Problems solved by technology

[0003] In the manufacturing process of the above-mentioned heating film, in order to corrode the ink and aluminum foil, etchant such as hydrochloric acid needs to be used. If the etchant is not used, but an alkaline aqueous solution such as sodium hydroxide aqueous solution is used instead, there is a problem in manufacturing cost, especially in the manufacturing process. Aluminum, hydrochloric acid, sodium hydroxide, etc. will produce harmful substances and pollute the environment
Moreover, the residual hydrochloric acid and alkaline components inside the heating film will also reduce the service life of the heating film
In particular, circuit lines formed of aluminum foil are often partially damaged during the corrosion process, and there is also the disadvantage of inducing flames during the heating of the heating film surface.

Embodiment 1

[0017] Embodiment 1: The manufacturing method of PTC type heating film is described in detail. Such as figure 1 As shown, at first determine the size of insulating layers (10) such as PET layers according to the required specifications, and form rolls after cutting. refer to figure 1 The PTC type heating film manufacturing method engineering drawing shown in figure 1 A, (reference figure 1 A).

[0018] Water-soluble Metallize Resist ink (resist ink treated with metal) is overprinted on the specified electrode layer on the surface of the insulating layer, and dried. (refer to figure 1 B). The water-soluble Metallize Resist ink (resistance ink processed with metal) used in the production process of the present invention is the kp-1000 product manufactured by Korea KTS Co., Ltd.

[0019] After the circuit line (20) is printed on the insulating layer (10), the part (11) of the non-printed circuit line (20) on the surface of the insulating layer is selected from copper, silv...

Embodiment 2

[0023] Embodiment 2: The manufacturing method of the PTC type heating film is described in detail. First, if figure 1 After the insulating layer (10) shown in A is prepared, as figure 1 As shown in B, on the electrode layer specified on the surface of the insulating layer (10), cover the surface of the insulating layer (10) with a protective mold (shown at the end of the figure) to form a specified circuit line (20), and use a protective mold instead of using a water-soluble Metallize Resist ink (resistive ink processed with metal) forms circuit lines (20) on the insulating layer (10).

[0024] After the circuit line (20) on the insulating layer (10) is formed, on the part (11) of the surface of the insulating layer (10) that does not cover the protective mold, use copper, silver, and gold to choose one of gold plating or vacuum coating to form a specified electrode layer (30) (reference figure 1 C), the circuit line (20) can be designed and manufactured according to needs,...

Embodiment 3

[0029] Embodiment 3: The manufacturing method of the NON-PTC type heating film is described in detail. image 3 It is an engineering drawing of the NON-PTC type heating film manufacturing method. First determine the size and shape of insulating layers (10a) such as PET layers according to the required specifications and cut them into rolls. (refer to image 3 A)

[0030] After the above insulating layer (10a) is prepared, the prescribed circuit lines (20a) are covered and printed on the insulating layer with water-soluble Metallize Resist ink (resist ink treated with metal), and dried. (refer to image 3 B) The water-soluble Metallize Resist ink (resistive ink treated with metal) used is a KP-1000 product manufactured by Korea KTS Co., Ltd.

[0031] After the circuit line (20a) is printed on the insulating layer (10a), choose one of copper, silver, and gold, and on the uncovered part (11a) above the insulating layer (10a), gold plating or vacuum plating forms a specified Th...

Abstract

The invention relates to a preparation method for heat film and opposite heater. Wherein, with the water-soluble Metallize Resist ink on insulation layer or assistant mold, gilding or vacuum coating for electrode line, using PTC ink to print the part not-formed electrode layer into special shape; or after coating film on not-formed electrode line upper, connecting the current input terminal parallel or in series. This invention is easy and low cost, saves erosion process, does not induce flare, and prolongs service time.

Description

Technical field [0001] The invention relates to a method for manufacturing a heating film and a related heating element, which is suitable for related heating elements such as automobile rearview mirrors, bathroom mirrors or heating heating films. Background technique [0002] The past heating film generally includes carbon liquid and silver ink PTC resistors, PTC type with parallel terminal structure and NON-PTC type with PTC resistor series terminal structure. In the PET layer of the heating film, the aluminum film with the insulator is coated with a layer of corrosive ink on the aluminum film with an insulator. In order to protect the printed conductive circuit, the part that is not coated with the corrosive ink is removed by a chemical reaction with an etchant, and then on it Carbon liquid is printed on the surface to form a circuit layer, and an aluminum heating film that connects parallel lines through connecting terminals. In addition, in the process of manufacturing...
