The present invention discloses a biomass-based epoxy resin and preparation method thereof; under conditions of N,N-dimethylformamide as a catalyst, 2,5-furandicarboxylic acid and thionyl chloride are acylated to obtain 2,5-furan diformyl chloride; then it is dissolved with dichloromethane; under tertiary amine conditions an esterification reaction takes place, and bis(4-allyl-2-methoxyphenyl)furan-2,5-dicarboxylic acid ester is thus obtained; by means of meta-chloroperoxybenzoic acid, its unsaturated double bond is epoxidized to obtain a biomass-based epoxy resin. The process of the present invention is simple; the raw materials come from biomass 2,5-furandicarboxylic acid and eugenol; in comparison with bisphenol-A epoxy resin based on petroleum and coal resources, the raw materials are green and renewable, and are advantageous to reducing the consumption of renewable resources with regard to polymeric material. The obtained cured epoxy resin has excellent thermal properties and modulus, and has broad prospects for application.
本发明公开了一种生物质基环氧树脂及其制备方法;在N,N-二甲基甲酰胺作为催化剂的条件下,2,5-呋喃二甲酸和亚硫酰氯酰化得到2,5-呋喃二酰氯,然后用二氯甲烷溶解;在叔胺条件下发生酯化反应,得到双(4-烯丙基-2-甲氧基苯基)呋喃-2,5-二羧酸酯;用偏氯过氧苯甲酸将其不饱和双键环氧化,得到生物质基环氧树脂。本发明工艺简单,原料来源于生物质 2,5-呋喃二甲酸和丁香酚,与基于石油和煤炭资源的双酚 A 环氧树脂相比,原料绿色可再生,有利于减少高分子材料对可再生资源的消耗。所得固化环氧树脂具有优异的热性能和模量,应用前景广阔。
