0002] Enameled wire is an important electrical insulation material, which is prepared by coating polymer insulating varnish on copper, aluminum, manganese-copper alloy and other metal wires according to a specific production process. This specific insulating varnish is enameled wire varnish. The insulating layer (that is, the enameled wire paint film) coated on the enameled wire should have good thermal, electrical, mechanical and chemical resistance properties. Enameled wire is mainly used in electronics, electrical engineering, and electrical equipment, such as motors, household appliances, and electronic instruments. In some specific applications, some enameled wires of special specifications are required, such as walkmans, electronic clocks, micro accumulators, electronic instruments, handheld computers, etc., wh...

However, the uniformity and compactness of the above paint films need to be improved. Therefore, how to develop a paint film that can form a uniform, dense, and smooth surface when coating in subsequent processes, thereby greatly reducing micropores and significantly improving the paint film. The enameled wire enamel with excellent scratch resistance and hardness has become the direction of efforts of ordinary skilled in the art
