Description

一种芳纶、锦纶复合帆布的制备工艺
技术领域
本发明属于帆布制备领域，具体是一种芳纶、锦纶复合帆布的制备工艺。
背景技术
芳纶全称为“聚对苯二甲酰对苯二胺”，英文为Aramid fiber，是一种新型高科技合成纤维，具有超高强度、高模量和耐高温、耐酸耐碱、重量轻等优良性能，其强度是钢丝的5-6倍，模量为钢丝或玻璃纤维的2-3倍，韧性是钢丝的2倍，而重量仅为钢丝的1/5左右，在560度的温度下，不分解，不融化。它具有良好的绝缘性和抗老化性能，具有很长的生命周期。
芳纶广泛应用在国内纤维骨架材料行业，随着我国煤炭、电力、冶金、建材、港运等行业的发展，他们对输送带特别是高强力输送带的需求越来越大，质量要求越来越高。输送带用骨架材料的基本要求是：强度高、耐疲劳性好，粘合稳定，接头方便、重量轻、复合输送带的特定要求。
锦纶是聚酰胺纤维的商品名称，又称耐纶(Nylon)，英文名称Polyamide(简称PA)，其基本组成物质是通过酰胺键-[NHCO]-连接起来的脂肪族聚酰胺。
玻璃纤维(英文原名为：glass fiber或fiberglass)是一种性能优异的无机非金属材料，种类繁多，优点是绝缘性好、耐热性强、抗腐蚀性好，机械强度高，但缺点是性脆，耐磨性较差。它是以玻璃球或废旧玻璃为原料经高温熔制、拉丝、络纱、织布等工艺制造成的，其单丝的直径为几个微米到二十几米个微米，相当于一根头发丝的1/20-1/5，每束纤维原丝都由数百根甚至上千根单丝组成。
