In order to improve the open loop curing temperature reduction process, this paper studies the open loop curing temperature reduction and heat resistance of benzoxazine. Based on DSC and bisphenol-A, the curing reaction of benzoxazine intermediates under different catalytic conditions is analyzed. It is found that the curing temperature of benzoxazine is significantly reduced with the addition of acidic catalyst, and the activation energy is also further reduced. It can be seen that under the acidic catalysis, the secondary reaction of benzoxazine open loop will be changed to some extent.
