摘要
以环氧大豆油(e SBO)和二氧化碳为原料合成五元环碳酸酯,然后与胺反应制备非异氰酸酯聚氨酯(NIPU)。通过环氧值测定、红外光谱分析考察了反应时间对合成环碳酸酯的影响,并研究了环氧大豆油的不同转化率、胺固化基团摩尔比对环碳酸酯胺固化合成的NIPU的综合力学性能的影响。研究结果表明,随着反应时间的延长,环氧大豆油的转化率不断提高,当环氧大豆油的环氧基转化率达到99.8%时反应需要进行40 h;并且随着e SBO转化率的提高,合成的NIPU的机械性能越来越好;胺用量的增加有利于环碳酸酯转化成氨基甲酸酯,当环碳酸酯与胺的基团摩尔比为1∶1时合成的NIPU综合机械性能最佳。
Epoxidized soybean oil(ESBO) and carbon dioxide were employed as raw materials to synthesize fivenumbered cyclic carbonates.The obtained cyclic carbonates were further reacted with amine to produce nonisocyanate polyurethane(NIPU).By means of measurement of epoxy value and FT-IR analysis,the influence of reaction time on the synthesis of carbonated soybean oil(CSBO) was investigated.The results showed that the ESBO conversion increased when the reaction time was prolonged.When the reaction lasted for 40 hours,the ESBO conversion reached to 99.8%.With the increase of ESBO conversion,the mechanical properties of NIPU were improved.An increase in the amount of amine was conducive for cyclic carbonates transforming into carbamate and NIPU exhibited the best mechanical properties with the equivalent ratio of carbonate and amine reaching to 1:1.
