Description
技术领域
本发明属于一种工业防腐涂料技术领域，涉及一种双重固化水性防腐工业涂料环氧富锌底漆。
背景技术
与本发明接近的水性富锌底漆如“水性环氧富锌底漆及其制备方法”申请号：201210374279.0 ，公开水性环氧富锌底漆及其制备方法，水性环氧富锌底漆由主剂和固化剂组成，主剂和固化剂的质量配比为4：1；主剂的组成为：成膜助剂，防沉剂一，防沉剂二，胺类环氧固化剂，分散剂，消泡剂，填料和锌粉；固化剂的组成为：环氧乳液，防沉剂三，防闪锈剂和去离子水。制备方法包括如下步骤：主剂和固化剂的制备以及主剂和固化剂按照质量配比=4/1的比例进行配漆。以水作为主要分散介质，具有非常低的可挥发性有机物含量，低气味，对人体危害小，不燃，贮存、运输和使用过程中均体现了其独有的安全性，消除了由于大量有害溶剂聚集构成的安全隐患，对施工人员身心健康的危害也降至最低，并且能够满足集装箱生产线快节奏生产效率的要求。“应用于铁路支座上水性环氧富锌底漆的制备方法”申请号：201410213318.8，提出了一种应用于铁路支座上水性环氧富锌底漆的制备方法，包括组份A和组份B，所述组份A包括：水性环氧固化剂6-10％、高纯度锌粉80-84％、缓蚀剂1-2％、环保磷酸锌1-3％、助剂A：1-3％、羟乙基纤维素0.3-0.7％、成膜助剂4.8-7.4％；组份B包括：水溶性环氧树脂60-80％、助剂B：1-2％、去离子蒸馏水18-39％。由于对配方技术做了更优异的调整，使其在具有非常优异的贮存稳定性的前提下，完全达到环保标准，大大降低了VOC的排放量，同时利用了缓蚀剂与金属发生“螯合”反应，并且在环保磷酸锌的辅助下，将耐盐雾性能提升至2000小时，所有综合性能完全符合TB/T1527-2011铁路钢桥保护涂装标准要求，完全可以替代现铁路支座行业正在使用的油性特质环氧富锌底漆，大大降低了对环境污染的几率。“室温固化双组份水性环氧富锌底漆”申请号201510032583.0，公开了一种室温固化双组份水性环氧富锌底漆，其包括A组分和B组分，其中A组分含有如下质量份的组分：E51环氧树脂8～10份，环氧稀释剂0.8～1份，助溶剂3.5～8份，有机膨润土0.9～1.2份，锌粉60～90份，云母氧化铁0～25份；B组分含有如下质量份的组分：水性环氧固化剂45～65份，水34～50份，基材润湿剂0.5～2.0份。该底漆较传统的三组份水性环氧富锌底漆具有施工方便，节约操作时间，防腐性能优异等优点。
现在使用的富锌涂料主要还是溶剂型的环氧富锌、醇溶型的无机硅酸锌底漆，生产和使用过程需要使用30-50%的有机溶剂，严重污染环境，影响施工人员健康。因此，开发水性环氧富锌底漆产品是环境保护的需要、产品发展的必然，而现有水性环氧富锌底漆主要存在问题有：
一、产品质量固体份低，目前水性产品的不挥发份停留在50%左右，不超过70%，有效成分低，达不到行业标准不挥发份≥70%的要求；
二、产品硬度低、耐化学品差，很少产品的耐盐雾能够超过400h；
三、产品需添加缓蚀剂、防止漆膜在固化过程中出现生锈，且产品施工在金属表面存在半年内就出现生锈问题；
四、价格高于溶剂型环氧富锌底漆；
五、国家暂未限制溶剂型涂料的生产、施工使用；
以上原因是造成水性环氧富锌底漆不能被市场接受的主要原因。
发明内容
本发明的目的在于提供一种双重固化水性环氧富锌底漆的生产方法，以解决水性涂料难以在钢结构领域大规模使用的技术难题，全面取代溶剂型涂料。
为了达成上述目的，本发明的解决方案是：
一种双重固化水性环氧富锌底漆的生产方法，采用下列原料制成：
液体环氧树脂8-12%、共溶剂4-9%、消泡剂0.2-0.4%、分散剂0.4-0.8%、流平剂0.3-0.6%、防沉剂0.5-1.2%、高纯锌粉62-84%，防锈颜料0-19%，合计100%，作色漆A组份；
511#改性胺加成物28-32%、水28-32%、丙苯乳液40%，合计100%，再加消泡剂0.2-0.4%，作固化剂B组份；
按行业标准HG/T3668-2009II型标准进行检测，配比：A:B=4:1，容器中搅拌混合后呈均匀状态。
本发明的优化例一：液体环氧树脂10%、共溶剂5%、消泡剂0.2%、分散剂0.5%、流平剂0.3%、防沉剂0.6%、高纯锌粉83.4%（纯度99.9%以上），合计100%作色漆A组份；511#改性胺加成物28%、水32%、丙苯乳液40%、消泡剂0.2%，合计100.2%作固化剂B组份；按行业标准HG/T3668-2009II型1类标准进行检测，配比：A:B=4:1，容器中状态,搅拌混合后呈均匀状态。
本发明的优化例二：液体环氧树脂11%、共溶剂5%、消泡剂0.2%、分散剂0.5%、流平剂0.3%、防沉剂0.6%、高纯锌粉72%（纯度98%以上）、防锈颜料11%，合计100.6%作色漆A组份；511#改性胺加成物30%、水30%、丙苯乳液40%和消泡剂0.2%，合计100.2%作固化剂B组份；性能按行业标准HG/T3668-2009II型2类标准进行检测，配比：A:B=4:1，容器中状态，搅拌混合后呈均匀状态。
本发明的优化例三：液体环氧树脂12%、共溶剂6%、消泡剂0.2%、分散剂0.6%、流平剂0.3%、防沉剂0.6%、高纯锌粉62%（纯度98%以上）、防锈颜料19%，，合计100.7%作色漆A组份；511#改性胺加成物32%、水28%、丙苯乳液40%和消泡剂0.2%，合计100.2%作固化剂B组份；性能按行业标准HG/T3668-2009II型3类标准进行检测，配比，A:B=4:1；容器中状态，搅拌混合后呈均匀状态。
采用上述方案后，本发明的优点是：
一、利用液体环氧树脂、少量共溶剂等制备含锌组份，使水性富锌底漆实现与溶剂型环氧一样的双组份包装；
二、采用改性胺加成物乳化液体环氧树脂,实现产品水性化（水稀释）；
三、在固化剂中添加丙苯乳液，提高产品性能，乳液提高漆膜的致密性、降低介质浸透性、提高产品硬度、耐化学品性和不挥发份；
四、在固化剂中添加水，使产品实现初乳化，为直接用水稀释调整施工粘度打基础；
五、产品涂膜固化是利用环氧树脂与改性胺固化剂进行反应交联，挤出成膜物分子间的乳液，使乳液填充在漆膜锌粉颗粒间的空隙和漂浮在漆膜表面，水挥发丙苯乳液实现自交联固化成膜，涂膜实现双重固化；
六、双重固化水性环氧富锌底漆产品拥有比溶剂型产品：更好的漆膜外观、封闭性、更高的硬度和耐腐蚀性能，更高的不挥发份、净味、超低的VOC排放，对金属提供更长久的防腐保护，进而全面取代溶剂型涂料，达到甚至超过溶剂型产品性能。

操作工艺：在反应釜中加入配方量的液体环氧树脂、共溶剂，低速搅拌均匀，在低速搅拌下加入消泡剂、分散剂、流平剂、防沉剂搅拌均匀，在低速搅拌下，缓慢加入配方量的高纯度锌粉、防锈颜料，加完后，高速搅拌分散20min，取样检测合格后过滤包装作色漆A组份；在反应釜中加入配方量的511#改性胺加成物、去离子水，低速搅拌均匀，然后在低速搅拌下加入配方量的丙苯乳液，最后加入消泡剂加完后分散5min，取样检测合格后过滤包装作固化剂B组份。
本发明制备的水性环氧富锌底漆，性能上与溶剂型环氧富锌相媲美，涂膜有长效保护作用并能全面推广使用。本发明产品净味,涂膜固化先通过环氧树脂与改性胺固化剂进行反应交联，挤出混合物分子间的乳液，使乳液填充在漆膜锌粉颗粒间的空隙和漂浮在漆膜表面，丙苯乳液通过水挥发自交联成膜，使产品实现双重固化，性能得到大幅度提高：漆膜表面光滑平整致密，快干、净味、施工用具和产品稀释采用水作溶剂；可以快速重涂，更好的漆膜外观、更好的封闭性、耐腐蚀性能，更高的不挥发份、对金属提供长久的防腐保护，进而全面取代溶剂型涂料，产品性能完全满足现有溶剂型环氧富锌涂料HG/T3668-2009的II型1、2、3类标准要求。
本发明的双重固化水性环氧富锌底漆是双组份产品、价格与现有行业标准的溶剂型环氧富锌底漆类似、性能满足溶剂型富锌底漆要求；配方不添加防闪锈剂、缓蚀剂、含重金属的原料，以水为稀释剂调整施工粘度，清洗施工设备，净味、超低VOC排放，对施工人员和环境无影响，可与水性或溶剂型涂料产品配套，是种能完全满足钢结构使用的水性防腐涂料，有望替代现行溶剂型环氧富锌底漆，从而减少有机溶剂挥发造成的大气污染，保护环境，造福社会。
