Description

Heat-conducting flame-retardant protection pad for Mongolian medical tea wine therapy and preparation method thereof Technical Field The invention relates to the technical field of medical equipment, in particular to a heat-conducting flame-retardant protection pad for Mongolian medical tea wine therapy and a preparation method thereof. Background The Mongolian medical tea wine therapy is a traditional hot compress therapy with long history, and uses thermal factors generated by brick tea and wine (or alcohol) to act on the local part of a human body so as to achieve the effects of relieving pain and swelling, warming channels and dispelling cold and recovering body functions. The method is suitable for various cold diseases, such as cervical spondylosis, lumbago, leg pain, arthritis, etc. In the traditional therapy operation, the soaked brick tea is placed on the surface of a medicine pad applied to an affected part of a body surface, alcohol is sprayed to ignite the brick tea, and heat generated by combustion is used for treatment. However, when the method is applied to the scenes of Mongolian medical tea wine therapy, which need specific temperature and long-time thermal contact, obvious defects still exist. Firstly, the common single-layer cotton pad or towel has poor heat preservation performance and quick heat dissipation, so that the temperature cannot be durable and needs to be frequently replaced, the treatment continuity is broken, and secondly, some electric heating pads adopting electric heating wires can provide continuous heat sources, but have the problems of poor heat conduction performance and non-uniformity. CN111703148a discloses a silicon-based composite material heat insulating pad, which comprises a continuous phase fiber cloth substrate and a filling phase silicon-based heat insulating material, wherein the fiber cloth substrate is 1-5 layers, and the silicon-based heat insulating material comprises the following components, by weight, 15-20 parts of fiber cotton, 120-180 parts of vitrified microbeads, 5-10 parts of floating beads, 5-10 parts of attapulgite hydrosol and 5-8 parts of silica hydrosol. The invention smears the silicon-based heat insulating material on the fiber cloth base material to prepare the heat insulating pad of the composite material, in the heat insulating pad, the fiber cloth is used as a continuous phase to play a role in enhancing the mechanical strength, and the silicon-based heat insulating material plays a role in heat insulation, so that the heat insulating pad has the characteristics of high heat insulating performance and high strength. It can be seen that the technical scheme does not consider the multilayer cooperative structural design to influence the heat conduction performance and does not consider the influence of the thickness on the heat conduction stability, so that the problem of poor preparation efficiency of the heat conduction flame retardant protection pad is caused.

In order to achieve the above purpose, the invention provides a heat-conducting flame-retardant protection pad for Mongolian medical tea wine therapy and a preparation method thereof, comprising the following steps: The contact layer is obtained by carrying out surface activation on ceramic fiber cloth and coating and curing medical silica gel; carrying out hot-pressing compounding on the graphene film and the metal nanofiber felt to obtain a heat conduction layer; the heat conduction layer is arranged between the contact layer and the heat insulation flame-retardant layer to form a composite layer, wherein the contact layer is arranged on one side of the heat conduction layer, and the heat insulation flame-retardant layer is arranged on one side of the heat conduction layer far away from the contact layer; under the vacuum condition, hot-pressing the composite layer at a preset hot-pressing temperature and a preset hot-pressing pressure to obtain a protection pad blank, and after cooling, collecting the thickness of each measuring point of the center point and the four corners of the protection pad blank to obtain a thickness uniform representation value of the protection pad blank; When the thickness uniformity characterization value is larger than or equal to a first preset thickness uniformity threshold value and smaller than a second preset thickness uniformity threshold value, seconda
