Description

一种LED灯饰用水性涂料
技术领域
本发明涉及散热涂料制备技术领域，尤其是一种LED灯饰用水性涂料。
背景技术
众所周知热量传递有三种基本方式：热传导(导热)、热对流、热辐射。与传统光源相比，LED灯具的显著优点是节能环保、体积小、结构紧凑、方便嵌入各种灯具。LED灯具的散热技术一直是灯具使用寿命长短的决定因素。若灯具的散热效率设计较高，不但可以减少LED灯具的光衰，保护灯珠，延长LED的使用寿命，还可以减轻灯具的重量，拓展其应用范围。
LED散热涂料是一种可涂布LED灯饰外表面以提高散热效果的节能涂料。
发明内容
本发明的目的在于提供一种LED灯饰用水性涂料。
本发明的技术方案如下：
一种LED灯饰用水性涂料，各组分按质量百分比计为：
其中，水性丙烯酸树为三木化工EA1620和WTB5124的混合物，其重量比为1:0.5-2。
具体地，所述水性氨基树脂为乙二醇改性氨基树脂。
其中乙二醇改性氨基树脂的方法可以为：将甲醛溶液调节pH>9，加热至 60℃，然后加入三聚氰胺，保持pH，回流搅拌缓缓加热，然后加入适量的乙二醇，在90℃的条件下反应5小时，最后在80℃条件下旋蒸2小时，冷却后得乙二醇改性氨基树脂。
具体地，所述碳纳米管直径为20nm-30nm，长度为200nm-500nm，
具体地，所述水性流平剂为离子型丙烯酸酯溶液或聚醚改性有机硅。可以选择BYK-381。
具体地，所述云母与碳纳米管的质量比为2:1。在此比例下，可以使涂料的散热效果达到最优。
具体地，所述附着力促进剂为改性环氧磷酸酯。可以选择励欧化工 NEO-8980，可以较大幅度的提升材料的附着力。
具体地，所述水性润湿剂为多官能基的烷醇胺或共聚体。可以选择 DISPERBYK-181。
本发明的有益效果是：
(1)本发明的一种LED灯饰用水性涂料是一种以水为稀释剂的水性材料，由于所用的水性丙烯酸树脂液同时含有羟基和羧基，既可以起到亲水作用，又能起到固化作用，只需要中和就可以得到储存稳定性好的水溶液。
(2)通过调配氨基树脂的使用量，可以调节涂膜的硬高、柔韧性、耐水性、耐溶剂和附着力等性能，可以适用不同用户要求；
(3)本发明的一种LED灯饰用水性涂料中的水性氨基树脂优选为乙二醇改性氨基树脂，进一步增加了体系的相容性，并有效增加了漆膜的韧性以及体系的附着力；
(4)本发明的一种LED灯饰用水性涂料中，控制云母与碳纳米管的质量比为2:1，在此比例下，可以使涂料的散热效果达到最优。
(5)本发明的一种LED灯饰用水性涂料，使散热器在同样负载下温度下降4～10度，或者在温升相同的情况下负载能力提高20-30％左右。
具体实施方式
为了使本发明目的、技术方案和优点更加清楚明白，以下结合实例，对本发明进行进一步的详细说明。
本发明的一种LED灯饰用水性涂料，其中各组分组成为：
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
