Problems solved by technology

It is described that in order to increase the amount of tourmaline negative ions, rare earths, photocatalytic materials, etc. are added. From the perspective of adding rare earths, the prepared composite powder has a large safety hazard, and it can only increase the amount of negative ions. The effect of self-heating
Some patents add metal silver, but the purpose is not to improve the functionality of tourmaline negative ion materials

Abstract

The invention relates to a composite material with heat accumulation function, which comprises (by weight ratio) tourmaline ultramicro powder 25-50%, caloric powder 40-65%, adhesive 2-5%, embedding agent 1-5%. The process for preparation comprises raw material preparation, mixing, and press forming, wherein the pressure for press forming is 12-30 MPa.

Description

technical field [0001] The invention belongs to the field of powder products and relates to a composite material with self-heat storage function. Background technique [0002] The functional characteristic of the self-heating functional composite material is that it can release energy by itself under certain conditions, stimulate and improve the negative ion generation ability of tourmaline ultramicro bodies, and thus have multiple functions and health care functions. [0003] In recent years, the impact of negative ions and their generating materials on air quality and health has been highly valued by many scientific research institutions, experts, scholars and entrepreneurs. The amount of negative ions in the air has become the standard for whether the air is fresh or not. The World Health Organization (WHO) stipulates that the standard concentration of negative ions in the fresh air should not be less than 1000 to 1500 per cubic centimeter of air. At present, the biologi...
