| 摘 要： | 用十六烷基三甲基溴化铵,十二烷基三甲基溴化铵,对微晶高岭石进行有机化处理,得到有机微晶高岭石;以有机微晶高岭石、环氧E-51复合改性,制备了有机微晶高岭石/环氧树脂复合改性的水性聚氨酯（OMMT/E-51WPU）。研究了有机微晶高岭石、2,2-二羟甲基丙酸和环氧E-51的质量分数对乳液及涂膜物化性能的影响。结果表明：当w（OMMT）=1.5%,w（DMPA）=4.0%,w（E-51）=4.0%,乳液及膜的物化性能较好,乳液呈透明蓝光,吸水率为5.9%,接触角98°,拉伸强度32MPa,断裂伸长率571%。

| Abstract: | Montmorillonite was changed to organophilic with the hexadecyltrimethy lammonium bromide and dodecyl trimethy ammonium bromides,and organic montmorillonite was obtained.OMMT/E-51 composite modification for waterborne polyurethane was prepared.The effect of OMMT,DMPA and E-51 mass percentage on OMMT/E-51 composite modificationfor waterborne polyurethane were studied.The results show that the the mass fraction of OMMT was 1.5%,the mass fraction of DMPA was 4.0%,the mass fraction of E-51 was 4.0%,the emulsion and adhesive film possessed a good performance,the water absorption is 5.9%,the water contact angle is 98°,the tensile strength is 32 MPa,the elongation at break is 571%. |
