Abstract
The invention relates to a low-smoke halogen-free flame-retardant thermoplastic elastomer and a preparation method thereof. The thermoplastic elastomer is prepared from the following raw materials in percentage by weight: 5 to 20 percent of polypropylene, 1 to 5 percent of compatilizer, 10 to 30 percent of SEBS, 20 to 50 percent of filling oil, 8 to 15 percent of magnesium hydroxide, 20 to 30 percent of nitrogen and phosphorus series flame retardant, 1 to 3 percent of PE wax and 0.1 to 0.5 percent of antioxidant. The preparation method for the thermoplastic elastomer comprises the following steps: weighing the raw materials according to the weight ratio; firstly putting the SEBS and white oil into a high mixer and mixing the SEBS and the white oil uniformly, then adding other raw materials into the mixture, mixing the raw materials for 2 to 5 minutes, and discharging the mixed raw materials; and extruding and granulating the uniformly-mixed raw materials in a screw machine. The low-smoke halogen-free flame-retardant thermoplastic elastomer prepared by the method has the characteristic of good flame-retardant effect which can reach grade UL94V0; and the thermoplastic elastomer can be used for extruding sheaths of low-voltage electric wires such as surfaces of data wires, electric wires of chargers and the like.
