Abstract

The invention discloses a halogen-free flame-retardant thermoplastic elastomer and a preparation method and an application thereof. The halogen-free flame-retardant thermoplastic elastomer comprises the following raw materials in parts by mass: 20-50 parts of polyphenylene ether-polysiloxane copolymers, 10-30 parts of styrene elastomers, 5-20 parts of polyolefin, 1-5 parts of compatilizers, 20-40parts of halogen-free flame retardants, 1-10 parts of triazine carbon forming agents, 5-30 parts of plasticizers, 1-5 parts of lubricants and 0.5-3 parts of antioxidants. At the same time, the invention further discloses the preparation method of the halogen-free flame retardant thermoplastic elastomer and the application of the halogen-free flame retardant thermoplastic elastomer. The thermoplastic elastomer is halogen-free and flame-retardant, the product has low smoke density and good processing performance, and has no problems of precipitation, cracking and the like when placed, and can bewidely applied to sheath materials and plug materials of low-smoke halogen-free flame-retardant power lines, data lines and earphone lines.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic elastomers, in particular to a halogen-free flame-retardant polyphenylene ether-polysiloxane thermoplastic elastomer and its preparation method and application. Background technique [0002] Polyvinyl chloride (hereinafter referred to as PVC) insulation material occupies a dominant position in the wire and cable material industry. After decades of production and use, PVC manufacturing and processing technology has been very mature. Compared with other types of cable insulation materials, not only the cost It is cheap, and the mechanical, physical and electrical properties of the wire itself can be effectively controlled. The most important thing is that PVC has very good flame retardant properties, but because PVC contains a lot of chlorine, it will emit a lot of smoke when burning, which will make people Choking, affecting visibility, causing serious damage to the environment. [0003] Add...
