摘    要:目的研究塑料包装薄膜印刷水性油墨用丙烯酸酯乳液的制备工艺。方法选用可聚合乳化剂,通过种子乳液聚合制备丙烯酸酯乳液,采用傅里叶变换红外光谱仪(FT-IR)、差示扫描量热仪(DSC)对乳液聚合产物进行了表征。结果采用适宜的可聚合乳化剂复配,以及引入单体甲基丙烯酸缩水甘油酯均可提高涂膜的耐水性。改变甲基丙烯酸甲酯、苯乙烯(硬单体)与丙烯酸丁酯(软单体)的比例,可以调整乳液涂膜的耐水性和附着力。结论当乳化剂质量分数为单体量的2.5%,软硬单体质量比为1∶1,甲基丙烯酸缩水甘油酯质量分数为单体量的8%时,所得乳液涂膜以及该乳液配制的油墨在聚酯薄膜上均具有良好的附着力、耐水性。

关 键 词:丙烯酸酯乳液  水性油墨  可聚合乳化剂  单体配比  耐水性  附着力

Abstract:Objective To study the preparation processes of acrylic emulsion used as binder resin of waterborne ink applied on plastic film. Methods The acrylic emulsion was prepared by seed emulsion polymerization technology using polymerisable emulsifiers. The composite emulsion polymer was characterized by Fourier transform infrared ( FTIR) and differential scanning calorimeter( DSC) . Results The water resistance of film was improved when suitable polymerisable emulsifiers were combined in an appropriate way. The water resistance of coating increased with the addition of glycidylsmethacrylate. The water resistance and adhesion of the emulsion coating could be adjusted by changing the ratio of hard monomer ( methyl methacrylate and styrene) to soft monomer ( butyl acrylate) . Conclusion When the content of combined reactive surfactant was 2. 5% of total monomer mass, the mass ratio of soft monomer to hard monomer was 1 : 1, and the content of GMA was 8% , and the emulsion as well as the resulted ink had good adhesion, water resistance of emulsion and ink coating on PET.
Keywords:acrylic emulsion  waterborne ink  polymerisable emulsifiers  ratio of monomers  water resistance  adhesion
