Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compositions for use in heating or igniting smoking agents. More particularly, the present invention relates to a chemical exothermic composition comprising a permanganate and an oxidizable substance that exhibits an exothermic effect when brought into contact with the permanganate.

Conventionally, various methods of heating or igniting smoking agents have been devised. Typical methods include combustion agents,
A method of igniting an igniter made of an oxidizing agent, etc. with a flame such as a stick, and using the combustion heat to burn or decompose the smoking agent, a method of adding water to calcium oxide and utilizing the heat generated at that time, and a method of using iron powder. Methods that utilize the heat of oxidation reaction in air, and methods that heat by electricity or combustion of solid alcohol fuel have been devised and used.

However, the method of igniting the igniter or fuel with a flame such as a pine tree has the problem of using an open flame or generating smoke from the igniter. In the method of adding water to calcium oxide or the method of utilizing the oxidation heat of iron powder, it is necessary to prevent moisture in the former method, and completely cut off contact with air in the latter method before the manufacturing process and use. For this reason, there were many problems such as the need to use a special container, resulting in high costs.

In addition, the electric method requires a place where electricity is available for heating, and has the drawbacks that the place where it can be used is limited, and the structure is complicated and expensive.

The inventors of the present invention have made extensive studies to solve these drawbacks, and as a result, have found a new heating additive for smoking agents to eliminate these drawbacks, and have completed the present invention.

. According to the present invention, there is provided a heating igniter for a smoking agent, which comprises a permanganate and an easily oxidizable substance that exhibits exothermic action when brought into contact with the permanganate.

1'' As the permanganate used in the present invention, potassium permanganate, sodium permanganate, calcium permanganate, magnesium permanganate, etc. can be used, or a mixture thereof may be used. Further, these can be used in granular, powder, or block form. In addition, as necessary, sodium peroxide, barium peroxide, calcium oxide, chromic acid, potassium chromate, sodium chromate, potassium dichromate, sodium dichromate, ammonium dichromate, salsa powder, sodium chlorite, peroxide, etc. Oxidizing agents such as barium chlorate, lime nitrate, ammonium nitrate, barium nitrate, etc. can be added. Furthermore, it is also possible to add metal powders such as iron, copper, aluminum, and magnesium, and inorganic minerals such as diatomaceous earth, talc, clay, bentonite, and kaolin.

The easily oxidizable substance used in the present invention may be any substance that generates heat when brought into contact with permanganate,
For example, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, polyethylene glycol, glycerol, pentaerythritol, sorbitol, hexalene gellicol, 1,3-butanediol, 1,4-butanediol, 3-methylpentane-1,3, 5-) Polyhydric alcohol such as lyol,
Amines such as tri-n-octylamine and 2-ethylhexyloxypropylamine, n-hexylaldehyde,
Examples include aldehydes such as butyraldehyde, and carboxylic acids such as propionic acid and sebacic acid.

'The amount of the easily oxidizable substance used in the present invention is 20 parts by weight or more, preferably 20 to 80 parts by weight, based on 100 parts by weight of permanganate. If it is less than 20 parts by weight, the exothermic temperature will be low, and if it exceeds 80 parts by weight, the exothermic temperature will hardly change.

The heating igniter of the present invention is one in which a permanganate and an easily oxidizable substance are stored in separate containers, and heat is generated by mixing the two at the time of use. Therefore, before use, the permanganate and the easily oxidizable substance may be stored in any manner as long as they do not come into contact with each other. For example, the permanganate and the easily oxidizable material may be stored in two separate compartments, with the partition removed during use, or the permanganate and the easily oxidizable material They may be stored in separate containers, and both may be opened and mixed at the time of use. 'The heating and igniting agent for smoking agents of the present invention is characterized by the fact that it can be heated or ignited at a desired temperature depending on the type and purpose of the smoking agent, and is extremely safe without producing flames. It is at the point where it generates heat. Furthermore, the heating igniter of the present invention has excellent stability over time, and does not require packaging conditions such as complete sealing, which is required when calcium oxide or iron powder is used.
