    • A method of making a foam product including the steps of reacting an isocyanate component with a polyol component and foaming with a foaming agent to form a self-supporting intermediate foam material. The isocyanate component is present in excess of a stoichiometric quantity needed to react with the polyol component. The self-supporting intermediate foam material is then contacted with water and the self-supporting, intermediate foam material is heated to form a foam product, the water reacting with the remaining unreacted isocyanate component. The self-supporting, intermediate foam material formed by the first foaming step is rigid or semi-rigid at room temperature but it can be softened by heating to enable it to be used for deep draw molding in a successive cure molding process without cracking, splitting or being destroyed. Once the self-supporting, intermediate foam material is contacted with water or steam in the final cure molding process to react the remaining isocyanate component, the material becomes a finally cured, rigid or semi-rigid foam material which will not soften on heating. The self-supporting, intermediate foam material can be laminated with facing materials or reinforced with glass fiber--non-woven cloth or the like to give a composite panel which exhibits stiffness, heat insulation, acoustic insulation, moisture resistance and is light in weight so that it can be used for a molded ceiling or door panel in an automobile or a partition or screen for interior use.
    • 本发明是一种刚性或半刚性发泡材料的制造方法,其包括发泡工艺以制备实际上热塑性的发泡材料,其中异氰酸酯组分在有机发泡剂和/或水的条件下与多元醇组分反应 存在一定量的异氰酸酯组分超过反应中的多元醇组分和水的化学计量当量,以及连续的固化模塑方法,其中所述实际热塑性发泡材料与水或蒸汽接触以使剩余的异氰酸酯组分反应 其中加热时用水。 通过第一发泡方法获得的发泡材料在室温下未达到剩余异氰酸酯的刚性或半刚性的最终固化,但是通过加热软化可以在连续固化成型工艺中用于深拉伸成型 没有裂缝,分裂或拆除。 然后在最终的固化成型工序中与水或蒸汽接触,使剩余的异氰酸酯成分与水反应,进行最终的固化,从而成为刚性或半刚性的泡沫材料,而不会因加热而软化。 中间的实际热塑性泡沫材料可以与面料材料层压或用玻璃纤维无纺布等增强,以提供具有优异性能的复合板,例如轻质,刚度,隔热性,隔音性和耐湿性,适用于模塑 天花板或车门面板等,以及用于室内使用的隔板或屏幕。
