Description

一种耐磨地坪涂料
技术领域
本发明属于涂料领域，具体涉及一种耐磨地坪涂料。
背景技术
在地坪涂料中，最关键的一个技术指标是地坪材料的耐磨性。在GB/T 22374-2008《地坪涂装材料》中，要求溶剂型和无溶剂型地坪面漆的耐磨性为30mg(750g，500r)。但在实际使用表明，该数值要求偏低，如耐磨性在25mg左右的材料，使用一年后就有明显的磨损。
发明内容
本发明的一个目的在于克服上述现有技术缺陷，提供一种耐磨地坪涂料，采用先进的聚氨酯树脂反应技术，配合高性能的功能填料，共同提高地坪产品的耐磨性至10mg以下。
本发明解决上述技术问题所采用的技术方案为：
一种耐磨地坪涂料，由主漆和固化剂混合而成，其中主漆由如下重量份数的原料制成：羟基丙烯酸树脂40-60份、钛白粉10-15份、硫酸钡10-15份、二甲苯7-15份、溶剂3-8份、功能性填料4-7份、分散剂1-2份、流平剂0.2-0.5份、消泡剂0.2-0.5份；固化剂由如下重量份数的原料制成：异氰酸酯三聚体8-15份。
优选地，主漆由如下重量份数的原料制成：羟基丙烯酸树脂52.5份、钛白粉12份、硫酸钡12份、二甲苯10份、溶剂6份、功能性填料5.5份、分散剂1.2份、流平剂0.4份、消泡剂0.4份；固化剂由如下重量份数的原料制成：异氰酸酯三聚体12份。
优选地，羟基丙烯酸树脂的固含量为65-75％。
优选地，羟基丙烯酸树脂的固含量为70％。
优选地，溶剂为丙二醇甲醚醋酸酯。
优选地，钛白粉为金红石型钛白粉。
优选地，硫酸钡的目数为800目。
优选地，功能性填料的目数为1000目。
功能性填料可以采用本领域公知的种类，比如滑石粉、高岭土、碳酸钙等，分散剂、流平剂、消泡剂同样也可以采用本领域公知的种类。
本发明与现有技术相比，具有如下有益效果：
1)选用聚氨酯树脂体系，聚氨酯树脂中的大量的氢键保证涂层体系具有优异的耐磨性；
2)使用异氰酸酯三聚体为聚氨酯固化剂，控制反应体系的交联密度，增加涂层的韧性；
3)优化聚氨酯指数(NCO/OH)；
4)选用具有极好耐磨性的功能填料，优化添加比例。
