Description
技术领域
本发明属于水性工业涂料技术领域，具体涉及一种耐盐雾、耐老化水性涂料及其制备方法。
背景技术
随着人们环保意识日益增强和各国环保法规的相应出台，低VOC排放的水性防腐工业漆成为关注的焦点，市面上已经出现了多款水性防腐涂料，但存在干燥慢、初期耐水性差、耐盐雾性能不佳等缺陷。单一品种树脂制备的水性涂料在性能上还无法与传统溶剂型涂料抗衡，需要对材料进行复合改性来提升水性工业涂料的竞争力。
目前，单组分水性防腐涂料仍以环氧酯体系为主，环氧酯同时具备了环氧体系与干性油的优良特性，耐腐蚀、耐水解性优异、硬度高，但存在涂膜干燥速度慢、耐候性耐盐雾性较差、耐碱性耐老化能力不足等问题，常见的解决方法是用具有干燥速度快、光化学稳定性、硬度高、耐碱性优异、耐候性好、成膜性好的丙烯酸乳液与环氧酯化学键接枝改性，结合两者的优点，得到具有优良综合性能的产品。
专利文献CN201310539144.X公开了采用乙烯基改性法，将环氧树脂和不饱和脂肪酸进行酯化，得到环氧酯树脂，再将此环氧酯树脂与预定酸值的丙烯酸类混合单体进行自由基共聚，形成共聚产物。有机胺中和后水稀释得到水性丙烯酸改性环氧酯乳液。该制备方法的缺点是树脂合成过程不易控制，生产需大量有机溶剂，丙烯酸酯类单体不能完全反应，残留在乳液中单体较多，气味大，毒性重；合成中消耗了大量脂肪酸上的不饱和双键，使树脂的后期干性由于缺乏不饱和双键而提高不大；树脂酸值较高，漆膜的耐水性和耐腐蚀性较差。
专利文献CN201310350988.X和CN201110268907.2提供了一种制备丙烯酸改性环氧酯乳液的方法，将环氧树脂和不饱和脂肪酸进行酯化得到环氧酯树脂，将不饱和脂肪酸与(甲基)丙烯酸酯或乙烯基单体反应得到丙烯酸预聚物与其共聚而得到改性水性环氧酯。但是，树脂合成过程中需大量有机溶剂，且丙烯酸预聚物与环氧酯树脂接枝效率低，有部分未接枝的环氧酯容易从乳液中析出，乳液的储存稳定性较差，合成工艺复杂繁琐，生产效率低。
发明内容
本发明的目的在于，克服以上背景技术中提到的不足和缺陷，提供一种耐盐雾性、耐老化性能好、储存稳定性好的水性涂料，并且相应地提供一种安全环保、工艺简单的上述水性涂料的制备方法。

作为一个总的技术构思，本发明另一方面提供了一种上述水性涂料的制备方法，包括以下步骤：
(1)按上述重量百分比将去离子水和一部分水性环氧酯乳液混合，然后依次加入分散剂、消泡剂和pH调节剂，调节溶液pH为8～9，得混合浆料；
(2)将防锈颜料和填料加入步骤(1)所得混合浆料中进行研磨，研磨温度不超过65℃，研磨至细度为20μm～30μm，得颜填料浆；
(3)将剩余的水性环氧酯乳液加入到步骤(2)所得颜填料浆中，缓慢加入成膜助剂，搅拌下加入步骤(2)所得颜填料浆，再依次加入防沉剂、防锈剂、防闪锈剂、基材润湿剂和防霉剂，在1250r/min～2000r/min转速先搅拌混合均匀，再缓慢加入增稠剂，用去离子水调整体系粘度至100S/涂4杯～120S/涂4杯，调整体系pH为8～9，即得耐盐雾、耐老化水性涂料。
上述的制备方法，优选的，所述水性环氧酯乳液由如下方法制备得到：按重量百分比将环氧树脂、分子量调节剂及一部分不饱和脂肪酸混合，升温至120℃～150℃，待物料融化后开启搅拌，再升温至170℃～200℃进行酯化反应至体系酸值为5mgKOH/g～15mgKOH/g，加入剩余的不饱和脂肪酸，并降温至100℃～130℃，得反应浆料；
将丙烯酸类单体、乙烯基磷酸酯单体、有机硅中间体、引发剂混合均匀，得混合料，将该混合料滴加到所述反应浆料中，滴加时间控制在4h～6h，滴加完毕后保温3h～4h，然后升温至170℃～190℃，在此温度下反应2h～3h至体系酸值小于35mgKOH/g，再降温至100℃～140℃，加入助溶剂，降温至80℃，滴加中和剂，搅拌25min～40min，滴加去离子水，在50℃～60℃下搅拌30min～60min，过滤，即得水性环氧酯乳液。
与现有技术相比，本发明的优点在于：
(1)本发明的制备方法中，水性环氧酯乳液采用特殊的方法生产(分批加入不饱和脂肪酸)，使丙烯酸类单体反应较为完全、残留在乳液中单体较少、毒性低、酸值较低，合成的水性环氧酯乳液的储存稳定性良好、耐水性和耐盐雾性优异。
(2)在水性环氧酯乳液中添加有机硅中间体，该水性环氧酯乳液很好的将丙烯酸类树脂、环氧树酯、有机硅中间体的优点结合在了一起，油性环氧酯部分能够与空气中的氧气氧化交联，为漆膜提供优异的附着力、柔韧性和耐盐雾性等；丙烯酸树脂部分则提供乳液稳定性、为漆膜提供耐候性、丰满性和良好的表干硬度；聚硅氧烷的引入又进一步提高乳液的耐水性、耐老化性、耐温性、抗玷污性、柔软性和弹性。
(3)涂料颜填料浆的研磨制备过程中加入了部分水性环氧酯，水性环氧酯的存在可取代部分分散剂，从而减少了分散剂的用量，由此而提高了涂膜的耐水性、耐盐雾性能，并且降低了涂料的生产成本。
(4)制备的涂料为水性底面合一的涂料，不需考虑各涂层间的配套性问题，施工工序简单、干燥速快，大幅缩短了施工周期，以水为溶剂，施工中VOC排放低，对环境、人体健康的危害较小，可采用刷涂、喷涂、浸涂等多种方法施工，绿色环保，符合环保发展趋势，该涂料5％的中性盐雾达550H，QUV耐老化达600H，具有良好的耐盐雾性和耐老化性。
