Description

一种露天顶棚拒水布料的制备方法
技术领域
本发明涉及布料领域，具体是指一种露天顶棚拒水布料的制备方法。
背景技术
防水透气面料的主要功能有：防水，透湿，透气，绝缘，防风，保暖。从制作工艺上讲，防水透气面料的技术要求要比一般的防水面料高的多；同时从品质上来看，防水透气面料也具有其他防水面料所不具备的功能性特点。防水透气面料在加强布料气密性、水密性的同时，其独特的透汽性能，可使结构内部水汽迅速排出，避免结构孳生霉菌，并保持人体始终干爽，完美解决了透气与防风，防水，保暖等问题，是一种健康环保的新型面料。真正的防水面料长期处于潮湿的气候环境中也能经得住渗水压力，不渗水。比如长时间地在风雨交加的户外行走，跪或坐在潮湿的地面，都不会渗水。在水汽的状态下，水颗粒非常细小，根据毛细运动的原理，可以顺利渗透到毛细管到另一侧，从而发生透汽现象。当水汽冷凝变成水珠后，颗粒变大，由于水珠表面张力的作用（水分子之间互相“拉扯抗衡”），水分子就不能顺利脱离水珠渗透到另一侧，也就是防止了水的渗透发生，使透汽膜有了防水的功能。
现有的户外防水布料通常具备一定的防水效果，但是其材质较为轻薄，导致其结构强度较低，在长期的户外活动中会造成衣物表面出现破损的问题，而且采用多层面料的户外衣物着色单一，为了满足功能性需求从而导致其表面无法附着较为立体的涂料层结构。
发明内容
针对上述现有技术中结构强度较差且无法在表面喷涂复杂涂料的问题，本发明的目的在于提供一种通过合理设置达到较高强度且还通过多层材料将涂料层保护起来使其稳定的附着在布料层表面的衣物面料布料的制备方法。
本发明通过下述技术方案实现：一种露天顶棚拒水布料的制备方法，具体步骤如下：
A1．首先制备作为基层的布料层，按照质量分数计取用50-75%的聚氨基甲酸酯纤维、20-40%的聚丙烯酸正丁酯纤维和20-35%的尼龙纤维作为原材料进行混纺得到纱线并通过机器制成布料层备用；
A2．然后按照质量分数计取用邻苯二甲酸二辛酯40-60%、重质碳酸钙15-25%、铁红10-15%和甲基丙烯酸甲酯10-20%作为涂料层原料，先将甲基丙烯酸甲酯按照质量分数比例倒入邻苯二甲酸二辛酯中进行加热搅拌10-20min，然后再向其混合液中加入重质碳酸钙和铁红并持续搅拌20-25min即得到涂料；
A3．按照质量分数计取用PP40-60%、丙烯醇30-40%和丙烯酸丁酯20-35%作为薄膜层原材料进行造粒形成改性PP颗粒备用；
A4．然后将涂料均匀的涂覆在布料层一侧，待其稳定形成涂料层后，将准备好的PP颗粒加热并均匀的涂覆在涂料层上并将涂料层完全覆盖；
A5．再以质量分数计选取丁苯橡胶45-85%、氧化锌8-16%和石蜡20-30%作为压胶层的原材料进行熔融共聚得到改性丁苯橡胶并通过烫金工艺贴合在布料层设有涂料层相对一侧面上形成压胶层，从而得到衣物面料。
进一步地，所述步骤A1中混纺成纱为60-80支，并将得到的混纺纱按照110*90的纱织密度进行纺织成布料层。
进一步地，所述步骤A2中具体在140-175℃的条件下进行邻苯二甲酸二辛酯的加热搅拌过程。
进一步地，所述步骤A3中中造粒挤出温度范围为120-145℃；造粒挤出机前端温度为120-125℃，中端温度140-145℃，后端为135-138℃。
进一步地，所述步骤A5中的烫金工艺为塑料冷烫金工艺。冷烫金技术是近年来欧美印刷行业中的高科技成果。它打破了传统烫金依靠热压转移电化铝箔的传统工艺，而使用一种全新的的概念——冷压技术来转移电化箔。冷烫金技术不仅解决了许多印刷行业过去难以解决的工艺问题，而且更重要的是节约了能源，并避免了制作金属印版过程中对环境产生的污染。将冷烫金技术用于在窄幅轮转印刷机上印刷不干胶材料时，只需在原有设备上附加一些装置即可。以下介绍了冷烫金的工艺流程原理及其附加设备等情况。
本发明与现有技术相比，具有以下优点及有益效果：
本发明的方法通过合理控制各反应物之间的配比，合理控制反应条件而制备出一种适高强度且具有较好防水效果的衣物面料，本发明的防水基层为表面覆盖的薄膜层和内部的压胶层得到的固化物，耐湿性优异，并且抗冲击性等机械特性也优异的性能，粘接性能好，耐久性能好，且制备方法简单易行，适合工业化生产力。
