Abstract

The two-part curable polyurethane foam resin composition uses little or no petroleum-derived raw materials but a plant-derived raw material so that the biomass ratio can be improved, the load on the environment can be reduced, and excellent physical characteristics can be exhibited. The two-part curable polyurethane foam resin composition includes a main agent that contains an isocyanate-terminated urethane prepolymer (A) and a curing agent that contains an isocyanate-reactive compound (B), water (C), and a catalyst (D), in which a polyol component used in (A) and (B) uses a castor oil polyol (b1) having 1.5 to 2.3 functional groups on average and a polyol (b2) prepared by addition polymerization of lactone to polytetramethylene glycol and/or polytetramethylene glycol (b3), the ratio (b1)/(b2) and/or (b3)=15/85 to 60/40 on a mass basis, and a content of the castor oil polyol (b1) is 10 to 45% by mass.
