Abstract

本发明涉及一种反光膜制造工艺，尤其是一种反光膜玻璃微珠单层共面植珠生产工艺。采用气动植珠与静电植珠相结合的工艺，选用热固型的胶粘剂使玻璃微珠均匀分布于胶粘剂表面，形成单层共面的玻璃微珠层，具体步骤为：先将玻璃微珠在烘箱中预加热；预热后的玻璃微珠放入流化珠槽中；使走膜的过辊带正电荷，玻璃微珠带负电荷；从流化珠槽底部鼓入热空气，使玻璃微珠粘于胶粘剂层表面；经过热复合钢辊和橡胶辊的压合，使玻璃微珠均匀紧密分布于胶粘剂表面。本发明所述的反光膜玻璃微珠单层共面植珠的生产工艺可以大大提高产品的表观状况，使表面均匀一致，增强反光强度，还可以减少原材料的消耗，降低成本。

Description

反光膜玻璃微珠单层共面植珠生产工艺
所属技术领域
本发明涉及一种反光膜制造工艺，尤其是一种反光膜玻璃微珠单层共面植珠生产工艺。
背景技术
反光膜按其不同的逆反射原理可分为玻璃珠型和微棱镜两大类。玻璃微珠型反光膜生产中最重要的工序是植珠环节，传统工艺多采用将植珠面直接与静止的玻璃微珠接触的办法，容易造成玻璃微珠分布不均匀，无法紧密排列，玻璃微珠层层重叠，严重浪费原材料，并影响反光亮度，另外，一般采用冷复合，玻璃微珠的陷入深度不容易掌握。
发明内容
为了克服现有技术的不足，本发明的目的是提供一种采用静电植珠与气动植珠相结合工艺，并在压合时采用热复合，使玻璃珠紧密均匀排列于材料表面的反光膜玻璃微珠单层共面植珠生产工艺。
本发明解决其技术问题所采用的技术方案是：一种反光膜玻璃微珠单层共面植珠生产工艺，具体操作步骤为：
a.先将玻璃微珠在烘箱中预加热到80～90℃；
b.预热后的玻璃微珠放入流化珠槽中；
c.采用静电装置，使走膜的过辊带正电荷，玻璃微珠带负电荷；
d.从流化珠槽底部鼓入80℃的热空气，使玻璃微珠粘于胶粘剂层表面；
e.经过热复合钢辊和橡胶辊的压合，热复合钢辊的热压温度为60～70℃，气压控制在0.3～0.35MPa，使玻璃微珠均匀紧密分布于胶粘剂表面，陷入胶粘剂层的深度为微珠直径的1/2左右。
本发明所述的反光膜玻璃微珠单层共面植珠的生产工艺可以大大提高产品的表观状况，使表面均匀一致，增强反光强度，还可以减少原材料的消耗，降低成本。
附图说明
图1是本发明的工艺图；
图2是依照本发明所述工艺生产的玻璃微珠层结构示意图。
图中：1.玻璃微珠  2.流化珠槽  3.热复合钢辊  4.橡胶辊  5.胶粘剂层
具体实施方式
下面结合附图与实施例对本发明作进一步的描述。
如图1所示，经烘箱预加热到80～90℃的玻璃微珠1放入流化珠槽2中，中间用可透气的板隔开，板上分布有均匀气孔，孔径小于最小玻璃微珠的直径。采用静电装置，使走膜的过辊带正电荷，玻璃微珠1带负电荷。从流化珠槽2底部鼓入80℃的热空气，使玻璃微珠粘于胶粘剂层5表面。经过热复合钢辊3和橡胶辊4的压合，热复合钢辊3的热压温度为60～70℃，气压控制在0.3～0.35MPa，使玻璃微珠1均匀紧密分布于胶粘剂表面，陷入胶粘剂层的深度为微珠直径的1/2左右。
