The viscosity,dropping point and corrosion critical value were used to evaluate the index,and used the analytic hierarchy process (AHP),objective weight assignment method (CRITIC) and AHP-CRITIC mixed weighting method to determine the weight coefficient of each index,and combined with orthogonal test analysis to determine the best preparation conditions for anticorrosive coatings of automobiles.The results shown that the AHP-CRITIC hybrid weighting method was more scientific and reasonable than the AHP method and the CRITIC method.Comprehensive evaluation was carried out according to the determined weighting coefficient,and the optimal preparation condition of the anticorrosive coating was determined as:polymer A mass fraction 15%,the mass fraction of polymer B was 8%,the mass fraction of petroleum resin was 4%,and the mass fraction of rust inhibitor was 12%.The normal pressure was used,reaction temperature was 130～150℃,reaction time was 3h.
