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%. 
