Abstract
The invention provides composite heat-insulating fire-proof glass with high integral adhesion, which has a sandwich structure consisting of at least two glass layers and a fire-proof adhesive layer between the two adjacent glass layers, wherein at least one glass layer is made of the glass obtained by chemical treatment; the chemical treatment is carried out by placing flat glass in a molten salt tank of an exchange furnace and then performing ion exchange on the flat glass and the sylvite-containing molten salt in the molten salt tank; and the molten salt also contains one or more alkali metal antimonates. The composite heat-insulating fire-proof glass with high integral adhesion of the invention greatly improves the fire resistance; the adhesion of the foamed fire-proof adhesive layer is also greatly improved; and even if the flushing is performed under a high temperature condition, the integrity of the glass is maintained well, so that the glass has good fire resistance and heat insulation performance in actual fire prevention and fire fighting operation.
Description
Technical field
The present invention relates to the method for manufacture of the high composite heat-insulating fire-proof glass of a kind of integral adhesion and the new composite heat-insulating fire-proof glass that obtains through this method of manufacture.
Background technology
Flame resistant glass is meant under regulation fire testing condition; The special glass that can keep its integrity and thermal insulation; It can be after fire takes place; Being kept perfectly property, and formation as far as possible for a long time is effectively fire prevention, Smoke prevention, radioprotective barrier together, is the requisite safe building materials of Highrise buildings, communal facility; At present, flame resistant glass mainly contains following several kinds both at home and abroad:
A kind of flame resistant glass is a single-sheet fire-resistant glass, wherein is typically borosilicate single-sheet fire-resistant glass and caesium potassium single-sheet fire-resistant glass:
The remarkable fire resistance of borosilicate single-sheet fire-resistant glass stems from its very low thermal expansivity, is merely 4 * 10
-6(20-300 ℃) is than low 2 to 3 times of simple glass (silicate glass).In addition, the borosilicate single-sheet fire-resistant glass also has high softening-point, outstanding speciality such as fabulous thermal-shock resistance and viscosity.Therefore, when fire took place, the borosilicate single-sheet fire-resistant glass was difficult for expanding cracked, thereby meets the requirements of the fire prevention time limit.
Another kind is that caesium potassium single-sheet fire-resistant glass is to be handled and physical toughened being made through particular chemical by common float glass.Such glass keeps the naked light and poisonous, the obnoxious flavour of fire integrity, blocking-up counter-fire face in the regular hour, but does not possess the adiabatic effect of thermal insulation.Belong to C class flame resistant glass.
Another kind is the heat insulation type flame resistant glass:
When fire took place, the glass that can satisfy fire integrity and thermal insulation within a certain period of time was called the heat insulation type flame resistant glass.Flame can produce high heat in combustion processes, and sees through glass with thermal radiation and heat conducting mode, and the temperature that makes glass carry on the back fiery face constantly raises.When acquiring a certain degree, heat can make people or combustiblematerials under the situation that does not touch flame, is burnt or ignites.The heat insulation type flame resistant glass injures in order to make escape and rescue personnel exempt from heat just, and the destructiveness of fire is reduced to minimum design.Its special fire-retardant material can absorb heat significantly, thereby it is controlled in the standard value, and the most effective safeguard protection is provided.
The heat insulation type flame resistant glass comprises the compound insulating fire-retarding glass and the heat insulation type flame resistant glass etc. that is in the milk.
Compound insulating fire-retarding glass is composited by two-layer or former one deck that attaches of multiple glazing or multi-layer fireproofing plastic clip layer usually.When fire takes place; Side towards the fire glass bursts after meeting high temperature very soon; Fire prevention plastic clip layer is about about ten times of foaming and intumescings in succession, and the high calorie that absorbs flame in a large number and brought, and form the White-opalescent Formica; Its hard degree can guarantee fire integrity, and the porous structure makes it have heat-blocking action.Therefore, compound insulating fire-retarding glass both can intercept high temperature effectively, can completely cut off flame, smog and toxic gas again, can in fire, avoid causing personnel's fear.
Grouting type flame resistant glass is by after the sealing of two sheet glass process, pours into inorganic fire glue therebetween and is made.When fire took place, side towards the fire glass burst after meeting high temperature very soon, and the inorganic fire glue-line scleroma rapidly that central, clear is gelatin forms a White-opalescent fire-proof heat insulation board, and the high calorie that absorbs flame in a large number and brought.When stoping propagation of flame, also stop the high temperature fiery face conduction of supporting or opposing.
Wherein, composite fireproof glass is effectively aspect heat insulation, fire prevention.Now existing a lot of related patent U.S. Patent No. (application) disclose the method for making this composite fireproof glass.
Such as, U.S. Pat 4,190,698 disclose prescription and the method for manufacture that is used for composite fireproof glass.The open WO01/70495 of international application also discloses a kind of method of manufacture of refractory glass.
Summary of the invention
