The invention relates to a preparation method of a fuel steam insulating coating. The method has the following beneficial effects:
(1) after the fuel steam barrier coating is formed into a film, the film has good adhesive force and high crosslinking degree so as to form a compact low-permeability paint film, and simultaneously, the flexibility of the coating is also considered, so that the problem that the paint film has insufficient flexibility due to overlarge internal stress of a high-crosslinking system is solved.
The polyurethane-epoxy resin graft copolymerization method is adopted, firstly, polyhydroxy compound and polyisocyanate are polymerized into polyurethane prepolymer, and the polyurethane prepolymer is terminated by epoxy propanol to obtain polyurethane modified epoxy resin, wherein the epoxy resin has the characteristics of high solid content and low viscosity, integrates the advantages of the epoxy resin and the polyurethane resin, has higher crosslinking degree, and greatly enhances the adhesion and bonding performance of the system; excellent tensile strength and extremely high elongation at break are also ensured.
(2) The selected base resin should have a durable corrosion resistance to ensure that the coating has excellent resistance to strong corrosive media such as fuel oil, fuel vapor and salt water and excellent shielding effect.
Polyether polyol and polyester polyol are two types of raw materials commonly used for preparing elastic polyurethane, and the prepared polyurethane has outstanding characteristics in the aspects of low temperature resistance, flexibility, water resistance and damp-heat resistance due to the action of ether bonds in the polyether polyol. The method selects difunctional/trifunctional polyether polyol to compound, and then prepares polyurethane prepolymer with isocyanate.

Polyisocyanates have excellent chemical resistance, variability in the-NCO active sites, and are a common monomer for the synthesis of isocyanate prepolymers. By utilizing the activity difference of active sites, particularly under the use of a proper catalyst, the reaction activity difference is increased, the selectivity is high, the reaction temperature can be selected to be lower, the prepolymer with narrow molecular weight distribution is easy to manufacture, and good reproducibility is shown; the generated resin has uniform relative molecular mass distribution and good stability, and is beneficial to preparing high-solid low-viscosity products. In the synthesis process, by controlling the proportion, introducing epoxypropanol and other operations, the epoxy group is introduced into the system, the active sites are increased, the branching degree of the system is improved, and the coating has more excellent adhesion and medium resistance. The glycidol is a monomer with double functional groups, and as the glycidol molecule contains two functional groups of epoxy group and hydroxyl group, the glycidol is used for blocking isocyanate to obtain polyurethane modified epoxy resin, and is an important component in preparing the polyurethane modified epoxy resin.
