NOVELTY - A medical hot melt adhesive comprises matrix resin, tackifying resin, plasticizer, antioxidant, and graphene raw material. USE - Medical hot melt adhesive for graphene composite material. ADVANTAGE - The medical hot melt adhesive avoids unsatisfactory drug loading capacity, easy breeding of bacteria and allergy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of medical hot melt adhesive, which involves adding plasticizer and tackifying resin according to the proportion to a sealed reactor, heating under protection of nitrogen, uniformly stirring, adding matrix resin and antioxidant, and continuously stirring to form stable viscous fluid, and discharging to obtain mixture (I), crushing the graphite raw materials into small particles to prepare graphene oxide solution using purified water, adding strong acid, oxidant, and catalyst, heating in a sealed reactor under protection of nitrogen, adjusting the pH value of the reacted graphene derivative, and dehydrating to obtain mixture (II), and mixing the mixture (I) and the mixture (II).
