Polycaprolactone modified fluorosilicone acrylic resin as well as preparation and application thereof

The structural formula of the polycaprolactone modified fluorosilicone acrylic resin is as shown in formula (I): # imgabs0 #: due to the introduction of polycaprolactone soft segment chain segment block copolymerization, the negative influence of a silicon monomer on the flexibility of a paint film is overcome, the flexibility and weather resistance of the paint film are greatly improved, and meanwhile, other comprehensive properties of the paint film are also improved; according to the coating prepared from the polycaprolactone modified fluorosilicone acrylic resin, the polycaprolactone acrylic monomer and the polycaprolactone polyol cooperate with each other, so that the flexibility, the wear resistance, the scratch resistance and the weather resistance of a paint film are further enhanced. 本发明公开一种聚己内酯改性氟硅丙烯酸树脂及其涂料，其结构式如式(Ⅰ)所示：#imgabs0#由于聚己内酯软段链段嵌段共聚的引入，克服了硅单体对漆膜柔韧性的负面影响，极大的提高了漆膜的柔韧性和耐候性，同时还提高了漆膜的其他综合性能；利用聚己内酯改性氟硅丙烯酸树脂制备的涂料，聚己内酯丙烯酸单体与聚己内酯多元醇协同，进一步增强了漆膜的柔韧性、耐磨性、耐刮性，耐候性。
