Abstract
The present invention relates to an infrared radiation electrothermal film and a manufacturing method thereof. The infrared radiation electrothermal film comprises insulating films and a conducting circuit, wherein the conducting circuit which is made of a metallic film is arranged between the insulating films. The manufacturing method of the infrared radiation electrothermal film comprises the following steps: the metallic film is compounded on the insulating films; the conducting circuit is printed by an anticorrosive material; the metallic film on which the conducting circuit is printed is soaked in corrosive solution to be corroded; the conducting circuit which is cleaned by clean water is baked and dried; the insulating films are compounded with the conducting circuit; at last, leading wires are led out. The present invention has the advantages of simple technology and low cost, and is suitable for wholesale manufacture. A production of the present invention has uniform resistance, firm electrodes and a long service life. The present invention can be widely used in the fields of electrothermal warming, heating, etc.
Description
The present invention relates to a kind of electric heating material and production method thereof, especially a kind of red infrared radiation electrothermal film and production method thereof.
At present, be with the immediate prior art of the present invention that the patent No. is 89216930, name is called the utility model patent technology of " low-voltage direct generate heat warming body ", this patented technology is to clip the metallic film heating layer that one deck is formed by vacuum evaporation or spraying between two insulating barriers, because the metallic film heating layer is a full wafer, its cross-sectional area is big, resistance value is very little, if make the electrothermal product, very big electric current must be arranged, just can reach required power, current density is big, so just very easily produces ELECTROMIGRATION PHENOMENON, unstable product quality, reliability is low.
One of purpose of the present invention provides that a kind of technology is simple, cost is low, can be fit to produce in enormous quantities, stay-in-grade red infrared radiation electrothermal film.
Two of purpose of the present invention provides a kind of production method of red infrared radiation electrothermal film.
Technical solution of the present invention is:
A kind of red infrared radiation electrothermal film, comprise insulation film 2,4 and place metallic film heater between the insulation film 2,4, described metallic film heater is by being covered with the conducting channel 3 that the metallic film lines that contain the infrared radiant material anticorrosive coat constitute, and conducting channel 3 is joined with power line 6.
Described conducting channel 3 and tinplate 5 riveted joint backs and power line 6 welding.
A kind of production method of red infrared radiation electrothermal film comprises the steps:
A. metallic film 1 is compounded on the insulation film 2, on metallic film 1, uses and contain the corrosion-resistant material printing of infrared radiant material and the corresponding figure of figure of conducting channel 3;
The metallic film 1 that b. will be printed with the corrosion-resistant material figure is immersed in the etchant solution and corrodes;
C. wash etchant solution with clear water, baking, drying;
E. draw lead.
Described insulation film 2,4 is the PET polyester film of 20-50 μ m, and described metallic film is aluminium or copper, and its thickness is 9-20 μ m.
Described corrosion-resistant material is an alkali resistance printing ink, and described etchant solution is an alkaline solution.
Described corrosion-resistant material is an acid-resisting printing ink, and described etchant solution is an acid solution.
Described baking, drying are with infrared ray baking, drying.
The present invention compares with prior art, and its technology is simple, cost is low, can be fit to production in enormous quantities.The product of being produced can not produce the phenomenon of burning owing to local overheating.Special technology can make electrode and electric conductor riveted joint, thus difficult drop-off, constant product quality, long service life.As long as regulate the sectional area of the metallic film lines that constitute conducting channel, can adjust its temperature, to be fit to the usefulness of electrothermal.
Fig. 1 is the schematic diagram of embodiment of the invention a step.
Fig. 2 is the schematic diagram of the embodiment of the invention.
The present invention will be further described below in conjunction with drawings and Examples.As Fig. 1, shown in Figure 2: as at first metallic film 1 to be compounded on the insulation film 2, metallic film 1 can be aluminium or the copper behind the 9-20 μ m, and insulation film 2 can be the PET polyester film of 20-50 μ m, after compound, available alkali resistant or antiacid printing ink are printed the corresponding figure of figure with conducting channel 3 on metallic film 1, in printed ink, add infrared radiant material, as FeO, CuO etc., after printing is finished, place etchant solution to soak the metallic film 1 and the insulation film 2 that are combined with each other, if the corrosion-resistant material figure is to be printed by alkali resistance printing ink to form, then be placed in 5% the NaOH solution; If the corrosion-resistant material figure is printed by acid-resisting printing ink and formed, then be placed on 5% Fecl
3In the solution, will erode, promptly form the conducting channel 3 that is compounded on the insulation film 2 except the metallic film being printed with the corrosion-resistant material figure 1; Afterwards, clean with clear water, wash reaction product and acid-base solution off, toast, drying, the most handy infrared ray toasts, drying.After baking, the drying, the PET polyester film 4 with 20-50 μ m is compounded on the conducting channel 3 again, welds with conducting channel 3 riveted joints and with power line 6 with tinplate 5 at last, has promptly finished the production of red infrared radiation electrothermal film.
