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法合成软核硬壳结构的水性纯丙乳液。利
用 ATR-FTIR、TEM、GPC、TG、DMA 表征水性纯丙乳液的结构和性能。结果表明：乳液成膜过程中 DAAM
中的—CO—与 ADH 中的—NHNH 2 发生反应，交联度增加，提高了乳液膜的耐水性、热稳定性、玻璃化转变温
度和油墨在双向拉伸聚丙烯（BOPP）薄膜上的附着力。当 DAAM 用量（以 MMA 和 2-EHA 的总质量为基准，
下同）从 0 增加到 2%，m(ADH)∶m(DAAM)=0.7∶1.0 时，乳液膜的吸水率从 24.2%降到 7.6%，油墨的附着力
从 87%升至 100%；当 m(ADH)∶m(DAAM)从 0∶1 增加到 0.7∶1.0，DAAM 用量为 2%时，乳液膜的吸水率从
28.1%降至 7.6%，油墨的附着力从 0 增至 100%。当 DAAM 用量为 2%，m(ADH)∶m(DAAM)为 0.7∶1.0 时，水
性纯丙乳液可用作环保型水性油墨的连接料。

Abstract: 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) and diacetone acrylamide (DAAM) as monomers, 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 showed that in the process of
emulsion film formation, the —CO— groups in DAAM could react with —NHNH 2 groups in ADH, and
the crosslinking degree increased, which improved the water resistance, thermal stability and glass transition
temperature of emulsion films and the adhesion of ink on biaxially oriented polypropylene (BOPP) film. As
DAAM content (based on the total mass of MMA and 2-EHA, the same below) increased from 0 to 2%,
m(ADH)∶m(DAAM)=0.7∶1.0, the water absorption of emulsion film decreased from 24.2% to 7.6%, and
the adhesion on BOPP film increased from 87% to 100%. While the m(ADH)∶m(DAAM) increased from
0∶1 to 0.7∶1, DAAM content was 2%, the water absorption of emulsion film decreased from 28.1% to 7.6%, and
the adhesion on BOPP film increased from 0 to 100%. The optimal DAAM content and m(ADH)∶m(DAAM)
was 2% and 0.7∶1.0. The emulsion has good potential application in water-based ink for BOPP film.
