摘要

将甲基丙酰氧乙基磷酸酯(P单体)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)及丙烯酸(AA)采用半连续乳液聚合,制备磷酸酯共聚改性丙烯酸酯乳液,并配制乳胶涂料。研究了P单体用量、引发剂用量、乳化剂配合比等对乳液及乳胶涂料性能的影响。研究结果表明:磷酸酯的引入,会形成一种磷化膜减缓燃烧,从而起到阻燃作用;当P单体用量为2.2%(wt,质量分数)、引发剂过硫酸钾(KPS)用量为0.13%(wt,质量分数)、十二烷基硫酸钠(SDS)与乳化剂OP-10质量配合比为3∶1制得的磷酸酯共聚改性丙烯酸酯乳胶涂料的附着力为1级、湿附着力为1级、耐水性达到480h无泡和无锈、耐盐水性达到120h无泡和无锈,具有较好的耐腐蚀性能。

Abstract

Phosphate modified acrylate emulsion was synthesized via semi-continuous emulsion polymerization used methyl acrylic ethoxy phosphate (P monomer),methyl methacrylate (MMA),butyl acrylate (BA) and acrylic acid (AA) as monomers.Moreover,latex coating was also prepared.The effects of P monomer,initiator,emulsifier ratio and other factors on the properties of emulsion and coating were studied.The results showed that the introduction of phosphate formed phosphide film to slow down the combustion,thus playing a role in flame retardant.When the dosage of P monomer and initiator were 2.2(wt)%,0.13(wt)%,and,the ratio of SDS∶OP-10 was 3∶1,the latex coating exhibited good corrosion resistance:1 grade adhesion,1 grade wet adhesion,480h water resistance,and 120h salt water resistance.
