Abstract
本发明公开了一种反射性防水涂料按照重量百分比计,由4%-6%碳化镁、25%-35%氟碳乳液、5%-12%纳米空心玻璃纤维、12%-15%钛白粉、0.7%-1.0%分散剂、0.5%-0.9%消泡剂、0.5%-1.0%防腐剂、20%-30%丙烯酸酯乳液、21%-32%去离子水制备而成。本发明的涂料的隔热性能和耐水性能好。
Description
技术领域
本发明涉及反射性防水涂料。
背景技术
在各领域中,涂料的应用非常广泛,如外墙上,工业仓库,化工、石油、食品行业类贮罐及管道表面,厂房、现代化养殖场、冷冻库、民房、办公楼等建筑物上等。
传统都是为有机溶剂的涂料,该涂料的污染性严重,因此,现在大家已经大面积开始使用水性涂料,而对于外墙涂料来说,需要解决的其中一重要技术问题是隔热和防水,但现有的水性涂料其隔热和防水性能都欠佳。
发明内容
为了提高隔热反射性能和防水性,本发明提供了一种反射性防水涂料。
为达到上述目的,一种反射性防水涂料,按照重量百分比计,由如下原料制备而成;
碳化镁 4%-6%
氟碳乳液 25%-35%
纳米空心玻璃纤维 5%-12%
钛白粉 12%-15%
分散剂 0.7%-1.0%
消泡剂 0.5%-0.9%
防腐剂 0.5%-1.0%
丙烯酸酯乳液 20%-30%
去离子水 21%-32% 。
进一步的,所述消泡剂选自 SP-202 、XP-1273 中的一种或者它们的混合物,所述的防腐剂为亚硝酸盐。
本发明的有益效果是:由于加入了碳化镁、纳米空心玻璃纤维和钛白粉,因此,红外反射率可达90%以上,隔热率可到98%,从而提高了隔热效果。由于加入了氟碳乳液、丙烯酸酯乳液和纳米空心玻璃纤维,使得漆膜的厚度小,耗漆量小,气孔少,耐候性和耐水性好。
具体实施方式
下面结合具体实施例对本发明进行进一步详细说明。
反射性防水涂料按照重量百分比计,由4%-6%碳化镁、25%-35%氟碳乳液、5%-12%纳米空心玻璃纤维、12%-15%钛白粉、0.7%-1.0%分散剂、0.5%-0.9%消泡剂、0.5%-1.0%防腐剂、20%-30%丙烯酸酯乳液、21%-32%去离子水制备而成。其中,所述消泡剂选自 SP-202 、XP-1273 中的一种或者它们的混合物,所述的防腐剂为亚硝酸盐。

实施例5。
碳化镁 4%
氟碳乳液 25%
纳米空心玻璃纤维 5%
钛白粉 12%
分散剂 0.7%
消泡剂 0.5%
防腐剂 0.5%
丙烯酸酯乳液 30%
去离子水 22.3% 。
反射性防水涂料的制备方法是:在搅拌器中首先加入去离子水和分散剂、消泡剂、防腐剂,在缓慢搅拌的过程中加入碳化镁、氟碳乳液、纳米空心玻璃纤维、钛白粉之后,以1500转/分的高速搅拌分散15-25分钟,再以500转/分的低速搅拌,将丙烯酸酯乳液缓慢加入分散20-30分钟,制成本发明产品。
在本发明中,由于加入了碳化镁、纳米空心玻璃纤维和钛白粉,因此,红外反射率可达90%以上,隔热率可到98%,从而提高了隔热效果。由于加入了氟碳乳液、丙烯酸酯乳液和纳米空心玻璃纤维,使得漆膜的厚度小,耗漆量小,气孔少,耐候性和耐水性好。
