Definitions
- the present invention relates to an exothermic agent. More specifically, calcium oxide having a specific average particle diameter and mixed powder aluminum obtained by mixing two types of powder aluminum having different particle size distributions at a mass ratio of 1: 2 are blended at specific ratios. An exothermic agent, calcium oxide having a specific average particle size, and two types of powdered aluminum each having a different particle size distribution were mixed at a specific ratio, and each was mixed at a specific ratio.
- the present invention relates to a heat generating agent containing an inorganic salt compound as a three component.
- claim 1 of Patent Document 1 states that “the powder calcium oxide of 100 mesh (one 150 m90% or more) to 200 mesh (one 75 m95% or more) per weight of the heat generating agent is 15 to 30%. , and 330 mesh (an 45 m) force 40 to 60 0/0, + 330 mesh (+ 45 m) power 15 - 30%, + 235 mesh (+ 63 111) is 15%>, + 200 mesh (+ 75 m) Exothermic agent composed of 70-85% powdered aluminum with a particle size distribution of 0%
- aluminum powder reacts rapidly with calcium hydroxide according to the following formula (2) to generate calcium aluminate and hydrogen.
- the first point to be improved of the exothermic agent utilizing the reaction between the mixture of calcium oxide and aluminum as described in Patent Document 1 and water is to reduce the generation amount of hydrogen gas as much as possible. It is to reduce. This is the most important issue requested by users in the process of developing applications for heat-generating agents.
- the bottom area is in the range of approximately 12 cm 2 to 19 cm 2 .
- the weight of the chemical exothermic agent entering such a small area is at most 5 g to 10 g. Therefore, even if the amount of chemical exothermic agent containing calcium oxide and aluminum in a specific ratio is as small as 5g, After the reaction with water, the temperature is quickly raised to around 100 ° C to 90 ° C, then the temperature drops at a small temperature drop rate, and it remains at around 80 ° C even after 600 seconds. . In this case, it is important to control the maximum temperature so that it does not become 100 ° C so that the user will not be burned, and maintain it at around 80 ° C even after 600 seconds. It is.
- maintaining the temperature at around 80 ° C even after 600 seconds has passed means that the exothermic agent of the present invention is used in a cold environment below freezing point, such as mountaineering, fishing, outdoor shelter in the event of a large-scale disaster, and heating of combat food. It is an essential condition because it may be used below.
- the inventors first studied to increase the unit calorific value. As described above, the reaction between the exothermic agent composed of a mixture of calcium oxide and powdered aluminum and water follows the reaction formulas (1) and (2).
- reaction formula (2) aluminum reacts abruptly with the hydroxylating power produced by reaction formula (1) to generate calcium aluminate and hydrogen.
- inorganic salt and so-called hydropyrogenic agent that reacts with water such as calcium oxide and generates heat.
- Patent Document 2 discloses an exothermic agent composed of calcium oxide, an inorganic salt such as potassium carbonate, sodium carbonate, magnesium chloride, magnesium sulfate, potassium chloride, calcium hydroxide, sodium sulfate, sodium benzoate, A method for controlling the heat generation of a hydrothermal exothermic agent characterized by adding an aqueous solution containing an organic salt such as sodium dodecyl sulfate is disclosed.
- Patent Document 1 Patent No. 3467729
- Patent Document 2 Japanese Patent Laid-Open No. 2003-171658
- the problem to be solved by the invention is that a chemical pyrogen containing calcium oxide and aluminum in a specific ratio is subdivided into small volumes of food such as baby bottles, canned or bottled sake, canned coffee, canned soft drinks, and so on. It is an economical, heat-efficient and heat-generating agent that can heat so-called small-capacity foods such as shochu and meat buns to a temperature where they can be eaten in a short time.
- a more specific problem to be solved by the invention is that even if the chemical exothermic agent containing calcium oxide and aluminum in a specific ratio is as small as 5 g, the maximum temperature after reaction with water is 100 ° C. While controlling so that it does not exceed the above, quickly raise the temperature to around 100 ° C to 90 ° C, then drop the temperature at a small temperature drop rate, and maintain around 80 ° C even after 600 seconds That's it.
- the present inventors have focused particularly on the particle size distribution of powder aluminum, and mixed powder aluminum aluminum in which two types of powder aluminum each having a different particle size distribution are mixed at a mass ratio of 1: 2.
- a heat ratio of calcium oxide having a specific average particle size and calcium oxide having a specific average particle size, and two types of powdered aluminum each having a different particle size distribution in a mass ratio of 1: 2 It was discovered that exothermic agents containing the mixed powders mixed at a specific ratio and the third component can solve the above problems. Therefore, the above problems are solved by the means described in the following items.
