Abstract
The invention discloses a flame-retardant thermoplastic elastomer and a preparation method thereof. The flame-retardant thermoplastic elastomer is prepared from the following raw materials in parts by weight: 80-120 parts of SEBS (styrene-ethylene-butadiene-styrene), 5-10 parts of color master batch, 1-2 parts of composite anti-photoaging agent, 2-6 parts of flame retardant APP (ammonium polyphosphate), 3-5 parts of silica white and 3-6 parts of chitin. The preparation method comprises the following steps: (1) proportioning: proportioning according to parts by weight; (2) feeding: putting the (styrene-ethylene-butadiene-styrene) into a stirrer, adding the flame retardant APP, silica white and chitin, sufficiently stirring, adding the other raw materials, and stirring to obtain a mixture; (3) heating and extrusion: adding the mixture into an extruder to perform extrusion, wherein the temperatures of the head, transition section and port mold of the extruder during extrusion are respectively controlled at 110-130 DEG C, 150-160 DEG C and 180-190 DEG C; (4) cooling and cutting; and (5) drying, packaging and warehousing. The flame-retardant thermoplastic elastomer has the characteristics of high flame retardancy, high aging resistance, favorable toughness, high oxidation resistance and the like, and still has favorable elasticity without softening at high temperature.
