一种常温固化氟碳树脂涂料及其制备方法
摘要：
本发明公开了一种常温固化氟碳树脂涂料，按重量百分含量计，该涂料由以下组分组成：三氟氯乙烯-乙烯基酯聚合物38％～60％、偶联剂5％～10％、颜料1％～6％、纳米颗粒1％～5％、助剂0.05％～2％、溶剂20％～45％、固化剂5％～15％、催干剂0.003％～0.05％；所述偶联剂为具有-CF3基团和-CF2基团的氟硅烷；所述助剂为消泡剂和表面活性剂；所述溶剂为二甲苯和甲基异丁基酮或乙酸丁酯和甲基异丁基酮；所述催干剂为二月桂酸二丁基锡。本发明通过采用特定的涂料配方，使氟碳树脂在溶剂中的溶解度增大，且添加的助剂、颜料等易溶，各种组分分散容易，且分散方式多，便于现场进行施工；涂料的附着力可达0级，抗刮伤性很强，抗酸碱盐性能好。
摘要（英）：

The invention discloses a normal temperature curing fluorocarbon resin coating. The coating comprises the following components in percentage by weight: 38 to 60 percent of chlorotrifluoroethylene-vinyl ester polymer, 5 to 10 percent of coupling agent, 1 to 6 percent of pigment, 1 to 5 percent of nanoparticles, 0.05 to 2 percent of aid, 20 to 45 percent of solvent, 5 to 15 percent of curing agent and 0.003 to 0.05 percent of drier, wherein the coupling agent is fluorosilane with -CF3 and -CF2 groups; the aid is a defoamer or a surfactant; the solvent is xylene and methyl isobutyl ketone or butyl acetate and the methyl isobutyl ketone; and the drier is dibutyltin dilaurate. By adopting a specific coating formula, the solubility of fluorocarbon resin in the solvent is improved, the added aid, pigment and the like are soluble, various components are easy to disperse in various dispersion modes, the coating is convenient to operate on site, the adhesion of the coating can reach level 0 and the coating has high scratch resistance and high acid, alkali and salt resistance.
