| 摘 要： | 以异佛尔酮二异氰酸酯(IPDI)、聚氧化丙烯二醇(N-210)、聚氧化乙烯二醇(PEG)等为基本原料,丙烯酸羟乙酯(HEA)为封端剂,合成了非离子型双键封端水性聚氨酯(HPU)自乳化乳液,然后与甲基丙烯酸甲酯(MMA)及丙烯酸丁酯(BA)进行自由基聚合,得到丙烯酸酯改性非离子型水性聚氨酯(PUA)乳液.对这种材料进行了耐水性、粒径及热力学等方面的测试,结果表明:PUA乳液粒子有明显核壳结构,乳液的平均粒径增大；胶膜耐水性随着HPU添加量的提高而降低,胶膜的耐热性有明显提高. |

| Abstract: | A non-ionic waterborne polyurethane(HPU) was synthesized using isophorone diisocyanate(IPDI),polypropylene glycol(N-210) and polyethylene glycol(PEG) as the basic materials,and 2-hydroxyethyl acrylate(HEA)as the end capping agent,Which was then polymerized with methyl methacrylate(MMA) and butyl acrylate(BA) monomers by the thermally-initiated free radical polymerization to obtain the title product(PUA).The product(PUA) was characterized by water resistance test,particle size analysis,thermal gravimetric analysis(TGA) and differential scanning calorimetry(DSC).The experiment results showed that PUA displayed a core-shell structure,and the average particle size of PUA became larger;the water resistance of PUA films decreased with increase of HPU content,and the thermal stability of PUA films was improved greatly. |
