Description

A see-through highly reflective coated glass

technical field

The utility model belongs to the field of glass manufacture and application, in particular to a see-through high-reflection coated glass used in special monitoring places, interior decoration or hidden displays, rearview mirrors and other fields.

Background technique

At present, the highest light reflectance of domestic glass curtain wall is 37% to 38%. The reflectivity of silver-gray mirror glass is relatively high, and the reflectance of general mirror glass is 20% to 30%. Excessively high reflectivity of architectural glass curtain walls will cause certain light pollution. The current national standard "Design Standards for Energy Conservation of Public Buildings" stipulates that the reflectivity of all wall and window glass must be controlled below 30%. Therefore, many cities in China use curtain walls The maximum reflectivity limit for glass is specified. See-through high-reflection coated glass is not suitable for glass curtain walls constructed in accordance with the "Design Standards for Energy Conservation of Public Buildings". It is generally used in special surveillance places, interior decoration or hidden displays, rearview mirrors and other fields.

The transmission of light by glass depends on the three parts of reflection, absorption and transmission of glass. If high transmittance is used, the reflectance will inevitably decrease. If colored glass is used, excessive absorption will affect the transmission and reflection of light. , if you want to get more reflection, you will lose part of the transmission and absorption. At present, the transmittance of mirrors in daily life is zero. Except for a small amount of absorption by the glass substrate body, the rest is all reflected light. See-through high-reflection coated glass is mainly based on the principles of low absorption, low transmission, and high reflection. A high-reflection film is set on the glass surface, and with the help of outdoor light or light, a mirror effect is formed when observing outdoors. .

See-through high-reflection coated glass is usually coated with a high-reflection film on the surface of organic materials such as PET (polyethylene terephthalate, polyethylene terephthalate), and then attach the film to the surface of the glass substrate. Due to the poor UV resistance and low hardness of organic materials, it leads to poor scratch resistance, easy degumming or bubble phenomenon, and the process quality and high cost caused by artificial film sticking restrict the paste on the surface of the glass substrate. The development of high reflective film technology.

Considering the many shortcomings of the above-mentioned film pasting methods, there is currently another way in the industry to produce see-through high-reflection coated glass, which is produced by an online method. In a float glass production line, only one type of glass substrate can be used to deposit a high-reflection film, and the choice of glass substrates has great limitations. If a high-reflection film is to be deposited on different glass substrates, the production cost is relatively high; and The film layer of the see-through high-reflection coated glass produced by the online method is set on the first surface of the glass substrate (usually the observer watches from the outdoor to the indoor, the glass surface that can be touched by hand is called the outdoor surface, and the surface opposite to the outdoor surface is located The indoor glass surface is called the indoor surface; the outdoor surface is also called the first surface, and the surfaces of the glass sheets arranged in sequence from the outdoor surface to the indoor surface are respectively called the second surface, the third surface, and the fourth surface... ..), in the process of cleaning the glass, it is easy to corrode the high reflection film due to the cleaning solution, thus affecting the reflection effect. In addition, the silane raw material used in the deposition process of the on-line method is a highly toxic chemical product, which has high cost and cannot meet environmental protection requirements.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of see-through high-reflection coated glass, which can choose the color, transmittance and thickness of the glass substrate arbitrarily, the high-reflection film is not easy to be corroded or damaged, and belongs to environmental protection glass.

The embodiment of the utility model is realized in this way, a kind of see-through highly reflective coated glass has a glass substrate and a high reflective film deposited on the glass substrate, and the high reflective film is deposited on the indoor surface of the glass substrate or deposited on the inside of the glass substrate.

Since the above-mentioned glass adopts the off-line method to deposit the high-reflection film, the color, transmittance and thickness of the glass substrate can be arbitrarily selected without being affected by the glass production line, and the off-line method can avoid the use of highly toxic and costly chemical products. It belongs to environmentally friendly glass; in addition, the high reflection film of the above glass is deposited on the indoor surface of the glass substrate or inside the glass substrate. Therefore, the high reflection film will not be corroded or damaged by the cleaning solution when cleaning the glass, and the service life of the glass is longer.
