| 摘 要： | 以端羟基聚丁二烯-丙烯腈(HTBN)为软段、甲苯二异氰酸酯(TDI)为硬段和端氨基硅油为改性剂,合成了端氨基硅油改性HTBN型聚氨酯(PU)。以n(-NCO)∶n(HTBN)、n(硅油)∶n(HTBN)、n(扩链剂)∶n(HTBN)和硅油加入方式为主要影响因素,采用L9(34)正交实验方法研究了各因素对端氨基硅油改性HTBN型PU的力学性能和耐介质性能的影响。研究结果表明,氨基硅油的引入能有效改善PU产物的断裂伸长率和耐介质(水、真空油、甲苯和乙醇)性能,PU产物在各种介质中的稳定性依次为真空油>水>乙醇>甲苯,R值对PU产物力学性能的影响依次为断裂伸长率>邵氏硬度>拉伸强度>定伸应力。

| Abstract: | With hydroxyl-terminated polybutadiene/acrylonitrile(HTBN) as soft chain segment,toluene diiso- cyanate(TDI) as hard chain segment and amino-terminated siloxane as modifier,a series of HTBN/polyurethanes(PU) modified by amino-terminated siloxane were synthesized. With molar ratio of -NCO to HTBN(namely R value), molar ratio of amino-terminated siloxane to HTBN,molar ratio of chain extender to HTBN,and additive wise of amino-terminated siloxane as four main factors,so the influences of various factors were i... |
