Abstract

Abstract:

Phenolic resin(PF) is widely used due to its excellent heat resistance and mechanical properties. But its heat resistance cannot meet the demand of modern science and technology. Preparation of boron phenolic resin(BPF) with excellent high temperature resistance through borate esterification method, and when n(phenol)∶n(formaldehyde) is 1∶1.5, the corresponding BPF exhibits the best heat resistance. The thermal analysis results show that the char yield of BPF is 78% at 1000 ℃, which is better than those of traditional phenolic resin and commercially available boron phenolic resin. The influence of boric acid content on the heat resistance of BPF was also discussed. When n(boric acid)∶n(phenol) is more than 0.33∶1, the char yield of BPF tends to be constant. In addition, the pre-curing and the post curing temperatures of BPF determined by DSC analysis are 160 ℃ and 220 ℃, respectively.

Key words: boron phenolic resin, heat resistance, ablation resistant ability, shear strength
