摘要：Liquefy bamboo powder with the liquefacient of polyethylene glycol 400 and glycerin, and use the obtained liquefied product for preparing polyurethane foam materials. Results indicate that: 1) liquefaction ratio will be the highest when the proportion of PEG400 and glycerin is 80/20; 2) when the bamboo is liquefied, liquefied effect will be better if the mass ratio of bamboo powder and polyhydric alcohols is above 1: 4; 3) liquefaction ratio will be the highest when it is liquefied for 120min with 3% mass fraction of the catalyst-sulfuric acid and 170 degrees C liquefied temperature; 4) hydroxyl value of the liquefied product of bamboo powder is 333.8mgKOH/g; 5) through the adjustment of foaming formula and technology, compressive strength of polyurethane plate with the thickness of 10mm and with the density of polyurethane foam materials of 0.4g/cm(3), which is obtained from bamboo powder liquefied product is 17MPa, and the elasticity modulus is 1000MPa.
