Effect of Acid Curing Agent on the Foaming of Liquefied Bamboo-Based Resol Resin

Abstract

In this paper, effect of acid curing agent on the foaming of liquefied bamboo-based resol resin (PBF) were studied. The research result indicated that the optimal acid curing agent were mixture of p-toluenesulfonic acid and H3PO4, curing of PBF resol resin was analysized in detail and computer-aided software was applied for calculating thermodynamics characteristic of foaming process so that integrative assistantwas controlled better. Its apparent activation energy was 1.226 kJ·mol-1. The PBF foam showed satisfactory densities and compressive properties.
