摘要
研究了一种基于植物多酚/多胺的芳纶帘线绿色环保浸胶体系(PTA浸胶液),并对比PTA浸胶液与间苯二酚-甲醛-胶乳(RFL)浸胶液浸渍处理的芳纶帘线与橡胶的粘合性能。衰减全反射傅里叶转换红外光谱和X射线光电子能谱分析结果表明,经PTA浸胶液浸渍后,丁吡胶乳包覆在芳纶帘线表面,其含有能参与橡胶硫化的C=C键,帘线的浸渍效果良好;与RFL浸胶液浸渍的芳纶帘线相比,PTA浸胶液浸渍的芳纶帘线的原始及热老化后H抽出力稍高,室温停放后H抽出力保持率提高;扫描电子显微镜分析表明,PTA浸胶液浸渍的芳纶帘线与橡胶基体的界面粘合良好。
A environment-friendly PTA dipping system(PTA dipping solution)of aramid cord based on plant polyphenols/polyamines was studied,and the adhesion of the PTA dipped aramid cord and rubber was compared with that of the resorcinol-formaldehyde-latex(RFL)dipping solution dipped aramid cord and rubber.The attenuated total reflection Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analysis results showed that,butadiene pyridine latex was coated on the surface of aramid cord after the impregnation with PTA dipping solution,and it contained C=C bonds that could participate in rubber vulcanization.Besides,the dipping effect of aramid cord with PTA solution was good.The H pull-out force of the aramid cords from rubber was tested,and the H pull-out force of the aramid cord dipped with the PTA dipping solution compared with that of the aramid cord dipped with the RFL dipping solution was slightly high,before and after the heat aging.In addition,the retention rate of the H pull-out force after room temperature parking was improved.The analysis results of scanning electron microscope showed that the interface adhesion between the aramid cord dipped with the PTA dipping solution and rubber matrix was better.
