Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a solid material that can be used for medical moxibustion, hot compresses, body warmers, etc., for keeping the body warm, warming food and drinks, heating, etc. The present invention relates to a heat generating composition and a method for producing the same.

PRIOR ART A heat-generating composition that generates heat in the presence of air includes a metal powder such as iron powder, a reaction aid consisting of a metal chloride (NaC, Kcll, etc.) or a metal sulfate (K2SO4, Na25O+, etc.), Water and moisturizers that absorb water well (silica gel,
(wood flour, activated carbon, etc.) are used in body warmers, hot compresses, etc.

However, since all conventional heat generating compositions are made of finely powdered metal, their packaging and storage are carried out using a laminated material of woven or non-woven fabric and a resin film with ventilation holes on the entire surface or one side. Currently, it is placed in an inner bag, sealed and stored in an outer bag made of non-breathable resin film 12 to avoid contact with air, and then taken out and used when used. (Tokuko Sho 57-26704, Jitsugoku Sho 57
(Refer to 14814) Therefore, the known charged exothermic composition requires a lot of time and effort to package the fine powder, and the production speed is slow.
It's not a scam that increases costs, but the bag's r: Accidents such as leakage of powder due to poor fitting, and furthermore, because it is a bag-shaped packaging,
It has drawbacks such as being bulky and inconvenient to handle.

Purpose of the Invention The present invention improves the drawbacks of conventional products as described above, and provides a heat generating composition that is solid and does not use a bag with ventilation holes, and a method for producing the same. .

Structure of the Invention The solid exothermic composition of the present invention is made by combining a powdered exothermic composition with a binder by compression molding.

That is, iron powder, activated carbon, NaC, f? , a powdery exothermic composition, such as a mixture with water, is mixed with a binder and compression molded to obtain an isomorphic composition. After compression molding, the solid exothermic composition is packaged to suit the intended use. That is,
A solid heat-generating composition formed into a cylinder, a plate, etc. may be tightly wrapped or glued on its outer surface with an air-permeable material such as paper, woven fabric, or non-woven fabric to prevent contact with air through the material. or wrapped with a non-breathable resin film such as PET] to be packaged with that surface sealed from air.

The form of the packaging can vary depending on the purpose of use and the desired exothermic temperature. For example, in the case of the cylindrical body of No. 11-1, the entire surface may be glued with breathable paper, woven fabric, or non-woven fabric, double-sided adhesive tape may be applied only to the top surface, and the entire body may be sealed in a non-breathable bag. However, an alternative method is to use a 4:'F combination of a breathable material and a non-breathable tape to adhere only the top surface, and glue all other surfaces with non-breathable material. , Paste double-sided adhesive tape on the bottom side opposite to the tape, and when using it, you can also remove the non-breathable tape and use it.In addition, when using it according to the body's skin, such as a warmer or hot compress. For this purpose, a soft woven fabric such as flannel or non-woven fabric may be adhered to the surface that comes into contact with the body.

In conventional bag-shaped heating yarn compositions, the shape, size, and number of ventilation holes in the bag material were changed depending on the desired temperature and heating time. In the present invention, depending on which side of the solid heat-generating composition a breathable material such as paper, woven fabric, or non-woven fabric and a non-breathable material such as a resin film are adhered to,
Although the degree of contact between air and the exothermic composition can be adjusted, in the present invention, the solidification of the exothermic composition can be controlled by adjusting the type of binder, the mixing ratio of the binder, and the compression molding force. Since the degree of contact with air can be adjusted, the desired heating temperature and heating time can be adjusted much more delicately than conventional products, depending on the purpose.

The binder used in the present invention is not particularly limited, and C
Common binders such as MC, alumina sol, gum arabic, starch, colloidal silica, and starch polyacrylate can be used singly or in combination of 26H or more. The type and mixing ratio of the binder are changed as appropriate depending on conditions such as the desired exothermic temperature, but generally about 0.5 to 3 wt% of the binder is used.

Compression molding is sufficient to sufficiently solidify the powder mixture, but it is usually in the range of 8D [1 to 30DC1kg/-,
Note that the appropriate water storage capacity of the solid body varies from about 5 to 25%, depending on the type of binder.
