Description

Transparent heating glass manufacturing method {Method for Transparent Heating Glass}

The present invention enables to secure visibility by quickly and effectively removing moisture or sexuality generated during operation of automobiles, ships, and airplanes, and transparent heat generation for effectively preventing condensation and energy emission generated in glass of buildings in winter. It relates to a glass manufacturing method.

At present, air conditioners or heaters are used on the front glass to remove the frost, moisture, and winter ice that occur on the glass while driving the car. As this occurs, the heating wire is removed by raising the temperature of the coated glass. However, the method of removing by using an air conditioner or a heater has energy consumption and inconvenience of operation while driving, and since the coated heating wire is opaque, it cannot be applied to the front glass of the car, but only to the rear glass. Because it interferes with the problem, there are problems that can cause a safety accident such as a traffic accident.

Another recent method for manufacturing a heat generating glass is to form a heat generating layer by coating ITO (Indium Tin Oxide) on the glass as a thin film or by sputtering a conductive material such as silver (Ag) on the glass. Although there is a method of connecting and removing the electrode, in the case of ITO, the reserves of raw materials are limited, so the price is high and the use is limited at low voltage (below 40V) due to the high resistance.

In order to solve the above problems of the prior art, the present invention is to provide a transparent heat generating glass having a high transmittance and low resistance and a transparent heat generating glass having excellent transmittance and low resistance while constructing the glass using the same It is aimed.

As a solution to the above, the exemplary embodiment of the present invention comprises the steps of forming a heating pattern by imprinting a fine pattern with a transparent substrate and a mold having a fine pattern (2-6 μm) formed on one surface of the transparent substrate, and a conductive material on the heating pattern. Forming a heating line by filling the step, connecting the electrode busbar to the heating wire to form a transparent heat generating substrate, transparent heat generating glass comprising the step of forming a glass with a transparent heating substrate connected to the electrode busbar Provide a method.

Another embodiment of the present invention is a method of manufacturing a transparent heat generating glass using a glass substrate, the step of applying a photoresist on the glass substrate, the fine pattern on the glass substrate coated with the photoresist (line width 20㎛ Exposing with a photomask, etching the exposed pattern, applying a conductive material to the etched heating pattern, forming an electrode busbar, and then forming a heating line. Provide a method.

The present invention provides the above-described configuration, by constructing the glass using a heating wire excellent in light transmittance and electrical conductivity, can be applied to the glass of the front or rear of the vehicle to remove frost, steaming, moisture, etc. quickly and effectively Of course, the existing coated heating wire can eliminate the discomfort that obstructs the field of vision can prevent safety accidents. In addition, it is installed on the glass of the building to prevent condensation in winter and to prevent the heat emitted to the outside, so it is effective in keeping warm and improving the building energy efficiency. Vehicles to which the present invention is applied can be applied to vans, large trucks, construction equipment, etc., as well as general passenger cars, and also applied to building glass windows or home glass windows, and the application range of apartment complexes and large business complexes is very wide. Another field of application is as a heater for microscopes, submerged lenses, outer glass of ships and airplanes, and can be attached to portable face-mounted devices such as goggles and helmets for use with portable power sources.

Hereinafter, the present invention will be described in detail.

In the method of manufacturing a transparent heat generating glass according to the present invention, the micro-patterns are imprinted [A] [B] on the transparent substrate 120 and the molds 100 and 130 having the fine patterns 111 formed on one surface of the transparent substrate 120. Forming a pattern 122, filling the heating pattern 122 with a conductive material 124 to form a heating line 126, forming an electrode busbar 128 on the heating line 126, It provides a transparent heat generating glass manufacturing method comprising the step of constituting the glass 140 to the transparent heat generating substrate 135 to which the bus bar 128 is connected.

In the step of configuring the heating line 126, first, the heating pattern 122 is determined. The heating pattern 122 may be various patterns in consideration of the diffraction state of light such as a mesh type, a strike type, and the like. In order to form the fine pattern 111 on one surface of the transparent substrate 120 after the pattern is determined, the roller mold 100 or the plate mold in which the fine pattern 111 corresponding to one surface of the transparent substrate 120 is embossed is embossed. Imprinted at 130 to form a fine and elaborate heating pattern 122. It is preferable to pattern the line width of the heating pattern 122 to be 2 to 6 μm.

The material of the transparent substrate 120 may be a plastic film or glass. Here, although the material of a board | substrate is not specifically limited, It is preferable that light transmittance is 80% or more. Specifically, films such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polycarbonate (PC), polyimide (PI) may be used.

As the conductive material 124 constituting the heating line 126, a paste-type metal having excellent thermal conductivity is used. Specifically, silver (Ag), copper (Cu), gold (Au), or the like may be used. In this case, the heating line 126 may be formed on the heating line 126 by plating with a material having good conductivity, for example, nickel (Ni).

In the step of forming the electrode busbars 128 on the heating line 126, the electrode busbars 128 may be simultaneously formed when the heating line 126 is formed, or the electrode busbars 128 may be formed using screen printing. In this case, the thickness of the electrode busbars 128 is preferably 20 to 50 μm because heat generation of the contact portion may occur when the contact resistance between the heating wire 126 and the busbars increases.

In the step of configuring the glass 140 with the transparent heat generating substrate 135 to which the bus bar 128 is connected, the glass 140 and the transparent heat generating substrate 135 having the heating line 126 and the electrode bus bar 128 are formed. The glass 140 may be bonded to or adhered to the glass 140 to produce a transparent heat generating glass, in which the temperature and pressure in the bonding and attaching process may be adjusted.

According to another embodiment, a method of manufacturing a transparent heat generating glass is a method of directly patterning a heating pattern on a glass substrate 200 as a substrate of a transparent substrate. First, a photoresist 210 is coated and a fine pattern photomask 220 After exposing 230 to 230) through an etching process 240 to fill the conductive material 250 and to form a bus bar 260 to produce a transparent heat generating glass having a heating line. At this time, the line width of the heating wire is patterned to be about 20 ㎛.

In the present embodiment, as described above, the conductive material constituting the heating wire is a paste-type metal having excellent thermal conductivity. Specifically, silver (Ag), copper (Cu), gold (Au), or the like may be used. have. In this case, the heating wire may be plated with a similarly conductive material, for example, nickel (Ni), on the heating wire. In addition, the electrode busbar can be configured at the same time when forming the heating line, it is also possible to form the electrode busbar using screen printing.
