Description
Technical Field
The utility model relates to fireproof glass with fireproof blocking heat insulation films, and belongs to the technical field of building glass.
Background
With the improvement of the living standard of people and the high-speed development of construction industry, the common glass can not meet the social requirement, the glass door and window area of the building is larger and larger, the building glass is gradually developed from the past purely serving as a lighting and decoration material to the directions of safety fire prevention, heat preservation, heat insulation, sound insulation, noise reduction, intelligent light control and the like, and various safety glass and special glass gradually enter the front of the glass industry. Fireproof glass is one of the members of safety glass, and is favored by people in a step by virtue of the properties of the fireproof glass, such as fire retarding and heat insulating properties, in addition to the properties of common glass. When a fire disaster occurs, the fire disaster recovery device delays the spreading time of the fire disaster, creates important conditions for rescuing people, property and buildings, and reduces the loss to the maximum extent. In some important occasions with special requirements, the foot lifting effect is exerted.
Along with the national standard of the fireproof glass, the fireproof glass is increasingly applied to building parts such as large-scale public building partitions, fireproof partitions, outdoor curtain walls and the like, and the fireproof glass is characterized by transparency, so that the harmony and unification of building fireproof and building aesthetics are met to the greatest extent.
The prior fireproof glass has various forms, the adopted materials and process methods and the realization effects are also quite different, and the prior fireproof glass has relatively large application in China and is simply divided into two main types according to the fireproof performance of the fireproof glass: fire-resistant heat-insulating fireproof glass: the delay spreading time is 30-180 minutes, the traditional grouting fireproof glass is mainly fireproof glass which is mainly prepared by grouting fireproof liquid between two or more pieces of glass and meets the requirements of fireproof integrity and fireproof heat insulation property; monolithic fire resistant glass of the second type: the delay spreading time is 30-120 minutes, the toughened glass product (named cesium potassium fireproof glass) produced by adopting a special process method with common glass as a substrate is mainly fireproof glass which only meets the fire-resistant integrity requirement.
The production process of the heat-insulating fireproof glass mainly comprises a grouting method, and the principle is that a transparent gel (fireproof liquid) with flame retardant property is condensed between two pieces of glass 2, as shown in figures 1-2. The fire-proof glass production process mainly includes grouting method, and its principle is that a transparent gel (fire-proof liquid) with fire-retarding property is coagulated between two pieces of glass, and when the gel is exposed to high temp. it is undergone the process of decomposition and heat-absorbing reaction, and can be used for absorbing a large quantity of heat energy, and can be changed into foamed opaque material, so that it possesses good heat-insulating action. The processing technology comprises the following steps:
1. scribing according to the processing size of the glass 2;
2. edging and cleaning the glass 2;
3. surrounding edge 1 of fire-proof glass with glue and 15-20mm glass 2, and leaving a pouring solution port;
4. after the glass 2 is fixed after the surrounding edge, injecting fireproof (heat-insulating solution) liquid 3 to the pouring opening of the surrounding semi-finished glass;
5. drying in the shade (generally for 72 hours) at a certain temperature and humidity, the fireproof (heat-insulating) solution 3 forms a gel;
and 6, finally sealing, cleaning and finishing the fireproof glass product.
The fireproof glass can be kept at a certain time without cracking, namely fragments can not be peeled off after cracking, and flame can be separated to prevent flame spreading. If the flame retardant is added into the gel, flame retardant gas can be emitted at high temperature, and the gel has flame retardant and fire extinguishing functions; when a fire disaster occurs, the glass contacted with the fire is firstly burst after a few minutes, and the interlayer material is successively changed into a layer of bubble-shaped substance to form a thick and dense bubble-shaped fire-resistant heat-insulating layer, and fragments of the glass contacted with the fire are always stuck on the bubble-shaped layer until the fragments are melted, so that the glass on the back fire surface is always in a loved and shielded state. In the fire protection test, the average temperature rise of the glass back surface does not exceed 140 ℃. However, the glass manufacturing process with the structure is only suitable for planar glass, and is low in process efficiency and inconvenient to process for curved surface and anisotropic glass.
Because of poor weather resistance of grouting heat-insulating fireproof glass, a large number of large glass groups such as Japanese AGC company, german schott company and French saint-gobain company are actively researching single-piece fireproof glass. The fireproof glass has good weather resistance, never fades and is not devitrified, and the characteristics of crystal clear glass are fully reflected.
The special single-sheet fireproof glass refers to glass with the adopted glass substrate as special components, and is not glass with general flat glass components. It mainly includes borosilicate fire-proof glass, aluminosilicate fire-proof glass, microcrystal fire-proof glass and sodium-calcium material high-quality float glass whose softening temperature is above 800 deg.C. The common key characteristics are as follows: the glass has high softening point, is generally above 800 ℃, has low thermal expansion coefficient, can not crack or deform under strong flame due to high temperature, and especially has the characteristics of high mechanical strength, fracture resistance, high compressive strength, good chemical stability and physical and mechanical properties. The glass has the advantages of high softening temperature and small thermal expansion coefficient, but the production cost of the special material fireproof glass (boron, aluminosilicate fireproof glass and microcrystalline fireproof glass) is high, the product is unstable and has poor weather resistance and strong contingency, the glass is not ideal fireproof glass, and the glass is difficult to be accepted and accepted by people in market, and the price is up to 1000 American gold per square meter.
In the prior art, a glue clamping method is also adopted to prepare the fireproof glass, as shown in fig. 3 and 4, a glue film 4 is added between the glass 2, and the defect that the edge of the glue clamping film is easy to ignite and self-burn can occur after the structure is long. Therefore, it is necessary to relate to a structure of high temperature refractory insulation to solve the problem of easy burning of open fire.
