The invention belongs to the field of coating preparation, and particularly relates to a high-weather-resistance repairable coating as well as a preparation method and application thereof. According to the invention, polyol and isocyanate are subjected to a cross-linking reaction to form a coating film. When the coating is applied to the car cover market, the coating must be soft and convenient to attach, while the car cover belongs to an outdoor product and has high requirements on weather resistance, and the coating is hard due to high crosslinking density of the required coating. The softness and the hardness need to exist at the same time, but are contradictory to each other. According to the invention, a nano-scale high-stain-resistant coating is adopted, so that a soft and hard coating film is obtained.
本发明属于涂层制备领域,具体涉及一种高耐候可修复涂层及其制备方法和应用。本发明采用多元醇与异氰酸酯发生交联反应,形成涂膜。应用于车衣市场,涂膜必须柔软便于贴附,而车衣属于户外产品,对于耐候有着较高的要求,需要涂膜的交联密度高,会导致涂膜偏硬。柔软和硬需要同时存在,但又是相互矛盾的。本发明采用纳米级高耐污涂层,得到“又软又硬”的涂膜。
