摘　　要：为了减少普通内墙涂料中所含的VOC、游离甲醛和重金属等有害物质,以游离甲醛含量低的苯丙乳液为基料,通过改性纳米TiO_(2)、颜填料和助剂等制备出符合要求的内墙乳胶漆。在乳胶漆的制备过程中,利用单因素分析和响应面分析方法对乳液用量、苯丙乳液和改性纳米TiO_(2)比和涂覆层数进行优化,寻求最佳工艺配方。结果表明:乳液对涂膜质量影响很大,改性纳米TiO_(2)主要影响涂料的环保性能。内墙乳胶漆的最佳工艺配方为乳液用量为19.5%,苯丙乳液和改性纳米TiO_(2)比为100∶3.90,涂覆层数为2。乳胶漆的各项机械性能和环保性能都符合国家标准。In order to reduce VOC,free formaldehyde,heavy metals and other harmful substances con⁃tained in ordinary interior wall coatings,styrene acrylic lotion with low free formaldehyde content is used as the binder to prepare interior wall latex paint that meets the requirements by modifying nano-TiO_(2),pigments,fillers and additives.In the preparation process of latex paint,single factor analysis and response surface analysis were used to optimize the dosage of lotion,the ratio of styrene acrylic lotion and modified nano-TiO_(2)and the number of coating layers,and seek the best process formula.The re⁃sults show that the emulsion has a great influence on the quality of the coating film,and the modified na⁃no-TiO_(2)mainly affects the environmental protection performance of the coating.The optimal process formula of interior wall latex paint is that the amount of emulsion is 19.5%,the ratio of styrene-acrylic emulsion to modified nano-TiO_(2)is 100∶3.90,and the number of coating layers is 2.The mechanical properties and environmental protection properties of latex paint are in line with national standards.
