SYNTHESIS AND CURING KINETICS OF BORON AND CARDANOL MODIFIED PHENOLIC RESIN

Abstract

Abstract: Aimed at the defects of phenolic resin(PF), boron and cardanol modified phenolic resin of good heat resistance and toughness were prepared. The influences of boric acid dosage and cardanol dosage on modified phenolic resin were studied. FT-IR results show that the boric acid was reacted with the hydroxyl groups in PF to generate the new cross bond. TG results show that the addition of boron to PF obviously improved its heat resistance. The curing behavior of modified phenolic resin was analyzed at different heating rates by DSC. A curing kinetics model was established for modified phenolic resin by Ozawa equation and Crane equation. The curing process parameters were determined.

Key words: boron, cardanol, phenolic resin, heat resistance, curing kinetic
