本发明涉及一种热塑性聚氨弹性体膜、其制备方法及其在制备车衣膜时的应用。上述热塑性弹性体膜的制备方法包括以下步骤:加热热塑性聚氨酯弹性体原胶,并将所述热塑性聚氨酯弹性体原胶涂布在在第一离型膜的表面上;将第二离型膜覆盖于所述热塑性聚氨酯弹性体原胶的表面,得到复合膜,其中所述热塑性聚氨酯弹性体原胶位于所述第一离型膜与所述第二离型膜之间;采用紫外线照射所述第一离型膜的表面和所述第二离型膜的表面,使所述热塑性聚氨酯弹性体原胶固化;去除离型膜,得到热塑性聚氨酯弹性体原胶膜;将所述热塑性聚氨酯弹性体原胶膜放入烘箱,烘烤后冷却,得到所述热塑性聚氨弹性体膜。

    The present application relates to a thermoplastic polyurethane elastomer film, a preparation method therefor and use thereof in preparing a vehicle paint protection film. The method for preparing a thermoplastic polyurethane elastomer film comprises: heating a thermoplastic polyurethane elastomer raw gum, and coating the thermoplastic polyurethane elastomer raw gum on a surface of a first release film; covering a second release film on the surface of the thermoplastic polyurethane elastomer raw gum to obtain a composite film; using ultraviolet rays to cure the thermoplastic polyurethane elastomer raw gum; removing the release film to obtain a thermoplastic polyurethane elastomer raw gum film; and baking and cooling the thermoplastic polyurethane elastomer raw gum film.
