Problems solved by technology

[0003] Hydrochloric acid and alkaline components are likely to remain inside the above-mentioned heating body, which will reduce the service life of the surface of the heating body
In particular, circuit lines formed of aluminum foil are often partially damaged during the corrosion process, and flames are likely to be induced when the surface of the heating body is heated.
In the manufacturing process of the heating body, hydrochloric acid and other corrosive agents are used to corrode ink and aluminum foil. The corroded aluminum, hydrochloric acid, sodium hydroxide, etc. will produce substances harmful to the environment and cause environmental pollution.
If you want to replace the alkaline aqueous solution such as sodium hydroxide aqueous solution for corrosion ink and etchant, it will increase the manufacturing cost

Embodiment 1

[0021] Example 1, figure 1 It is the engineering diagram of the manufacturing method of the PTC type electric heating mirror. An electric heating mirror (100) is formed by covering the metal surface (102) on the back of the glass (101).

[0022] Depend on figure 1 , figure 2 As shown, the glass plate (101) is prepared according to the specifications and sizes required by the electric heating mirror, and the covering surface (102) is formed with metals such as nickel, aluminum, chromium, etc. on the back of the glass plate (101), and epoxy resin is generally used on it. A series of insulating inks etc. form an insulating layer (110) (reference figure 1 A), after the insulating layer (110) is formed, use conductive inks such as carbon liquid, aluminum, copper, silver, gold ink, after the circuit line (120) of specific shape is directly printed on the insulating layer (110) and dried ( refer to figure 1 B), at this time, the above-mentioned circuit line (120) can be formed ...

Embodiment 2

[0025] Example 2, image 3 It is an engineering drawing of the manufacturing method of the PTC type electric heating mirror. This method is applicable to the electrically heated mirror (200) formed on the glass (201) front surface with a metal covering surface (202).

[0026] Depend on image 3 , Figure 4 As shown, according to the required regulations, prepare a glass plate (201) with a specific size and shape, form a covering surface (202) with metal on the front of the glass (201), and use conductive inks such as carbon liquid, aluminum, copper, silver, and gold ink On the back side (201) of glass (201), directly print and dry by the circuit line (210) of specific shape (refer to image 3 A), at this moment glass plate (201) and Figure 5 The effect of the insulating layer (310) shown is the same, and the above-mentioned circuit line (210) can be formed in a variety of ways, forming the circuit line (210) on the back of the glass (201) and the surface ( 201a), after t...

Embodiment 3

[0029] Example 3, Figure 5 It is the engineering diagram of the manufacturing method of the NON-PTC type electric heating mirror. This method is suitable for the electric heating mirror (300) formed by covering the metal surface (302) on the back of the glass (301).

[0030] Depend on Figure 5 , Image 6 As shown, according to the required regulations, prepare a glass plate (301) according to a specific size and shape, and use nickel, aluminum, chromium and other metals to form a covering surface (302) on the back of the glass plate, and generally use epoxy resin series insulation on it. Ink etc. form the insulating layer (310) (reference Figure 5 A). After the insulating layer (310) is formed, use conductive inks such as carbon liquid, aluminum, copper, silver, and gold ink to directly print and dry according to the circuit line (320) of a specific shape on the insulating layer (310) (refer to Figure 5 B), at this time, the circuit line (320) can be formed in a varie...

Description

Technical field [0001] The invention relates to a mirror that needs to be heated to melt and evaporate frost and moisture formed on the mirror surface, in particular to an electrically heated mirror and a manufacturing method thereof. Applicable such as car rearview mirror or bathroom mirror. Background technique [0002] Generally applicable to various electric heating mirrors such as car rearview mirrors or bathroom mirrors. The heating element is manufactured separately. The mirror is heated by the heating element attached to its back, and the frost and moisture formed on the mirror surface melt and evaporate. . The heating body installed on the surface of various electric heating mirrors includes PTC resistors such as carbon liquid or silver ink, which are connected in parallel to form current input terminals, and NON, which does not include the above-mentioned PTC resistors and is formed as current input terminals in series. - PTC type. In Korean Patent Registration ...
