一种环保遮光高防水的蓬盖材料及其制备方法
技术领域
本发明涉及一种蓬盖材料，尤其涉及一种环保遮光高防水的蓬盖材料及其制备方法。
背景技术
蓬盖材料是人们广泛使用的一种的产品，主要应用于交通、运输、油田、煤矿、建筑、军工、民用及旅游等方面，成为人类生活不可或缺的组成部分。随着国民经济的高速发展，已促使交通运输、港口码头、露天仓储、勘探开采、国防装备等领域对材料的需求呈不断增长的趋势。同时，地震、洪水等自然灾害频发，国家应急保障和避险系统的完善已提升到了很重要的地位，加强城市应急保障和避险系统的建立需开发多功能、高性能的蓬盖材料，以提升应对各种自然灾害和突发事件的应急处理能力，给保增长、保民生和保稳定一个有力的支持。
篷盖材料作为产业用纺织品中传统的大类产品，服务于社会各相关领域，是纺织工业新的经济增长点。为了提高篷盖材料的强度及耐候性能，通过结构和生产工艺、原料配方的升级，是未来产品的研发重点。
以往的篷盖材料，通常因为骨架材料与膜材贴合后，存在气泡或夹杂异物，基布的毛细效应会因为雨水渗透至篷盖材料的骨架中，导致发霉、抗剥离性能下降等问题的发生，从而严重影响产品质量。
发明内容
为了解决现有蓬盖材料功能单一，遮光与防水效果较差的缺陷，本发明提供了一种环保遮光高防水的蓬盖材料，结构紧实，织物遮光性能优异，并且阻燃性能好，并具有一定的防紫外线功能，可以适应不同室外环境的应用。
本发明还提供了该蓬盖材料的制备方法。
为了实现上述目的，本发明采用以下技术方案：
本发明提供了一种环保遮光高防水的蓬盖材料，包括表面层，基布层与背面层；所述基布层由经过防水处理的涤纶网络丝作为经纱，经过阻燃处理的涤纶弹丝作为纬纱织造而成；其中，所述的防水处理是在涤纶网络丝的原料中加入质量分数为0.01-0.5％的复合防水剂；所述的阻燃处理是在涤纶弹丝的原料中加入质量分数为0.1-0.2％的复合阻燃剂。
作为本发明的一种优选方案，所述的复合防水剂包括以下重量份数的组分：甲基MQ硅树脂20-30份，水性环保丙烯酸树脂30-45份，渗透剂10-20份与分散剂5-10份。
作为本发明的一种优选方案，所述的复合阻燃剂的制备方法为：1)在保护气氛氛围中，将100重量份的双(2-羟乙基)甲基牛脂基季铵盐、400重量份的去离子水与50重量份丙烯腈-丁二烯-苯乙烯混合，调节pH至10-12，85-90℃下搅拌40-60min，再加入氢氧化镁与碳化硅混合，加热回流120-150min，冷却至室温；然后多次清洗，真空干燥，得到表面接枝的氢氧化镁；
2)在保护气氛氛围中，将10重量份的步骤1)得到的表面接枝的氢氧化镁，5重量份的聚硅氧烷与1.5重量份的催化剂混合，加热回流，反应完成后冷却至室温，洗涤多次后干燥，得到复合阻燃剂。
作为本发明的一种优选方案，所述的催化剂为质量分数3.5％的氯铂酸异丙醇溶液。
作为本发明的一种优选方案，所述表面层包括以下重量份数的原料：炭黑20-30份，气相二氧化硅0.5-2份，乙二胺基聚醚多元醇0.5-2份，双组分聚醚型聚氨酯50-70份与紫外线吸收剂1-5份。
作为本发明的一种优选方案，所述背面层包括以下重量份数的原料：聚丙烯酸树脂30-60份，改性纤维20-30份，乙酸乙酯10-20份与聚氨酯20-30份。
作为本发明的一种优选方案，所述改性纤维的制备方法为：将碳纤维和碳酸钾混合球磨，经200-220℃煅烧20-30min后160-180℃条件下干燥25-30min，再对其进行盐酸酸洗、去离子水冲洗和60-80℃干燥1-2h，经350-420℃煅烧3-5h后得到碳纤维；将碳纤维放入反应釜，加入去离子水制备成悬浊液，以转速180-200r/min进行搅拌，向悬浊液中缓慢加入等质量的氯化锑和水合氯化亚锡，同时保持悬浊液pH值恒定，氯化锑和水合氯化亚锡加入完成后继续搅拌45min，后静置沉淀、抽滤，在干燥研磨至300-400目得到改性碳纤维。
本发明提供上述的环保遮光高防水的蓬盖材料的制备方法，包括以下步骤：
1)制备经过防水处理的涤纶网络丝，制备经过阻燃处理的涤纶弹丝，制备表面层浆料，制备背面层浆料；
2)经过防水处理的涤纶网络丝作为经纱，经过阻燃处理的涤纶弹丝作为纬纱织造基布；
3)将步骤1)制得的表面层浆料转移至基布的其中一个表面以形成连续分布的表面层，烘干；将步骤1)制得的背面层浆料转移至基布另一表面以形成连续分布的背面层，烘干；
4)将步骤3)得到的基布进行后处理，得到环保遮光高防水的蓬盖材料。
与现有技术相比，本发明具有以下有益效果：
1)本发明采用由经过防水处理的涤纶网络丝作为经纱，经过阻燃处理的涤纶弹丝作为纬纱织造而成的基布，提高其防水性能与阻燃性能，再在基布的表面层中加入了遮光功效与紫外线吸收剂，在基布的背面层加入了防静电效果较好的改性纤维，在使用时，提高了蓬盖材料的遮光性，防水性，防紫外线性，阻燃性与防静电功能；
2)本发明的复合阻燃剂将氢氧化镁和碳化硅通过双(2-羟乙基)甲基牛脂基季铵盐进行化学接枝改性，以降低表面极性，然后用聚硅氧烷封端包覆，聚硅氧烷的碳碳双键和表面接枝了碳化硅、双(2-羟乙基)甲基牛脂基季铵盐与丙烯腈-丁二烯-苯乙烯的氢氧化镁发生加成反应，形成Si-O-Si键的核壳结构包裹在氢氧化镁表面，使得氢氧化镁由原来的亲水变成了超疏水状态，并且Si-O-Si键在高温燃烧过程中，会形成陶瓷结构包裹在材料表面，形成致密的碳层，隔绝空气，达到阻燃的目的；
3)本发明的使用锡锑包覆对碳纤维进行改性，提供了抗静电能力；
4)本发明的表面层与背面层的浆料不含有DOP等增塑剂，通过Reach标准，其安全性能可达到服装用级别，对人体和环境无害。
