介绍了化学共聚聚氨酯-丙烯酸酯(PUA)复合乳液体系及其制备工艺,将体系分成非交联型、合成交联型、成膜交联型和互穿网络型四种类型,将制备工艺分成种子乳液法聚合法、原位聚合法和溶液聚合相转化法三种方法,以此综述了PUA复合乳液的制备进展,指出原位法与相转化法制备交联型PUA复合乳液将成为今后的发展方向。 This paper introduces the chemical copolymerization polyurethane-acrylate (PUA) composite emulsion system and its preparation process. The system is divided into four types: non-crosslinked type, synthetic crosslinked type, film-forming crosslinked type and interpenetrating network type. Seed emulsion polymerization, in situ polymerization and solution polymerization phase transformation three methods, in order to review the PUA composite emulsion preparation progress, pointed out that the in situ method and phase inversion method preparation of crosslinked PUA composite emulsion will become the future Direction of development.
