Problems solved by technology

At the same time, it is generally believed that bisphenol A epoxy resin is non-degradable, so the large-scale use of epoxy resin causes environmental pollution to a certain extent; it also limits its application in the field of biomedical adhesives with good development prospects. application

Embodiment 1

[0021] First will be as figure 1 The L-tyrosine shown in the structural formula was refluxed in ethylene glycol for more than 20 hours, and recrystallized three times with ethanol to obtain a white powder. The chemical structure was characterized by FTIR and NMR respectively. The test results showed that the synthesized figure 2 The biphenol structure shown.

[0022] The above biphenol, epichlorohydrin, K 2 CO 3 Put it into the reaction vessel according to the ratio of substances of 1:10:2, stir and mix, raise the temperature to 110°C, and continue the reaction for 3h. After the reaction, use KCl, KHCO 3 Filter the filter cake, then rinse the filter cake with a small amount of epichlorohydrin, combine the filtrate and washing liquid, distill under reduced pressure, add 50ml toluene and continue the distillation under reduced pressure, to remove residual epichlorohydrin, and distill the light yellow resinous substance at the bottom That is the product. Its structural form...

[0025] Example 2: L-tyrosine was refluxed in ethylene glycol for more than 20 hours, and recrystallized 3 times with ethanol to obtain a white powder. Its chemical structure was characterized by FTIR and NMR respectively. The test results showed that the synthesized figure 2 The biphenol structure shown.

[0026] 0.3mol of the above biphenol, 3mol epichlorohydrin, 0.6mol K 2 CO 3 Put it into a reaction container, stir and mix, raise the temperature to 110°C, and continue the reaction for 3h. After the reaction, use KCl, KHCO 3 Filter the filter cake, then rinse the filter cake with a small amount of epichlorohydrin, combine the filtrate and washing liquid, and distill under reduced pressure, add 150ml of toluene to continue vacuum distillation to remove residual epichlorohydrin, and distill the light yellow resinous substance at the bottom That is the product. Its structural formula is as image 3 shown.

[0027] Compared with the traditional bisphenol A type epoxy resi...

Abstract

The invention discloses an amino-acid-derived epoxy resin, of which the structural formula is shown in the specification. The invention also discloses a preparation method of the amino-acid-derived epoxy resin. The epoxy resin synthesized in the invention is derived from amino acids, has the characteristics of no toxicity, good biocompatibility and the like, and can be further subjected to application study in the biomedical field; at the same time, amide six-membered ring with an epoxy structure easily forms a hydrogen bond, thereby improving heat resistance and rigidity of the resin; and the epoxy resin can also be subjected to application study in the fields of high-temperature adhesives and heat-resistant adhesives.

Description

technical field [0001] The invention relates to a novel epoxy resin-amino acid derived epoxy resin, which belongs to the technical field of chemical industry. Background technique [0002] Epoxy resin refers to the general term for compounds that contain two or more epoxy groups in a molecular structure and can form a three-dimensional crosslinked cured product under appropriate chemical reagents and conditions. Epoxy resin is widely used in coatings, bonding and other engineering fields because of its excellent mechanical properties, good bonding performance to various substrates, and minimal curing shrinkage. One of the most widely used when the number of bisphenol A (BPA) epoxy resin. Bisphenol A epoxy resin is a polymer compound containing epoxy groups, ether bonds, and multiple hydroxyl groups. Because the aromatic structure of bisphenol A can significantly improve the mechanical properties and rigidity of related polymers, it is extremely preferred for the synthesis o...
