Effect of Bamboo Powder on Curing Behaviors of Liquefied Bamboo-Based Resol Resin

Abstract

Differential Thermal Analysis(DTA) and Differential scanning calorimetry (DSC) were used to study the effect of Bamboo Powder(BP) on the curing behavior of two types of liquefied bamboo-based resol resin(PBF). DTA analysis shows that the addition of bamboo powder to the PBF resin leads to low temperature and broad peaks in the DTA curves. It also accelerates the addition reaction in the curing process of PBF resin and reduced the peak temperature, activation energies for PBF resin . Bamboo Powder reduced the activation energies for resins because the bamboo powder maybe had selfcatalysis effect. The lowest activation energy for a PBF resin probably appeared about at pH 11.0 under alkaline conditions.

Eucalyptus veneer with a thickness of 1.0 mm, spruce-pine-fir (SPF) timbers, and polyurethane insulation material were purchased from Fujian Heqichang Bamboo Product Co., Ltd. (Fujian Province, China); Phenolic (PF) resin adhesive with solid content at 52.4% was purchased from Taier Heavy Industries Co., Ltd. (Guangdong Province, China); bamboo liquefied-resin insulation material was selfdeveloped (for details, see Liu et al 2012;Zhang et al 2016).…”
