摘要
合成了水性聚氨酯乳液和氨基硅油(AEAPS)微乳液改性水性聚氨酯乳液,研究了两种水性聚氨酯的性能及在织物上的涂层效果。结果表明,当氨基硅油相对于聚丙二醇的质量百分比为8.18%时,有机硅改性水性聚氨酯乳液的离心稳定性好,乳液胶膜表面硅原子的质量分数为0.92%;该有机硅改性水性聚氨酯软段相与硬段相的微观相分离增大,乳液胶膜的耐水性能和热稳定性提高;该有机硅改性水性聚氨酯乳液作为织物涂层剂时,可以赋予织物柔软、滑爽的风格。
A waterborne polyurethane emulsion and a kind of waterborne polyurethane modified with aminoethylaminopropyltrimethoxysilane （AEAPS） were prepared. Their properties and their application as fabric coating were studied. The results showed that the modified waterborne polyurethane had good centrifugal stability when the mass ratio of amino silicone oil to polypropylene glycol was 8.18% and there was 0.92% silicon on the surface of films casted from the modified waterborne polyurethane. Its microphase separation, water resistance and thermal stability were better. Furthermore, the fabric coated with the modified waterborne polyurethane had good softness and smoothness.
