本发明具体涉及一种多元共聚锈转化底漆专用水性防腐乳液及其制备方法。
背景技术
据统计,世界上约有20%的金属材料因被腐蚀而无法回收,我国每年金属腐蚀造成的经济损失约占国民生产总值的4%,每年因金属腐蚀造成的损失超过火灾、风灾和地震造成的损失总和。长期以来,为了减少腐蚀损失,人们采取了很多措施,如金属的电化学保护法、腐蚀介质处理法、覆盖层保护法等等。但迄今为止最普遍、最经济、最实用的保护措施还是涂料保护,涂料防腐以其施工简便、经济实用、不受设备面积、形状的约束以及具有一定装饰效果等特点而被广泛使用。
目前普通金属表面涂覆的防腐蚀涂层常常采用的是溶剂型涂料,尽管它们具有抑制腐蚀的作用,但由于它们含有对人体易造成损害的有害气体和重金属,造成了环境污染问题。同时,溶剂易燃、易爆的特点给环境带来了不安全隐患。随着人们环保意识的日益增强,水性防腐涂料成为涂料发展的重要方向。目前市面上主要是水性环氧涂料,但是水性环氧也存在一些不足,表干时间长且容易出现闪锈。

用该乳液制成的锈转化底漆具有漆膜表干快,锈转化速度快;VOC含量低;对金属基材附着力好;漆膜硬度高,漆膜防锈性能优良,耐候性好,稳定环保,防腐时效长等优点。根据涂覆厚度及工艺不同,可保持金属表面20~50年不锈蚀。由于聚合相为水相,具有环保低VOC的特点。
本发明中,所得乳液性能指标如下:固含量(%):60;粘度(mPa·s):90;表面张力(mN/m):50;PH值:2.0;热存储稳定性(55℃):60天;玻璃化温度(Tg):25℃;最低成膜温度(MFT):16℃;喷砂钢板附着力:0级;冷轧钢板附着力:一级;耐盐雾:55μm×500小时;耐盐水:55μm×18天。
本发明不局限于上述最佳实施方式,任何人在本发明的启示下都可得出其他各种形式的产品,但不论在其形状或结构上作任何变化,凡是具有与本申请相同或相近似的技术方案,均落在本发明的保护范围之内。
