Abstract

The invention discloses a far infrared heat-radiation ceramic slurry, the far infrared heat-radiation ceramic slurry is prepared by mixing a ceramic powder precursor with a corresponding solvent, a bonding agent, a dispersing agent or a structure modification agent, and the ceramic powder precursor is selected from a composition of salts or oxides of Na, Mg, Ca, B, Al, C, Si, Sn, Mn, Fe, Co, Ni and Cu. A functional ceramic body is obtained by coating the far infrared heat-radiation ceramic slurry on the surface of a substrate or adding the far infrared heat-radiation ceramic slurry into a polymer material, and then heating for drying. The functional ceramic body is a composition or a derivative with at least one or more than one structure of feldspar, olivine, cordierite, chlorite, green magnesium nickel ore, tourmaline, tremolite, actinolite, serpentine, spinel or calcite, has the far infrared radiation rate reaching 0.90-0.98, can rapidly transfer heat energy into radiation waves for spreading to the outside so as to achieve a rapid heat-radiation effect.

Description

technical field [0001] The invention relates to a ceramic slurry, a fiber cloth prepared by using the slurry, a film prepared by using the slurry and a preparation method, in particular to a slurry with far-infrared heat dissipation effect, and a fiber cloth prepared by using the slurry , The film prepared by using the slurry and the preparation method. Background technique [0002] With technological innovation, single-functional electronic products can no longer meet the needs of users, and multi-functional electronic products have been developed with each passing day, such as: game consoles, smart phones, tablet computers, flat-panel displays, and digital cameras. [0003] With this multi-functional product type, the placement ratio and performance requirements of various chips continue to rise, and how to effectively dissipate heat from various components has become a very important issue. If the heat cannot be effectively transferred to the outside world, it will not o...
