Anti-wrinkle underwater anti-crude oil adhesion gel coating and preparation method thereof

Abstract

The invention relates to the technical field of polymer marine antifouling, in particular to an anti-wrinkle underwater anti-crude oil adhesion gel coating and a preparation method thereof.The preparation method comprises the steps that hydrophilic polyether monomers, hydrophobic polyether monomers, diisocyanate, epoxy resin, a catalyst and a hydrophilic solvent are evenly mixed and react to obtain a prepolymer; uniformly stirring the prepolymer and an amino chain extender to obtain a polyurethane solution; the preparation method comprises the following steps: coating a base material with a polyurethane solution, soaking the base material in water, drying the base material, and soaking the base material in water again to obtain the anti-wrinkle underwater crude oil adhesion-resistant gel coating; the hydrophilic polyether monomer comprises any one or more of bisphenol A diglycidyl ether, polyethylene glycol diglycidyl ether, hexanediol diglycidyl ether and 1, 4 butanediol diglycidyl ether; the hydrophobic polyether monomer comprises any one or more of polytetrahydrofuran and polypropylene glycol. The gel coating provided by the invention has excellent wrinkle resistance and antifouling effect, and also has good mechanical properties and environmental friendliness.
