Circular electric heating glass and preparation method and application thereof

Abstract

The invention mainly provides circular electric heating glass as well as a preparation method and application thereof. The glass comprises a first glass substrate which is circular flat glass; the first glass substrate is non-conductive; a conductive film layer is arranged on the first glass substrate; the peripheral contour of the conductive film layer is circular and coincides with the contour of the first glass substrate; the conductive film layer comprises a conductive region formed by a conductive material and a strip-shaped insulating region without the conductive material; the strip-shaped insulating region separates the conductive region to form a resistor consisting of a plurality of transparent conductive bands which are sequentially connected in series; the transparent conductive bands at the two ends of the resistor comprise free ends; the free ends are located at the edge of the conductive film layer; the average width of the strip-shaped insulating region is less than orequal to 1.5 mm; the width difference of the transparent conductive bands is less than or equal to 5%; and two electrodes are respectively connected with the two free ends. The invention solves the technical problems, and the electric heating glass is not limited by the shape and can be uniformly heated; and the temperature is integrally uniform, the service life is prolonged, and the applicationfield is widened.

Description

technical field [0001] The invention belongs to the technical field of electric heating glass, and in particular relates to a round electric heating glass and its preparation method and application. Background technique [0002] Aviation transparent parts are easily affected by frost. In order to enable aviation transparent parts to have the function of anti-icing and defogging, the transparent parts are made of electrically heated glass. Electric heating of glass is achieved by setting an electric heating film layer on the glass. Due to its good conductivity and high transmittance, the ITO film can be used as the first choice for the electric heating film of transparent parts. At present, ITO film is used as the electric heating film of transparent glass in aviation and other fields. Set the ITO film on the glass, set the bus bars at both ends of the film and connect the wires, then it can be used as an electric heating film. [0003] Since the surface resistance of the I...

AI Technical Summary

Problems solved by technology

But if the shape of the transparent part is irregular, for example, when the circular glass, then the overall temperature of the electric heating glass is not uniform, and the heating uniformity of the film layer is relatively poor, which will directly affect the electric heating glass. service life
