  • Vacuum pyrolytic oil from pyrolysis of WPCB was used to synthesize the thermosetting phenolic resin(TPR) via condensation polymerization with formaldehyde and catalyzed by NaOH. The effects of synthesis on the solid content of PR were evaluated. According to the result of the orthogonal experiments, the optimum conditions of the synthesis process were determined: 38.5 g of vacuum pyrolysis oil, 40 g of formaldehyde, 10 g of the catalyst, the reaction temperature was 60℃ for 3 h,and then change to 95℃ for 3 h. It is found that the amount of catalyst was the main factor in the reaction. The structure and properties of the synthesis of products were analyzed with the infrared spectrum (IR) and thermogravimetric analysis (TG),the mechanics performance of the product was also tested. The results proved that the spectrogram of TPR synthesized by pyrolysis oil appeared characteristic peak such as CH2, CH—OH. The heat resistant temperature of TPR was above 300℃,and the tensile strength was 39.6 MPa. It is similar with phenol PR synthesized by phenol. The results of research showed that PR synthsized by the vacuum pyrolytic oil is feasible.
