PURPOSE:To obtain a resin composition capable of giving polyurethane foam useful for residential outer wall material, etc. of high flame-retarding characteristics, high strength (high compression strength) and low-water absorptivity, by blending an aqueous solution of carbohydrate, polyester resin, reaction catalyst, and polyisocyanate. CONSTITUTION:The objective composition can be obtained by blending (A) an aqueous solution and/or slurry of carbohydrate (e.g., fructose, glucose), (B) a polyester resin, (C) a reaction catalyst (e.g., dibutyltin dilaurate), (D) a polyisocyanate (e.g., tolylene diisocyanate) and, if needed, (E) foam stabilizer, and (F) flame-retarding agent, followed by stirring and mixing. |
