Abstract

The invention relates to a self-heating hot compress material and a preparation method thereof, and belongs to the technical field of composite materials. The preparation method for the self-heating hot compress material comprises the following steps: first, synthesizing magnetic nano resin microspheres with core-shell structures by adopting a high-temperature hydrothermal method; carbonizing the magnetic nano resin microspheres at a high temperature to prepare hollow porous magnetic nano carbon spheres; mechanically co-mixing the hollow porous magnetic nano carbon spheres, reduced iron powder, guhai refined haloid salts, water, carboxymethyl cellulose, rhizoma acori graminei and wormwood, thereby preparing the self-heating hot compress material. The self-heating hot compress material can start heating within one minute, the average heating temperature can be 70 DEG C or higher, the heating lasting time is long, and the heating-effect time at a temperature of 50 DEG C or higher can last for 4 hours. Besides, the self-heating hot compress material is safe and non-toxic, is easy to package, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a self-heating hot compress material and a preparation method thereof. Background technique [0002] With the development of modern technology and the improvement of human living standards, the application of heating materials has gradually shifted from the initial purpose of heating to the purpose of disease treatment and leisure health. For this reason, portable, self-heating heat preservation and hot compress materials have been paid more and more attention to, and are widely used in heating, clinical treatment, physical therapy, health care, tourism, family leisure, etc., and are common supplies in modern life. Good disposable self-heating materials are what researchers working in medical devices and physical therapy and health care have been trying to find. At present, many self-heating material research reports use aluminum powder, iron powder, wate...
