Description
技术领域
本发明一种应用于大跨度环保料仓的防紫外线膜材，属于环保料仓技术领域。
背景技术
现有的膜材在使用过程中，受日光中紫外线的影响，容易老化破损，使用寿命收到影响。
发明内容
本发明克服了现有技术存在的不足，提供了一种应用于大跨度环保料仓的防紫外线膜材，有效延长了膜材的使用寿命。
为了解决上述技术问题，本发明采用的技术方案为：一种应用于大跨度环保料仓的防紫外线膜材，至少包括高强涤纶15％～25％、PVC树脂40％～60％、耐寒增塑剂DOA4％～6％、防紫外线剂二苯甲烷10％～20％、防霉剂羟苯甲酯4％～6％。
优选地，包括高强涤纶20％、PVC树脂50％、耐寒增塑剂DOA5％、防紫外线剂二苯甲烷15％、防霉剂羟苯甲酯5％。
其中，高强涤纶：聚酯纤维，俗称“涤纶”。是由有机二元酸和二元醇缩聚而成的聚酯经纺丝所得的合成纤维，简称PET纤维，属于高分子化合物。最大的优点是抗皱性和保形性很好，具有较高的强度与弹性恢复能力。其坚牢耐用、抗皱免烫、不粘毛。改善高温稳定性，提高高温稳定度由于聚酯纤维单丝的三维立体分布，限制了集料的侧向位移或流动，有效的改善了高温稳定性，在-40℃的低温下仍然保持柔韧性和较高的抗拉强度，有效的抵抗收缩应力，使混合料的低温抗裂性能增强，减少温缩裂缝的产生以及可以防止反射裂缝的发展。纤维单丝在混合料中的均匀分布的加筋作用，使其劲度模量增加，改善抗疲劳性能。纤维的吸附作用使沥青的粘滞度变大，提高与集料的粘结作用力。
PVC树脂：聚氯乙烯树脂，PVC树脂最原始的状态是白色的粉末状，没有任何的味道，它是不溶于水的物质，也不溶于酒精和汽油等，它的稳定性能很高，之溶于丙酮等极少数的液体，另外PVC树脂的可塑性也很高，它有放在火上进行燃烧时，即使是点燃了，只要一离开火焰，就会熄灭，另外PVC树脂在燃烧的时候颜色还会发生变化。在PVC树脂里面掺入添加剂，再经过塑化以后，经过压制机的压制以后就可以制作成不同厚度的薄膜，压制出来的薄膜再经过细心的裁剪就可以制作成塑料袋、雨衣、充气玩具扥等，因为它热胀冷缩的特性，PVC树脂制成的薄膜非常的便于收缩包装，市面上的塑料包装袋基本都是PVC树脂做成的。
耐寒增塑剂DOA：耐寒增塑剂DOA(己二酸二辛酯)为典型的耐寒型增塑剂，增塑效率高，受热增塑效率高，受热变色性小，适用于聚氯乙烯、氯乙烯共聚物、聚苯乙烯和合成橡胶等多种树脂。可赋予制品良好的低温柔软性和耐光性，制品的手感性较好。制品耐寒要求在0摄氏度至零下25摄氏度，在软制品中配方中，一般DOA的使用比例为总油份的5-20％。超过20％的风险主要是出现冒油的现象。与PVC相溶性好，能很快地均匀分散在PVC基体内。从而消弱PVC大分子间的相互作用力。增大分子间的相互移动性。增塑效果优良，是一种抗燃、无毒、环保的增塑剂。产品具有良好的光、热稳定性，以及增塑、耐抽出、迁移性小、挥发性低、相溶性好、低温柔软性能等特点，是一种广泛使用的PVC树脂增塑剂。当把增塑剂加入到聚合物中，增塑剂分子相互之间、增塑剂与聚合物分子相互之间的相互作用力是很重要。除非所有这些相互作用(增塑剂与增塑剂之间、增塑剂与聚合物之间、聚合物与聚合物之间)都是同样大小时，才可能没有增塑作用和反增塑作用。增塑剂加入聚氯乙烯树脂中，加入的比例越大，塑料制品越柔软：当加入量小于5％时，塑料制品为硬质；当加入量在15％～25％时，塑料制品为半硬质；当加入量大于25％时，塑料制品为软质；增塑剂加入量为5％～15％时会出现反增塑现象，影响产品质量，在配制时应尽量防止。
防紫外线剂二苯甲烷：一般指二苯基甲烷，抑制和延缓紫外线对聚合物造成光老化的物质，属于光吸收型，能强烈地选择性吸收紫外线，转换成无害的低能辐射。
防霉剂羟苯甲酯：为对羟基苯甲酸酯类的一种。为中性,无刺激性,几乎无毒的优良防腐剂。对霉菌、酵母菌效力较好,对细菌效力较差。在pH3～6时防腐作用最强,性质也最稳定,pH8以上逐渐水解，抑菌作用也随之减弱。对霉菌和酵母菌的抗菌作用较强，对细菌的作用稍差，主要通过破坏微生物的细胞膜，使细胞内的蛋白质变性，并抑制细胞呼吸酶和传递酶系统的活性而起到抗菌作用。分子中酚羟基上的H能发生微弱的电离，其抗菌作用受体系中H浓度的影响，因此在偏酸性的环境中对羟基苯甲酸酯能发挥较好的防腐作用。
本发明与现有技术相比具有的有益效果是：本发明通过调整防紫外线剂二苯甲烷的用量，使得膜材的抗紫外线能力显著提升，有效延长了膜材的使用寿命。
具体实施方式
本发明一种应用于大跨度环保料仓的防紫外线膜材，至少包括高强涤纶15％～25％、PVC树脂40％～60％、耐寒增塑剂DOA4％～6％、防紫外线剂二苯甲烷10％～20％、防霉剂羟苯甲酯4％～6％。
进一步地，包括高强涤纶20％、PVC树脂50％、耐寒增塑剂DOA5％、防紫外线剂二苯甲烷15％、防霉剂羟苯甲酯5％。
上面结合实施例对本发明的实施例作了详细说明，但是本发明并不限于上述实施例，在本领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
