COMPOSITION FOR FAR INFRARED RADIATION AND ELECTROMAGNETIC WAVE BLOCKING

摘要

PURPOSE: Provided is a composition for a large quantity of far infrared radiation at body temperature or room temperature and electromagnetic wave blocking, which is adaptable personal accessories in a low price. CONSTITUTION: The composition preparation is prepared by the following steps: mixing 70wt.% of fine clay powder(1.1-10 micrometer) obtained by heating to 1300°C with 30% of ferrite powder, where the clay powder contains germanium, alumina and zirconia as main materials; melting in high heated furnace; molding or extruding for solid products. The other composition is prepared by coating the surface of products with a mixture of the clay and ferrite powder, and urethane or acryl-based resin.
