木质素改性酚醛泡沫的研究

Research on Lignin-modified Phenolic Foam

酚醛泡沫是一种新兴的保温绝热材料,被称为第三代新兴保温材料,是目前泡沫保温材料中发展最快的品种。本文介绍了利用价廉、可再生的木质素代替不可再生且有毒的苯酚制取木质素改性酚醛泡沫。结果表明:木质素改性酚醛泡沫具有良好的难燃性和保温性,性能完全达到国家标准,可以用于外墙保温。

Phenolic foam was a new type of thermal insulation material,which was considered as emerging third generation of thermal insulation material.Low cost and reproducible lignin could be used to replace non-reproducible and noxious phenol in the production of lignin-modified phenolic foam.The results showed that lignin-modified phenolic foam had good heat preservation and fire resistance,and the performance of the foam reached to the national standards and can be used in external wall insulation.
