Abstract
p-toluenesulfonyl chloride is used as phenolic resin curing accelerator,the curing kinetics of p-toluenesulfonyl chloride/phenol formaldehyde resin is studied by differential scanning calorimetry(DSC).The curing reaction with different levels of p-toluenesulfonamide chloride/ phenol formaldehyde resin system is analyzed.The result shows that: with p-toluenesulfonyl chloride content increasing,the curing reaction temperature and the curing time decreases.The apparent activation energy and the reaction orde of curing reaction are calculated by Kissinger method and Ozawa method.It is found that the activation energy of curing reaction of PF system is reduced.
