Description

防老化遮阳网布
技术领域
本发明涉及遮阳网布，尤其涉及一种防老化遮阳网布。
背景技术
遮阳网，是近10余年来推广的一种最新型的农、渔、牧业、防风、盖土等专用的保护覆盖材料。夏季覆盖后起到一种挡光、挡雨、保湿、降温的作用。冬春季覆盖后还有一定的保温增湿作用。主要用于蔬菜、香菇、花卉、食用菌、苗木、药材、人参、灵芝等作物的保护性栽培和水产家禽养殖业等，对提高产量等有明显的效果。
传统的遮阳网是采用聚乙烯，高密度聚乙烯、PE、PB、PVC、回收料、全新料等为原材料，经紫外线稳定剂及防氧化处理制备而成，具有抗拉力强、耐老化、耐腐蚀、耐辐射、轻便等特点。实际上传统遮阳网布的制备主材料并非具有抗紫外的能力，是通过紫外线吸收剂或稳定剂的作用下才能达到遮光的效果，这种单纯添加紫外线吸收剂的做法通常存在一定的弊端，很多抗紫外线吸收剂如二苯甲酮类化合物属于小分子的有机物，容易发生挥发和迁移的问题，从而造成制备成的遮光网布在使用的过程中抗紫外能力以及遮光能力降低的较快，从而影响了其使用寿命，容易发生老化。
如何从遮阳网布本身的制备材料出发以增加其抗紫外抗老化能力，减少外添加抗紫外线吸收剂的使用，将会一定程度上解决上述问题。
发明内容
发明目的：为了解决现有技术中所存在的问题，本发明提出了一种具有优异的抗紫外线功能，化学性能稳定，使用寿命长，具有持久的遮光率的防老化遮光网布。

所述中间弹性层网布的纺丝材料以质量计包括：聚醚酯弹性纤维20％-40％、聚烯烃类弹性纤维30％-50％、余量的双组份复合卷曲纤维。
更为优选的，所述外抗紫外层网布厚度为0.1-0.3mm。
更为优选的，所述内抗菌层网布厚度为0.2-0.3mm。
