摘　　要：以可再生资源树脂醇C为部分原料的新型水性醇酸树脂与硅丙乳液共混为基料,加入颜填料和助剂制备了外墙涂料。以耐光老化性能、耐洗刷性能为主要评价标准,优化了配方和工艺。最终确定颜基比为3.5,Si O2加入量为4%,改性醇酸树脂和硅丙乳液配比为10∶21,制备的外墙涂料抗光老化性能可以达到336h,综合性能满足GB/T9744─2014。A new type of water based alkyd resin by renewable resource resin alcohol G as part o~ raw matena~ and silicone acrylate emulsion was blended as base material, to prepare the outer wall coating by adding pigments and fillers. Anti photo aging, wet-abrasion property as the main evaluation criteria to optimize the formulation and process, Finally determine the color base ratio is 3.5, SiO2 to join the amount of 4%, modified alkyd resin and silicone acrylic emulsion ratio of 10：21, the preparation of the external wall coating anti light aging performance can reach 336h, comprehensive performance to meet GB/T9744-2014.
