采用磷酸酯类乳化剂,通过乳液聚合方式制备了新型水性金属防腐乳胶,研究了乳化剂种类、硬单体比例以及体系玻璃化转变温度的变化对丙烯酸乳胶以及漆膜性能的影响.对制得的乳胶尺寸与分散性进行了表征;研究了漆膜的力学性能及耐腐蚀性等性能.结果表明:使用磷酸酯乳化剂,由于在体系中引入了磷酸根离子,其可与金属离子产生络合作用,能有效提高丙烯酸酯乳胶的耐腐蚀性;同时以苯乙烯作为硬单体主体,设定适当的玻璃化转变温度,可使最终的丙烯酸乳胶体系具有良好的力学性能及耐腐蚀性.
In this paper,a novel acrylic latex for corrosion protection of metals was prepared through emulsion polymerization by using phosphate as the emulsifier.The influential factors on the properties of acrylic latexes and the cured films were investigated,including the type of emulsifiers,ratios of hard monomers and glass transition temperature of acrylic latexes.The properties of latexes were studied by means of particle size analysis.In addition,water absorption test,polarization curve test and mechanical properties test were used to characterize the properties of the cured films.The results showed that the used phosphate emulsifier could complex with metallic ion to improve the corrosion resistance of the acrylic latexes.Meanwhile,the synthesized acrylic latex exhibited good mechanical and anticorrosive properties by using styrene as the main hard monomer with appropriate glass transition temperature.
