Description

一种具有石墨烯涂层的电焊防护服面料的制备方法及制得的 电焊防护服面料
技术领域
本发明属于纺织产品制造技术领域，具体涉及防护功能的纺织织物加工技术。更具体而言，本发明涉及一种具有石墨烯涂层的电焊防护服面料的制备方法及制得的电焊防护服面料。
背景技术
在我国，有近200万人从事电焊作业。电焊作业员工，特别是在狭窄空间进行仰姿焊接作业的员工面临着熔融金属对身体的侵害。
现有电焊防护服面料以阻燃纯棉织物为主，也有采用皮革或芳纶织物的高级电焊防护服，但价格很贵。为了阻隔电焊操作产生的熔融金属洒落在织物上造成对人体的烫伤，通常采用大于300g/m2厚重的面料。GB8965.2-2009(防护服装，阻燃防护，第2部分：焊接服)规定：焊接防护面料的经纬向强度应大于450N、15滴金属熔融滴落后的升温不超过40℃、透湿量大于6000g/m2·24h；A级防护服的续燃时间和阴燃时间均小于2s、损毁长度小于50mm；B级防护服的续燃时间和阴燃时间均小于4s、损毁长度小于100mm。
因此电焊防护服需要兼具阻燃性、导热性、透湿性以及轻量化的面料。
石墨烯是从石墨中剥离出来的单层石墨片，具有二维蜂窝状结构，碳原子以sp2杂化轨道的形式相结合，具有独特的二维碳原子结构，拥有良好的导电、导热、防紫外性能，也可以作为阻燃剂来改善聚合物的阻燃性能。目前石墨烯已广泛应用在制备纯石墨烯纤维、石墨烯复合纤维、石墨烯改性织物等新型纤维及功能复合材料等方面。采用浸轧或涂层工艺可制备疏水导电织物、导热织物、自清洁抗菌织物、超级电容器等。
公开于本发明背景部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
