Problems solved by technology

However, the existing plastic shell materials for capacitors have poor stability to light and heat. After long-term electromagnetic radiation, the physical and mechanical properties will also decline rapidly, and the brittleness and impact resistance will deteriorate. Moreover, the existing plastic shells for capacitors The flame retardancy of the material is not high, which cannot meet the needs of many occasions

Abstract

A high-performance capacitor plastic housing is disclosed. The plastic housing is prepared from polybutylene terephthalate, ABS plastic, a filler, a color concentrate, dibutyl sebacate, polyamide, a lubricant and an auxiliary agent. The auxiliary agent is prepared from, by weight, carboxyl cellulose, sorbitan trioleate, rosin, sodium hexametaphosphate, alkali lignin, acrylamide, diatomite, sodium tripolyphosphate, methyl salicylate, tea seed oil and mint oil. The plastic housing has characteristics of good mechanical properties, good processing performance, a low cost, a low melt viscosity, high impact strength, good thermal aging resistance and excellent thermal stability.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a plastic casing for high-performance capacitors. Background technique [0002] Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. However, the existing plastic shell materials for capacitors have poor stability to light and heat. After long-term electromagnetic radiation, the physical and mechanical properties will also decline rapidly, and the brittleness and impact resistance will deteriorate. Moreover, the existing plastic shells for capacitors The flame retardancy of the material is not high, which cannot meet the needs of many occasions. Contents of the invention [0003] The object of the present invention is to provide a plastic casing for high-performance capacitors. [0004] The present invention is realized th...
