Problems solved by technology

However, the problem with heating glass according to the above method is that it is difficult to drive it at low voltages below 40V due to the high surface resistance
As other methods, in the photolithography method, due to the complicated preparation process and serious waste of materials, products cannot be prepared at low cost, so this method cannot be used to prepare heated glass

Embodiment 1

[0078] As a silver paste, a silver paste for low-temperature sintering produced by Fujikura Co., Ltd. was used. As the intaglio plate, glass having a pattern orthogonally formed in a grid form at a pitch of 300 micrometers, a width of 20 micrometers, and a depth of 7.5 micrometers was used.

[0079] After the polyester-based primer was stick coated onto a PET film (thickness 125 microns), it was dried for 2 minutes for the primer treatment. in use as figure 1 After forming the silver pattern in the grid form by the manner and lithography machine shown, silver lines were formed by sintering at 150° C. for 30 minutes. In this case, silver lines were formed with an interval of 300 micrometers, a width of 25 micrometers, a height of 1.5 micrometers and an aperture ratio of 84%. After cutting the substrate into a size of 275mm×270mm, it was placed between EVA with a thickness of 400 micrometers, and by putting the above-mentioned complex (complex) between glasses with a thickness...

Abstract

The present invention relates to a method for manufacturing a heater that includes: a step of determining a form of a pattern in which the line width of the pattern is 100 micrometers or lower and the aperture ratio of the pattern is 70% or higher and 99% or lower; a step of printing a paste containing a conductive heating material onto at least one surface of a resin film in accordance with the pattern determined in the previous step; a step of firing the printed paste containing the conductive heating material to form a conductive heating pattern; a step of forming bus bars at both ends of the conductive heating pattern; a step of bonding a transparent base to at least one surface of the resin film having the conductive heating pattern; and a step of preparing a power source connected to the bus bars. The invention also relates to a heater manufactured by said method.

Description

technical field [0001] The invention relates to a heating element and a method for preparing the heating element. More particularly, the present invention relates to an imperceptible heating element having excellent heating performance at low voltage and a method of manufacturing the heating element. Background technique [0002] In winter or rainy days, due to the temperature difference between the exterior and interior of the vehicle, frost will form on the glass surface of the vehicle. Furthermore, in the case of indoor ski resorts, freezing occurs due to the temperature difference between the interior of the slope and its exterior. In order to solve the above problems, heated glass has been developed. Heating glass adopts the idea that after attaching the heating wire sheet to the glass surface or directly forming a heating wire on the glass surface, an electric current is applied to the two ends of the heating wire to generate heat from the heating wire, thereby incre...
