Embodiment 1

[0041] Under the protection of nitrogen, 100 parts by weight of 2,5-furandicarboxylic acid, 1000 parts by weight of epichlorohydrin and 10 parts by weight of tetrabutylammonium bromide were fully mixed, reacted at 100°C for 1.5h, and then cooled to 30°C. 80 parts by weight of sodium hydroxide and 160 parts by weight of deionized water were added to form a reaction system, and the reaction was continued for 3 hours. After the reaction system was lowered to the ambient temperature of 25°C, 150 parts by weight of deionized water was added each time for washing for a total of 3 times, and then the solvent was removed with a rotary evaporator, and vacuum-dried at 50°C for 12 hours to obtain a compound based on 2,5-furan 165 parts by weight of the epoxy resin of formic acid.

[0042] The epoxy resin based on 2,5-furandicarboxylic acid prepared above is characterized by structure, and the hydrogen nuclear magnetic resonance spectrum is as follows: figure 1 shown.

Description

technical field [0001] The invention belongs to the field of thermosetting resins, and in particular relates to a 2,5-furandicarboxylic acid-based epoxy resin and a preparation method and application thereof. Background technique [0002] The latest research results show (J.Am.Chem.Soc,2009,131(5):1979-1985) that 2,5-furandicarboxylic acid can be prepared from corn and other plant stalks through a series of catalytic reactions, with high yield and low cost. Low. The preparation of 2,5-furandicarboxylic acid can use renewable resources, which has the advantages of green and environmental protection. How to apply it has become an important topic for researchers to study. [0003] At present, 2,5-furandicarboxylic acid from biological sources has been generally considered as an important bio-based platform compound, which is widely used in the synthesis of polymer materials. For example, the Chinese patent application with application number 201010244720.4 discloses a prepara...
