摘　　要：以水性丙烯酸改性醇酸树脂W-02和水性丙烯酸乳液812A为成膜物质,选择合适的助剂制备出一种快干水性钢结构防腐蚀涂料。研究了成膜物的选择、助溶剂的种类及用量、水性丙烯酸改性醇酸树脂及水性丙烯酸乳液的用量对涂料性能的影响。结果表明,以丙二醇甲醚作为体系的助溶剂,用量为涂料总量的5%,m(W-02)∶m(812A)=3∶5时,涂料表干时间为15 min,实干时间为6 h,涂膜60°光泽90,附着力1级,硬度H,耐水时间168 h,耐中性盐雾240 h。Waterborne acrylic modified alkyd resin W-02 and waterborne acrylic emulsion 812A were used as film-forming materials,and a quick drying waterborne steel anticorrosive coating was prepared by selecting suitable additives.The effects of the choice of film forming material,the type and amount of cosolvent,the dosage of waterborne acrylic modified alkyd resin and waterborne acrylic emulsion on the properties of the coatings were studied.The results showed that the water-borne acrylic modified alkyd resin and waterborne acrylic emulsion were combined to form the film forming material.Propylene glycol ether was used as the cosolvent of the system.The dosage was 5%of the total coating.When the m(W-02)∶m(812A)=180∶300,the coating dry time was 15 min,and the dry time was 6 h,the coating 60 degree gloss 90,the adhesion force 1 level,the hardness H,168 h of water resistance and 240 h of neutral salt spray resistance.
