Description

一种漫反射涂料
技术领域
本发明涉及一种涂料，特别是一种应用于照明领域的漫反射涂料。
背景技术
LED节能大功率光源是国家重点节能项目。一般产品，都是简单的前置一片普通的透明材料，但大功率光源的多光点，会产生叠影，而且光线刺眼，为了解决该问题，现在也有产品是前置一片毛玻璃。虽可部分解决这些问题，但会使光效率下降，与LED的节能特点背道而驰。
发明内容
针对以上存在的问题，本发明提供了一种透明的漫反射涂料，利用了光学级CaCO3及高透明哑光粉对光线无规则的漫反射和良好的透光性，使得穿过的光线传播方向发生了不规则的改变，相当于无数个次生光源。既解决了LED光源叠影，使光效达到了无影效果，变得柔和均匀，又使光能量基本不受损失，充分的彰显LED的节能效果。
本发明解决其技术问题所采用的技术方案是：
一种漫反射涂料，其特征在于其主要是由如下原料制备而成：丙烯酸树脂、哑光粉、碳酸钙、流平剂、防沉剂、消泡剂、乙酸丁酯以及PMA丙二醇甲醚醋酸酯，其中各原料的重量份数比含量为：丙烯酸树脂55～65％、哑光粉5～15％、碳酸钙15～25％、流平剂0.15～0.25％、防沉剂0.25～0.35％、消泡剂0.15～0.25％、乙酸丁酯3～5％、PMA丙二醇甲醚醋酸酯4～6％。
本发明采用的原料可直接从市场上购得，如丙烯酸树脂可采用DIC公司生产的859型丙烯酸树脂，哑光粉可采用迪高沙公司生产的OK500型产品，流平剂可采用BYK公司生产的Byk306型产品，防沉剂可采用德谦公司生产的201型产品，消泡剂可采用德谦公司生产的5400型产品，乙酸丁酯可采用三木公司生产的产品，PMA(丙二醇甲醚醋酸酯)可采用德国进口的产品。
本发明的有益效果是：本发明利用了光学级CaCO3及高透明哑光粉对光线无规则的漫反射和良好的透光性，使得穿过的光线传播方向发生了不规则的改变，相当于无数个次生光源。既解决了LED光源叠影，使光效达到了无影效果，变得柔和均匀，又使光能量基本不受损失，充分的彰显LED的节能效果。
下面结合实施例对本发明进一步说明。
具体实施方式
实施例1
把60份丙烯酸树脂投入缸中，然后加入碳酸钙20份和哑光粉10份，用高速搅拌机高速分散30min。再加入流平剂(306)0.2份，防沉剂(201)0.3份，消泡剂(5400)0.2份，再高速分散10分钟。用细度计刮细度达到25um.。用粘度计测粘度100-120S(25℃，涂4#杯)，涂料制好备用。
具体实施步骤：
备好待涂透明材片→表面处理干净→喷涂本实施例制得的漫反射涂料→烘烤→下线检查，漫反射光片制备完毕，备用。
喷涂条件：
喷涂粘度：16-20S(25℃，涂4#杯)
喷涂压力：0.3-0.4MPa
喷涂距离：15-25cm
喷枪口径：1.3-1.5mm
烘烤条件：70℃×30min    
发明效果
普通毛面透光片：透光率＜80％
涂有本实施例制得的涂料的漫反射光片，透光率＞92％，比原先透光片节能15％以上。
实施例2

具体实施步骤：
备好待涂透明材片→表面处理干净→喷涂本实施例制得的漫反射涂料→烘烤→下线检查，漫反射光片制备完毕，备用。
喷涂条件：
喷涂粘度：16-20S(25℃，涂4#杯)
喷涂压力：0.3-0.4MPa
喷涂距离：15-25cm
喷枪口径：1.3-1.5mm
烘烤条件：70℃×30min
发明效果
普通毛面透光片：透光率＜80％；
涂有本实施例制得的涂料的漫反射光片，透光率＞92％，比原先透光片节能15％以上。
