Coating with high weatherability and self repairability

一种高耐候性、自修复性涂层

Abstract

The invention provides coating with high weatherability and self repairability. In the invention, monomer optical solidification resin is added into a paint system and is sprayed or brushed to form a film after being dispersed evenly, and the coating with higher weatherability and self repairing performance is obtained. The adding weight of the monomer optical solidification resin is 0.5-5% of that of the basal body resin of the paint system. The invention utilizes the combined action of the ultraviolet light of sunlight and oxygen in air, uses the optical solidification resin to absorb part of the ultraviolet light so as to delay the aging of the coating, utilizes the ultraviolet light causing the aging of the coating as an excitation signal, promotes the optical solidification resin added in the coating to generate an optical solidification reaction on the surface layer of the coating for forming novel coating, prohibits the aging destruction of the coating, enhances the weatherability and realizes the self repairability of the coating.
本发明提供一种高耐候性、自修复性涂层,是将单体光固化树脂添加到涂料体系中,分散均匀后喷涂或刷涂成膜,得到具有较高耐候性和自修复性能的涂层。所述单体光固化树脂的添加重量为涂料体系基体树脂的0.5-5%。本发明利用太阳光的紫外光和空气中氧气的共同作用,以光固化树脂吸收部分紫外光而延缓涂层老化,同时利用导致涂层老化的紫外光作为激发信号,促使涂层中添加的光固化树脂在涂层表层发生光固化反应形成新涂层,阻止涂层的老化破坏,提高耐候性并实现涂层的自修复。
