摘　　要：以水性环氧树脂乳液为基料,改性聚酰胺固化剂,锌粉为防锈颜料,氨基偶联剂为助剂,研制了双组份水性环氧富锌防腐底漆。探讨了树脂的选择、固化剂用量、锌粉用量、硅烷偶联剂用量等对水性环氧富锌防腐底漆性能的影响。在最佳配比条件下,环氧当量∶H当量=1.2∶1,锌粉占干膜质量的75%,硅烷偶联剂为富锌涂料质量的1%时,漆膜性能优异,可应用于各种重防腐蚀领域。Using waterborne epoxy emulsion as the binder and modified polyamine as the curingagent, zinc power and aminesilane coupling agents for fillers and ad d itiv es, a two - component waterborne epoxy zinc rich primer was prepared. The influence of several factors including the kind and dosage of waterborne epoxy emulsion, modified polyamine, zinc power and aminesilane coupling agents on coatings performance was discussed. Under the best conditions,epoxy equivalent ： H equivalent = 1.2 ： 1 ,zinc powder accounts was 7 5 % of the dry film q u ali ty , aminesilane coupling agent was 1% of the quality of zinc rich p a in t ,the coatings had excellent performance, can be applied to various heavy anti-corrosion field
