摘　　要：通过对一种醋丙型防水乳液共聚配方的研究,在乳液反应过程中添加AP-02保护胶和交联单体N-羟甲基丙烯酰胺、A171有机硅氧烷、丙烯酸-2-羟丙酯对醋丙乳液进行改性,提高了乳液的耐水性能、粘结强度和抗拉强度;调胶时,加入分散剂DA-02,保证水泥粉在乳液中更好地的分散。并综合各方面因素对乳液性能的影响,得出了最优配方,即w(AP-02)=1.2%(乳液总量)、w(A-171)=0.7%(单体总量)、w(NMAM)=2.0%(单体总量)、w(DA-02)=2.0%(乳液总量)时,得到醋丙型乳液可以满足聚合物水泥防水涂料的要求。By analyzing a vinyl acetate-acrylate waterproof emulsion copolymerization formula, in the emulsion reaction process, the AP-02 protective colloid and a erosslinking monomer N- hydroxymethyl aerylamide, A171 silicone, acrylic -2- hydroxypropyl ester was added in order to modify the vinyl acetate-acrylate emulsion, The water resistance, bonding strength and ultimate tensile strength was improved. The DA-02 dlspersant was added in the process of adjusting adhesive to guarantee a better dispersion of cement powders in the emulsion. And in the consider of various factors which had effects on the emulsion performance, the best formula was obtained as follows： w（AP-02）=1.2% （total emulsion amounts）, w（A-171）= 0.7% （total monomers amounts）, w（NMAM）=2.0%（total monomers amounts） and w（DA-02）=2.0%（total emulsion amounts）. The vinyl acetate-acrylate copolymerization emulsion could meet the polymer cement waterproof coating requirements
