Polyurethane foam is disclosed having improved flame retardancy, charring, and intumescent properties. The foam is prepared from a reaction mixture comprising at least one isocyanate or diisocyanate, one blowing agent, one surfactant, one catalyst, and one reactive hydroxyl-terminated oligomeric liquid melamine derivative. The resulting foam provides substantial resistance to burning. A melamine-derived compound having at least alkyl or alkoxy groups, with hydroxy (—OH) termination(s) have proved to be particularly useful in connection with polyurethane foam.
所公开的聚氨酯泡沫具有更好的阻燃性、炭化性和膨胀性。该泡沫由一种反应混合物制备而成,该混合物至少包含一种异氰酸酯或二异氰酸酯、一种发泡剂、一种表面活性剂、一种催化剂和一种活性羟基封端低聚液态三聚氰胺衍生物。由此产生的泡沫具有很强的耐燃烧性。事实证明,至少具有烷基或烷氧基、羟基(-OH)末端的三聚氰胺衍生化合物在聚氨酯泡沫中特别有用。
