Study On Primer Applied To Hydrophilic Coating Of Aluminum Flake

In this paper, with semi-continuous emulsion polymerization, core-shell structured acrylate emulsion primer with a reactive micro-gel structure was synthesized. The stability and the alkali resistance of base coat, and also its coordination with top coat were emphasized. The influences of the sort of emulsifiers, their compounding ratio and their dosage on emulsion stability of base coat were studied, and fitful emulsifiers dosage and compounding ratio were established. The structure of emulsion colloid was adjusted by using compound activators. Controlling over viscosity of emulsion should be given attention to. So, the factors affecting the viscosity of emulsion, such as the choosing of neutralization reagent, the neutralization extent, the sort and dosage of functional monomer of the shell layer and so on, were taken into account. The choice and dosage of crosslinkers of the core layer, the monomer composition of the shell layer and curing condition, etc, which have effects on the stability and physicalehemistry property of the acrylate micro-gel emulsion were also discussed here. how base coat can coordinate with top coat having hydrophilic property was related to in the end, which establishes the clew of further research on hydrophilic coat of aluminum flake.
