The hydrophilic fiber layers are positioned on the upper side and the lower side of the heating material layer and wrap the heating material layer; the hydrophilic fiber and the superfine fiber play a role of a framework in the invention, and keep the shape of the heating patch.
And the breathable film layer is positioned on the upper layer of the hydrophilic fiber layer on the upper side. Oxygen in the air enters the heating material layer through the breathable film layer.
And the non-breathable film layer is positioned below the hydrophilic fiber layer on the lower side.
Further, the active agent is any one of alkylphenol ethoxylates, glyceryl monostearate and polysorbate.
Further, the heating material layer is prepared from the following raw materials in percentage by weight: 50% of reduced iron powder, 11.6% of activated carbon, 8% of vermiculite, 27% of water, 2% of salt, 0.3% of polysorbate, 0.1% of superfine fiber and 1% of water-absorbent resin.
Further, the hydrophilic fiber layers are multiple, heating material layers are distributed between every two adjacent hydrophilic fiber layers, the number of layers of different heating materials can be adjusted according to different product requirements, and due to the stable structure of the heating material layers, the heating materials are uniformly distributed between the two adjacent hydrophilic fiber layers, and even if the heating material layers are thick, the raw materials can fully react with oxygen.
Further, the heating material layers are evenly spread on two adjacent hydrophilic fiber layers to form a whole heating sheet, or the heating material layers are formed by a plurality of blocks, and the plurality of heating material layers are evenly distributed on the two adjacent hydrophilic fiber layers at intervals to form dot-shaped cuttable heating sheets. Different heating paste shapes can be trimmed according to the use scene, and the heating paste is more attached to a human body, so that the heating paste is suitable for more warm-keeping scenes.
Further, a plurality of grooves are pressed on the surface of the heating sheet, the grooves are used for bending the heating sheet, and the angle of the heating sheet is adjusted according to the human body curve; when the heating sheet is a cutting type heating sheet, the lower surface of the heating sheet is in a state that a plurality of bulges are uniformly distributed.
Further, the grooves are linear grooves, and the grooves are linear or arc-shaped. Different linear combinations can be pressed according to different warmth retention parts.
Further, the plurality of protrusions are semicircular protrusions or square protrusions; when the massage device is in a semicircular bulge, the massage effect is achieved.
The preparation method of the sheet heating patch is characterized by comprising the following steps of:
step one: the active agent and the salt are mixed and then dissolved in water to prepare a mixed solution.
Step two: and uniformly stirring the reduced iron powder, the vermiculite, the activated carbon, the water-absorbent resin and the superfine fibers, and adding the mixture to form the heating material.
Step three: uniformly spreading the heating material on the hydrophilic fiber layer to form a heating material layer, covering the hydrophilic fiber layer on the upper part of the heating material layer again to enable the hydrophilic fiber layer to fully wrap the heating material layer to form a whole heating sheet, or uniformly distributing the heating material on the hydrophilic fiber layer at intervals to form a plurality of heating material layers on two adjacent hydrophilic fiber layers to form a dot-shaped cuttable heating sheet, wherein the intervals between the plurality of heating material layers are 1cm.
Step four: and applying pressure to the heating sheet, sealing edges of the heating sheet, extruding grooves on the heating sheet, and pressing the heating sheet into a convex state by a plurality of heating material layers when the cutting type heating sheet is pressed, wherein the pressing is performed between adjacent hydrophilic fiber layers, so that the lower surface of the heating sheet is in a convex uniform distribution state.
