Description

一种机器喷涂用无极灯水涂粉及其制备和喷涂方法
技术领域
本发明属于无极灯技术领域，尤其涉及一种适用于多种机器喷涂用无极灯水涂粉及其制备和喷涂方法。
背景技术
无极灯组成及工作原理：无极灯由高频发生器、耦合器和灯泡三部分组成。它是通过无极灯高频发生器的电磁场以感应的方式耦合到灯内，使灯泡内的气体雪崩电离，形成等离子体。等离子受激原子返回基态时辐射出紫外线。灯泡内壁的荧光粉受到紫外线激发产生可见光。
无极灯的工艺里，涂粉工艺在整个工艺环节中起关键作用，涂粉环节的控制到位，才能发挥无极灯低光衰、高效节能、高显色性等特点。传统的无极灯生产采用手工涂粉，速度慢、涂层厚度不均匀、成品率低，无法实现大批量生产。现有技术中，中国专利CN201010216444.0公开了无极灯粉体配料的配方及生产方法，其特征在于，所述配料组合的重量比为：三基色荧光粉：消泡剂：胶粉：氧化铝：分散剂：乙醇胺：等离子水=333:1:4:3:5:10:1000，该发明配制容易，能有效提高灯管的发光率，帮助延长灯管的使用寿命，但该发明配方的荧光粉用量多，成本较高，而且无法用于机器喷涂。
发明内容
本发明的目的在于克服现有技术的不足，提供一种机器喷涂用无极灯水涂粉及其制备和喷涂方法，工艺简单、方便生产操作、节约成本、适用机器自动喷涂，实现无极灯的大批量生产。
本发明的上述目的通过以下技术方案予以实现：
一种机器喷涂用无极灯水涂粉， 由如下按重量百分比计算的组分组成： 纳米氧化铝0.5%～1%、三基色荧光粉3%～4%、聚环氧乙烷1%～2%、表面活性剂1%～2%、分散剂1%～2%、乙醇胺0.5%～1%、去离子水88%～92%。
由于纳米氧化铝和三基色荧光粉价格较高，所述配料中这两者含量较少，节省了成本。通过加入少量的聚环氧乙烷，增加配料的粘结度，使涂层厚度较薄，适用于机器喷涂。
所述的机器喷涂用无极灯水涂粉的制备方法：将环境温度控制为20℃-30℃，湿度50%-65%，将纳米氧化铝、三基色荧光粉和去离子水放进搅拌桶中搅拌2小时；再加入聚环氧乙烷，再搅拌4小时；最后加入表面活性剂、分散剂、乙醇胺搅拌1小时；静置1小时后可用于喷粉。
上述的机器喷涂用无极灯水涂粉的制备方法，最佳环境温度控制为24℃-28℃，湿度为52℅-62℅。
所述的机器喷涂用无极灯水涂粉的喷涂方法，机器喷涂过程用100℃～150℃的温度对上述粉浆进行烤干，再经过烤粉炉用500℃～550℃高温烘烤15分钟。
与现有技术相比，本发明具有以下有益效果：
1 、配制简单，所用的纳米氧化铝和三基色荧光粉含量少，能有效节约成本；
