Embodiment Construction

[0020] A preparation method of vacuum glass, the preparation steps are:

[0021] Step 1. First take two pieces of glass of equal size. Both pieces of glass can be made of white glass. In order to improve the heat insulation effect, a combination of one piece of white glass and one piece of LOW-E glass can also be used. Set a semicircular notch with a radius of 4-6mm at the corresponding position on the edge of the selected two pieces of glass, generally set at 5mm, and prepare it for later use;

[0022] Step 2: Take a piece of glass that has been processed in Step 1, and use an adhesive to set support points and glass seals on the glass. The supporting point is columnar, and its cross section can be circular, square or other shapes. Stick the support points in the middle of the glass in an array, and stick the glass seal around the edge of the glass. Be careful not to go beyond the edge. Leave a distance of 8-12mm, that is, the distance between the outer edge of the glass sea...

Abstract

The invention discloses a method for preparing a vacuum glass, which comprises the following steps of: taking two glasses with semicircular gaps processed on the edges, sticking a supporting point on the middle part of one glass, sticking glass strips on the edges of four sides, arranging air extraction needles at the reserved openings of the glass strips by using adhesive, overlaying and sticking the two set glasses, filling the adhesive into a groove formed by the edges of the two glasses for two times, vacuumizing the cavity between the two glasses by using a vacuum pump through the air extraction needles, and finally, melting the heads of the air extraction needles at the temperature of between 1,800 and 2,000 DEG C to seal so as to obtain a product. The vacuum glass prepared by adopting the technical scheme can effectively prevent vacuum recession, and the service life of the vacuum glass is prolonged. Four sides of the glasses of two layers are supported and sealed by using the glass strips, and the sealing layer formed by the filled adhesive and the glass strips improve the strength for supporting, so the distance between the two glasses can be enlarged, the suction of the two glasses after vacuumizing is prevented, and the heat insulation and sound insulation properties of the vacuum glass are improved.

Description

technical field [0001] The invention relates to a glass, in particular to a vacuum glass with a vacuum interlayer and a preparation method thereof. Background technique [0002] Vacuum glass has excellent heat insulation and sound insulation properties, and vacuum glass has great development prospects in today's environment of energy saving and emission reduction. Most of the vacuum glass in the prior art adopts a form in which a support is arranged between two pieces of glass, and the edge of the glass is sealed with a sealant. In order to ensure the sealing effect of the edge of the glass, the thickness of the sealant should not be too large, otherwise the insufficient strength of the sealant will cause air leakage. Therefore, the distance between the two pieces of glass in this structure is very close. After the hole is drawn, the two pieces of glass will be attracted to each other when they are bent and deformed due to the effect of air pressure, which greatly reduces t...
