摘要

丙烯酸酯改性的水性聚氨酯乳液性能优异、用途广泛，是当前涂料工业研究的一个热点.采用原位乳液聚合法，先制得水性聚氨酯（PU）预聚物，然后加入引发剂和甲基丙烯酸甲酯（MMA），通过自由基乳液聚合得到聚氨酯-丙烯酸酯（PUA）复合乳液，并通过傅里叶变换红外光谱、凝胶渗透色谱、粒径分析仪等对其进行表征.研究了NCO/OH比值、二羟甲基丙酸（DMPA）含量、MMA含量及三乙胺与DMPA的摩尔比值对PUA乳液性能及外观的影响.发现当NCO/OH＝1.3～1.4，—COOH含量为2.6％左右，MMA含量为20%～30％，三乙胺与DMPA的摩尔比值为90%～100％时，所得PUA乳液综合性能较好.

Abstract

Because of the excellent properties and wide application

the water borne polyurethane emulsion modified by acrylate has become the research hot spot in coating industries.First

the water borne polyurethane prepolymer(PU) was prepared with the method of emulsion polymerization in situ

then through the free-radical emulsion polymerization

polyurethane-acrylate(PUA) hybrid emulsion was synthesized by adding initiator and methyl methacrylate(MMA).The hybrid emulsion was characterized by FT-IR

gel permeation chromatography(GPC) and Malvern particle size analyzer.Such factors as:NCO/OH ratio

the amounts of dimethylol propionic acid (DMPA) and methyl methacrylate

and triethylamine(TEA)/DMPA mole ratio

which affected the properties and appearance of the PUA emulsion were discussed.Prepared with the technology parameters 1.3—1.4 of NCO/OH ratio

about 2.6% of —COOH content

20%—30% of MMA content

and 90%—100% of mole ratio of TEA/DMPA

the PUA emulsion showed good overall properties.
