摘要： The present invention describes a process for producing flame-retardant polyurethane foams. The process of the invention includes the use of hyperbranched, nitrogen-containing polymers for providing flame retardancy to polyurethane foams. The amounts used of the hyperbranched compounds are preferably from 5 to 20% by weight, based on the polyol component. The N content of preferred nitrogen-containing compounds is at least 2% by weight. The N content of the polyurethane foams of the invention is from 1 to 8% by weight from the hyperbranched polymer. Compounds in particular used are hyper-branched polyureas, hyperbranched polyamides, and in particular hyperbranched polylysines, hyperbranched polyisocyanurates, and hyperbranched polyesteramides.An advantage of the use of the compounds of the invention is that the polyurethane foams can be rendered flame-retardant without the use of, or by using markedly reduced amounts of, halogen-containing flame retardants. It is likewise possible to achieve a marked reduction in, or to avoid, the use of additive, halogen-free flame retardants. The processing profile and the mechanical properties of the polyurethane foams are thus significantly improved. The compounds of the invention are preferably used in such a way that the foams are rendered flame-retardant without use of halogen.The hyperbranched polymers of the invention can provide flame retardancy either to flexible polyurethane foam or to rigid polyurethane foam.
摘要翻译：本发明描述了制造阻燃聚氨酯泡沫体的方法。本发明的方法包括使用超支化的含氮聚合物来为聚氨酯泡沫提供阻燃性。基于多元醇组分，超支化化合物的用量优选为5至20重量％。优选的含氮化合物的N含量为至少2重量％。本发明的聚氨酯泡沫的N含量为超支化聚合物的1〜8重量％。特别使用的化合物是超支化聚脲，超支化聚酰胺，特别是超支化聚赖氨酸，超支化聚异氰脲酸酯和超支化聚酯酰胺。使用本发明化合物的优点在于，聚氨酯泡沫体可以在不使用或显着减少量的含卤阻燃剂的情况下变成阻燃剂。同样可以实现显着减少或避免添加剂，无卤素阻燃剂的使用。因此，显着改善了聚氨酯泡沫的加工轮廓和机械性能。本发明的化合物优选以不使用卤素使泡沫成为阻燃剂的方式使用。本发明的超支化聚合物可以提供柔性聚氨酯泡沫或硬质聚氨酯泡沫的阻燃性。
