一种基于氟硅改性丙烯酸树脂的防腐涂料及其制备
摘要：
本发明公开了一种基于氟硅改性丙烯酸树脂的防腐涂料，所述该涂料的组成及重量百分含量为：氟硅改性丙烯酸树脂为30‑50％，鳞片状锌粉为10‑45％，鳞片状云母片为10‑30％，磷铁粉为5‑10％，聚氨酯聚醚嵌段共聚物为0.5‑2％，乙酸丁酯为10‑15％组成，以上各组份的重量百分含量之和为100％；其中，所述的氟硅改性丙烯酸树脂由氟硅改性丙烯酸酯与丙烯酸酯按照摩尔比1：2‑5在偶氮类引发剂的作用下聚合而成，所述氟硅改性丙烯酸酯是由全氟烷基乙基醇、芳香族二异氰酸酯、聚二甲基硅氧烷和丙烯酸酯按照摩尔比1：1‑1.2：1‑1.2：2‑5反应而成。该涂料通过设计新型氟硅改性丙烯酸树脂，使氟硅基团在高分子中分布均匀，氟硅改性丙烯酸树脂防腐涂料达到性能稳定的效果。
摘要（英）：

The invention discloses an anticorrosive coating based on fluorine-silicon modified acrylic resin. The coating contains the following components in percentage by weight (100% in all): 30%-50% of fluorine-silicon modified acrylic resin, 10%-45% of flaky zinc powder, 10%-30% of flaky mica plates, 5%-10% of ferrophosphorus powder, 0.5%-2% of a polyurethane-polyether block copolymer and 10%-15% of butyl acetate, wherein the fluorine-silicon modified acrylic resin is prepared by polymerizing fluorine-silicon acrylate with acrylate in a molar ratio of 1 to (2-5) under the action of azo initiators, and the fluorine-silicon modified acrylate is prepared through reaction of perfluoroalkyl ethyl alcohol, aromatic diisocyanate, polydimethylsiloxane and acrylate in a molar ratio of 1 to 1 (1-1.2) to (1-1.2) to (2-5). By designing the novel fluorine-silicon modified acrylic resin, fluorine-silicon groups are uniformly distributed in macromolecules, and the fluorine-silicon modified acrylic resin anticorrosive coating has the effect of stable performance.
