In this study,polyether polyols and polyfunctional isocyanate were used as main raw materials to prepare NCO blocked isocyanate prepolymer.In addition,fluorinated hydroxyl resin and small molecule hydroxyl epoxy resin were used as modifier to synthesize a new-type of low surface energy aluminum alloy template paint.The factors affecting of template paint's key proterties were studied,the prepared coating has high cross-linking density,strong adhesion to aluminum alloy and high wear resistance,it also has low surface energy,excellent hydrophobic and stain resistance performance,which can provide durable corrosion protection against oil,chemical media and environmental factors for aluminum alloy template.
