一种防霉抗菌、低气味PVC涂层帐篷材料
技术领域
本发明涉及复合帐篷布领域，具体是指一种防霉抗菌、低气味PVC涂层帐篷材料。
背景技术
帐篷是撑在地上遮蔽风雨﹑日光并供临时居住的棚子。多用帆布做成，连同支撑用的东西，可随时拆下转移。帐篷是以部件的方式携带，到达现场后才加以组装，所以，需要各种部件和工具。了解各个部件的名称和使用方法，熟悉帐篷的构造，才能快速、方便地搭起帐篷。
随着PVC涂层工艺材料被广泛运用建筑膜结构、帐篷篷房、卷帘门、防护罩和卡车蓬盖等领域，其良好的防水性能也被用于帐篷布材料之中，随着对防疫帐篷需求剧增。用于防疫检测的需求，要求帐篷材料便于折叠收纳、安全坚固、耐折叠等特点。同时，由于医护人员需要长时间呆在防疫帐篷里面，要求防疫帐篷具有良好的防霉抗菌性能以及使用材料达到低气味甚至无味的指标。鉴于以上，我们提出一种防霉抗菌、低气味PVC涂层帐篷材料来解决上述问题。因此，亟待研究一种防霉抗菌、低气味PVC涂层帐篷材料来解决上述提出的问题。

进一步的，所述经线和纬线为达到强度标准的高强度聚酯纤维捻制。
进一步的，所述稳定剂为钡锌或亚磷酸钙锌复合物或二盐基亚磷酸铅；所述PVC层还包括抗氧剂，所述抗氧剂为为受阻酚类抗氧剂和/或受阻胺类抗氧剂。
进一步的，所述的增塑剂为邻苯二甲酸二甲酯或邻苯二甲酸二异丁酯或邻苯二甲酸二酯或邻苯二甲酸二异丁酯或邻苯二甲酸二壬酯或邻苯二甲酸二癸酯或己二酸二辛酯。
进一步的，所述防酶剂为五氯苯酚或双氧化物。
进一步的，所述PVC层塑形工艺包括以下步骤：
1)首先将PVC层由各组分混合涂层剂，把混合涂层剂中加入适量的交联剂，然后，塑化温度在180-220℃将其涂覆在中心网层上；
2)放卷、涂覆：把准备好的中心网层在放卷机安装好，并牵引其先后通过涂布辊，经过涂布辊后中心网两侧均匀涂覆有PVC层，接着通过烘箱，最后在收卷机固定，所述烘箱设有三个，呈温度递增设置，最高温度为160℃；
3)表面处理层涂覆：柠檬酸三丁酯和发泡剂加入到分散桶内，搅拌均匀后依次加入钛白粉搅拌5分钟，加入稳定剂搅拌1分钟，再依次加入PVC树脂粉、碳酸钙、降粘剂，加速搅拌25～30分钟，分散均匀后，研磨过滤，得到表面处理层涂层糊；调整好辊轮间隙，把速度调节在5～35M/Min，将步骤2中的半成品再次经过表面处理层涂层糊涂布辊涂布、烘干，烘箱温度控制在50-75度；
4)收卷：收卷压力控制在5-20Kg之间；
