Problems solved by technology

[0004] At present, there are two main production methods for vacuum glass. One is to pre-set air holes on the plane of the glass plate and seal the air holes after air extraction. This method will leave obvious marks on the finished vacuum glass, which seriously affects The beauty and safety of the vacuum glass plate; another method is to melt and seal the low-melting point glass powder in the vacuum chamber to form a vacuum glass plate. The edge time is longer, and the edge melting cost is higher, and the yield is relatively low, which increases the manufacturing cost of vacuum glass
In addition, vacuum glass generally needs to be heated when sealing the edge of vacuum glass, but tempered glass and laminated glass cannot be heated at all, so the current commonly used methods cannot use tempered glass, laminated glass and other glass to produce vacuum glass

Embodiment 1

[0025] The production method of vacuum glass of the present invention comprises the following steps:

[0026] The first step, stacking the glass: First, along the outer edge of the upper surface of the lower glass plate 5, the inner and outer rings of butyl rubber that are continuously closed are arranged at intervals, and the height of the inner ring butyl rubber 2 and the outer ring butyl rubber 1 is 1.5mm, liquid ultraviolet curable glue 6 is provided between the butyl rubber 2 of the inner ring and the butyl rubber 1 of the outer ring, and supports 7 are placed at intervals along the four sides of the outer butyl rubber of the lower glass plate. The height of the support 7 is greater than that of the butyl rubber, and the compressive strength of the support 7 is less than that of the glass plate. Support points 4 are arranged on the inner side of the butyl rubber 2 of the inner ring, and the support points 4 are evenly spaced along the upper surface of the lower glass plat...

Embodiment 2

[0033] In this embodiment, a circle of continuous closed butyl rubber is arranged at intervals along the outer edge of the upper surface of the lower glass plate, and the inner side of the butyl rubber is provided with liquid ultraviolet curing adhesive, and is placed at intervals along the four sides of the outer side of the butyl rubber. The support, the height of the support is greater than that of the butyl rubber, and the compressive strength of the support is less than that of the glass plate. Support points 4 are arranged on the inner side of the ultraviolet curing glue.

[0034] Others are with embodiment 1.

Embodiment 3

[0036] figure 2 It is the vacuum glass described in Example 3. In this embodiment, the liquid ultraviolet curing adhesive 6 may be coated with metal strips 8 , such as aluminum strips, lead strips or other low-melting alloy strips, and the thickness of the metal strips 8 is smaller than the height of the supporting point 4 . By arranging the metal strip 8, the thickness of the liquid ultraviolet curing adhesive 6 is greatly reduced, and the bonding effect of the ultraviolet curing adhesive 6 is improved.

[0037] Others are with embodiment 1.

Abstract

The invention relates to vacuum glass, and particularly relates to a production method for the vacuum glass and the vacuum glass produced by the method. The production method for the vacuum glass mainly comprises the steps of placing the glass; putting an upper glass plate and a lower glass plate that are well placed already in a vacuum chamber, wherein the vacuum chamber is provided with a press machine; squeezing the well-stacked upper glass plate and lower glass plate by using the press machine; curing liquid bonding adhesive; and the like. The vacuum glass prepared by the method has a good sealing effect, effectively guarantees vacuum degree of the vacuum glass and prolongs service life of the vacuum glass. At the same time, compared with that of a conventional production method for the vacuum glass, the production cost of the production method is greatly reduced. Besides, the method can make the vacuum glass by using toughened glass and laminated glass and is beneficial to wide popularization and application of the vacuum glass.

Description

technical field [0001] The invention relates to a vacuum glass, in particular to a production method of the vacuum glass and the vacuum glass produced by the method. Background technique [0002] Glass plays an increasingly important role in people's lives. Not only is it used in construction, but many daily necessities also use glass as a material. The commonly used glass is transparent and can maintain a good lighting effect. Especially in buildings, double-layer glass is generally used in doors and windows to prevent the indoor temperature from being affected by the external environment for heat preservation and lighting. Although this method It can prevent the convection of hot and cold air indoors and outdoors but cannot isolate the heat conduction of the glass itself, so its heat insulation effect is not very ideal, and the area occupied by the glass on large buildings is getting larger and larger, and the heat loss is also relatively large. Especially when the temper...
