技术领域
本发明涉及光学功能膜技术领域，具体涉及一种光学功能膜及其制造方法。
背景技术
随着科技的快速发展，液晶显示器(LCD)、等离子(PDP)显示器、有机电致发光(EL)显示器等显示器因其本身的轻、薄特性被广泛应用于各种电子显示装置，如：电视、个人电脑、手持便携式终端(PHS)等。一般情况下，电子显示装置无论是在室内或者室外使用，环境中的光均会照射至显示装置的表面，照射至显示装置表面的光因通过不同介质的界面产生了反射，使得光的穿透度下降，或者因多重反射，造成眩光或者重影，进而导致显示装置的画面显示品质降低。

所述粘结剂树脂粘结剂树脂为聚乙烯醇系树脂或纤维素系树脂。
所述二氧化钒的微粒为通过水系合成法而制备的含有二氧化钒的微粒。
一种光学功能膜的制造方法，包括以下步骤：
(1)将光学树脂、聚乙炔类高分子导电材料、聚碳酸酯、丙烯酸酯、氢氧化锂、粘结剂树脂、氧化钒微粒、紫外线稳定剂、紫外线吸收剂、抗氧化剂、稀释剂按照重量份称取，在250-350℃下在离心薄膜反应器中进行离心；然后利用双轴卧式反应器进行聚合反应；
(2)将步骤(1)中得到的材料加入双螺杆挤出机,在双螺杆挤出机熔融挤出，然后冷却，就能得到光学功能膜。
与现有技术相比，本发明的有益效果是：本发明的光学功能膜光学透明性好，抗冲击强度高，具有优异的紫外线激发发光并反射蓝光的功能，可以吸收不可见的紫外光，转化为波长较长的蓝光或紫色的可见光，可以广泛用于制作各类隔蓝光液晶屏幕保护膜、隔紫外太阳能隔热膜等产品；同时本发明的光学功能膜能够根据温度环境而调节近红外屏蔽率的热变色性、雾度低、即使长期使用时也具有优异的耐裂纹性及密合性。
