摘要
硅橡胶是用途最广的精细功能高分子材料之一,为了达到更好的着色效果,分别以对硝基苯胺为重氮组分,三聚氯氰和1,3,5-吡唑啉酮的一缩物为偶合组分,3-氨丙基甲氧基二甲基硅烷、3-氨丙基二甲氧基甲基硅烷和3-氨丙基三甲氧基硅烷为硅烷偶联剂,合成了一类新型黄色含硅活性分散染料。通过UV-Vis、FT-IR、1H-NMR以及MS等分析测试手段对染料进行表征。将该类染料用于硅橡胶着色,着色橡胶的干、湿摩擦牢度和耐洗牢度均达到4~5级,升华牢度也在4级以上,呈现出优异的牢度性能,且同色染料色光基本一致,着色后的硅橡胶色泽鲜艳饱满,静态力学性能保持不变。
Silicone rubber is one of the fine functional polymer materials with widest applications. For the sake of better coloring effect,a series of novel yellow silicon-containing reactive disperse dyes are designed and synthesized by using p-nitroaniline as diazonium component,the first condensation product between cyanuric chloride and pyrazolone as coupling component and 3-aminopropylmethoxydimethylsilane, 3-aminopropylmethyldimethoxysilane and 3-aminopropyltrimethoxysilane as silane coupling agents.The dyes samples are characterized by UV-Vis,1 H-NMR,FT-IR,and MS.The obtained silicon-containing reactive disperse dyes are used to color silicone rubbers,making the dry/wet rubbing and washing fastnesses of colored silicone rubbers all reach grade 4-5 and the sublimation fastness exceed grade4,which indicates outstanding performance in terms of color fastness.Such colored silicone rubbers show bright and rich colors without affecting its static mechanical properties.
