摘要： 使用非食用花椒籽油（ZSO）、三羟甲基丙烷（TMP）、废弃PET瓶、邻苯二酸酐（PA）和水性单体2，2-二羟甲基丙酸（DMPA），通过醇解、酯化、中和三步反应制备了一种绿色环保型水性醇酸树脂。探讨了油度、醇超量、酸值和PET解聚物对漆膜性能的影响，并采用FT-IR、TGA和粒径分析对水性醇酸树脂的结构以及热稳定性进行了测试表征。实验结果表明，油度为50%、醇超量为11.5%、10%的DMPA为亲水单体合成的醇酸树脂，使用9.3%的PET解聚产物对其进行改性使其耐水性、热稳定性和硬度得到提高，产品稳定性良好。

Abstract: Waterborne alkyd resins were synthesized from non-edible zanthoxylum bungeanum seed oil（ZSO），trimethylolpropane（TMP），postconsumer PET bottles，phthalic anhydride（PA）and 2，2-bis（hydroxymethyl）propionic acid（DMPA）via three stages including alcoholysis，polyesterification and neutralization reaction. The effects of oil length，the excess of alcohol and acid value on the properties of PET-modified alkyd resins were investigated. The structure and properties of the prepared polymer were characterized by FT-IR，QLS and TGA. Experimental results indicate that the alkyd resin prepared from DMPA as hydrophilic monomer with an oil length 50% and an excessive hydroxyl 11.5% and 10% followed by modification with PET glycolysis 9.3% exhibits good water resistance，hardness，thermal stability and environmental friendly performance.

Key words: zanthoxylum bungeanum seed oil, alkyd resin, PET bottles, glycolysis
