Research and Preparation of Waterborne 2K Epoxy Primer-Topcoat Integrated Coating for High-End Axles
In this paper,a kind of waterborne 2K epoxy primer-topcoat integrated coating for high-end axle was prepared.The effects of the main film-forming materials,the anti-rust pigments,the rheological additives and the defoamer on the properties and coatability of coatings were studied.The results showed that the waterborne 2K epoxy primer-topcoat integrated coating has the best performance when the epoxy emulsion AQUAER-3015 was mixed with 3EE102W at a mass ratio of 3∶1,the curing agent AQUAEPO-3126 with high hardness and good water resistance was selected,the mol ratio of epoxy equivalent and active hydrogen equivalent was 1∶0.8.the anti-rust pigments GA-4 and WJ1711 were mixed with APW-Ⅱ,and the rheological additives DeuRheo WT-102,HM-30S,Bentone LT and SCM-198 were mixed at a mass ratio of 3∶3∶3∶5,and the defoamers HOS 401W,HOS 420 and HOS 402W were selected at a mass ratio of 1∶2∶3.The prepared primer-topcoat can be applied as the field construction process required.
