Description

一种自洁聚乙烯复合材料及其生产方法
技术领域
本发明涉及一种自洁聚乙烯复合材料及其生产方法，具体可应用于农用大棚棉被、应急帐篷、旅游帐篷、救灾帐篷、油田管道铺设、煤矿引风罩、建筑保温材料等各种领域。
背景技术
传统聚乙烯复合膜多用于农用领域，目前市场上的大棚膜使用时需要加盖草垫子或者在大棚中采用加热设备的方式，以保持大棚内温度恒定，这对于农民种菜非常的不方便，并且如果遇到霜冻天气，对于一些不耐寒的蔬菜或者水果，农民们需要费时费力的在大棚内加温，处理过程稍有迟延，可能会造成大棚蔬菜或水果的减产或者绝收，而且大棚膜强度低、寿命短，给农民们带来了很大的麻烦。
发明内容
为解决上述技术问题，本发明提供强度高、多用途的一种自洁聚乙烯复合材料及其生产方法。
为解决上述技术问题，本发明所采取的技术方案是：
一种自洁聚乙烯复合材料，为多层结构，从外到内分别为：自洁层、第一保温层、老化层、第一加强层、聚乙烯发泡膜、第二加强层、第二保温层和流滴层，各层材料均为低密度聚乙烯；第一保温层、自洁层、老化层、第一加强层、聚乙烯发泡膜、第二加强层、第二保温层和流滴层厚度比为1:0.1-0.5：0.2-0.4:0.5-0.8:0.8-1:0.5-0.8:0.5-0.6:0.1-0.5；
所述第一保温层为的成分组成为：低密度聚乙烯65-80份，发泡剂4,4-氧代双苯磺酰肼2-4份，纳米二氧化钛3-9份，无滴剂环氧乙烷加成物4-8份，阻燃剂氢氧化镁2-7份，抗氧化剂B2155-10份；
所述的第二保温层的组成为：低密度聚乙烯：86-94份，光稳定剂GW-944：0.5-0.8份，紫外线吸收剂UV531：0.6-0.9份，抗氧化剂B215：1.8-2.5份，防雾剂KF-650：0.3-1.5份，保温剂IR-05：2-10份；
第一保温层和第二保温层为经线和纬线交叉的编织层；第一保温层和第二保温层的制备方法：将保温层的材料按照配方在80℃烘干，放入螺杆挤出机中，270℃温度下挤出，拉丝，然后经温度100℃的延伸板延伸7倍；在定型板上定型，确定丝的厚宽和形状，定型板温度70℃，制得的连续长丝经收卷机形成纱管备用；将制得的纱管装入喷水织机中，按照经纬比1∶1、2∶1或者1∶2织布，得到保温层的编织材料；
所述自洁层、老化层、流滴层均采用拉伸法成型；
所述的自洁层的组成为：低密度聚乙烯：80-91.5份，纳米二氧化硅：1-5份，紫外线吸收剂UV531：0.5-6份，纳米玻璃微珠：5-10份，抗氧化剂B215：2-5份；
所述的老化层的组成为：低密度聚乙烯：90-95份，光稳定剂GW-944：2.5-3.3份，紫外线吸收剂UV531：0.6-0.9份，保温剂IR-05：2.1-6.2份；

所述第一加强层和第二加强层为经线和纬线交叉的聚乙烯网格布，经线和纬线设置为多个且相互交叉设置形成网状基层，经线和纬线之间的空隙为5mm*5mm；所述第一加强层和第二加强层经线纬线错开设置；组成为：低密度聚乙烯90-97份，乙烯-辛烯共聚物3-10份，乙撑双硬脂酰胺1-3份，硬脂酸钾1-4份，双(2，2，6，6-四甲基哌啶基)葵二酸酯为1-3份，亚磷酸三(2，4-二叔丁基苯基)酯1-3份；第一加强层和第二加强层的制备方法：将原料组分用塑料拉丝机组制备成合股丝，将上述合股丝或单丝用网格布编织机织成网格布。
本发明的有益效果是：
1)复合材料各层均采用低密度聚乙烯材料，可防水、阻燃，又能抗紫外线照射，耐磨耐用，成本更低、性能更好、结构稳定，可降解，绿色环保无污染；
2)采用网格布作为加强层，强度好，寿命长。
