Problems solved by technology

[0005] Through the above analysis, the problems and defects of the existing technology are: the existing insulating glass is easily affected by the temperature change of the external environment during use, causing the central part of the glass to sag and the glass surface to deform, which affects the appearance of the glass and the mirror effect is very poor. Poor, and affect heat preservation and heat insulation performance, greatly shorten the service life of insulating glass

preparation example Construction

[0069] like Figure 13 As shown, the preparation method of the negative pressure insulating glass provided by the embodiment of the present invention includes:

[0070] S101: Make glass: Cut two pieces of glass of the same size according to the shape and size of the hollow glass to be produced, and then grind, clean and dry, and if tempered glass is required, it must be tempered;

[0071] S102: Cut spacers or make spacer frames, and make supports: select spacer bars of appropriate material and size, cut into spacer bars of corresponding lengths or make spacer frames of corresponding sizes according to the size of the glass; make supports of corresponding shapes and heights ;

[0072] S103: Fix the spacer or spacer frame: apply sealant or structural glue or double-sided tape on the bonding surface of the spacer or glass, and bond the spacer to the glass to form a closed frame; or Apply sealant or structural adhesive or double-sided tape on the bonding surface of the spacer fr...

Embodiment 1

[0080] Embodiment 1: as figure 1 and Figure 10 As shown, a kind of negative pressure insulating glass comprises glass 1, spacer bar 2, first sealing layer 3, second sealing layer 4, third sealing layer 5 and support 7, cut two according to the size of the hollow glass made Glass 1 of the same size, and carry out edging and cleaning; when tempered glass is needed, enter the tempering furnace for tempering treatment; adopt existing insulating glass spacers, preferably warm edge strips, according to the size and shape of glass 1 and the first The glue thickness of the structural glue used in the sealing layer 4 is according to Figure 10 The length of each spacer 2 is determined by the placement method, the rectangular insulating glass uses 4 spacer 2, and the special-shaped insulating glass determines the number of spacer 2 according to the shape and size of the glass; Figure 10 The two ends of the four spacer bars 2 in the center are respectively cut into 45 degree angles s...

Embodiment 2

[0081] Embodiment 2: as figure 2 and Figure 11 As shown, a negative pressure insulating glass, including glass 1, spacer 2, first sealing layer 3, second sealing layer 4, fourth sealing layer 6 and support 7, is basically the same as embodiment 1, the difference The placement of the spacer bar 2 is as follows: Figure 11 As shown, the upper openings of the spacers 2 vertically placed on the left and right sides are exposed (the size of the exposure can be adjusted by the size of the cut corner), which facilitates the perfusion of molecular sieves and saves the process of punching holes on the spacers 2 , which saves equipment investment and processing time; the support 7 adopts a strip support, such as a spacer, and is bonded and fixed with a sealant; the first sealing layer 3 adopts a continuous bonding method, and continuous bonding has better Sealing effect; the difference is also that the fourth sealing layer 6 is used to replace the third sealing layer 5, the fourth s...

Abstract

The invention belongs to the technical field of hollow glass production, and discloses negative-pressure hollow glass, a manufacturing method and application. The negative-pressure hollow glass comprises glass, spacing bars, molecular sieves, supporting materials, sealing layers bonded between the glass and the spacing bars, and sealing layers bonded between the glass and the peripheries of the spacing bars. A hollow layer is vacuumized to be in a negative pressure state, the air pressure of the hollow layer is smaller than the external pressure all the time in the use process of the hollow glass, the breathing phenomenon of the hollow glass is eliminated, an edge sealing structure is not subjected to repeated acting force generated by the breathing phenomenon, and the service life of theedge sealing structure and the service life of the hollow glass can be remarkably prolonged; due to the fact that the supporting materials are arranged in the hollow layer, the glass cannot deform, agood mirror surface effect can be kept all the time, and the appearance of a building is more attractive; and the spacing bars are adopted to replace spacing frames to be directly bonded on the glass,the technological process of manufacturing the spacing frames is omitted, mechanical and automatic production is facilitated, the placement speed is high, and the installation precision is high.

Description

technical field [0001] The invention belongs to the technical field of hollow glass production, and in particular relates to a negative pressure hollow glass, a manufacturing method and an application thereof. Background technique [0002] At present: my country's building energy consumption has accounted for about 1 / 3 of the total energy consumption of the whole society. Building energy conservation is an important measure for my country to ensure national energy security and build a conservation-oriented and environment-friendly society. Insulating glass is a glass product in which two or more pieces of glass are evenly spaced at the edge by a spacer frame, and bonded and sealed with the periphery of the glass on the outside of the spacer frame, so that a hollow layer of dry gas is formed between the glass layers. Insulating glass is a building energy-saving product with good heat insulation and sound insulation performance. At present, the application of insulating glass ...
