Description
技术领域
本发明涉及化工技术领域,尤其涉及一种纳米水性防水耐腐蚀涂料。
背景技术
装饰行业日渐青睐石材作为主要装饰材料,使得石材防护显得尤为重要。大家的石材防护意识和积极性也逐渐提高。
现有的石材防护方法主要有打蜡或使用酸类反应试剂与石材反应达到翻新效果。打蜡技术依靠水溶涨性低分子塑料材料,在石材表面形成覆盖层保护底材。但是硬度低,易变色,须经常抛光补蜡,耗费巨大资源,而且在每次起蜡过程中使用含有合金砂的黑色起蜡垫,严重伤害石材表面,而高溶剂强碱性的起蜡水会渗入石材形成龟裂。使用酸类反应试剂容易导致石材变薄变脆,发生开裂、变色等现象,同时不具备耐墨水,红酒,醋等的腐蚀和渗透能力,不能长期有效保证石材的美丽外观。
发明内容
为解决上述技术问题,本发明的目的是提供一种纳米水性防水耐腐蚀涂料,该涂料不和石材发生化学反应,粘附力强,不易开裂脱落,完全水性涂料经济环保,耐腐蚀性强,硬度光亮度高,制造成本低廉。
