Abstract

The invention relates to the field of laminated glass, particularly a laminated glass with high heat reflectivity and electric heating function applicable to the field of vehicles or construction, more particularly an automobile windshield glass installed on a vehicle. The electrically-heatable low-emissivity coated laminated glass comprises two glass substrates, a middle polymer sandwiched between the two glass substrates, low-emissivity film and a bus, wherein the low-emissivity film is arranged on at least one glass substrate surface in contact with the middle polymer; the bus is distributed on the low-emissivity film; and the bus is a pressure-sensitive adhesive or anisotropic conductive adhesive. According to the electrically-heatable low-emissivity coated laminated glass provided by the invention, the ACF (anisotropic conductive film) or PSA (pressure-sensitive adhesive) is used as the bus in combination with the low-emissivity film to heat the laminated glass, thereby removing frost and melting ice; and thus, compared with the adoption of other buses, the invention simplifies the production technique, is convenient to operate, lowers the material cost and enhances the production efficiency and process yield.

Description

Technical field: [0001] The invention relates to the field of laminated glass, in particular to a laminated glass applied in the vehicle or construction field and having high heat reflectivity and electric heating function, especially an automobile windshield installed on the vehicle. Background technique: [0002] In cold weather, car glass and building glass are often prone to frost and ice, which affects the sight of people in cars and buildings. In particular, car windshields must provide drivers with a good view in order to ensure driving safety and Comfort, so it is necessary to require the car windshield to have the function of defrosting and melting ice. This function of defrosting and melting ice can be realized by electrically heating the windshield of the car, while the traditional laminated glass is composed of two transparent glasses and an intermediate polymer sandwiched between the two transparent glasses. Laminated glass cannot achieve the above functions by...
