Problems solved by technology

However, the existing plastic casing 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, which cannot meet the needs of many occasions.

Abstract

The invention discloses a modified plastic shell for a capacitor. The modified plastic shell is composed of polybutylene terephthalate, ABS plastic, a filling agent, color master batch, dimethyl trimethylsilylmethylphosphonate, polyvinyl chloride resin, a lubricating agent and a modifier. The modifier is composed of, by weight, carboxycellulose, sorbitan trioleate, rosin, sodium hexametaphosphate, alkali lignin, acrylamide, kieselguhr, sodium tripolyphosphate, methyl salicylate, camellia oil and peppermint oil. The prepared capacitor plastic shell is good in mechanical performance and processability, low in cost and melt viscosity and good in shock strength and thermal aging resistance and has excellent heat stability. A small amount of the prepared modifier can achieve the increase function obviously.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a modified plastic case for 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 casing 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, which cannot meet the needs of many occasions. Contents of the invention [0003] The purpose of the present invention is to provide a modified plastic casing for capacitors. [0004] The present invention is realized through the following technical solutions: [0005] A modified plastic shell for capacitors, which is made of the followi...
