中文摘要:
      以甲基丙烯酸甲酯(MMA)、丙烯酸异辛酯(2-EHA)、甲基丙烯酸(MAA)、双丙酮丙烯酰胺(DAAM)为聚合单体,己二酰肼(ADH)为交联剂,采用半连续种子乳液聚合方法合成软核硬壳结构的水性聚丙烯酸酯乳液。利用ATR-FTIR、TEM、GPC、TG、DMA等表征水性聚丙烯酸酯的结构和性能。结果表明:乳液成膜过程中DAAM中的-CO-基团与ADH中的-NHNH2基团发生反应,交联度增加,提高乳液膜的耐水性和乳液在双向拉伸聚丙烯(BOPP)薄膜上的附着力。与未交联体系相比,交联体系提高乳液膜的热稳定性和玻璃化转变温度。当DAAM含量从0%增加到2%,乳液膜的吸水率从24.2%减小到7.6%,乳液的附着力从 87%升至100%;当m(ADH)/m(DAAM)从0:1增加到0.7:1,乳液膜的吸水率从28.1%降至7.6%,附着力从0%增至100%,故本实验中最佳DAAM含量为2%,m(ADH)/m(DAAM)为0.7:1,可用作环保型水性油墨的连接料。
英文摘要:
      The waterborne polyacrylate emulsions with soft core-hard shell structure were synthesized by semi-continuous emulsion polymerization technology using methyl methacrylate (MMA), 2-ethylhexyl acrylate (2-EHA), methylacrylic acid (MAA), diacetone acrylamide (DAAM) as monomers, and adipic dihydrazide (ADH) as crosslinker. ATR-FTIR, TEM, GPC, TG and DMA were utilized to characterize the bulk structures and properties of waterborne polyacrylate. The results show that crosslinking reaction between -CO-groups of DAAM and -NHNH2 groups of ADH can occur during emulsion film formation. The water resistance of emulsion film and the adhesion ratio of emulsion on biaxially oriented polypropylene (BOPP) film were improved due to the increased crosslinking density. Compared with the without crosslinked film, the crosslinked film improves thermal stability and glass transition temperature of the emulsion film. As DAAM content increased from 0% to 2%, water absorption ratio of emulsion film decreased from 24.2% to 7.6%, adhesion ratio on BOPP film increased from 87% to 100%. While the m(ADH)/m(DAAM) ratio increased from 0:1 to 0.7:1, water absorption ratio of emulsion film decreased from 28.1% to 7.6%, adhesion ratio on BOPP film increased from 0% to 100%. The optimal DAAM content and m(ADH)/m(DAAM) ratio was 2% and 0.7:1. The emulsion has good potential application in water-based ink for BOPP film.
