The invention relates to the technical field of polyolefin elastomers, in particular to a low-smoke halogen-free flame-retardant ceramizable thermoplastic polyolefin elastomer composite material, a preparation method and application thereof, wherein the low-smoke halogen-free flame-retardant ceramizable thermoplastic polyolefin elastomer composite material comprises the following raw materials in parts by weight: 20-80 parts of thermoplastic polyolefin, 2-10 parts of EVA resin, 2-10 parts of ethylene propylene rubber, 20-70 parts of halogen-free flame retardant, 1-10 parts of smoke suppressant, 20-80 parts of ceramic powder, 0.5-5 parts of compatilizer and 0.02-0.1 part of antioxidant. The thermoplastic polyolefin elastomer composite material has the advantages of excellent flame retardant effect, low smoke density, high strength, good flexibility and high elongation at break; and a compact ceramic product can be formed within the range of 600-1000 ℃, the ceramic forming temperature is low, the ceramic forming is compact, and the formed ceramic product has good high-temperature strength and thermal current impact resistance. |
