摘　　要：针对传统醇酸树脂成膜后有刺激性气味、容易产生有机挥发物的问题,本文以邻苯二甲酸酐、己二酸、月桂酸、三羟甲基丙烷、甘油等为原料,二甲苯作为回流溶剂,丙二醇甲醚醋酸酯、碳酸二甲酯为溶剂,采用控制油度、多元酸与多元醇材料配比的方法以制备高固体含量、低黏度的净味环保树脂.将其制成亮光清漆,通过涂层性能的表征,对比分析了不同配比下醇酸树脂的黏度和净味性能,最终获得了一款性能优良、环境友好型的醇酸树脂;很好地解决了传统醇酸树脂高黏度、气味大,耐冲击、附着力和柔韧性差的问题.Addressing the issues of pungent odor and organic volatile compound(VOC)emissions after film formation in conventional alkyd resins,this study aimed to develop a high-solid,low-viscosity,odorless,and environmentally friendly alkyd resin using phthalic anhydride,adipic acid,lauric acid,trimethylolpropane,glycerol,and other raw materials.Xylene was used as the reflux solvent,while propylene glycol methyl ether acetate and dimethyl carbonate were used as solvents.A controlled oil length approach and a meticulous ratio of polybasic acids to polyols were adopted in the synthesis process.The synthesized resin was formulated into a glossy varnish,and its viscosity and odor-reducing properties were evaluated under various formulation ratios through the characterization of coating performance.Ultimately,an alkyd resin with superior performance and environmental friendliness was obtained,effectively resolving the problems associated with traditional alkyd resins,including high viscosity,strong odor,and inferior impact resistance,adhesion,and flexibility.
