Automobile glass having electric heating function and heating method thereof

Abstract

The invention relates to an automobile glass having electric heating function and a heating method thereof. Automobile rear windshield with silk printing by a silver paste adopts a traditional technology, the finest width of the silver paste is about 1 mm, the cost for integrally printing by using a silver paste material is high, a heating wire is rough, beauty is influenced, and a certain of obstruction is generated for a driver to observe the vehicle rear environment. The invention provides the automobile glass having electric heating function, which comprises a bonding layer (3), a metal mesh (4) and a connection terminal (6), the connection terminal is directly welded on a bus electrode of the metal mesh, the bus electrode, the metal mesh and the connection terminal form a metal mesh conducting layer, the bonding layer is positioned between an external glass substrate (1) and the metal mesh conducting layer, an interlayer polymer (7) is arranged between the metal mesh conducting layer and an internal glass substrate (2), a mother set graph is formed by the metal mesh and a bus electrode group, and the metal mesh conducting layer of the metal mesh employs a magnetron sputtering mode for sputtering a layer of thin copper. The automobile glass is used in the field of the automobile glass.

Description

Technical field: [0001] The invention relates to an automobile glass with electric heating function and a heating method. Background technique: [0002] At present, there are roughly two types of automobile glass with electric heating function on the market: silk screen silver paste automobile rear windshield, electric tungsten wire automobile front windshield. [0003] Screen printing silver paste car rear windshield is a relatively traditional process, the thinnest width of silver paste is about 1mm, the overall printing silver paste material cost is high, and the thicker heating line not only affects the appearance but also has a certain effect on the driver's observation of the environment behind the car block. However, the tungsten wire of the front windshield of electric tungsten wire is about 35 μm cylindrical, and the production cost of the material itself is high, and it needs to be arranged on the glass in a certain order to make laminated glass, and the process i...

Problems solved by technology

In this method, the metal grid is prepared on the film substrate and then laminated between the glasses. The process is relatively complicated, and it is easy to cause film wrinkles during lamination. The patent does not explain the busbar manufacturing method. If the traditional silver paste busbar is used, the cost is still high
