Preparation method of high-strength thermosetting resin hydrogel material

The invention belongs to the field of processing methods and functional application of high-performance thermosetting resins, and discloses a preparation method of a high-strength thermosetting resin hydrogel material. According to the preparation method, crosslinking is performed at medium and low temperatures under the catalysis of a high-activity catalyst to obtain organic solvent gel, and solvent replacement isperformed to obtain the thermosetting resin hydrogel, and therefore, the processing manufacturability of benzoxazine resin can be improved, the mechanical strength of the hydrogel material can be improved; and the prepared thermosetting resin hydrogel has characteristics of high mechanical strength and high toughness, and can be used as a novel high-performance resin matrix used in the water environment, and meets the use requirements of a high-strength structural material and a structure-function integrated material suitable for a water environment and a wet environment are met. 本发明涉及高性能热固性树脂的加工方法及
