摘要： 针对金属基材表面残留的水性防锈剂引起后续涂装质量下降的问题，研制一种在水性防锈剂残留基材上具有良好涂层外观和性能的水性双组分环氧涂料，研究了水性环氧树脂、润湿剂、助溶剂和功能填料的选择对涂层性能与外观的影响。结果表明：水溶性环氧树脂 YPWE-406A和丙烯酸杂化环氧乳液 AEH-20按照质量比 1∶3复配，制备的环氧涂料润湿性好、表干速度快。通过添加 0. 2%两亲性硅氧烷类润湿剂 HOS 2413、0. 4%非离子型炔二醇类润湿剂 Dynol-607和 6%混合溶剂（异丙醇、丙二醇丁醚和二丙二醇丁醚质量比为 1∶1∶1），能够进一步降低涂料表面张力、提高表干速度和改善成膜性能，制备的环氧涂层在防锈剂残留基材上无印痕，附着力达到 0级，耐中性盐雾性达到 480 h。同时，添加片状填料滑石粉或云母粉可以改善涂层在防锈剂残留基材上的外观和性能。

Abstract: Waterborne two-component epoxy coatings with good appearance and performance on the substrate with residual waterborne rust inhibitor was developed to solve theissue of deteriorating coating quality caused by residual waterborne rust inhibitor on thesurface of metal substrate. The effects of waterborne epoxy resin，wetting agent，co-solvent and functional filler on the performance and appearance of the coating were studied. The resultsshowed that the main resins of the coating system were YPWE-406 A and AEH-20，which were compounded according to the mass ratio of 1∶3，0. 2%HOS 2413 and 0. 4% Dynol-607 were added as the wetting agent，6% compound solution（a mixture of IPA，PNB and DPNB in a 1∶1∶1 mass ratio）and 5% flake structure filler were added，then the waterborne two-component epoxy coatings with best performance were obtained，which could solve the coating problem ofwaterborne two-component epoxy coatings on the substrate with residual waterborne rust inhibitor. 

Key words: waterborne two-component epoxy coatings, waterborne rust inhibitor, residue, paint imprints, corrosion resistance
