Description
技术领域
本发明涉及一种增亮膜的制备方法。
背景技术
增亮膜在液晶领域以及显示照明领域广泛应用,增亮膜通过折射、全反射、光积累等光学原理,可以使各方向的光线向中心视角集中,进而提升 LCD 面板的亮度和控制可视角度。增亮膜具有很好的光学效果,但是增亮膜的胶层树脂不具有阻燃性,在生产存放中容易燃烧,且在一些对阻燃性能有要求的领域的使用中受到限制。
同时,为了符合现阶段社会所提倡的环保理念,无机金属水合物阻燃剂是最优的选择。但是,金属水合物又与大多数聚合物的相容性较差。
因此,如何提高增亮膜的光学性能且选择适合的阻燃方式增强阻燃性,是目前液晶阻燃领域中的重要课题。
发明内容
为了克服现有增亮膜的上述不足,本发明提供一种阻燃性强的增亮膜的制备方法,制备方法环保且阻燃性能强。
本发明解决其技术问题的技术方案是:一种阻燃性强的增亮膜的制备方法,包括以下步骤:
S1:将聚碳硅烷倒入装有有机溶剂的容器中,采用机械搅拌使聚碳硅烷完全溶解,获得聚碳硅烷溶液。
S2:取无机阻燃剂通过混合机混合均匀。
S3:将聚碳硅烷溶液滴加到无机阻燃剂粉体中,其中无机阻燃剂30-60质量份,聚碳硅烷5-10质量份,用混合机混合混合均匀后放入烘箱中在90-135℃下烘干;
S4:烘干后在再次将烘干所得物质通过混合机混合均匀,得到的改性物。
S5:将改性物加入基材中混合均匀,制备得到阻燃性强的增亮膜。
优选的,所述的有机溶剂为二甲苯,或苯甲醚,或环己烷;所述的无机阻燃剂为氢氧化镁,或氢氧化铝,或水滑石。
优选的,在步骤S5中,改性物和基材的质量比为0.5-10:100。
本发明的有益效果在于:针对无机金属水合物阻燃剂的缺陷,复合阻燃是成为阻燃技术发展的一个优化方案。聚碳硅烷作为陶瓷先驱体聚合物材料,可以裂解产生陶瓷相,利用这种变化,增加无机阻燃剂间的致密性,从而增阻燃性能,且其中的改性剂对环境基本无污染。
