Description

一种隔热透光车窗玻璃
技术领域
本发明属于车窗玻璃技术领域，具体涉及一种隔热透光车窗玻璃。
背景技术
汽车玻璃包括汽车前挡风玻璃，汽车侧面车窗玻璃和后窗玻璃，是一种特种玻璃。汽车玻璃的种类很多包括普通的绿色玻璃，采用SPD技术的变色玻璃，具有偏光效果的镀膜玻璃，以及具有防爆功能的聚碳酸酯车窗玻璃等。
随着中国汽车产销量的不断提高，汽车玻璃的市场也在不断扩大，其中具有各种差异化功能的特种汽车玻璃的销量也在不断增加。但是市场的车窗玻璃几乎都没良好的隔热效果，在夏天时，阳光透过车窗，将汽车内部的座椅和方向盘等部件晒得非常烫手，汽车内空气也变得异常灼热，这让驾驶者需要开启空调来制冷，从而造成更高的燃油消耗，还可能因为车内温度过高导致汽车自燃等灾难性事故的发生。而车窗玻璃使用常规的隔热膜后，又会对自然光线造成遮挡，影响车内环境的采光。
发明内容
针对以上问题，本发明的目的在于提供一种隔热透光车窗玻璃，该车窗玻璃具有良好的结构强度和透明度，并且隔热效果良好，在夏天可以减轻车外的空气和阳光对车内环境的加热作用，冬天时可以降低车内的热量损失。
一种隔热透光车窗玻璃，所述玻璃包括两层钢化玻璃基板和中间的透光隔热夹层；所述透光隔热夹层的成分按照质量份数包括：丙烯酸分散料40-50份，水性聚氨酯固化剂8-10份，纳米复合材料5-10份，成膜助剂1-3份，附着力促进剂1-2份，流平剂0.5-1.5份，消泡剂0.3-0.8份，去离子水50-80份。
优选的，所述透光隔热夹层的成分按照质量份数包括：丙烯酸分散料44-46份，水性聚氨酯固化剂8-9份，纳米复合材料6-8份，成膜助剂2-3份，附着力促进剂1.5-2份，流平剂1-1.3份，消泡剂0.4-0.6份，去离子水65-70份。
优选的，所述纳米复合材料中含有：纳米有机锡、纳米氧化锌、纳米氧化铟锡、纳米氧化钛和纳米氧化硅五种物质，五者的质量比为7:8:2:1:5。
优选的，所述丙烯酸分散料是由甲基丙烯酸甲酯、丙烯酸丁酯、甲基丙烯酸和过氧化二叔丁基四种物质等量混合在丙酮中进行共聚反应，然后将PH调节至中性，再加水除去有机溶剂，得到的水性分散体。
优选的，所述成膜助剂为醇酯类成膜助剂，流平剂为聚丙烯酸酯类流平剂，消泡剂为聚醚改性有机硅类消泡剂。
其中，所述透光隔热夹层材料的制备方法为：按照质量份数将丙烯酸分散料、水性聚氨酯固化剂、纳米复合材料、成膜助剂和去离子水混合均匀，然后加入附着力促进剂、流平剂和消泡剂，继续搅拌，搅拌均匀后送入到超声波分散设备中进行超声波分散处理。
所述车窗玻璃的制造方法为：将外层钢化玻璃基板切割成所需尺寸，玻璃边缘研磨光滑并清洁干燥，在除静电无尘洁净间中，将夹层材料均匀涂布在水平放置钢化玻璃基板表面，然后将两块玻璃基板合片，再经过60-70℃的温度干燥20-30min后，将玻璃基板边缘进行密封处理，得到所需隔热透光车窗玻璃。
优选的，所述钢化玻璃基板的厚度为2-3mm，夹层的厚度为0.2-0.4mm。
本发明提供的一种耐隔热透光车窗玻璃，与现有技术相比，具有以下优点：
该玻璃由双层钢化玻璃基板和中间的隔热透光夹层构成，玻璃的结构强度高，可以抵御较强的冲击力，玻璃的透明度高，透光效果好，可以为汽车内部提供一个良好的光照环境。
车窗玻璃中间使用该夹层材料后，使得其具有良好的隔热效果，在夏天时，可以抵御车窗外面的炎热空气和光线对车内环境的加热作用，到了冬天还可以降低车内的热量损失，让汽车内部的环境更加宜人，降低汽车空调的能源消耗，是一种非常环保节能的车窗玻璃。
