Abstract
The utility model relates to a conducting heating plate with alternating current-direct current, comprising a coating layer, a non-metal electrical conduction heating element and an insulating layer, wherein, the coating layer is textile sheets with cotton, hemp, wool or synthetic fiber materials; the electrical conduction heating element is a non-metal wire which is twisted by carbon fibers and polyester fibers or is composed of the carbon fibers; the insulating layer is the compound of polyester gum and polyolefine with the advantages of high-temperature and high-pressure resistance, and good fire retardance, malaxate character, good tensile resistance and flexing resistance. The utility model with simple structure can be as a heating and thermal insulating product for daily use.
Description
The utility model is all spendable conductive exothermal sheet of a kind of alternating current-direct current, especially relates to by yarn fabrics such as cotton, hair, fiber crops or synthetic fibers as coating layer, nonmetal conductive exothermal element and insulating barrier is arranged and the conductive exothermal sheet that constitutes in its coating layer.
Present more employed conductive exothermal article, electric blanket (cotton-padded mattress) etc. for example, because its conductive exothermal element is to adopt the metal wire with certain rigidity, and, very thick insulating material need be set in the outside of its line for making its insulation, so just make troubles to use, can not bend, more can not soften and rub with the hands and washing, and special heavy, bring some limitation to use.
The purpose of this utility model is exactly the deficiency that overcomes prior art, and a kind of gentle stranding with the hands and washing of not being afraid of is provided, heat efficiency height, the conductive exothermal sheet that insulation effect is good, and can use alterating and direct current.
The purpose of this utility model realizes by following content, conduction backing of the present utility model comprises coating layer and nonmetal conductive exothermal element and insulating barrier, wherein said coating layer is the textile sheet material, it can be by cotton, hair, fiber crops or synthetic fibers constitute, thickness is 0.1mm-1.5mm, in coating layer, be arranged with nonmetal conductive exothermal element, the conductive exothermal element-external has that a kind of to have cohesive force strong and insulating properties arranged, fire resistance, mar proof, pliability is good, the polyester of no side effects and TPO compound insulating barrier, it forms by brushing, described non-metallic heating element is to have the line that the carbon fiber of the twist becomes with the polyster fibre ply twist with twist, perhaps only constituted by carbon fiber with twist, wherein the fineness degree of carbon fiber is that the carbon fiber of 1-6K(1K unit has 1000 carbon fibers), when non-metallic heating element is carbon fiber and polyster fibre, wherein the fineness degree of polyster fibre is identical with the carbon fiber fineness degree, and polyster fibre becomes the sth. made by twisting of line to twisting with the fingers to identical with its fiber with the carbon fiber ply twist.Nonmetal conductive exothermal element in coating layer can be arranged as required, as parallel connection, or only by a bend alignment, when the input of power connection conductive exothermal element, just can make it produce heat, this product adopts 220V or the following safe voltage of 36V all can, combined-voltage all can use, and the resistance value of its conductive exothermal element is 30-600 Ω/rice, and its thickness of insulating layer is 0.01-3mm.
The utility model is simple in structure, the user can select all size to differ as required, the kind that specification does not wait, with it is pyrotoxin, make required separately finished product, as the conductive exothermal sheet is made in some daily necessitiess of sleeping bag, ready-made clothes, footwear, cap, gloves or the like, play warming and heat insulation, because its cost is low, make simple, applied range is not afraid of violent gentle stranding, and bendable can be rolled over, life-span is long, consumed power is little, needn't worry the fracture of conductive exothermal element or puncture insulating barrier to cause the accident, and is the insulation heating product of a new generation.
Further describe structure of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of another embodiment of the present utility model;
Fig. 3 is the schematic diagram of a kind of conductive exothermal element of the present utility model and insulating barrier;
1 is coating layer among the figure, and 2 is nonmetal conductive exothermal element, and 3 is insulating barrier.Conductive exothermal element 2 is arranged between two coating layers 1, conductive exothermal element 2 outsides comprise one high temperature resistant, high voltage bearing insulating barrier 3, this conductive exothermal element 2 can be a long lead in coating layer 1 and arrange with curve form as required, also can be to arrange (as shown) with the form of parallel connection, conductive exothermal element 2 can be the nonmetal electric heating lead that is made of carbon fiber and polyster fibre, but also only constituted by carbon fiber, conductive exothermal element 2 is fixed on the coating layer 1 by binding agent, also can make on coating layer 1 by line, coating layer 1 can be by cotton or fiber crops or the yarn fabrics that textile material constituted such as hair or synthetic fibers.Press the input A of admittance electricity heating sheet when power supply after, the conductive exothermal element is then heatable.According to user's needs, select the resistance value of its conductive exothermal element, and make the specification size of conductive exothermal sheet according to the various situations of use.
