The invention relates to the technical field of resin compositions, in particular to a thermoplastic polyurethane composite material as well as a preparation method and application thereof. The thermoplastic polyurethane composite material comprises the following raw materials: polyether or diol polyester, a chain extender mixture and a diisocyanate compound, the chain extender mixture is a mixture of surface polarized nonmetal powder and polyol; in the chain extender mixture, the mass percent of the surface polarized nonmetal powder is 0.2-30%. The heat-conducting reinforcing filler is subjected to polarization treatment, so that the heat-conducting uniformity of the composite material is improved. The heat-conducting property of the polyurethane material is improved, and meanwhile, great toughness change and obvious reduction of elongation at break due to too high addition of the filler can be prevented.

    本发明涉及树脂组合物技术领域,尤其涉及一种热塑性聚氨酯复合材料及其制备方法和应用。热塑性聚氨酯复合材料的原料包括:聚醚或二醇聚酯、扩链剂混合物和二异氰酸酯化合物;扩链剂混合物为表面极化的非金属粉末与多元醇的混合物;在扩链剂混合物中,表面极化的非金属粉末的质量百分比含量为0.2~30%。本发明对导热增强填料进行了极性化处理,提高复合材料的导热均匀性。在提高聚氨酯材料导热性能的同时,可以防止由于填料添加过高,发生大幅度的韧性变化,断裂伸长率的明显下降。
