Embodiment 1
[0025] A medical stone health care pad, which includes an upper covering material, a medical stone filling, and a lower covering material from top to bottom, and the upper and lower covering materials are heat-sealed to seal the medical stone filling in the middle .
[0026] see figure 1 , the surface of the medical stone health care pad forms a grid shape that is not connected to each other, the upper and lower cladding materials are PVC materials, and the main component of the medical stone filling is medical stone powder.
[0027] The ingredients of the medical stone filling include medical stone powder, silica gel, negative ion powder, calcium saccharate, green mica powder, polypropylene nanofiber, potassium citrate, Sichuan Phellodendron powder, and the weight parts of the above components are medical stone powder 55- 65 parts, 20-25 parts of silica gel, 10-15 parts of negative ion powder, 2-3 parts of calcium saccharate, 1-1.5 parts of green mica powder, 5-10 parts of p...

[0030] As a further improvement, in addition to having the above-mentioned technical features, the preparation method of the medical stone health pad includes the following steps: a. Prepare the medical stone filling, and compress the mixed powder mainly composed of medical stone into the same size , the thickness of the disc; b. Place a grid mold on the table of the high-frequency heat sealing machine, spread the covering material on the upper layer of the grid mold, and place the pressed disc in the center according to the grid position; c. The disc is covered with a layer of upper coating material, and after being placed neatly, it is pressed by the head of a high-frequency heat-sealing machine. Once formed, the medical stone health care pad is obtained.
[0031] In step a, the mixed powder is pressed through a hydraulic tablet press, and the thickness of the pressed disc is 2-6mm, and the ideal thickness of the pressed disc is 4mm. Tests have shown that each raw material in...
