Examples

Referring to fig. 1, an embodiment of the present application provides a high light transmittance vacuum glass, including:

a first glass layer 1;

the second glass layer is arranged in parallel with the first glass layer 1 and has a distance with the first glass layer 1;

the sealing part 2 is arranged at the periphery of the first glass layer 1 and the second glass layer and seals the space in the interval, and the space is a negative pressure space; and

support piece, support piece are chemical toughened glass 3, and chemical toughened glass 3 sets up in the interval, the relative both sides of chemical toughened glass 3 respectively with first glass layer 1, second glass layer butt.

It should be noted that the first glass layer 1 and the second glass layer are mainly described for distinction, and the two structures may be generally the same as shown in fig. 1, or may be different. In fig. 1 only the reference numeral 1 is indicated for the sake of illustration.

It will be appreciated that the first and second plies of

glass

1 and 1 may be more than one ply when necessary, but may be sealed together with the seal 2 after being placed side by side. For example, the sealing portion 2 of the present embodiment is sealed by using a sealing material, and when the number of layers of glass is different, the sealing portion can be sealed by using an appropriate amount of sealing material according to the size of the sealed area. The sealing material can be an inorganic material, a metal material or an inorganic metal composite material.

As for the chemically tempered glass 3, more specifically, the chemically tempered glass 3 of the present application has a thickness of 0.1 to 1.5mm.

The cross-sectional area of the chemically tempered glass 3 is 0.6-4mm ² 。

The specific thickness and section size can be selected according to the size of the space between the first glass layer 1 and the second glass layer, the size of the first glass layer 1 and the second glass layer and the strength requirement during supporting, and the light transmittance can meet the requirements as long as the support can be met.

Alternatively, the cross-sectional shape of the chemically tempered glass 3 may be triangular, square (shown in fig. 2) or circular (shown in fig. 3). Of course, this is only an example of the present embodiment, and other chemically tempered glass 3 having a shape that can be stably supported without affecting light transmittance may be used as the support. For example, the chemically tempered glass 3 having an elliptical shape, an oblong shape, or the like may be used.

The light transmittance of the chemical toughened glass 3 is more than or equal to 85%, so that the light transmittance of the finally-formed high-transmittance vacuum glass meets the requirement.

In the embodiment, the chemically tempered glass 3 is fixedly connected with the first glass layer 1 and/or the second glass layer through a transparent adhesive. In detail, during manufacturing, the first glass layer 1 or the second glass layer may be selected to fix the chemically tempered glass 3, or the transparent adhesive may be coated on both sides of the chemically tempered glass 3, and then the chemically tempered glass is fixed to the first glass layer 1 and the second glass layer. In this embodiment, the transparent adhesive used is an ultraviolet light curable adhesive.

With continuing reference to fig. 1, the number of the chemically tempered glass 3 of the present embodiment is plural. It is to be understood that when the size of the product to be produced is small, it is also possible to consider using a single chemically tempered glass 3, and there is no limitation that a plurality is necessary. When the single chemically tempered glass 3 is used, it is considered that the chemically tempered glass has a large cross-sectional size to ensure stable support between the first glass layer 1 and the second glass layer.

In the present embodiment, the circumferential corner position of the chemically tempered glass 3 is transited by an arc-shaped wall. That is, the portion having the sharp corner needs to be ground and polished, so that the sharp corner portion has an arc-shaped wall structure, and the support process is prevented from being broken.

Further, the chemically tempered glass 3 of the present embodiment is aluminum silicate glass, and the above-mentioned index parameters related to the chemically tempered glass 3 are also applicable to the aluminum silicate glass. Such as thickness, cross-sectional area, light transmission, and profile, etc. The chemical toughened glass 3 is simple to manufacture, and the manufacturing method comprises the following steps:

(1) Chemically tempering a glass sheet (e.g., a 0.5mm thick soda lime float glass) in a solution at a temperature above 400 ℃;

(2) Cutting the glass into individual glass pieces, for example, 1mm by 1mm squares;

(3) Removing sharp corners at the periphery of the glass sheet by grinding and polishing to form a glass supporting column (namely a supporting piece);

(4) And detecting the surface flatness of the glass support column.

It can be seen that the support member of the present application is simple to manufacture, and can be easily and clearly understood and implemented by those skilled in the art, as compared to the obscure prior art.

The principle of the embodiment is as follows:

the common vacuum glass is supported by metal, and can meet the use requirement in daily use, but the vacuum glass obviously cannot meet the requirement in environments with higher requirements on heat insulation, particularly in some environments with visual requirements. In addition, although some vacuum glass uses glass, the vacuum glass is not shown more, and the implementation of the scheme by the person skilled in the art is still not easy, and is not suitable for practical application.

In view of this, this application provides a high printing opacity vacuum glass.

It should be noted that the high transmittance referred to in the present embodiment mainly means that, compared to the vacuum glass using metal support in the prior art, the chemically tempered glass 3 is used as the support member, and does not block light like metal support, so that the transmittance of the whole high transmittance vacuum glass is higher than that of the common vacuum glass using metal support.

The utility model provides a high printing opacity vacuum glass puts into chemical toughened glass 3 as support piece with the interval between first glass layer 1 and the second glass layer to adopt sealing material to form sealing portion 2 back all around, through the hole evacuation of reserving, make and form the negative pressure cavity and obtain between first glass layer 1 and the second glass layer. The whole high-light-transmission vacuum glass is simple to manufacture and can be normally realized by the personnel in the field.

The chemical toughened glass 3 that this application adopted has utilized chemical toughening technology to reinforce glass's intensity, then reduces the microcrack through grinding technology, has strengthened supporting strength to make this support piece can have sufficient intensity, under 0.1 mpa/square centimeter's atmospheric pressure, also difficult cracked, thereby can replace the metal support, stably support between first glass layer 1 and second glass layer. And rely on self more than or equal to 85% luminousness, can not exert an influence to whole high printing opacity vacuum glass's light transmissivity to compared with the vacuum glass who adopts metal-support, the holistic luminousness of this application has still obtained the promotion. In addition, the heat conductivity of the chemical toughened glass 3 is much lower than that of the metal support, so that the heat insulation performance can be improved to a certain degree, the light transmission and heat insulation properties of the vacuum glass are well enhanced, and the vacuum glass has a good practical value.

To sum up, the high printing opacity vacuum glass of this application can stably support between first glass layer 1 and second glass layer through adopting chemical toughened glass 3 as support piece, and compared the ordinary vacuum glass who adopts the metal-support, its luminousness is higher to because chemical toughened glass 3's heat conductivity is less than the metal-support, whole high printing opacity vacuum glass's heat-proof quality also is superior to ordinary vacuum glass, has effectively solved current problem.
