Abstract

The invention relates to the technical field of chemical materials, in particular to a poly(ether-ester) thermoplastic elastomer and a preparation method thereof. The poly(ether-ester) thermoplastic elastomer is prepared from the following raw materials: dimethyl terephthalate, tetrahydrofuran polyether, tetrabutyl titanate, ethyl orthosilicate, 1,4-butanediol, diethyl phosphite and an antioxidant1010. The poly(ether-ester) thermoplastic elastomer is good in elastic recovery performance and high in the tensile strength and tearing strength.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a polyether ester thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic elastomer, also known as artificial rubber or synthetic rubber. It has the excellent properties of traditional cross-linked vulcanized rubber such as high elasticity, aging resistance and oil resistance, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics. It is the third generation of rubber after natural rubber and synthetic rubber. [0003] Polyester block copolymer elastomer is a material with both rubber and thermoplastic properties, which is widely used in the automotive industry, electronic appliances, sporting goods and other fields. At present, the types of industrialized polyether ester thermoplastic elastomers are relatively single and the overall performance is not good. ...
