摘要
以丙烯酸腰果酚酯、丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、丙烯酸(AA)为单体,偶氮二异丁腈(AIBN)为引发剂,通过乳液聚合,合成了腰果酚改性丙烯酸树脂并将其与颜料等混合制备了生物基水性油墨。通过单因素法和正交实验优化树脂配方工艺,利用FTIR、DSC、TG对树脂的结构与性能进行了表征,考察了水性油墨的性能。研究结果表明,树脂最佳制备工艺条件为:反应温度85℃,反应时间6 h,BA的含量为10 mmol,n_(MMA):n_(BA)为1.5:1~2:1,丙烯酸腰果酚酯含量为16 mmol,AA含量为70 mmol,引发剂含量为4 mmol。腰果酚改性丙烯酸树脂具有优异的成膜性,玻璃化转变温度为24.08℃,硬度可达5H,附着力为2级,所制备的水性油墨涂层铅笔硬度为5H,附着力为1级,耐水性等级为4级。
A kind of the biobased cardanol modified acrylic acid resin was prepared from monomer of cardanol acrylate ester,methyl methacrylate(MMA),butyl acrylate(BA)and methacrylic acid(AA)by emulsion polymerization,with azodiisobutyronitrile(AIBN)as initiators,and further mixed with pigments to obtain bio-based water inks.The single factor methods and the orthogonal design methods were used to optimized the formula process.The structure and properties of biobased cardanol modified acrylic acid resin were characterized by FTIR,DSC,TG and the properties of the water-based inks were investigated.The results show that the optimum technological conditions for the synthesis of biobased cardanol modified acrylic acid resin are obtained as follows:reaction temperature of 85℃,reaction time of 6 h,the BA is 10 mmol,n_(MMA):n_(BA)=1.5:1~2:1,the cardanol acrylate ester is 16 mmol,the AA is 70 mmol,the initiator is 4 mmol.The cardanol modified acrylic acid resin has good film forming ability,the glass transition temperature is 24.08℃,the hardness is 5H,the adhesion grade is 2.The hardness of prepared water-based ink coating is 5H,the adhesion grade is 1,and the water resistance grade is 4.
