Abstract

The invention discloses a high-temperature-resisting resin material composition for a battery case and a preparation method of a high-temperature-resisting resin material. The composition is preparedfrom epoxy acrylate resin, bisphenol F cyanate resin, furan resin, bismaleimide resin, polytetrafluoroethylene, sorbitol, polyphenylene oxide resin and ethylene glycol; relative to 100 weight parts ofthe epoxy acrylate resin, the content of the bisphenol F cyanate resin is 20 to 60 weight parts, the content of the furan resin is 10 to 30 weight parts, the content of the bismaleimide resin is 5 to20 weight parts, the content of the polytetrafluoroethylene is 1 to 10 weight parts, the content of the sorbitol is 10 to 20 weight parts, the content of the polyphenylene oxide resin is 3 to 15 weight parts and the content of the ethylene glycol is 10 to 20 weight parts. The effects of obtaining better high temperature resistance, avoiding deformation at higher temperature and widening the service range of the obtained product are realized.

Description

technical field [0001] The invention relates to the field of new energy batteries, in particular to a high-temperature-resistant resin material composition and a method for preparing the high-temperature-resistant resin material for battery casings. Background technique [0002] With the continuous development of science and technology, the development of new energy batteries is getting faster and faster, and there are more and more new energy battery products on the market, so the development of new energy batteries is very important. New energy batteries are often composed of multiple batteries to form a battery pack. The temperature of the battery pack is high after working for a long time, so the battery pack shell is required to have excellent high temperature resistance and mechanical properties to ensure that the battery is not easily deformed in a high temperature environment. Stability of battery work. [0003] Therefore, to provide a kind of high temperature resis...
