Embodiment Construction

[0039] The following terms are used to describe the glass articles of the present invention.

[0040] A panoramic roof is a type of roof glass that includes a substantial area of ​​the roof over at least a portion of the front and rear seating areas of the vehicle. Panoramic roofs can consist of multiple glazings and can be laminated or monolithic.

[0041] The steps of the above methods must be performed in the order shown, however, additional steps and optional steps that may be required for a specific glazing and coating process may not be shown. The steps must be performed sequentially, but need not be performed immediately after each other, ie the execution of the steps may be separated in space and time.

[0042] Figure 1A and 1B is a schematic diagram of a typical automotive laminated glass cross-section in some embodiments of the present application. The laminate consists of two layers of glass, an outer layer 201 and an inner layer 202, which are permanently bond...

Abstract

Due to the fact that the glass area of a modern vehicle is increased, in particular to a large panoramic glass roof, the use of solar control glass and a coating is greatly increased. The manufacturing cost of the solar glass composition and the coating is very high. While solar coatings are more effective than compositions, it is generally not applicable to single glass, as solar coatings are not durable. A solar coating must be applied to one surface of the inner side of the laminate. Most of these products also introduce undesirable color shifts. The present invention provides a coating that can be used in glass to produce a laminated glass or monolithic glass with a solar controlled neutral gray coating, the coating also having anti-reflection properties and low emissivity.

Description

technical field [0001] The present application relates to the field of solar control automotive glass. Background technique [0002] A trend in automotive design over the past few years has been to increase the total area of ​​glass. An increase in glass area is often accompanied by a reduction in vehicle weight as heavier materials are replaced by glass. This has been a key part of the automotive strategy to meet regulatory demands for higher fleet fuel efficiency and consumer demand for greener vehicles. Furthermore, as car interiors have become smaller, the claustrophobia caused by reduced cabin volume has been counteracted by increasing the area of ​​glazing. Increased view areas and natural light tend to make the cabin more open and airy. As a result, a large panoramic glass roof has become a popular choice for many models. In recent years, acceptance rates in North America and Europe for models offering a panoramic sunroof option have been in the 30 to 40 percent r...
