Abstract

The invention provides a self-heating heating bag and a preparation method thereof. The self-heating heating bag consists of content and a bag body, wherein the content is sealed inside the bag body; and the content contains iron powder, deionized water, activated carbon, vermiculite, sodium chloride, and a water-absorbing resin. The self-heating heating bag can quickly increase the temperature after the unsealing, and has steady heating temperature and permanent heating time; and the self-heating heating bag adopts environment-friendly and safe raw materials, has no toxicity, and can be safely used for human bodies.

Description

technical field [0001] The invention belongs to the field of generation or utilization of non-combustion heat, in particular to a self-heating heating bag and a preparation method thereof. Background technique [0002] With the advent of winter, the weak and the old and young people have poor resistance to cold, especially the joints, waist and abdomen of the body. The local cold will not only bring discomfort to people, but also cause some diseases. For this reason, these people have reduced their outdoor activities in winter, which not only affects travel, but is also not conducive to their health. The existing local heat preservation products on the market include traditional hot water bags, heaters, "reboots" with heat-generating sheets in the inner bag that have appeared in recent years, and "warm treasures" that need to be charged by themselves. The above-mentioned products all have the disadvantages of being inconvenient to carry and use, while similar products that ...
