摘要：以丙烯酸丁酯（BA）、甲基丙烯酸甲酯（MMA）、丙烯酸羟乙酯（HEA）为主要单体，桐油酸和甲基
丙烯酸缩水甘油酯（GMA）为功能性单体，采用半连续乳液聚合法制备了一系列桐油酸改性含环氧基团聚丙烯
酸酯乳液（简称改性聚丙烯酸酯乳液）。通过 FTIR 表征胶膜的结构，测定了胶膜的耐水性能、力学性能、热稳
定性、耐酸碱性。结果表明，当桐油酸含量（以 MMA、BA、HEA、GMA 的总质量为基准）为 4%时，随着
GMA 含量（即 GMA 质量占总丙烯酸酯单体质量的百分数，下同）的增加，胶膜铅笔硬度增大，耐水、耐酸碱
性能增强，拉伸强度增大，热稳定性增加，胶膜附着力增加。当 GMA 含量为 12%时，胶膜铅笔硬度为 4H，涂
在马口铁上的胶膜在质量分数为 5%的盐酸溶液中浸泡 144 h 无变化，在质量分数为 5%的 NaOH 水溶液浸泡 72
h 无变化，24 h 的吸水率为 3.31%，附着力为 0 级。

Abstract: A series of tung oleic acid modified polyacrylate emulsions containing epoxy group (modified
polyacrylate emulsion for short) were prepared by semi-continuous emulsion polymerization of butyl
acrylate (BA), methyl methacrylate (MMA), hydroxyethyl acrylate (HEA) with tung oil acid and glyceride
methacrylate (GMA) respectively, and characterized by FTIR. The water resistance, mechanical properties,
thermal stability, as well as the acid and alkali resistance were further analyzed. The results showed that
when the content (based on the total mass of MMA, BA, HEA and GMA) of tung oleic acid was 4%, the
pencil hardness, the water resistance, acid and alkali resistance, the tensile strength, the thermal stability and
the adhesion were all increased with the increase of GMA content (the mass of GMA as a percentage of the
total acrylic monomer mass, the same below). The pencil hardness reached 4H, the 24 h water absorption
rate was 3.31%, and the adhesion level was 0 level when the mass ratio of GMA was 12%. The film coated
on tinplate showed no change when immersed in HCl solution with a mass fraction of 5% for 144 h, and in
NaOH aqueous solution with a mass fraction of 5% for 72 h.
