Description
技术领域
本发明涉及环氧树脂技术领域，特别涉及一种高光水性环氧树脂。
背景技术
由于环保法规不断强化促使涂料工业加速发展,其中发展最快的是水性涂料、粉末涂料、高固体分涂料和辐射固化涂料，其中由于溶剂价格的上涨以及环境保护法规的限制，使得以水作为溶剂成为涂料发展的一个热点。
现有的环氧树脂不含甲苯、二甲苯之类的挥发性有机溶剂，不会造成环境污染，没有失火的隐患,但是稀释得到的涂料均匀度较差，固化后的涂膜光泽暗淡，性能也有待提高。
发明内容
针对现有技术中的上述不足，本发明提供了一种高光水性环氧树脂，以解决上述背景技术中提出的问题。
为了达到上述发明目的，本发明采用的技术方案为：一种高光水性环氧树脂，按照重量百分比的原料包括：酚醛型环氧树脂占比13-20％，硅溶胶改性环氧树脂占比12-20％，KH560硅烷偶联剂3-5％，WS702表面活性剂3-5％，乙二醇丙醚占比3-8％，BYK-410流变剂占比3-8％，BYK-012消泡剂3-8％，间苯二胺占比5-10％，聚氧乙烯二胺占比10-15％，水占比10-16％，水性润湿剂占比0.3-1.2％，水性流平剂占比0.1-0.8％，纳米二氧化钛占比3-7％，纳米二氧化硅占比2-6％。
作为改进：按照重量百分比的原料包括：酚醛型环氧树脂占比13％，硅溶胶改性环氧树脂占比12％，KH560硅烷偶联剂3％，WS702表面活性剂3％，乙二醇丙醚占比3％，BYK-410流变剂占比3％，BYK-012消泡剂3％，间苯二胺占比5％，聚氧乙烯二胺占比10％，水占比10％，水性润湿剂占比0.3％，水性流平剂占比0.1％，纳米二氧化钛占比3％，纳米二氧化硅占比2％。
本发明与现有技术相比优点在于：硅溶胶改性环氧树脂是采用硅溶胶作为改性剂改性得到的，它与酚醛型环氧树脂复合能够增加水性环氧树脂组合物的干性、硬度、耐水、耐酸、耐碱以及光泽度。同时硅溶胶的存在，本身具有高活性的吸附作用，且热稳定性好，化学性质稳定、有较高的机械强度等优点，能够通过物理方式吸附水性环氧树脂组合物中的水分，提高水性环氧组合物的干度，同时其还具有疏水、消泡、泡沫稳定、防粘、润滑、上光等各项优异性能。此外，KH560硅烷偶联剂内含有的有机官能团是双键，它既能与水性环氧树脂反应，又可以和硅溶胶发生缩聚，随着KH560含量的增加，在与其他填料、稀释剂等一起作用，大大提高了后期制得的涂料的干性、硬度、耐水、耐酸、耐碱以及光泽度。
