摘要/Abstract

摘要： 采用无皂乳液聚合方法,用丙烯酸酯单体对含C C双键的水性聚氨酯进行接枝共聚改性,制得丙烯酸酯改性聚氨酯无皂乳液。探讨了反应温度、引发剂用量及搅拌速率对反应的影响;用红外光谱(IR)和透射电镜(TEM)等方法对制备的乳液粒子的形态结构及有关性能进行了分析和表征。结果表明,同改性前的聚氨酯乳液相比,丙烯酸酯改性聚氨酯无皂乳液的粒径明显增大,耐水性、耐溶剂性和抗拉强度都明显提高。

Abstract: An aqueous polyurethane-polyacrylate hybrid emulsion was prepared by soap-free emulsion polymerization of aqueous polyurethane emulsion with C C double bond modified with acrylic monomer through grafting copolymerization.The morphology and properties of composite particles of the prepared emulsion were studied with IR and TEM etc.The influences of reaction temperature,amount of initiator and agitating rate on grafting copolymerization were investigated.Compared with the unmodified polyurethane emulsion,the particle size of the prepared emulsion became larger significantly and its tensile strength,resistance to water and solvent were remarkably improved.
