Example Embodiment

[0040] Example 1

[0041] Under the protection of nitrogen, fully mix 100 parts by weight of 2,5-furandicarboxylic acid, 1000 parts by weight of epichlorohydrin and 10 parts by weight of tetrabutylammonium bromide, react at 100°C for 1.5h, and then lower the temperature 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 is lowered to an ambient temperature of 25°C, 150 parts by weight of deionized water are added each time for washing, a total of 3 washings, and then the solvent is removed with a rotary evaporator, and vacuum dried at 50°C for 12 hours to obtain a 2,5-furan 165 parts by weight of formic acid epoxy resin.

[0042] The 2,5-furandicarboxylic acid-based epoxy resin prepared above was structurally characterized, 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...
