High-temperature-resistant halogen-free flame-retarding thermoplastic elastomer and preparation method of high-temperature-resistant halogen-free flame-retarding thermoplastic elastomer

Abstract

The invention discloses a high-temperature-resistant halogen-free flame-retarding thermoplastic elastomer. The high-temperature-resistant halogen-free flame-retarding thermoplastic elastomer is prepared from the following raw materials in parts by weight: 60 to 80 parts of EVA (Ethylene-vinyl Acetate copolymer), 25 to 45 parts of EPDM (Ethylene-Propylene-Diene Monomer), 15 to 35 parts of an ethylene-octene copolymer, 1 to 15 parts of high density polyethylene, 5 to 20 parts of organic modified siloxane, 10 to 30 parts of ammonium polyphosphate, 2 to 5 parts of aluminum hydroxide, 1 to 3 parts of zinc borate, 1 to 5 parts of sulfur, 0.5 to 1.5 parts of an accelerant TMTD (Tetramethylthiuram Disulfide), 0.5 to 2 parts of an accelerant CZ, 0.5 to 2 parts of zinc oxide, 1 to 3 parts of an anti-ageing agent RD, 4 to 18 parts of calcium carbonate, 3 to 5 parts of ground quartz, 5 to 10 parts of an interface compatibilizer, 5 to 20 parts of a plasticizer, 0.5 to 2 parts of an antioxygen, 0.2 to 2 parts of a lubricant and 1 to 3 parts of a processing auxiliary agent. The thermoplastic elastomer disclosed by the invention has excellent high-temperature resistance and flame-retarding performance and has no halogen, low toxin and good comprehensive properties.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomer materials, in particular to a high-temperature-resistant halogen-free flame-retardant thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic elastomer products not only have the excellent properties of high elasticity and aging resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of ordinary plastic processing and wide processing methods, and can be produced by injection molding, extrusion, blow molding and other processing methods , environmentally friendly, non-toxic, and recyclable, which not only simplifies the processing process, but also reduces processing costs. Therefore, thermoplastic elastomer material has become the latest material to replace traditional rubber. It is a more humane and high-grade new synthetic material, and it is also a standard environmental protection material in the ...

Problems solved by technology

As we all know, engineering plastics are expensive and difficult to process, so they cannot be widely used like general-purpose plastics

On the other hand, the flame retardants used in the existing halogen-free thermoplastic elastomers are basically inorganic hydroxides. A large amount of filling not only affects the physical and mechanical properties of the product, but also largely destroys the overall organic structure. , which greatly reduces the thermal aging of the product, and also affects the high temperature resistance of the product
