Abstract

本发明公开的一种亚光水性丙烯酸透明罩面漆,其由重量百分比的原料制备而成:水10‑42%;防冻剂1‑10%;TD‑1269丙烯酸乳液30‑80%;ASE‑60丙烯酸乳液4‑8%;消泡剂0.1‑0.5%;成膜助剂2%‑25%;杀菌剂0.2‑0.5%。其制备方法是在慢速搅拌的条件下依次投入所列原料搅拌10分钟即可送检,合格后即可包装。本发明的优势是采用了上述配方中两种特定的丙烯酸乳液,利用了两者聚合物之间的相容性差异达到可控的消减涂膜表面光泽度的目的。简化生产工艺省去了能耗较高的消光粉高速分散过程缩短了生产时间、物料损耗和生产过程的碳排放。同时新的配方由于不采用消光粉、分散剂、防沉剂和部分消泡剂所以成本也有所下降。

Description

一种无消光粉透明亚光水性罩面漆
技术领域
本发明涉及一种不含消光粉的利用两种有相容性差异的丙烯酸乳液达到消光效果的水性罩面漆。属于建筑材料领域。
背景技术
目前水包水多彩涂料和真石漆在建筑外墙上的应用越来越多,在建筑外墙涂料产量中占的比重也将超过50%。由于水包水多彩涂料的耐水性较差、真石漆因表面粗糙孔隙率大耐沾污性较差,都需要涂刷透明罩面漆进行保护以达到相应的国家标准要求。出于产品成本和环保性能的95%以上的用户选择水性丙烯酸透明罩面漆,出于避免反光刺眼和弱化涂装表面不平整感用户一般都选择亚光效果的水性丙烯酸透明罩面漆。
目前成熟的亚光水性丙烯酸透明罩面漆配方技术基本上都是用添加二氧化硅消光粉来达到消光的目的。由于二氧化硅消光粉的吸水性较高,同时为了使二氧化硅消光粉的均匀分散、防止沉淀必须加入分散剂、防沉剂和增稠剂等亲水性成分到配方中。配方中含有这些亲水性物质会使亚光水性丙烯酸透明罩面漆的耐水白性能下降,在下雨天亚光水性透明罩面漆膜遇雨水发白影响水包水多彩涂料和真石漆的外观颜色和质感,从而影响建筑外墙面的装饰效果。
发明内容
本发明的目的之一是提供一种用于水包水多彩涂料、真石漆和需要涂装亚光罩面清漆的亚光水性丙烯酸透明罩面漆。其特点是采用添加少量不相容丙烯酸乳液代替传统配方中的二氧化硅消光粉使得配方中的亲水性物质明显减少达到明显减少亚光罩面清漆遇水的程度提高耐水白性。
本发明的目的之二是提供上述亚光水性丙烯酸透明罩面漆的制备方法。
本发明是通过以下的技术方案实现的:
一种亚光水性丙烯酸透明罩面漆,由重量百分比的原料制备而成:
所述防冻剂可以是二元或多元醇以及一切可降低水的冰点的物质。
所述的杀菌剂优选为异噻唑啉酮类杀菌剂。
所述的消泡剂优选为矿物油型消泡剂。
所述的成膜助剂优选为醇酯十二。
所述的TD-1269丙烯酸乳液作为成膜物质,是江苏日出化工有限公司生产的透明罩面漆专用丙烯酸乳液。
所述的ASE-60丙烯酸乳液为美国陶氏生产的产品。
上述亚光水性丙烯酸透明罩面漆的制备方法是在慢速搅拌的条件下依次投入所列原料搅拌10分钟即可送检,合格后即可包装。
本发明的优势是采用了上述配方中两种特定的丙烯酸乳液,利用了两者聚合物之间的相容性差异达到可控的消减涂膜表面光泽度的目的。简化生产工艺省去了能耗较高的消光粉高速分散过程缩短了生产时间、物料损耗和生产过程的碳排放。同时新的配方由于不采用消光粉、分散剂、防沉剂和部分消泡剂所以成本也有所下降。
