A large number of industrial waste residues are generated in the production of cresol.The component of waste residues is complex and it's difficult to separate and use effectively.It will cause serious environmental pollution when the waste is discharged into the natural environment.In order to solve this problem,an effective using way of waste residue was disclosed in the paper.The polymerization reaction was carried on and the self-drying modified phenolic resin was made by the residual phenol in industrial waste.The technologies of the self-drying modified phenolic resin and phenolic steel structure anticorrosive paint were studied.The principle of polymerization was described.The polymerization temperature,polymerization hour and pigment level were studied.The results showed the best comprehensive properties of the paint when polymerization temperature was 230℃,the time was 6-7 hours,metal ion was 3.5‰,carbon black was 3% and the radio of pigment and resin was 1:1~2.
