Description

一种高韧性耐撕裂帆布帐篷面料及其制备方法
技术领域
本发明涉及帐篷面料技术领域，尤其涉及一种高韧性耐撕裂帆布帐篷面料及其制备方法。
背景技术
帐篷是一种具有建筑材料功能的纺织品，用于在野外环境中隔离出一个独立安全的空间。帐篷具有简便、轻巧的特点，需要具有防风、防雨、防雪、防寒、防蚊虫的基本功能。近年来随着旅游业的发展，帐篷的销量得到大幅度增长，市场进一步扩大，人们对帐篷外观、性能的需求也进一步提高。帐篷面料由基布经表面整理制成，它的性能很大程度上影响了帐篷的使用性能。目前应用最广泛的帐篷面料是涤纶帆布，其透气透湿性能差，使用性能和附加价值不高，无法满足市场对中高档产品的潜在需求。野外帐篷对帐篷面料的撕裂强力有较高的要求，因此提高面料的撕裂性能至关重要。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种高韧性耐撕裂帆布帐篷面料及其制备方法。
本发明是通过以下技术方案实现的：
一种高韧性耐撕裂帆布帐篷面料，其是由下述重量份的原料制得：
涤纶纤维20-30，氨纶纤维20-30，棕榈纤维10-15，玻璃纤维10-15，乙烯-醋酸乙烯共聚物3-5，水性醇酸树脂3-5，苯丙乳液5-10，硅灰石粉1-2，滑石粉2-4，硬脂酰乳酸钠0.5-1，改性淀粉溶胶5-10；
其中改性淀粉溶胶由下列重量份的原料制成：玉米淀粉30-40，石墨粉10-15，硝酸钠1-2，高锰酸钾2-4，丙烯酸3-5，甲基丙烯酸甲酯6-8，15-20%浓度双氧水水溶液10-15，过硫酸铵0.5-1，十二烷基硫酸钠0.5-1，水200-300；改性淀粉溶胶的制备方法是将石墨粉按固液重量比1：1.5-1：2与质量分数为98%的浓硫酸混合后加入硝酸钠、高锰酸钾，40-50℃反应0.5-1h后依次加入水、玉米淀粉和15-20%浓度双氧水水溶液60-80℃搅拌3-4h，将pH调至中性后加入其余原料70-80℃反应1-2h，冷却后即得。
一种高韧性耐撕裂帆布帐篷面料的制备方法，包括以下步骤：
（1）将涤纶纤维、氨纶纤维、棕榈纤维和玻璃纤维按比例混纺编织，得帆布基布；
（2）将苯丙乳液、改性淀粉溶胶、水性醇酸树脂与硬脂酰乳酸钠混合后40-50℃搅拌1-2h，冷却后加入其余原料共同研磨至细度≤50μm，得涂覆剂；
（3）将（2）中的涂覆剂均匀涂覆于（1）中的帆布基布表面，先于80-90℃干燥4-6h，再于120-140℃热处理10-20min，冷却后即得高韧性耐撕裂帆布帐篷面料。
本发明的优点是：
本发明通过改性淀粉溶胶与苯丙乳液等原料复配，合成的涂覆剂与帐篷帆布基布具有良好的结合性，在基布上生成具有良好粘着牢度、透湿透气性和力学性能的涂膜，使最终得到的帆布帐篷面料既符合基本的使用要求，又具有良好的透湿透气性，涂层稳定性和均匀度高，不易脱落、开裂，防水效果和外观品质好，并且具有高韧性的特点，耐撕裂性能良好，实用性强。
