水性环氧涂料的制备及其性能研究

Preparation and Properties of Waterborne Epoxy Coating

研究了水性环氧涂料的颜基比、水性环氧固化剂的选择、改性防锈颜料的使用、不同当量比、流变助剂的搭配以及不同硅烷偶联剂对防腐性能、抗流挂性能等的影响。最后与市售产品进行了综合对比测试。结果表明:改性磷酸锌添加5%,聚酰胺蜡浆3%,气相二氧化硅0.5%,膨润土0.2%,PVC=0.3,EEW/AHEW=1.2,使用环氧硅烷齐聚物1%,可以得到防腐性能好,抗流挂性能好的水性环氧漆,明显优于市售产品。

Study the different PVC,different waterborne epoxy curing agent,usage amount of anti-corrosive pigment,diferent EEW/AHEW,combination of rheological agent and different silane influence on the property of anti-corrosive and anti-sagging and so on.At last compare test the property with commercially products.Result show that 5%anti-corrosive pigment,3%polyamide wax,0.5%fumed silica,0.2%bentone,PVC=0.3,EEW/AHEW=1.2,and 1%epoxy silane oligomer could get a water borne epoxy coating with good anti-sagging property good anti-corrosive property and good application property,more better property than commercially products.
