The present invention relates to a high-strength and tough nanocomposite hydrogel and a preparation method thereof, which belongs to the technical field of hydrogel preparation and solves the problem that the existing hydrogel cannot have both high water content and high toughness. The hydrogel contains polymers and two-dimensional nanosheets, the polymers are distributed in any area in the hydrogel, and the two-dimensional nanosheets are oriented and arranged in the hydrogel; wherein a nano-confined space is formed between adjacent two-dimensional nanosheets, and a layered PVA crystal region is contained in the nano-confined space. The preparation of a hydrogel with both high water content and high mechanical properties is achieved.

Aiming at the problem that the cell walls of the rhizome traditional Chinese medicinal materials are tough, the rhizome traditional Chinese medicinal materials are moistened by saturated steam after being subjected to negative pressure treatment, so that the medicinal materials become soft and easy to cut, the cell wall permeability of the rhizome traditional Chinese medicinal materials is improved, and the processing full degree is improved; a 20-40% ethanol water solution is adopted for full infiltration and pressurization to 5-8 atm, and then rapid pressure relief is conducted, so that the cell structure is fully destroyed, and the leaching rate of medicinal components is increased. In order to solve the problem that heavy metals are easy to accumulate in the planting process of traditional Chinese medicinal materials, a roughly filtered extracting solution is adsorbed by using chelating macroporous resin, so that the traditional Chinese medicinal extract does not contain or only contains extremely low heavy metals. According to the method, microfiltration, ultrafiltration and macroporous resin adsorption are sequentially used, so that the content of impurities such as pigment, tannin and protein in the traditional Chinese medicine extract powder is reduced, and the quality grade and safety of the traditional Chinese medicine extract are ensured.
