Abstract
The utility model relates to flameproof hollow glass which comprises two layers of glass substrates that are overlapped up and down, wherein a frame space bar is arranged between the two layers of glass substrates and is adhered with the two layers of glass substrates, the frame space bar is internally provided with a closed space, and at least one flameproof glass layer is arranged in the two layers of glass substrates. The utility model improves the heat preservation and insulation property of the common flameproof glass, has the advantages of simple manufacture, lower cost, and good reliability, and is suitable for industrial production.
Description
Technical field
The utility model belongs to glass deep processing field, particularly relates to a kind of fire prevention double glazing.
Background technology
Physical toughened principle is glass to be cooled off immediately fast the glass molecular structure is changed after heat, forms compressive stress layer at glass surface, thereby improves strength of glass.The principle of chemical tempering is by K+ that contains high density and Cs+, displaces Na+ in the glass at the upper layer of simple glass, because the radius of K+ and Cs+ much larger than the radius of Na+, will be increased in the stress that glass surface produces.The injection disperse of a large amount of impurity at high temperature can produce disperse phase, produces dispersion-strengthened, makes surface strengthening.The bearing stress of simple glass is generally 15～65MPa; The bearing stress of physical toughened glass is generally at 70～180MPa; Flame resistant glass is physical toughened again by first chemical tempering, and the toughened glass that its bearing stress is produced than traditional technology exceeds about 100～150MPa.Existing flame resistant glass is divided into single-sheet fire-resistant glass and composite fireproof glass by structural area, and composite fireproof glass adopts the structure of laminated glass, so only improved the bulk strength of flame resistant glass, does not have the performance of heat-insulation and heat-preservation.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of fire prevention double glazing, has improved the heat preservation and insulation of common flame resistant glass, have simultaneously make simple, cost is lower, the advantage of good reliability and suitable suitability for industrialized production.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of fire prevention double glazing, comprise superimposed layer glass substrate up and down, be provided with the shaped as frame spacer bar between the layer glass substrate, shaped as frame spacer bar and layer glass substrate are bonding, form enclosed space in the shaped as frame spacer bar, having one deck in the described layer glass substrate at least is flame resistant glass.
One deck of above-mentioned layer glass substrate is a flame resistant glass, and another layer is a sheet glass.
Above-mentioned flame resistant glass is---dry back high temperature ion-exchange---remove salt surfactant after heat---the stage by stage physical toughened acquisition of air cooling method by surface spraying sylvite or cesiated salt solution by common float glass.
The technical solution of the utility model has following advantage:
1, improved the heat preservation and insulation of flame resistant glass;
2, improved physical toughened heating mode, the staged intensification by control stage by stage prevents that substrate from bursting.
3, technology is simple and easy to control, reliability is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of fire prevention double glazing as shown in Figure 1, comprise superimposed layer glass substrate up and down, be provided with shaped as frame spacer bar 3 between the layer glass substrate, shaped as frame spacer bar 3 is bonding with the layer glass substrate, form enclosed space 4 in the shaped as frame spacer bar 3, one deck is a flame resistant glass 1 in the described layer glass substrate, and another layer is a sheet glass 2.
When making flame resistant glass, adopt common float glass, press the certain size cutting, cleaning-drying as substrate.Preparation potassiumphosphate (or saltpetre or cesium nitrate) solution adds a certain amount of thickening material to improve its viscosity, evenly sprays on two surfaces of substrate with pistol.Vacuumize with dry and remove the surface adsorption salinity, send into process furnace, heat up in three stages, the fs temperature is controlled at 200 ℃～300 ℃, keeps half an hour; The subordinate phase temperature is controlled at 400 ℃～500 ℃, keeps half an hour; The phase III temperature is controlled at 650 ℃～700 ℃, keeps 20 minutes.Send into air-cooling chamber, back and forth cooled off ten minutes, promptly obtain the flame resistant glass substrate.
Prepare hollow aluminum strip, be bent into rectangle spacer bar 3 with the same dimensions of substrate with bending press, then to the inner perfusion of aluminium frame butyl rubber.Next use spacer bar 3 that the substrate of same size specification and a slice float glass (sheet glass) are separated, use the seal gum edge sealing after closing sheet hot pressing, promptly obtain finished product after the curing.
Claims (2)
- One kind the fire prevention double glazing, it is characterized in that, comprise superimposed layer glass substrate up and down, be provided with shaped as frame spacer bar (3) between the layer glass substrate, shaped as frame spacer bar (3) is bonding with the layer glass substrate, form enclosed space (4) in the shaped as frame spacer bar (3), having one deck in the described layer glass substrate at least is flame resistant glass (1).
- 2. a kind of fire prevention double glazing according to claim 1 is characterized in that, one deck of described layer glass substrate is flame resistant glass (1), and another layer is sheet glass (2).
