| titleOfInvention | Preparation method of full-bio-based epoxy resin of double-crosslinking system |
| abstract | The invention discloses a preparation method of full-bio-based epoxy resin of a double cross-linking system, belonging to the technical field of sustainable development of high polymer materials, comprising the steps of dissolving chitosan in dilute acid solution, and mechanically stirring to prepare high-viscosity solution; adding CaSO to the high viscosity solution 4 Or the hydroxyapatite is coordinated and crosslinked to form a complex, and mechanical stirring is carried out to prepare a solution with a first heavy crosslinked network; adding nanocellulose into the solution with the first re-crosslinked network, and performing ultrasonic dispersion to prepare a mixed solution; preparing the resin from the mixed solution. The invention achieves the technical effects of enhancing the toughness and mechanical strength of the resin, facilitating environmental protection of materials adopted in the preparation process and simplifying the preparation method. |
