Description

一种芳纶纤维表面处理剂
技术领域
本发明涉及一种纤维处理剂，更具体地说，本发明涉及一种芳纶纤维的表面处理剂，属于芳纶纤维技术领域。
背景技术
芳纶纤维是一种具有高度取向结晶微区、主链中含有芳香基的聚酰胺类纤维材料。由于分子链段中庞大苯环的位阻作用，酰胺基团与其它原子或基团发生反应的难度很大，纤维表面具有较大的化学惰性，因此芳纶纤维与基体的粘合性能很差，必须进行特殊的工艺处理降低纤维表面取向度或采用化学方法在纤维表面增加部分活性基团，如-COOH、-OH、-NCO和一NH等，这些基团可与橡胶基体通过化学反应生成共价键或通过分子间的诱导作用提高纤维与橡胶材料的界面剪切强度和粘合性能。
20世纪80年代，荷兰阿克苏公司开发出一种粘合活化剂，只需用它对芳纶纤维表面进行一次处理即可使纤维与橡胶的粘合性能达到较高水平，但这种方法成本较高，经活化处理后的芳纶纤维物理性能有所下降。
国内有人研究了一浴活化液为水基环氧树脂，二浴浸渍液为间苯二酚一甲醛胶乳(RFL)的二次浸渍工艺以及采用RFL/活性粘合剂的一次浸渍工艺处理芳纶纤维。采用二次浸渍工艺处理芳纶线绳，一浴液应尽量不用可降低韧性的浸渍材料，但又必须保证浸胶后的线绳具有良好的粘合性能。
发明内容
