The invention discloses a green energy-saving wear-resistant cold-resistant flame-retardant thermoplastic rubber and a preparation method thereof, wherein an SIBR/PP/SBS/TPU polymer composite system, an auxiliary material with good wear resistance, loss factor reduction and cold resistance and a halogen-free antimony-free compound flame-retardant system are selected as main components, and the thermoplastic rubber is prepared by preparing an SIBR master batch, a silane modified flame retardant, high-speed mixing preplasticizing, dynamic vulcanization of an internal mixer and an extruder in a combined dynamic vulcanization manner for 2-3 minutes at the conditions of the rotating speed of the internal mixer of 40 revolutions per minute and the temperature of 160-165 ℃, dynamic vulcanization of the extruder and dynamic vulcanization for 5-7 minutes at the conditions of the rotating speed of a screw of 50-70 revolutions per minute and the temperature of 165-180 ℃. The invention has the basic performance of thermoplastic rubber, excellent energy-saving, environment-friendly, flame-retardant and cold-resistant performances, simple process, easy manufacture and low production cost. |
