Problems solved by technology

[0003] The thermoplastic elastomer materials currently produced have insufficient high temperature resistance in some special fields (such as sealing rings). After the thermal aging test at 135°C×1000h, the material will often fail in performance and the aging speed will be accelerated. Therefore, it can only be used in If it is used in a short period of time, it needs to be replaced frequently, which has a great impact on production efficiency, and the material may fail at any time, causing safety hazards

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a high temperature and aging resistant thermoplastic elastomer material and a preparation method thereof. Background technique [0002] Thermoplastic elastomer TPE / TPR, also known as artificial rubber or synthetic rubber, is a new type of polymer material between rubber and resin. It can not only replace part of rubber, but also modify plastic. Thermoplastic elastomer has rubber It has the dual properties and broad characteristics of plastics. It not only has the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, but also has the characteristics of more convenient processing and wide processing methods of ordinary plastics. Therefore, thermoplastic elastomers TPE / TPR material has become the latest material to replace traditional rubber. [0003] The thermoplastic elastomer materials current...
