以桐亚油酸、亚油酸、季戊四醇、新戊二醇、间苯二甲酸、苯甲酸、顺丁烯二酸酐等为原料合成基础醇酸树脂,并将苯乙烯、丙烯酸类单体、有机硅单体等混合后接枝到基础醇酸树脂分子中,制备了一种水性涂料用高光自干型水性丙烯酸改性醇酸树脂。利用红外光谱(FT-IR)、核磁共振波谱(1H NMR)、Zeta电位纳米粒度分析仪、接触角测量仪表征了树脂的分子结构以及其乳液的粒径、接触角,并根据相关国家标准对漆膜性能进行表征。结果表明:该水性醇酸树脂具有光泽度高、常温自干、耐水性强、附着力优异等特点,可用来制备高光自干型水性醇酸防腐涂料。

In this paper,the basic alkyd resin is synthesized from linoleic acid,linoleic acid,pentaerythritol,neopentyl glycol,isophthalic acid,benzoic acid,maleic anhydride,etc.Styrene,acrylic and silicone monomers are mixed,and grafted into the base alkyd resin molecule to prepare a high-light selfdrying waterborne acrylic modified alkyd resin for aqueous coatings.The molecular structure of the resin,the particle size and contact angle of the emulsion were characterized by infrared spectroscopy(FT-IR),nuclear magnetic resonance spectroscopy(^1H NMR),Zeta potential nano-particle size analyzer and contact angle measuring instrument.According to the relevant national standards,the coating film properties were systematically characterized.The results show that the waterborne alkyd resin has the characteristics of high gloss,self-drying at room temperature,strong water resistance and excellent adhesion,and can be used for preparing high-light self-dry ing waterborne alkyd anticorrosive coating.
