Description

增光片
技术领域
本发明涉及材料技术领域，具体涉及一种增光片。
背景技术
增光片广泛用于笔记本电脑，液晶显示器，液晶电视,便携式DVD播放机，车载导航***，触屏手机，数码相机、数码摄像器材等。
如将其组装在背光源前面，将光源发出的光向显示设备使用者方向聚集，可将正面亮度提高约100％(两片正交使用情况下,有横竖BEF)。并且，视角外未被利用的光，根据光的再反射效应被循环利用，并以最适当的角度聚集向使用者。但是现有增光片依然存在亮度增加达不到要求，性能有待进一步提高。
发明内容
本发明为解决上述问题，提供一种增光片。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种增光片，包括增光片本体，涂覆在增光片本体正面的正涂层，涂覆在增光片本体背面的背涂层。
所述增光片本体由以下重量份的原料组成：
聚亚苯基砜树脂15-20份，聚环氧乙烷10-20份，聚乙烯30-40份，聚邻苯二甲酰胺20-25份，聚芳酯12-18份。
所述正涂层由以下重量份的原料组成：
珠光粉6-10份，果冻蜡5-8份，云母粉4-6份，水晶土7-9份，钛白粉5-8份，立德粉3-5份。
所述背涂层由以下重量份的原料组成：
丙烯酸乙酯共聚物5-8份，发泡聚苯乙烯2-3份，全氟塑料3-5份，聚丙烯酸丁酯2-4份，琥珀2-3份，虫胶1.5-2.5份，蜜蜡1.2-1.8份，木松香1.4-2.0份，石英粉0.8-1.5份，滑石粉0.6-1.4份。
所述增光片本体、正涂层、背涂层厚度比为(20-30):1:2。
本发明的有益效果为：通过将增光片选用合适的材料，在增光片正面和背面分别镀上正涂层、背涂层，得到增光片增光效果比普通增光片高出10％-20％，同时材料廉价易得，节约成本。
