Electrically heated automobile windshield glass

Abstract

The invention relates to the technology of automobile glass, and discloses an automobile electric heating glass window and a manufacturing method. Firstly, trapezoid cutting, edge polishing and washing are carried out on an FTO conductive glass substrate, and the FTO conductive glass substrate is dried to be used later; secondly, the hot bending and the tempering process are carried out on the processed FTO conductive glass substrate through a die, and after bent glass with the needed strength and curvature is obtained, the edge and two opposite frames of the glass substrate are printed or pasted with conductive metal strips to form the positive electrode and the negative electrode; lastly, the positive electrode metal strip and the negative electrode strip are connected with a power source through an electrical connecting device, and then the automobile electric heating glass window is manufactured. The face heating method is adopted, the automobile glass can be heated more evenly, and bursting caused by uneven heating of the glass is effectively prevented; under the high temperature, the sheet resistance change is very small, the heating performance of the automobile electric heating glass window is changed little even when the automobile electric heating glass window is processed through heating bending and tempering, the appearance of an automobile can be beautified, and the back vision effect of a driver can be improved.

Description

technical field [0001] The invention relates to the automobile windshield technology, in particular to an electric heating automobile windshield. Background technique [0002] Automobile glass is one of the important safety components of automobiles. It has the functions of protecting occupants, waterproofing, dustproofing, heat resistance and sound insulation. Today, the area of ​​automotive glass accounts for about 1 / 3 of the surface area of ​​a car. According to the application site, automotive glass mainly includes front windshield glass, rear windshield glass, door glass, sunroof glass and front / rear corner window glass, etc. As early as 40 years ago, the windshield of automobiles had adopted a single-piece curved windshield, and gradually abandoned the flat windshield. Today's car windshields are generally made into a large curved surface with a certain curvature on the top, bottom, left, and right. With the development of the automobile industry, the application of...
