Abstract

The invention discloses a capacitor plastic shell having excellent noise reduction characteristic, and belongs to the technical field of capacitors; the capacitor plastic shell is specifically prepared from the following materials: polycarbonate, polyvinyl alcohol resin, polyamide resin, modified rice husks, palm oil, a nano rare earth powder, vitrified micro beads, titanium gypsum, isopropanol, polyanionic cellulose, sodium polyacrylate, monoisooctyl diphenyl phosphite, a thickening agent, a defoaming agent, and a dispersing agent. The prepared plastic shell has the advantages of good processing property, high dielectric strength, strong noise reduction characteristic, high temperature resistance and high promotion and use value.

Description

technical field [0001] The invention belongs to the technical field of capacitors, and in particular relates to a plastic case of a capacitor with excellent noise reduction characteristics and a preparation method thereof. Background technique [0002] Most existing power capacitor casings are usually made of stainless steel or ABS engineering plastics. The former shell is bulky, and the cost is high, easy to rust, and it is very easy to cause shell breakdown and fire phenomenon, which is gradually being replaced by ABS material. Although the ABS material shell is light in weight, the wall thickness of the shell made of this material must be more than 5cm, otherwise the deformation resistance temperature is low and it is easy to deform, but when the wall is too thick, the processing difficulty increases and there are many waste products during production. , the pass rate is low, which increases the production cost. At the same time, the ABS material is easy to absorb water,...
