The invention relates to the technical field of TPU materials, and particularly discloses a wear-resistant
flame-retardant TPU material and a preparation method thereof. The TPU material is prepared from the following raw materials in parts by weight: 60 to 100 parts of
polyurethane, 15 to 30 parts of
epoxy resin, 3 to 10 parts of di-o-chlorodiphenylamine
methane, 20 to 50 parts of
polyethylene, 10 to 28 parts of modified
calcium sulfate dihydrate
whisker, 10 to 28 parts of composite
flame retardant and 2 to 6 parts of
silicone oil. The preparation method comprises the following steps: uniformly mixing the
silicone oil and the modified
calcium sulfate dihydrate
whisker to obtain a mixture A; uniformly mixing
polyurethane,
epoxy resin, di-o-chlorodiphenylamine
methane and
polyethylene to obtain a mixture B; then adding the composite
flame retardant into the mixture B, and uniformly stirring to obtain a mixture C; finally, uniformly mixing the mixture A and the mixture C to prepare the wear-resistant and flame-retardant TPU material. The wear-resistant flame-retardant TPU material disclosed by the invention has the advantages of
high wear resistance and high flame retardance.
