Spontaneous heating agent

Abstract

The invention relates to a spontaneous heating agent which comprises the following components in percentage by weight: 60% of calcium oxide, 16% of sodium carbonate, 16% of potassium carbonate and 8% of aluminum powder. The spontaneous heating agent is fast to heat, high in temperature, low in cost, and small in size, the weight of a heating packet is only 40-50g, thus being convenient to carry when people goes out; the spontaneous heating agent does not release extraneous odor and is free of environmental pollution in an exothermic reaction, and has a wide application range, can be used in various heating and disinfection fields, can facilitate the heating of food and beverages as well as the steam sterilization of a medical instrument bag, and the like.

Description

technical field [0001] The invention belongs to the technical field of rapid heating of self-heating food, in particular to a self-heating agent.
