Abstract

um sistema de reação para a formação de uma espuma de poliuretano inclui um componente isocianato que tem pelo menos um componente isocianato e um componente reativo com isocianato que é uma mistura formada por adição de pelo menos um componente poliol, um componente aditivo, e uma dispersão aquosa de polímero pré-formado. a mistura inclui, baseado no peso total da mistura, de 50,0% em peso a 99,8% em peso de um componente poliol incluindo, pelo menos, um poliéter poliol, a partir de 0,1% em peso a 50,0% em peso de um componente aditivo que compreende pelo menos um catalisador, e de 0,1% em peso a 6,0% em peso de uma dispersão aquosa de polímero pré-formado. a dispersão aquosa de polímero pré-formado tem um teor de sólidos de 10% em peso a 80% em peso, com base no peso total da dispersão aquosa de polímero pré-formado, e é uma de uma dispersão aquosa de polímero ácido ou uma dispersão aquosa de polímero de poliolefina modificada com ácido em que a poliolefina é derivada de pelo menos um c2 a c20 alfa-olefina.
