[0005] Chinese patent CN201810105404.1 introduces a preparation method of a high-temperature-resistant high-elasticity halogen-free flame-retardant thermoplastic elastomer, which is to add magnesium hydroxide or aluminum hydroxide to the SBS and SEBS system, and then crosslink through peroxide A high-temperature-resistant high-elastic halogen-free flame-retardant thermoplastic elastomer is obtained, but because it uses an inorganic flame retardant, the flame-retardant effect is relatively poor. Chinese patent CN201210270375.0 introduces a scratch-resistant halogen-free flame-retardant The thermoplastic elastomer composition and its preparation method, in fact, on the basis of the halogen-free flame-retardant thermoplastic elastomer, a scratch-resistant agent is added to realize the final scratch-resistant halogen-free flame-retardant thermoplastic elastomer

Description

technical field [0001] The invention belongs to the field of thermoplastic elastomer preparation, in particular to an antistatic high-efficiency low-smoke halogen-free flame-retardant thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic Elastomer TPE (Thermoplastic Elastomer TPE) is known as the "third-generation synthetic rubber" due to its characteristics of both plastic and rubber. It is widely used in the automotive industry, polymer modification, shoe materials, medicine and other fields. [0003] With the continuous improvement of human awareness of environmental protection, various relevant laws and regulations have been promulgated one after another, making "flame retardant" intensified. Flame-retardant thermoplastic elastomers are shifting from halogen-based products to non-halogenated, low-smoke and low-toxicity. At present, the halogen-free flame retardants on the market are mainly magnesium hydroxide, aluminum hyd...
