Abstract

The invention relates to the technical field of thermoplastic elastomer material production, and discloses an EPDM / PP thermoplastic elastomer material and an application thereof. The material consists of a component A and a component B, wherein the component A contains EPDM rubber , polypropylene, softener and vulcanizing agent, the component B is DOPO grafted magnesium hydroxide compound halogen-free flame retardant. The present invention can obtain EPDM / PP thermoplastic elastomer material with excellent tensile strength under the premise of using less amount of halogen-free flame retardant, and meanwhile, the EPDM / PP thermoplastic elastomer material of the present invention has better flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of production of thermoplastic elastomer materials, in particular to an EPDM / PP thermoplastic elastomer material and its application. Background technique [0002] EPDM / PP thermoplastic elastomer material is the first type of thermoplastic elastomer to enter the market. It has good physical properties and can be processed by thermoplastic processing equipment and technology. It can be widely used in household appliances, wires and cables, construction, automobiles, etc. industry. As the application range of EPDM / PP thermoplastic elastomer materials continues to expand, EPDM / PPTPV as the "third-generation rubber" gradually replaces traditional rubber, but its application range is limited because of its flammability and large amount of smoke. [0003] At present, there are mainly two types of flame-retardant elastomer materials on the market, one is flame-retardant elastomer materials made of halogen-containi...
