                     摘 要:水性聚氨酯具有优异的力学性能以及耐候性,受其结构中软段的影响,涂层硬度和耐磨
                 性不佳。采用不同类型的异氰酸酯合成聚氨酯乳液,并采用硅溶胶接枝,得到硅溶胶改性聚氨酯乳
                 液。对硅溶胶改性聚氨酯乳液进行红外表征,同时探究了硅溶胶改性对聚氨酯材料拉伸性能、硬度
                 的影响,并基于该乳液制备了汽车玻璃导 密封条耐磨涂层,对涂层的耐磨性、耐候性、附着力、耐水
                 性等进行了测试。结果表明:所研制涂层性能优于普通水性聚氨酯涂层,满足三元乙丙橡胶(EPDM)
                 汽车玻璃导 密封条涂层的使用要求。

                 resistance  were  poor. In  this  paper,polyurethane  lotion  was  synthesized  with  different
                 isocyanates,and silicone sol was grafted to obtain silicone sol modified polyurethane lotion.
                 The infrared characterization of the silicone sol modified polyurethane lotion was carried out to
                 explore the influence of silicone sol modification on the mechanical properties and hardness of

                 polyurethane materials. Based on this lotion,he wear-resistant coating of the automotive glass
                 guide  channel  sealing  strip  was  prepared. The  wear-resistant  wear,weather  resistance,

                 adhesion,water  resistance  and  other  properties  of  the  coating  were  tested. The  performance
