Chemical heating combinations and heating bag

Abstract

The invention belongs to the heating material field and in particular discloses a chemical heating composition which comprises iron powder, bamboo carbon powder, non-sodium soluble inorganic salt, water, inorganic porous water retention agent and super absorbent resin. In air, the heating composition can be used as heating material, and wastes of the heating composition can be reused as fertilizer and soil amendments. In addition, a heating bag which is provided with double-layer structure is also disclosed by the invention. The internal layer is a permeable package bag which is full of the chemical heating composition. The external layer is non-permeable package bag. The permeable package bag of the internal layer is processed from biodegradable nonwoven fabrics and biodegradable plastics. After being abandoned, the permeable package bag of the internal layer can be biodegradable, and pollutions to the environment are avoided.

Description

technical field

[0001] The invention belongs to the field of heating materials, and in particular relates to a chemical heating composition; in addition, the invention also relates to a heating bag using the chemical heating composition. Background technique

[0002] Chinese patent CN1760310A disclosed a chemical heating material and a heating bag made of the above chemical heating material on April 19, 2006, which will be made of iron powder, activated carbon, sodium chloride, water, inorganic water retaining agent (or wood powder) ), etc., and the composition that generates heat when exposed to air is packaged in an air-permeable inner bag, and then sealed in a non-air-permeable outer bag for storage. When in use, open the outer bag and take out the inner heating bag. This kind of disposable heating bag has important applications in human body and animal heating, plant and equipment heat preservation, drug efficiency enhancement and medical care, etc., and the consumption...
