Process for the production of a lightweight cold urethane |
摘要 |
In a process for the production of a lightweight cold urethane wherein raw materials are injected into a mold in one shot, diethanolamine is added in an amount of 0.1 to 2.0 parts by weight per 100 parts by weight of the polyol. When principal raw materials including a polyol and an isocyanate, and an auxiliary ingredient mixture prepared by previously mixing auxiliary ingredients other than the polyol and the isocyanate, are injected into a mold from separate storage vessels, a water-soluble silicone foam stabilizer is added to the auxiliary ingredient mixture.
