Natural self-heating health-care physiotherapeutic kneepad and production method thereof

[0037] Example 1:

[0038] as attached Figure 1-3 As shown, the present invention provides a natural self-heating health care knee pad, comprising a knee pad body 1 fitted with the knee area of ​​the human body, the first layer of the knee pad body 1 and the second layer fitted with the knee area of ​​the human body The third layer is spandex elastic mesh cloth, the second layer is elastic cotton cloth layer, the body of the knee pad is provided with a casing 2 with a concave cavity adapted to the shape of the knee of the human body, and the casing 2 is provided with ventilation holes 6. A buffer pad 3 is arranged in the cavity of the casing 2, a fixing band 4 is arranged on the two sides corresponding to the knee brace body 1, and the free end of the fixing band 4 is arranged with an adhesive point 5, and the buffer A number of self-heating far-infrared functional bonding particles 7 are distributed on the outer surface of the pad 3 that is attached to the human knee, and the outer surface of the spandex elastic mesh cloth of the third layer is distributed with self-heating far-infrared functional bonding particles 7, The self-heating far-infrared functional adhesive particles 7 are formed by heating and drying a self-heating far-infrared functional adhesive slurry, and the self-heating far-infrared functional adhesive slurry contains raw ore slurry and far-infrared functional additives. , adhesives and dispersants.

[0039] The present invention also provides a preparation method of natural self-heating health-care physiotherapy knee pads, comprising the following steps:

[0040] (1) Preparation of raw ore slurry: remove impurities from tourmaline raw ore by ultrasonic washing, the power of ultrasonic washing is 30-120kW, the temperature is 10-30°C, and the time is 10-90min; 5h to prepare particles of 1-3mm, and then to grind for 1-5h to prepare particles of 0.1-1mm, and finally to prepare the raw ore slurry of 1-10μm by water mill for 1-5h. The ore slurry contains 100% tourmaline slurry.

[0041] (2) Preparation of self-heating far-infrared functional adhesive slurry: put far-infrared functional auxiliary, dispersant, adhesive and raw ore slurry into the high-speed shearing machine, and fully mix through high-speed shearing to obtain self-heating far-infrared functional adhesive. Infrared functional adhesive paste. Graphene is used as the far-infrared functional auxiliary agent, sodium dodecylbenzene sulfonate is used as the dispersant, and the adhesive contains 20% water-based polyurethane, 35% acrylate and 45% silica gel. At this time, the self-heating is far away. The content of each component in the infrared functional adhesive paste is as follows: graphene accounts for 5%, sodium dodecylbenzene sulfonate accounts for 5%, adhesive accounts for 50%, and tourmaline pulp accounts for 40%.

[0042] (3) Preparation of self-heating far-infrared functional adhesive particles 7: Adhere the self-heating far-infrared functional adhesive paste to the The buffer pad 3 and the outer surface of the spandex elastic mesh cloth as the third layer are then heated and dried in an oven at 60-200°C for 10-90min or irradiated under a far-infrared lamp of 100-600W for 5-60min. The self-heating far-infrared functional adhesive slurry was heated and dried to form self-heating far-infrared functional adhesive particles 7 with a surface diameter of 1 mm.

[0043] (4) Under sterile conditions, take the spandex elastic mesh cloth of the first layer and the spandex elastic mesh cloth of the third layer obtained by step (3), and add between the first layer and the third layer as the first layer. The two-layer elastic cotton cloth layer is used to make the knee pad body 1; the middle position of the knee pad body 1 is cut out to fit the hollow part around the shell 2, and then the shell 2 is placed at the hollow part and fixed with the knee pad body 1; After placing the buffer pad 3 prepared in the step (3) in the cavity of the casing 2, sealing is performed; then the two sides corresponding to the knee pad body 1 are sewn on the fixing belt 4 to obtain a natural self-heating Health physiotherapy knee pads.

[0044] Example 2:

[0045] Different from Example 1, in step (1) of the preparation method of the present invention, the raw ore slurry contains 50% tourmaline slurry and 50% germanite slurry. In step (2), the far-infrared functional additive contains 50% graphene and 50% carbon nanotubes, the adhesive contains 40% water-based polyurethane, 25% acrylate and 35% silica gel, and the dispersant is selected Polyvinylpyrrolidone. At this time, the content of each component in the self-heating far-infrared functional adhesive slurry is: far-infrared functional auxiliary agent accounts for 10%, polyvinylpyrrolidone accounts for 5%, adhesive accounts for 50%, raw ore slurry accounts for 50% 35%.

[0046] Example 3:

[0047] Different from Example 1, in step (1) of the preparation method of the present invention, the raw ore slurry contains 25% tourmaline slurry, 25% germanium stone slurry, and 25% Bianstone slurry. and 25% silica slurry. In step (2), the far-infrared functional auxiliary agent is selected from graphene, the adhesive is selected from water-based polyurethane, and the dispersant is selected from sodium carboxymethyl cellulose. At this time, the content of each component in the self-heating far-infrared functional adhesive slurry is: graphene accounts for 0.01%, sodium carboxymethyl cellulose accounts for 4.99%, water-based polyurethane accounts for 55%, raw ore slurry accounts for 40% %.
