摘　　要：选用4种不同结构的磷酸酯功能单体作为乳化剂合成丙烯酸乳液,分析了单体结构中的PO(环氧丙烷)和EO(环氧乙烷),单酯和双酯以及磷酸含量对丙烯酸乳液合成过程中预乳液稳定性、乳液凝胶率和稳定性的影响。将合成的丙烯酸乳液涂覆于马口铁板上,考察了涂膜的耐水性和耐盐雾性,结果表明:以结构中包含PO、单酯比例高、磷酸含量低的磷酸酯功能单体作为乳化剂,能合成性能优异的丙烯酸乳液,适用于工业漆方向。In this paper,four different structures of phosphate functional monomers were selected as emulsifiers for the synthesis of acrylic emulsions.The effects of PO and EO,mono-and di-ester and phosphoric acid content in the monomer structure on the pre-emulsion stability,gelation rate and stability of emulsion during the synthesis of acrylic emulsions were analyzed.The synthesized acrylic emulsion was coated on tinplate,and the water resistance and salt spray resistance of the coating film were investigated.The results show that a structure with a high proportion of mono-esters and a low phosphoric acid content as an emulsifier can synthesize acrylic emulsion with excellent performance which is suitable for application in the direction of industrial paint.
