Embodiment 1

[0062] Soda lime silicate float glass with a thickness of 2.1mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. Two pieces The transparent nano-film and the conductive low-emissivity (Low-E) coating including two silver layers were deposited on the glass substrate respectively, and the conductive low-emissivity (Low-E) coating was completed and then printed on the glass substrate by screen printing. Two layers of ink containing silver nanoparticles are arranged on the conductive low-emissivity coating, and after the ink is dried at 200-250°C, the two glass substrates are matched. It is pasted on two inks containing silver nanoparticles to form the first electrode and the second electrode, and then a piece of PVB film with a thickness of 0.76 mm is sandwiched in the middle. After the initial pressure and high pressure process of the film and the installation of ac...

Embodiment 2～4

[0068] Soda lime silicate float glass with a thickness of 1.6mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. The transparent nano-film and the conductive low-emissivity coating in Table 2 are respectively deposited on the two surfaces of the glass substrate of mm, wherein the conductive low-emissivity (Low-E) coating is completed and then screen-printed on the conductive low-emissivity coating Arrange two inks containing silver nanoparticles, and after drying the inks at 200-250°C, match the two glass substrates. Form the first electrode and the second electrode on the printing ink of silver nanoparticle, then sandwich a piece of PVB film with a thickness of 0.76 millimeters in the middle, and make the interlayer of the present invention through the initial pressure and high pressure process of lamination and the annex installation of other processes glass pl...

Abstract

The invention relates to the field of head-up display technologies, particularly relates to head-up display sandwich glass on automobiles, and particularly discloses head-up display sandwich glass. Electric heating can be carried out by the aid of a conducting low-emissivity coating of the head-up display sandwich glass. The head-up display sandwich glass comprises an inner glass plate, an outer glass plate and a middle membrane. A transparent nanometer film capable of reflecting P polarized light is deposited on the surface, which is farthest to the middle membrane, of the inner glass plate, the conducting low-emissivity coating is deposited on the surface, which is the closest to the middle membrane, of the outer glass plate or on the surface, which is the closest to the middle membrane, of the inner glass plate, and a first electrode and a second electrode which are used for being connected with external power sources are arranged on the conducting low-emissivity coating. The head-up display sandwich glass has the advantages that the head-up display sandwich glass is excellent in heat-insulation performance; the head-up display sandwich glass is basically free of ghosting phenomena, and high-definition head-up display effects can be realized by the head-up display sandwich glass; the two electrodes can be communicated with the external power sources, and accordingly, the head-up display sandwich glass can have an electric heating function and further can have defrosting and demisting functions.

Description

[0001] Technical field: [0002] The present invention relates to the field of head-up display technology, in particular to laminated glass for head-up display on automobiles, in particular to a laminated glass for head-up display that can be electrically heated with a conductive low-emissivity coating, wherein the conductive low-emissivity coating can not only reflect infrared rays, but also can Cooperate with electrodes for electric heating. [0003] Background technique: [0004] With the development of science and technology, and people's demand for additional functions of the front windshield of the car is becoming more and more high-end, the front windshield of the car is endowed with more and more functions, such as the head-up display (HUD) function, electric heating and defrosting Fog function, reflective infrared heat insulation function and UV protection function, etc. In the prior art, the functions of the front windshield glass of the automobile are relatively sim...
