New description: [Technical field of new type] The present invention relates to a self-controlled temperature electric heating cloth containing bamboo charcoal powder and crystalline hot squeezing resin 'When a certain set temperature is reached, the heating is automatically stopped. The electric heating cloth with temperature-controlled components is especially suitable for providing warmth of clothing and protective gears. When equipped with a rechargeable battery, it has the functions of warmth and health care in action, and is an ideal electric heating element. [Prior Art] • (4) Knowing the secrets of clothes and secrets, all use a certain thickness to make the air stop secret _, using air, poor heat conduction, to achieve the effect of heat insulation, so that the body temperature can be maintained or reduced, to achieve the purpose of keeping warm; In the direction of its efforts, it is not necessary to make the fiber body or ultra-fine or towel feather-like to enhance the heat insulation effect. Recently, far-infrared warm cotton has been added to the non-woven fabric to add pottery powder with the same radiation wavelength as the human body, or to have the effect of pulling the outer line, and to make the heat penetrate into the bottom layer of the skin, thereby promoting the warming of the blood circulation. The effect of health care, or the combination of the phase transfer material and the fiber, pastes the endothermic and exothermic side to achieve the purpose of heat preservation, but the elevated temperature is only Η ^ C 'the effect is not obvious. $ Yes, with nickel-chromium or white iron or its alloy electric heating wire, arranged or twisted back to make a thermal resistor body, but due to low metal, the battery is "low power (four) in 12V town, its electricity _ very small , the monthly b to meet the demand for warmth and heat; at the bend and the joint, it is easy to cause the main reason for the open circuit. Secondly, on the polymer film PET, the silver electrode is printed, and the carbon glue heating element is printed, and the upper and lower layers are insulated into a heating element, and the structure thereof is in the form of a sheet. When the bending is performed, internal cracks are easily generated, and the electric resistance is increased and the loss is lost. The fever Wei, more carbonized cloth, is paved as a parallel electrode, covered with a soft polymer film and hot-pressure fusion, the structure is soft, but the bending is easy to form a line break or power loss. 5 M325698 is said to make up the fine part of the joint axis, the dirty matter of the object, the constant accumulation of heat, resulting in low temperature burns, so you need to choose temperature control means, bribe road, its towel _, with - petals _, wall Great, high and low temperature is obvious, if the electronic circuit, the sensor and a set of temperature control components, in addition to increasing the cost, the convenience and comfort of carrying is also unfavorable. This creation is improved in solving the above-mentioned actions to keep warm _ questions missing, _ taking into account the stability of electrical characteristics, warmth, comfort, power saving, flexing resistance and other characteristics. [New content] This hair dragon is improved according to the shortcomings of the company. It is very suitable for the self-controlled temperature heating cloth designed for the purpose of wearing protective gear, etc. _ in the resistance to the flesh and the heat of the day. Bamboo charcoal powder, which has at least 80 or more of bamboo material, carbonized, carbonized degree, at least 80% or more, is processed into fine powder by grinding, and its particle size is 〇·〇5~5〇min, which has higher conductivity. , or chemically grafted surface treatment to reduce the agglomeration of the powder due to cohesion, to ensure uniform dispersion with the crystalline thermoplastic resin, and the resistance value can be stably controlled in the required range, and the crystalline thermoplasticity The weight ratio of the resin, the bamboo charcoal powder accounts for 3〇~6〇%, and the ratio is 45%. The particle size can be mixed by single or two different particle sizes, and the plane impedance is preferably 0.1 to 100 Ω/□. . a crystalline thermoplastic resin having a fixed melting point and a neat lattice arrangement with a degree of crystallization of at least 30%, such as a polyolefin resin, including polyethylene, polypropylene, tetrafluoroethylene, ethylene vinyl acetate, and Copolymer, gasified ethylene, polyamine, polycarbonate, polyacetal, polyethylene polyacrylate or flexible such as ethylene-propylene rubber, gas sulfonated ethylene rubber, fluoro rubber, silicone rubber, etc. , can be single or more than one, mixed together. When uniformly mixed with a compatible solvent to form a conductive ink, due to the regular arrangement of the crystalline resin, the solvent resistance of 6 M325698 is better, and it is difficult to form an ink. Especially in the case of a crystallization degree of 5% or more, the solvent is more difficult to penetrate into the solvent. Between the crystal lattices, it is necessary to add heat treatment or in a closed or vacuum; firstly, the crystal is heated and expanded into an amorphous state, and then disintegrated into an ink, and the temperature applied is at least higher than the melting point of the crystalline resin. Above, the solvent is as follows: toluene, xylene, acetone, triethylene acetophenone, methyl ethyl ketone, methyl isobutyl hydrazine, four wind crunch, different, its boiling point can be higher than the tree position, can be transferred - Or a mixture of three or more kinds may be used, and the weight ratio to the crystalline resin is preferably about 2 to 3 times. The coating process mainly makes the conductive ink uniformly permeate on the base cloth to provide a circuit for current conduction and heat generation. The stable impedance is a necessary condition, and can be printed, transferred, immersed, sprayed, rolled, - times or more, to achieve the required thickness, wherein the film thickness is most easily controlled by printing, the processability is stable, and the density of the mesh is simply changed to achieve stable impedance. In practice, 4 (M2 mesh is suitable, or continuous production) The job is to be rolled, firstly impregnated, and then controlled by two rollers to control the thickness and the number of coatings. It is easy to control the impedance between 〇·1~100Ω/□. Pre-wired wire cloth bonding, electrode material# _ fine lining or copper nickel-plated thin wire, its wire diameter is G· 05~G· 1 mm, can be single-strand or pre-shaped miscellaneous wire, and long-fiber false 捻, so that it can be entangled with the fiber, and then Weaving into the base fabric; providing power supply, and the distance between the electrode and the electrode is determined by the required surface temperature and voltage and conductive ink. The actual surface temperature of the 12V is 45. 〇, the impedance is 1 〇 ω The electrode distance is 2 ~10 cm, while the base fabric material, you can choose the thief Fiber, or inorganic glass fiber can be used, the shape can be plain or non-woven, and it is not suitable for stretching. Among them, Tedron is preferred because of its reasonable price, small extension length, and surface and crystalline resin. Repellent phenomenon, easy to adsorb and infiltrate and achieve reinforcement, and the change in impedance for a long time is also small. The purpose of heating the solvent is to restore the crystallinity of the crystalline resin to achieve its own function of controlling temperature. Because the positive temperature coefficient is the impedance increases with the temperature, the impedance increases, and its mechanism of action, 7 M325698 is the crystallinity _, and the bamboo charcoal powder forms a scale electric material through the power supply. At this time, the bamboo charcoal particles are connected in a bead shape into a loop. The silk ear is hot, the scale crystal tree is heated, and (10) the crystal is converted into an amorphous phase, and the volume is swollen, so that the particles of the bamboo charcoal powder and the grain tilting gap are pushed away, so that the electric resistance decreases and the current decreases. The temperature is lowered, and the effect is repeated, and the temperature is reached, and the degree of crystallinity is increased, and the volume is more secreted. 'Temperature_ makes the job difficult, so the fine crystallinity is maintained when the solvent is removed. On the top, it can be dried by hot air circulation oven or continuous infrared ray. The temperature is at least higher than the impurity of 2GC above the solvent. It is suitable for (10)~ job. When the solvent is volatilized, the crystallinity is greatly affected by the cooling rate even if the ratio of the same resin or bamboo charcoal powder When the cooling rate is too fast, the crystallinity is small, so that the control itself, b is not the month ββρ positive temperature system is small, so the control of the cooling curve is extremely important, generally 10 2 GC per minute, such as continuous producers, money towel to do cooling treatment And (4) hourly, in order to make the crystals completely tempered and stable. > The purpose of the upper and lower shunting and laminating treatment is to make the conductive ink on the fiber get the sigh of fixation and achieve the purpose of insulation to ensure the stability of the impedance. Sex, its material selection is used by general users such as ΡΕΤ· EVA or pp, its thickness is 〇•~·5^1, the inner side is coated with adhesive glue, and it is cold pressed or hot pressed on the electric heating cloth, showing monthly/mouth pressure σ In the center, it becomes a positive impedance temperature coefficient electric heating cloth. : Members' progress is understood as follows: (Fig. 1) The plan of the creation and (Fig. 2) Sectional view of the creation · 8 M325698 [Embodiment] Polyvinyl acetate (20) xylene + toluene (1: 1) 50 Bamboo charcoal powder (50 mm) 12 Add polyvinyl acetate to xylene and toluene and maintain at 85 in a closed bucket. 〇 stir for 30 minutes, in a translucent paste; add bamboo charcoal powder dried at 105 ° C for 30 minutes, also maintain 85 ° ° C, and vacuum, followed by stirring for 1 hour, a black conductive ink, with 120 mesh Version, with a scraper φ brush on a 10 〇mmxlOOmm Tedron cloth (where the distance between the copper wire electrode and the electrode is 2 〇, pre-woven into the cloth), placed in 13 (TC hot air circulation oven 30 minutes The solvent is completely removed, and is cooled down to a temperature of 1 ° C per minute for 24 hours. 'The electrodes are connected in parallel; the impedance is 12 Ω with a three-meter meter. Detecting electrical characteristics: (1) Open state Positive impedance temperature characteristics: (Figure 3) At a temperature of 25 C, the 12VDC power supply is introduced '2 minutes to reach the surface temperature of 45 ° C, and then the constant temperature. (2) In the closed state, the positive impedance temperature characteristics and time, The relationship between the three currents: (Figure 4) At room temperature 25 ° C, the electric heat is placed in the center of two 30 mm polystyrene hair plates, under the adiabatic, the 12 VDC power supply is measured to measure the positive impedance temperature characteristics. ) The initial current is 1A, and reaches 1.5°C (saturation temperature) at 1 minute. Decrease to 〇·3A to stabilize current. (2) After 30 minutes, the temperature is maintained at 47 °C; the current is reduced to 〇·28 to exhibit a secondary stable current. (3) Flexural resistance test: (Figure 5) with radius 30 Let the cylinder 'on the electric heating cloth, reciprocally fit and bend 3 times, and measure the resistance value 9
