Abstract

POLIURETANOS CURADOS COM AMINAS E SUA PREPARAçãO. Descrevem-se pré-polímeros de poliuretano que são preparados a partir de 2,4'-diisocianato de difenilmetano (2,4'-MDI), um componente de poliol e um diisocianato alifátiço. Esses pré-polímeros podem ser curados com aminas alifáticas, cicloalifáticas e/ou aromáticas para formar um elastómero de uretano elastomer. Em comparação com elastómeros de uretano curados à base de 2,4'-MDI monomérico, esses pré-polímeros proporcionam elastómeros com prazo de validade de vazamento prolongado, isto é, exibem uma taxa mais lenta de acúmulo de viscosidade depois que o agente de cura e pré-polímero são misturados, o que resulta em uma propensão reduzir a rachar durante o processo de cura e dá oportunidade de moldar por vazamento peças maiores. Em comparação com poliuréialuretanos preparados a partir de pré-polímeros de TDI e que opcionalmente incluem H12-MDI, os pré-polímeros da invenção têm melhores aspectos para a saúde e segurança.
