Nanometer far infrared carbon-fiber heating sheet

Abstract

The invention provides a nanometer far infrared carbon-fiber heating sheet. The nanometer far infrared carbon-fiber heating sheet comprises a far infrared heating layer, flexible substrate layers andtwo pieces of conductive cloth, wherein the flexible substrate layers are attached to two sides of the far infrared heating layer; the far infrared heating layer comprises carbon fibers which are arranged in a netlike shape; two opposite ends of the carbon fibers which are arranged in the netlike shape are connected with the conductive cloth in a covering way; and the two pieces of conductive cloth are connected with a power connector through cathode-anode leads. The far infrared heating layer comprises the carbon fibers which are arranged in the netlike shape, and the two opposite ends of thecarbon fibers which are arranged in the netlike shape are connected with the conductive cloth in the covering way, so that potential safety hazards such as loosening of a conductive heating body andfire hazard caused by static electricity are avoided.

Description

technical field [0001] The invention belongs to the technical field of nano far-infrared carbon fiber heating, in particular to a nano far-infrared carbon fiber heating sheet. Background technique [0002] Carbon fiber (Carbonfiber) is an inorganic fiber composed of carbon elements. The carbon content of the fiber is greater than 90%. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. Produces far-infrared thermal radiation that is extremely beneficial to human health (about 765.9W / M, equivalent to a spectrum physiotherapy instrument), and its electrothermal conversion rate is over 95%, which is 30% more energy-saving than nickel-chromium, tungsten-molybdenum and other materials used as heating elements ; Moreover, it is very strong directly absorbed by the human body, clothing, etc., and the heat loss is small during the heat transfer process. Carbon fiber also has many characteristics ...

Problems solved by technology

[0004] The Chinese patent with the notification number CN103079297A discloses a carbon fiber heating sheet and its preparation method. It is to lay carbon fiber filaments on the lower insulation coating layer to form a carbon fiber layer with a network structure, and press electrode strips at both ends of the carbon fiber layer and lay Cover the insulating layer, after the bonding treatment, weld the electrode leads at the corresponding two ends of the electrode strip, however, in this process, it is necessary to coat the upper and lower insulating coating layers with hot melt adhesive, and the brass mesh is double-sided after annealing Hot-melt adhesive is applied, bonded and cut into strips, and the carbon fiber layer needs to be formed with a mold. The actual operation of this preparation method is relatively complicated, requiring more materials and equipment, which limits the production time and high production cost.

[0005] Our last invention patent: 201410844887.2 discloses a method for making a carbon fiber heating sheet, but it uses high-insulation cotton thread or polyester thread, and the edge of the conductive heating element is not connected by a conductive device, and there is no waterproof function, but it is conductive The heating element is loose and static electricity will cause fire safety hazards, and the human body's sweat soaks into the conductive heating element, avoiding the safety hazard of being corroded by sweat; improving the service life and safety of the heating sheet
