The invention discloses a production method of a wear-resistant and yellowing-resistant car cover film, and relates to the technical field of car cover film preparation, the production method of the wear-resistant and yellowing-resistant car cover film comprises the following steps: step 1, preparing raw materials for preparing the car cover film; step 2, preparing a prepolymer; step 3, preparing wear-resistant and yellowing-resistant glue; and step 4, casting the wear-resistant and yellowing-resistant glue into a film, curing to form a wear-resistant layer, and covering the wear-resistant layer with the first release layer. The wear-resistant and yellowing-resistant glue prepared from the polyol, the isocyanate, the chain extender, the wear-resistant filler, the anti-aging agent, the antioxidant and other main raw materials has good flexibility, yellowing resistance and wear resistance; further, the flexibility (the flexibility means that the wear-resistant and yellowing-resistant layer is easy to pull and not easy to tear when the vehicle cover film is pasted), the yellowing resistance and the wear resistance of the wear-resistant and yellowing-resistant layer can be improved, the wear resistance and the yellowing resistance of the vehicle cover film are improved, and the phenomenon that the vehicle cover film is worn or scratched when being scratched is reduced.

    本发明公开了一种耐磨耐黄变的车衣膜生产方法,涉及车衣膜制备技术领域,该耐磨耐黄变的车衣膜生产方法,包括以下步骤:步骤一:准备制备车衣膜的原料;步骤二:制备预聚物;步骤三:制备耐磨耐黄变胶水;步骤四:先将耐磨耐黄变胶水延流成膜并固化形成耐磨层,将第一离型层覆盖在耐磨层面上。本发明通过以多元醇、异氰酸酯、扩链剂、耐磨填料、防老剂和抗氧剂等主要原料制得的耐磨耐黄变胶水具有较好的柔韧性、耐黄变性以及耐磨性,进而能够提高耐磨耐黄变层的柔韧性(柔韧性是指在贴车衣膜时容易拉扯,且不易撕裂)、耐黄变性以及耐磨性,提高车衣膜的耐磨性和耐黄变性,减少车衣膜剐蹭时出现磨损或刮花的现象。
