Description

Technical field [0001] The invention relates to the technical field of capacitor materials, in particular to a capacitor shell material with polyphenylene ether resin as the main component and a preparation method thereof. Background technique [0002] A capacitor is a device that holds electric charge. Capacitors are one of the most widely used electronic components in electronic equipment. They are widely used in circuits such as DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, and control. According to the different manufacturing materials, it can be divided into: ceramic dielectric capacitors, polyester capacitors, electrolytic capacitors, tantalum capacitors, and advanced polypropylene capacitors. At present, capacitor shells are usually made of ABS engineering plastics. ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance, and electrical properties...

AI Technical Summary

Problems solved by technology

Although the ABS material shell is light in weight, the wall thickness of the shell made of this material must reach a certain level. Otherwise, the side deformation resistance temperature is low and it is easy to deform. Many, the pass rate is low, and the production cost is increased. At the same time, the ABS material is easy to absorb water, resulting in a decrease in the insulation performance of the capacitor case and a decrease in the dielectric strength.
