The technical proposal is further improved that the high-viscosity metal resin is bisphenol A epoxy resin.
The technical proposal is further improved that the glass transition temperature of the high-viscosity metal resin is 70-85 ℃, the softening point is 90-100 ℃, the molecular weight is 30000-41000, and the hydroxyl value is 4-5 mgKOH/g.
The technical proposal is further improved that the preparation method of the surface modified nano far infrared ceramic powder comprises the following steps: dissolving a coupling agent in the solution, performing ultrasonic dispersion for 10min, adjusting the pH value to 5-6, adding 10-25g of dried nano far-infrared ceramic powder after stirring for stabilization, performing ultrasonic dispersion for 20min, performing water bath at 65 ℃ for 20min, and finally drying, cooling and grinding the mixed solution to obtain the surface modified nano far-infrared ceramic powder.

The technical proposal is further improved in that the permanent magnetic material powder is neodymium iron boron powder.
The technical proposal is further improved in that the auxiliary agent comprises one or a mixture of two of an ultraviolet absorbent, an antioxidant and a crosslinking agent.
A preparation method of a hot melt adhesive film with high viscous metal force comprises the following steps:

and S3, placing the hot melt adhesive particles in a film making forming machine to prepare the high-viscosity metal hot melt adhesive film.
The invention has the beneficial effects that:
1. the invention adopts bisphenol A type epoxy resin as the high-viscosity metal resin. Bisphenol A epoxy resin is a high molecular compound prepared by condensing bisphenol A and epichlorohydrin under an alkaline condition, washing with water, and removing a solvent.
