Preparation of Bio-Degradable Polyurethane Foams from Liquefied Wheat Straw
Bio-degradable polyurethane foams were prepared from the liquefied wheat straw alcohol by a reaction with isocyanate in the presence of stannous octoate, triethylene diamine and silicone oil. The influences of the catalyst, water, silicone oil, isocyanate index(IN) on the performance of the properties of the foams obtained were investigated. Furthermore, the chemical structures, thermal performance and degradation performance of the products were analyzed.
