Description
Technical Field
[0001] The invention belongs to the technical field of fireproof glass, and particularly relates to a composite isolation fireproof glass, a manufacturing method thereof and an application thereof. Background Art
[0002] With the development of building levels and the increasing demand for light by people, more and more shopping malls and office buildings have adopted glass curtain walls. In order to prevent glass from penetrating and hurting people in case of accidents such as fires, most of the existing technologies adopt glass with fireproof and heat-insulating properties. However, the existing technologies only focus on obvious indicators such as fire resistance limit and heat insulation, ignoring the high-static electricity environment (due to high-temperature ionization of air) accompanied by fires, which easily causes soot particles to be adsorbed on the glass surface, forming an opaque conductive film layer, thereby reducing the visibility of emergency signs and the command of others, and making it difficult for trapped people to know the effective escape direction in the first time.
[0003] For example, in the "A fireproof and heat-insulating glass and a preparation process thereof" disclosed in the patent document "CN119319703A", its technical solution forms a three-dimensional network structure through a double-crosslinked gel monomer to improve fireproof performance, ignoring that when the temperature is too high, the glass will be in a static electricity environment and easily adsorb dust, reducing the light transmittance of the glass, and further reducing the visibility of emergency signs and the command of others, and further reducing the escape probability.

[0023] The composite fireproof glass provided by the present invention can protect the human body in a high-temperature fire environment. On the one hand, when a fire just breaks out, the first normal temperature static conductive layer and the second normal temperature static conductive layer establish a stable charge dissipation channel, and can continuously export the accumulated static charges at the initial stage of the fire, thereby maintaining the light transmittance stability of the surface of the composite fireproof glass, preventing the static electric field generated by the high temperature on the composite fireproof glass, and further preventing dust from being adsorbed on the surface of the composite fireproof glass. When the temperature exceeds 300°C, the active ions released by the softening of the first ion release layer and the second ion release layer can react with the static charges generated by high-temperature ionization to effectively eliminate the static adsorption effect on the glass surface, avoid the formation of a conductive shielding layer of soot particles on the glass surface, not only maintain the light transmittance stability of the surface of the composite fireproof glass in an extreme environment, but also achieve the intelligent matching of the electric field strength and the temperature field through the gradient-distributed conductive network, so that the light transmittance of the emergency sign in a high-temperature environment is improved, and the secondary escape risk caused by static blindness of traditional fireproof glass under complex fire conditions is solved.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0029] Please refer to Figure 1-2 ;
[0030] The present invention discloses a composite isolation fireproof glass, aiming to avoid the glass generating an electrostatic field due to ionized air in a high-temperature environment, thereby absorbing dust and covering the glass, reducing the visibility of people escaping in a fire, and enabling the escaping people to better see the light emitted by the escape signs. The composite isolation fireproof glass includes an outer glass layer 1, an inner glass layer 2, a gradient temperature-sensitive layer 1 3, a gradient temperature-sensitive layer 2 4, and a fireproof interlayer 5. One side of the outer glass layer 1 is connected to one side of the gradient temperature-sensitive layer 1 3. In this embodiment, the connection manner between the outer glass layer 1 and the gradient temperature-sensitive layer 1 3 is not limited and can be formed by compounding under high temperature and high pressure conditions. The other side of the gradient temperature-sensitive layer 1 3 is connected to one side of the fireproof interlayer 5. The other side of the fireproof interlayer 5 is connected to one side of the gradient temperature-sensitive layer 2 4. The other side of the gradient temperature-sensitive layer 2 4 is connected to the inner glass layer 2;
[0031] The gradient temperature-sensitive layer 1 3 includes a normal temperature static conductive layer 1 31 and an ion release layer 1 32. When the temperature of the ion release layer 1 32 is greater than 300 °C, the ion release layer 1 32 softens and releases ions. The ions in this embodiment refer to metal positive ions. One side of the normal temperature static conductive layer 1 31 is connected to one side of the outer glass layer 1, and the other side of the normal temperature static conductive layer 1 31 is connected to the ion release layer 1 32. The gradient temperature-sensitive layer 2 4 includes a normal temperature static conductive layer 2 41 and an ion release layer 2 42. When the temperature of the ion release layer 2 42 is greater than 300 °C, the ion release layer 2 42 softens and releases ions. One side of the normal temperature static conductive layer 2 41 is connected to the inner glass layer 2, and the other side of the normal temperature static conductive layer 2 41 is connected to the ion release layer 2 42.
[0032] Specifically, the composite fireproof and insulating glass of the present invention can be used on the first floor of a shopping mall or on the outer glass of a safety indicator light; at normal temperature, the outer glass layer 1 and the inner glass layer 2 have strength, enabling the composite fireproof glass to maintain stability. Assuming a fire occurs on one side of the inner glass layer 2, when the temperature range of the fire is from 100 °C to 300 °C, at this time, the inner glass layer 2 ionizes the air due to high temperature and will ionize electrons. The normal-temperature static-conducting layer two 41 can stably conduct the electrons to the ground. In the temperature range of 100 °C to 300 °C of the fire, the static charge of the inner glass layer two can be continuously conducted out, thereby maintaining the light-transmitting stability of the surface of the composite fireproof glass. More specifically, the normal-temperature static-conducting layer two 41 adopts a vertically penetrating structure, that is, a certain density of through-holes are penetrated in the inner-layer glass 2, and then a silver-graphene composite slurry is filled in the through-holes, and a conductive film is formed after heat treatment. In addition, when the inner glass layer 2 is manufactured, a conductive net is attached to the outer surface, and the conductive net is electrically connected to the conductive film. It should be noted that in this embodiment, the wire of the conductive net is extremely thin, and it is difficult for the human eye to observe from a distance. The conductive net is embedded in the surface of the inner glass layer 2, and the surface is flat; thereby, due to the conductive characteristic of the normal-temperature conductive layer two 41 at normal temperature, the static electric field generated by the composite fireproof glass due to high temperature is prevented, and thus the dust adsorption on the surface of the composite fireproof glass is prevented, enabling the people escaping on the side of the inner glass layer 2 to conveniently see the escape indicator light, or to follow the gestures of the command personnel on the side of the outer glass layer 1 to choose the direction to escape. When the temperature exceeds 300 °C, the normal-temperature conductive layer two is difficult to continue conducting static electricity, and the active ions softened and released by the ion release layer two 42 can react with the static charge generated by high-temperature ionization. More specifically, when the temperature is greater than 300 °C, the normal-temperature conductive layer two stops its conductive performance due to its own characteristics; in this embodiment, the normal-temperature conductive layer two can be preferably a nano-antimony tin oxide layer. Taking the nano-antimony tin oxide layer as an example in this embodiment, the nano-antimony tin oxide layer loses its conductivity when the temperature is greater than 300 °C. It should be noted that the through-holes penetrate the ion release layer two, causing the viscosity of the ion release layer two to decrease; thereby releasing ions, and the pre-buried metal ions are neutralized with the electrons on the outer surface of the inner glass layer through the conductive film in the through-holes, effectively eliminating the static electricity adsorption effect on the glass surface, avoiding the formation of a conductive shielding layer by soot particles on the glass surface, not only maintaining the light-transmitting stability of the surface of the composite fireproof glass in an extreme environment, but also realizing the intelligent matching of the electric field strength and the temperature field through the gradient-distributed conductive network, improving the light transmittance of the emergency sign in a high-temperature environment, and solving the secondary escape risk caused by static electricity blindness of traditional fireproof glass under complex fire conditions.
[0033] In this embodiment, the first ion release layer 32 includes a phosphate glass sub-layer 321. A plurality of micro-cavities 6 are arrayed within the phosphate glass sub-layer 321. The micro-cavities 6 include main cavities 61 and branch channels 62. A three-dimensional connected ion transport network is formed by a number of main cavities 61 and a number of branch channels 62. Zirconium phosphate nanosheets are provided within the micro-cavities 6, and a metal ion substance with controllable release is disposed on the zirconium phosphate nanosheets.
[0034] Specifically, when the temperature is greater than 300 °C, the phosphate glass sub-layer 321 begins to soften, the walls of the micro-cavities 6 undergo plastic deformation, and the cross-sectional area of the connection between the main cavities 61 and the branch channels 62 expands by 35%. At this time, the interlayer spacing of the zirconium phosphate nanosheets expands, thereby releasing the bonded metal ions. When the temperature is maintained in the range of 300 - 350 °C, the released metal ions form a dynamic charge neutralization layer on the surface of the phosphate glass sub-layer 321, thereby neutralizing static charges in a high-temperature environment, preventing dust adsorption, and enhancing the light transmittance stability at high temperatures.
[0035] In this embodiment, the fireproof interlayer 5 includes a transparent high-temperature resistant film 51, a fireproof heat-absorbing gel layer 52, and a transparent ceramic coating 53. The first ion release layer 32 is bonded to the transparent high-temperature resistant film 51, the transparent high-temperature resistant film 51 is bonded to the fireproof heat-absorbing gel layer 52, the fireproof heat-absorbing gel layer 52 is bonded to the transparent ceramic coating 53, and the transparent ceramic coating 53 is bonded to the second ion release layer 42.
[0036] Specifically, in actual use, the transparent high-temperature resistant film 51 can maintain structural stability in a high-temperature environment, playing a preliminary heat insulation and protection role; the fireproof heat-absorbing gel layer 52 rapidly absorbs a large amount of heat when encountering high temperatures, significantly reducing the temperature of the back fire surface; the transparent ceramic coating 53 hardens into a solid opaque fireproof barrier at high temperatures, effectively blocking the further transmission of flames and heat radiation. It can not only achieve a synergistic effect in a high-temperature environment, keeping the temperature of the back fire surface of the glass within a safe range, with an average not exceeding 140 °C, but also prevent burns or spontaneous combustion of people or combustibles caused by high temperatures, thereby greatly improving the overall performance of the fireproof glass and ensuring personal and property safety.
[0037] In this embodiment, the aperture diameter of the microcavity 6 in the phosphate glass sub-layer 321 is 8 μm - 12 μm, preferably 10 μm. Compared with the aperture diameter of the microcavity 6 being 8 μm, the 10 μm aperture diameter increases the cross-sectional area of the main cavity 61 and thus reduces the ion diffusion resistance. Compared with the aperture diameter of the microcavity 6 being 12 μm, the wall thickness of the 10 μm aperture diameter is more stable; the aspect ratio of the microcavity 6 in the phosphate glass sub-layer 321 is 1:5 to 1:8, preferably 1:5; when the aspect ratio of the microcavity 6 is 1:5, the etching process difficulty is significantly reduced; the wall thickness of the microcavity 6 in the phosphate glass sub-layer 321 is less than 2 μm. Further, the ambient temperature static conductive layer 1 includes a nano antimony tin oxide layer, and the thickness of the nano antimony tin oxide layer is 30 - 70 nm. The nano antimony tin oxide layer with a thickness of preferably 50 nm can better balance the static electricity rate and the light transmittance.

[0043] Step 5, vacuum impregnate the zirconium phosphate nanosheet suspension into the microcavity 6 and electrophoretically deposit metal ion active substances;

[0046] Step 8, anneal at 450 °C under nitrogen protection for 2 hours to activate the three-dimensional ion transport network.
