Polyurethane composite material as well as preparation method and application thereof

The invention provides a preparation method of a polyurethane composite material, which comprises the following steps: uniformly mixing an isocyanate component, a reactive component, a free radical initiator and a reinforcing material, so that at least one organic isocyanate and active hydrogen are subjected to addition polymerization reaction to obtain a prefabricated molded body; the prefabricated molded body is subjected to curing treatment, so that the at least one acrylate double bond is subjected to a free radical polymerization reaction under the action of the free radical initiator, and the polyurethane composite material is obtained. The problems that in the prior art, polyurethane resin cannot be cut due to the fact that the polyurethane resin is hard and has no shape followability are solved. Meanwhile, the invention also provides a polyurethane composite material and application thereof. 本发明提供了一种聚氨酯复合材料的制备方法，包括将所述异氰酸酯组分、所述反应性组分、所述自由基起始剂和所述增强材料混合均匀以使所述至少一种有机异氰酸酯与所述活性氢发生加成聚合反应，得到预制模制体；将所述预制模制体通过固化处理
