摘要
松香是我国林产化工行业最重要的产品,年产量70万吨,居世界第一位。它具有稠合多脂环刚性结构,刚性大、耐热性好,如果把它引入到多元醇中,势必对其刚性、光泽、耐热性等性能产生影响,进而提高由其合成的聚氨酯树脂等材料的性能。本文就松香基多元醇的合成及其应用作一概述。
With more than 700 kt/a of output, rosin is the most important product of forest chemicals in our country, which takes the first place in the world. Due to fused polycyclic skeleton in molecular structure, rosin has good rigidity and heat resistance.Introduction of rosin to polyols could improve the rigidity, gloss and heat resistance of the polyols and the derived polyurethane.In this paper, the synthesis and application of rosin-based polyols are summarized.
