Abstract

The invention discloses a high-temperature-resistant degradable shell for a capacitor and a preparing method of the high-temperature-resistant degradable shell. The high-temperature-resistant degradable shell is prepared from, by weight, 26-30 parts of polyacrylic resin, 22-24 parts of starch, 20-22 parts of straw powder, 16-18 parts of linear polyethylene, 14-16 parts of cellulose acetate fiber,12-14 parts of mica powder, 10-14 parts of ferric oxide powder, 8-10 parts of talcum powder, 6-8 parts of photosensitizer, 3-6 parts of plasticizer, 2-5 parts of coupling reagent, 2-4 parts of dispersant, 1-3 parts of antioxidant, 1-3 parts of heat stabilizer and 1-2 parts of hydrolase. The high-temperature-resistant degradable shell has high high-temperature resistance and shock resistance, besides, the material cost is low, the materials are easy to obtain, the using value is high, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of capacitor materials, in particular to a high-temperature-resistant and easily degradable casing for capacitors and a preparation method thereof. Background technique [0002] A capacitor is composed of a layer of insulating dielectric sandwiched between two metal electrodes. When a voltage is applied between the two metals, the capacitor will store charge, so the capacitor is an energy storage element. According to the different manufacturing materials, the capacitor is divided into: ceramic capacitor , electrolytic capacitors, polyester capacitors, etc. With the rapid development of the electronics industry, the requirements for high-level, low-price electronic products are becoming more and more urgent. Capacitors are the basic electronic products, so the requirements for capacitors are getting higher and higher.

Problems solved by technology

[0003] In the prior art, the capacitor casing is made of ABS plastic through an injection molding machine, which has poor heat resistance and will be deformed above 100°C. In addition, the wall thickness of the produced product must reach a certain level to resist deformation, which increases the difficulty of production. The increase in waste products during production increases the cost. At the same time, the materials are difficult to degrade, causing environmental pollution and failing to meet environmental protection requirements.
