Abstract

Abstract: A waterborne epoxy chromium corrosion protective primer for AA2024-T3 Al alloy was developed by using a self-emulsifying epoxy hardener and chromium -free anticorrosion pigment. Several influencing factors on the primer properties were discussed. The results demonstrated that this waterborne epoxy primer is a viable replacement for the currently used chromate -based primer and its performance is overpass the similar imported products.

Key words: waterborne epoxy, primer, aluminum alloy, chromium-free

摘要： 针对铝合金 2024-T3防腐蚀问题，通过合成自乳化环氧固化剂，采用无铬防腐颜料，开发出一款水性无铬防腐底漆。讨论了影响漆膜性能的各种因素，并与国外同类产品进行了对比实验。结果表明:本研究制备的产品在性能上超过了进口水性环氧底漆，可作为目前含 Cr⁶⁺水性环氧底漆的替代品。
