摘　　要：通过对一种JS乳液共聚配方的研究,在乳液反应过程中添加乳化剂和交联单体N-羟甲基丙烯酰胺、有机硅氧烷对JS乳液进行改性,提高了乳液的耐水性能、黏结强度和抗拉强度;调胶时,加入分散剂DA-02,保证水泥粉在乳液中更好地分散。并综合各方面因素对乳液性能的影响,得出了最优配方,即wH-870=0.6%(乳液总量)、wA-17=0.7%(单体总量)、wNMAM=2.0%(单体总量)、wDA-02=2.0%(乳液总量)时,得到JS乳液可以满足聚合物水泥防水涂料的要求。Through the study on a JS emulsion copolymerization formulation, adding emulsifying agent and crosslinking monomer N-methylol aclamide during emulsion polymerization process, by using organosiloxane to modify the emulsion in the reaction process, the emulsion water resistance, adhesive strength and tensile strength were improved. Adding dispersant DA-02 to ensure the cement powder with better dispersion in emulsion during adjust glue process. And the optimal formula was obtained by consideration of comprehensive factors influence on the properties of emulsion, namely W_H-870=0.6% （emulsion volume）, W_A-17 =0.7% （total monomers）, W_NMAM=2% （total monomers）, W_DA-02=2% （total emulsion） JS emulsion ean meet the requirements of polymer cement waterproof paint.
