技术领域
本发明涉及光学薄膜加工技术领域,具体涉及一种基于光学材料的复合薄膜及其制备方法。
背景技术
现在建筑领域中,玻璃是不可或缺的一种建筑材料,为了美观和实用性,现在办公和住房建筑中大多采用玻璃作为门窗的材料,特别是玻璃窗,适用范围更广。
在实用玻璃门窗后室内的保温效果也相对较差,且外部紫外线的照射也会导致夏季室内温度较高,所以为了提升室内环境的舒适度和降低能耗大多对玻璃材料表面进行贴膜处理。
玻璃贴膜除了具有隔热要求有良好的隔热性和抗紫外线外,对于建筑物窗户来说还需要有良好的透视性,现阶段为了达到较高的隔温效果和抗紫外线效果,薄膜材料中填料过多容易造成薄膜雾度上升,减低透视性,严重影响美观度。
发明内容

优选的,所述改性硅微粉的制备方法为:将硅微粉采用pH为4-4.5的酸性溶液,在50-60℃温度下水浴搅拌40-60min,后乙醇清洗至中性后混合硅烷偶联剂继续搅拌均匀后,干燥得改性硅微粉。
优选的,所述流平剂为粉末流平剂RB505。
优选的,所述引发剂为2,4-二羟基二苯甲酮、过氧化环己酮质量比1∶2混合得到。

(2)将聚氨酯丙烯酸酯、引发剂、改性纳米二氧化硅、含氢硅油、改性重晶石粉、流平剂混合搅拌均匀后涂覆在紫外隔绝层外部后固化,得复合薄膜。
