Self-heating agent for article heating and self-heating agent package

Abstract

The invention relates to a self-heating agent for article heating and a self-heating agent package. The self-heating agent consists of a component A and water, wherein the component A consists of 10 parts by weight of calcium oxide, 3-10 parts by weight of anhydrous magnesium sulfate and 1-20 parts by weight of auxiliary materials, and the ratio of the component A to water is 1:(1-3.5). Even if the self-heating agent disclosed by the invention is arranged in a closed container or package, an explosion hazard is avoided, and the safety is high. The self-heating agent package disclosed by the invention comprises a self-heating agent packaging bag, a first space, a second space and a separator, wherein the first space is formed in the self-heating agent packaging bag and is used for containing water; the second space is formed in the self-heating agent packaging bag and is used for containing the self-heating agent for article heating disclosed by the invention; and the separator is arranged between the first space and the second space and is used for separating from or communicating with the first space and the second space when needed. The self-heating agent for article heating and the self-heating agent package disclosed by the invention are low in cost, good in effect, convenient to use, safe, environment-friendly and easy to popularize.

Description
