酚醛树脂改性聚氨酯硬质泡沫塑料的研究

The Research of Resol Modified Polyurethane Rigid Foam

在多元醇中掺入甲阶酚醛树脂 ,与异氰酸酯反应 ,可以获得具有 PF阻燃性和 PU绝热性能的 PF/ PU共聚硬质泡沫塑料。介绍了甲阶酚醛树脂制备方法 ,并对其合成工艺、反应条件控制等进行了较详尽的探讨。

The PF/PU copolymer rigid foam was prepared from resol,polyol,isosyanates.The processing conditions of resol were researched.Flame retardancy and athemancy of product were characterized.
