Description

一种新结构吸附性窗纱 技术领域
本发明属于纱窗技术领域，具体涉及一种新结构吸附性窗纱。
背景技术
在窗户玻璃的里侧或外侧一般都设有窗纱，窗纱主要起到防止蚊虫进入且不影响室内通风换气、保护隐私等作用。目前公知的窗纱为网格结构，由纵横交错的材料编制而成，而纵横交错的材料是由单一类型的材料所构成的，这种窗纱在使用一定时间后会发生变形、破损等情况，降低窗纱的使用寿命。
另外，在现代社会，一味追求的经济的快速发展已酿成了严重的环境污染，导致空气质量下降，空气中PM2.5含量增加。而普通的窗纱只能阻隔蚊虫进入，烟尘、粉尘和飘尘等大量颗粒污染物很容易通过窗纱通孔换气的过程中进入室内，从而严重的影响到室内的空气质量，故只能关闭窗户。现有技术中也有许多窗纱的改进产品，其最终的目的也都能实现一定的防雾霾的目的。如申请号为“201410006669.1”的中国专利公开了一种防PM2.5窗纱，通过在纱窗上复合微孔膜来过滤空气中的可吸入过滤物。但是这种窗纱上的微孔膜出现饱和后对颗粒污染物的吸附能力会下降，并且清理的时候也较为麻烦，容易造成窗纱微孔的阻塞，影响透气量。
发明内容
针对现有窗纱的单一材料构成易降低使用寿命、吸附颗粒物后不易清洁的问题，本发明提供了一种新结构吸附性窗纱，以解决上述问题。
本发明提供的新结构吸附性窗纱，包括骨架粗线和加密细线；多根骨架粗线纵横交错，形成多个四边形网格；横向或/和纵向的相邻两根骨架粗线之间设置至少一根的加密细线，将四边形网格分割为多个子网格；骨架粗线和加密细线表面均涂有颗粒吸附涂料。
进一步的，所述骨架粗线直径为0.3-0.8mm。
进一步的，所述加密细线直径为0.05-0.3mm。
进一步的，所述骨架粗线为不锈钢、聚酯、聚酰胺、玻璃纤维材料中的一种；所述加密细线为不锈钢、聚酯、聚酰胺、玻璃纤维材料中的一种。
负离子有利于身体健康，可以吸附空气中的苯、氨等有毒有害的纳米级小分子极性物质，负离子粉体能够持续释放负离子，有效改善室内空气质量，祛除室内空气中甲醛、甲苯，氨等有害污染物质；纳米二氧化钛能够在光的作用下长久杀菌，可以将空气中的甲醛、苯、甲 苯、二甲苯、氨、TVOC等有害污染物氧化分解成二氧化碳和水，有效控制细菌、病毒等的交叉感染，达到控制细菌繁殖和净化空气的目的，并且纳米二氧化钛能反射、散射紫外线，透过可见光，可以进行紫外线防护；胶体石墨粉添加在涂料中可以降低涂层的摩擦系数，降低，降低颗粒污染物的粘附能力，避免难以去除导致窗纱难以清理，但胶体石墨粉加入过多，粘附能力过低，涂层对空气中颗粒物的吸附效果会大打折扣，因此对于胶体石墨粉的加入量需要寻找一个平衡，既能保证涂层表面具有较低的摩擦系数，又要保证很好的颗粒吸附效果。
进一步的，所述颗粒吸附涂料包括如下原料及其重量份数：丙烯酸树脂乳液30-45份，负离子粉5-10份，纳米二氧化钛8-13份，胶体石墨粉8-16份，表面活性剂10-18份，助剂12-20份，水20-35份。
进一步的，所述胶体石墨粉的粒径为2-5μm。
进一步的，所述的表面活性剂是阳离子型表面活性剂、阴离子型表面活性剂、非离子型表面活性剂的一种；所述的阳离子型表面活性剂是胺盐型、季铵盐型、杂环型、啰盐型的一种或几种；所述的阴离子型表面活性剂为羧酸盐、硫酸酯盐、磺酸盐、磷酸酯盐的一种或几种；所述的非离子型表面活性剂是聚氧乙烯型、多元醇型的一种或几种。
进一步的，所述助剂为消泡剂、增稠剂、成膜助剂、膨润土、分散剂、乳化剂、流平剂、防沉淀剂、耐摩擦剂、防结皮剂、消光剂中的一种或几种。
进一步的，所述窗纱包括多种颜色，可使窗纱更美观。
本发明的有益效果为：
本发明提供的新结构吸附性窗纱，通过采用较粗的骨架粗线作为窗纱的基本骨架，在骨架粗线之间设置较细的加密细线，不仅保证了良好的通风性和透光性，还有效增强了窗纱的坚固性和耐用性，提高了窗纱的使用寿命；该防雾霾窗纱表面喷涂了颗粒吸附涂料，在使用时不但能有效阻挡了雾霾的进入，而且还保障了室内负离子的含量，沉降室内局部灰尘颗粒、消除有害气体、杀灭细菌等，从而达到清新室内空气的目的；另外，胶体石墨粉的加入以及其用量的限制，既保证了涂层表面具有较低的摩擦系数，方便后期吸附的污染物的清理以及室内外的通风换气，又保证了很好的颗粒污染物吸附效果，使室内空气保持清洁。

颗粒吸附涂料包括如下原料及其重量份数：丙烯酸树脂乳液45份，负离子粉10份，纳米二氧化钛13份，胶体石墨粉16份，羧酸盐18份，消泡剂10份，增稠剂10份，水35份。
其中，骨架粗线为不锈钢材料，加密细线为玻璃纤维材料；骨架粗线直径为0.4mm，加密细线直径为0.1mm；胶体石墨粉的粒径为2-5μm。
对比例1
对比例1与实施例1的窗纱不同的是，所述颗粒吸附涂料中不含有胶体石墨粉，其余相同。
对比例2
对比例1与实施例1的窗纱不同的是，所述颗粒吸附涂料中胶体石墨粉为20份，其余相同。
对实施例1、实施例2、对比例1、对比例2的窗纱进行性能测试：在四间同样的房间内开展试验，每个房间设有两扇对流的窗户，将实施例1、实施例2、对比例1、对比例2的窗纱各安置于一个房间的两扇窗户上，在房间内加入空气污染物PM2.5微尘，湿度保持为50％RH，接着加入CO、CO2、H2S等燃烧物的有害气体，通过综合质量检测仪检测室内空气质量，并记录不同时间的空气质量指数。
在测试完成后，对四间房间的窗纱上的污物进行清理，采用干净的抹布进行擦拭，并对抹布擦拭下来的脏污的容易程度进行判定：实施例1、实施例2、对比例2制得的窗纱的脏污去除较为容易，而对比例1的脏污去除非常困难，说明了胶体石墨粉的加入有效解决了窗纱清洗麻烦的问题。
实施例1、实施例2、对比例1、对比例2的窗纱性能测试结果如表1所示：
表1-窗纱性能测试结果
