摘　　要：为了获得水性油墨用聚丙烯酸酯,采用原位聚合法制备聚丙烯酸酯/二氧化硅复合材料,研究不同二氧化硅含量对复合材料的结构与性能的影响。扫描电子显微镜和差示扫描量热/热重分析结果表明,二氧化硅可均匀地分散于聚丙烯酸酯基体中,且与聚丙烯酸酯有一定相互作用。当二氧化硅质量分数为2%,聚丙烯酸酯/二氧化硅复合材料的综合性能最佳,改性后聚丙烯酸酯硬度由1H提高到3H,附着力由等级1改善至0级,吸水性由34%下降到17.03%,乙醇溶液中的损耗率由51.55%降低至12%。改性后的聚丙烯酸酯可用于制备水性油墨,可广泛运用于对安全级别要求较高的印刷产品,如食品包装印刷产品、药品包装印刷产品和儿童玩具印刷产品等。In order to obtain polyacrylate for preparing water-based ink,polyacrylate/SiO2 composites structure were prepared by in-situ polymerization.The effects of different SiO2 content on the structure and properties of the composites were studied.Testing by SEM and DSC results show that SiO2 dispersed in polyacrylates,and there is force between SiO2 and polyacrylate,it has force between SiO2 and polyacrylate.When the weight content of SiO2 is 2%,combination property is the best.Hardness rises from 1H to 3H,adhesion reduces from classification 1 to classification 0,water resistance reduces from 34%to 17.03%,loss in alcohol drops from 55.15%to 12%.It is used in water-based ink that be used in presswork of food,drug and toy for children that have high requirement on safey.
