Abstract

resumo "misturas de poliol de poliuretano estabilizadas contendo derivados de agente de sopro de olefina halogenado" a presente invenção diz respeito a imidazol e/ou seu derivado como catalisador de espuma de poliuretano ou poliisocianurato na presença de agentes de sopro olefínicos halogenados de baixo potencial de aquecimento global (gwp), tal como hidrocloro-olefina (hcfo) hcfo-1233zd. mais particularmente, a presente invenção diz respeito a composições de catalisador compreendendo imidazol e/ou um seu derivado. a presente invenção também diz respeito a formulações de pré-mistura estáveis e resultantes de espumas de poliuretano ou poliisocianurato. um método para estabilizar a mistura de espuma termocurada compreende combinar: (a) um poliisocianato e, opcionalmente, matérias-primas compatíveis de isocianato; e b) uma composição de pré-mistura de poliol compreendendo um agente de sopro olefínico halogenado, um poliol, um tensioativo, e um catalisador, em que o catalisador compreende imidazol substituído tendo substituições c2 ou superiores no nitrogênio n1 e/ou seus derivados. as espumas de poliuretano ou poliisocianurato resultantes têm estrutura celular uniforme com pouco ou nenhum colapso da espuma.
