概要
- 論文の詳細を見る
Rigid polyurethane (PU) foams were prepared from polyol mixtures containing lignosulfonate polyol (LSP) (sodium lignosulfonate + polyethylene glycol) and molasses polyol (MP) (molasses + polyethylene glycol) by the reaction with polyphenyl polymethylene polyisocyanate (MDI) in the presence of a silicone surfactant, a catalyst and water. Thermal properties of the obtained PU foams were measured by differential scanning calorimetry (DSO and thermogravimetry (TG). Glass transition temperature (T_g) did not show obvious difference with the change of LS and MOL contents. Mechanical properties of PU's were measured by compression tests. Compression strength, yielding strength and compression elasticity increased with increasing apparent density.
