Bamboo Powder Liquefaction and Resinification:Application on the Phenolic Foam
Liquefaction products of bamboo powder were obtained by using phenol as liquefier and 3% sulfuric acid as catalyst.Biomass phenolic resin was formed by the reaction of bamboo powder liquefaction product and formaldehyde under alkaline condition.The yield and viscosity of resin prepared under various temperatures and resinification times were studied.The result showed that biomass phenolic resin included 2-8% of tween-80,12-28% of p-toluenesulfonic acid,12-28% of phosphoric acid,and 10-20% of n-pentane.The viscosity measured at the foaming temperature of 70℃ was 2000-4000mPa·s.The density of phenolic foam plastic prepared from biomass phenolic resin was 20.78-81.51kg/m3,and the compressive strength was 18-57N/cm2.Infrared spectroscopic analysis was also conducted on the biomass phenolic resin and phenolic foam.
