Description

一种水性丙烯酸防护浸涂料的制备
技术领域
本发明属于涂料领域，特别涉及一种水性丙烯酸防护浸涂料的制备。
背景技术
浸涂法是用将需要涂层的产品浸没在盛有涂料的槽中，停留一段时间，然后将漫过涂料的工件取出，让多余的涂料自行滴落到涂料槽中的涂装方法。浸涂法省工省料、生产效率高、涂装设备与操作简单、可采取机械化或自动化进行连续生产，最适宜于单一品种的大批量生产，主要适用于五金零件、钢质管架以及结构复杂的器材或电气绝缘材料等的涂装。目前在上述工业行业中所采用浸涂涂料一般都是溶剂型防锈漆，含有约60％的有机溶剂。这些工厂浸涂完成后都是堆放在露天场地里让其自然干燥，由于其构型复杂也无法实现流水线涂装。这就是浸涂车间底漆的现状，其涂装所用防锈漆占其涂料用量的20％左右，这部分溶剂待漆膜干燥过程中挥发到大气中，由于该有机溶剂均是有毒的，容易造成人体伤害，挥发到大气中会污染环境，并造成资源浪费。其中水性丙烯酸类涂料具有保光，保色性好，着附力强，耐候性好等优点广泛应用于各种水性涂料中。但水性丙烯酸防护浸涂料在实际应用中溶剂用量大，槽液稳定性差，涂料膜容易流挂，漏底，发花等，并在使用过程中会散发大量有害气体，污染环境和伤害人员身体。
发明内容
为解决水性丙烯酸防护浸涂料制备过程中带来的以上种种缺陷，本发明提供一种如下的水性丙烯酸防护浸涂料制备方法：
一种水性丙烯酸防护浸涂料的制备，包括如下步骤：
往搅拌机中加入20-30份去离子水，然后在高速搅拌下依次加入0.5-1份分散剂，3-5份纳米无极填料，0.2-0.5份润湿剂，0.3-0.5份PH值调节剂，0.1-0.3份消泡剂，1-2份炭黑，搅拌30-60分钟后，用球磨机球磨分散制得预制浆料；然后继续搅拌依次加入50-60份水性丙烯酸乳液，5-6份成膜助剂，3-5份防闪锈剂，2-3份增稠剂，搅拌均匀过滤即可。
根据上述过程的水性丙烯酸防护浸涂料的制备，其中，所述的分散剂为脂肪酰二乙醇胺，纳米无极填料为质量比为3：1的纳米二氧化硅与纳米二氧化钛，润湿剂为聚醚硅氧烷共聚物，PH值调节剂为三乙醇胺，消泡剂为甲基硅油，水性丙烯酸乳液为双酚A型水性丙烯酸乳液，成膜助剂为乙醇，防闪锈剂为苯甲酸铵，增稠剂为聚氨酯型增稠剂。
本发明提供了一种水性丙烯酸防护浸涂料的制备方法，本方法制备的水性防护浸涂料，槽液稳定，不容易流挂，漏底和发花等，有机挥发少，气味小，施工方便，能广泛应用于汽车，铸造工件，建筑结构等的涂装。
具体实施方式
