▎ 摘　　要

NOVELTY - Angelica dahurica bead healthcare product includes Angelica dahurica bead polished from the roots of Angelica dahurica and a protective layer coated on the surface of the Angelica dahurica bead body. The protective layer is a porous polymer composite material composed of graphene oxide modified silicon dioxide, epoxy resin, curing agent and nitrile rubber. The thickness of the protective layer is 0.5-2.0 mm. The mass ratio of epoxy resin, curing agent, nitrile rubber and graphene oxide modified silicon dioxide is 80-120:25-35:5-30:5-10. USE - Angelica dahurica bead healthcare product. ADVANTAGE - The Angelica dahurica bead healthcare product directly makes the root of Angelica dahurica into a bead body, and wraps a protective layer on its surface, and avoids the problem of excessive volatilization of the volatile oil of Angelica dahurica caused by the crushing of Angelica dahurica, and having health care functions such as relieving headaches, allergic rhinitis and preventing viruses, reduce the probability of being easily scratched or damaged due to the softness of Angelica dahurica, so that Angelica beads can be worn and used for a long time, and have a long-term and effective health care effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the Angelica dahurica bead health product, which involves removing the epidermis from the roots of Angelica dahurica to make beads and cleaning them, coupling the silica powder with a silane coupling agent, adding water to prepare a suspension, adding a graphene oxide aqueous solution to the suspension, stirring and reacting at room temperature for 1-3 hours, and then performing drying treatment to obtain graphene oxide-modified silica powder, adding the graphene oxide modified silica powder and the curing agent into the mixture of epoxy resin and nitrile rubber, and stirring uniformly to obtain the protective layer slurry, coating and solidifying the beads with the protective layer slurry to obtain a health care product of Angelica dahurica.
