Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass technology, specifically to a fire-resistant and safe nanocrystalline glass. Background Technology
[0002] With the increasing demands for material performance in industries such as construction and electronics, nanocrystalline glass has attracted widespread attention as a new type of high-performance material. Nanocrystalline glass, also known as glass-ceramic, is a polycrystalline solid material formed by inducing the precipitation of a large number of nanoscale crystals within a glass matrix through a specific heat treatment process. However, a drawback is that during a fire, due to the sealing and heat insulation properties of glass, the outer layer heats up rapidly, while the inner layer heats up relatively slowly, resulting in a significant temperature difference between the inside and outside of the glass, which can easily lead to cracking. To address these drawbacks, existing technologies... (Chinese patent application number: 202320597649.0, authorized announcement date: 2023-10-13) discloses a fireproof and heat-insulating glass. The outer frame of the heat-insulating glass is made of a heat-conducting material. In the event of a fire, it absorbs heat and conducts it to the inner side of the outer glass through a heat-conducting mesh, so that the temperature inside and outside of the outer glass quickly becomes the same, avoiding sudden temperature rise that could cause the glass to crack. The inner frame is made of a heat-insulating material to prevent heat from the outside from being absorbed to the inside. The heat-conducting mesh is made of a fine and dense high heat-conducting material, achieving "invisibility" and heat conduction effects without affecting light transmittance and aesthetics.
[0003] Existing technology transfers heat to the inner side of the outer glass layer through an outer frame, allowing the temperatures of the inner and outer glass layers to quickly become uniform and preventing sudden temperature increases that could cause the glass to crack. However, this type of glass has poor fire resistance, meaning that it cannot effectively prevent heat transfer when the temperature is too high during a fire, causing the glass temperature to rise sharply and crack. Furthermore, when subjected to external impact, the glass is prone to shattering into sharp fragments that may fly out and cause cuts, punctures, or other injuries to people nearby, resulting in low safety. Therefore, we have proposed a fire-resistant and safe nanocrystalline glass that can effectively solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a fire-resistant and safe nanocrystalline glass to solve the problems mentioned in the background art, such as poor fire resistance, inability to effectively prevent heat transfer when the fire temperature is too high, resulting in a rapid increase in glass temperature and cracking, and easy breakage of the glass into sharp fragments when subjected to external impact, which may fly out and cause cuts, punctures and other injuries to people around, resulting in low safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-resistant and safe nanocrystalline glass, comprising a nanocrystalline glass body, wherein a heat-insulating interlayer is provided inside the nanocrystalline glass body; a protective layer is connected to the outer surface of the nanocrystalline glass body, and a buffer support is provided on the upper and lower surfaces of the nanocrystalline glass body; a protrusion is connected between the buffer support and the protective layer; and a fire-retardant coating is applied to the side of the buffer support away from the nanocrystalline glass body.
[0006] Preferably, the heat insulation interlayer is made of polyurethane foam material, and the interior of the heat insulation interlayer is filled with inert gas to improve the fire resistance of the nanocrystalline glass body.
[0007] Preferably, the two buffer supports are embedded in the outer surface of the nanocrystalline glass body, and the buffer supports are made of polycarbonate material.
[0008] Preferably, the protective layer is made of polymethyl methacrylate and is bonded to the nanocrystalline glass body and the buffer support by an adhesive.
[0009] Preferably, the four protrusions are distributed at equal angles at the corner between the protective layer and the buffer support, and the protrusions are made of polytetrafluoroethylene material and are embedded between the protective layer and the buffer support.
[0010] Preferably, the upper and lower ends of the nanocrystalline glass body are respectively connected to a first reinforcing wire and a second reinforcing wire, and the first reinforcing wire and the second reinforcing wire form a mesh structure design.
[0011] Preferably, the first reinforcing wire and the second reinforcing wire are distributed alternately at equal intervals inside the nanocrystalline glass body. The first reinforcing wire is made of carbon fiber material, and the second reinforcing wire is made of glass fiber material.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This fire-resistant and safe nanocrystalline glass adopts a novel structural design, the specific details of which are as follows:
[0013] (1) When a fire occurs, the fireproof coating can expand to form a heat insulation layer, preventing heat from being transferred to the nanocrystalline glass body. At the same time, it isolates oxygen, delaying the heating and damage of the nanocrystalline glass body. Meanwhile, the inert gas (such as argon, krypton, etc.) filled inside the heat insulation interlayer can effectively reduce heat transfer and improve the heat insulation and fire resistance of the nanocrystalline glass body. Furthermore, the heat insulation interlayer is made of polyurethane foam material, which has good sealing properties to prevent gas leakage.
[0014] (2) When the glass is impacted, the buffer bracket can absorb and buffer part of the impact force, reduce the direct force on the nanocrystalline glass body, and the protective layer can absorb and disperse the impact energy, thereby improving the overall impact resistance. Furthermore, by using multiple protrusions set between the protective layer and the buffer bracket, the pressure on the nanocrystalline glass body can be evenly distributed between the protective layer and the buffer bracket, avoiding excessive local pressure, so that the force on each part of the nanocrystalline glass body is more balanced, reducing glass damage caused by stress concentration and extending the service life of the nanocrystalline glass body.
[0015] (3) The first and second reinforcing wires distributed inside the nanocrystalline glass body, and the first and second reinforcing wires forming a mesh structure, can play the role of bearing load and hindering crack propagation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5 The present invention provides the following technical solution: a fire-resistant and safe nanocrystalline glass;
[0024] Example 1: To address the problems of poor fire resistance in existing technologies, which prevent effective heat transfer during high-temperature fires, leading to a rapid increase in glass temperature and subsequent cracking, and the tendency for the glass to shatter into sharp fragments upon impact that could scatter and cause cuts, punctures, or other injuries to bystanders, thus posing a safety risk, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 5 As shown, the device includes a nanocrystalline glass body 1, with an internal heat-insulating layer 2 made of polyurethane foam and filled with inert gas to improve the fire resistance of the nanocrystalline glass body 1. A protective layer 3 is connected to the outer surface of the nanocrystalline glass body 1, and buffer supports 4 are provided on both the upper and lower surfaces. Protrusions 6 connect the buffer supports 4 to the protective layer 3, with four protrusions 6 evenly distributed at the corners between the protective layer 3 and the buffer supports 4. The protrusions 6 are made of polytetrafluoroethylene and are embedded between the protective layer 3 and the buffer supports 4. A fire-retardant coating 5 is applied to the side of the buffer supports 4 away from the nanocrystalline glass body 1.
[0025] In the event of a fire, the fire-retardant coating 5 can expand to form a heat insulation layer, preventing heat from being transferred to the nanocrystalline glass body 1. At the same time, it isolates oxygen, delaying the heating and damage of the nanocrystalline glass body 1. Meanwhile, the inert gas (such as argon, krypton, etc.) filled inside the heat insulation interlayer 2 can effectively reduce heat transfer and improve the heat insulation and fire resistance of the nanocrystalline glass body 1.
[0026] Example 2: Unlike Example 1, this example utilizes the protective layer 3 and the buffer support 4 to improve the impact resistance of the nanocrystalline glass body 1. See details... Figure 1 , Figure 2 and Figure 5 As shown, two buffer supports 4 are embedded on the outer surface of the nanocrystalline glass body 1, and the buffer supports 4 are made of polycarbonate material. The protective layer 3 is made of polymethyl methacrylate material, and the protective layer 3 is bonded between the nanocrystalline glass body 1 and the buffer supports 4 by adhesive.
[0027] When the nanocrystalline glass body 1 is impacted, the buffer bracket 4 can absorb and buffer part of the impact force, reducing the direct force borne by the nanocrystalline glass body 1. The protective layer 3 can absorb and disperse the impact energy, thereby improving the overall impact resistance. At the same time, the multiple protrusions 6 set between the protective layer 3 and the buffer bracket 4 can evenly distribute the pressure borne by the nanocrystalline glass body 1 between the protective layer 3 and the buffer bracket 4, avoiding excessive local pressure. This makes the force on each part of the nanocrystalline glass body 1 more balanced, reducing damage to the nanocrystalline glass body 1 caused by stress concentration and extending the service life of the nanocrystalline glass body 1.
[0028] Example 3: Unlike Example 2, this example utilizes the first reinforcing wire 7 and the second reinforcing wire 8 to bear the load and hinder crack propagation. See details... Figure 4 As shown, the upper and lower ends of the nanocrystalline glass body 1 are respectively connected to the first reinforcing wire 7 and the second reinforcing wire 8, and the first reinforcing wire 7 and the second reinforcing wire 8 form a mesh structure design. The first reinforcing wire 7 and the second reinforcing wire 8 are distributed at equal intervals and alternately inside the nanocrystalline glass body 1. The first reinforcing wire 7 is made of carbon fiber material, and the second reinforcing wire 8 is made of glass fiber material.
[0029] The first reinforcing wire 7 and the second reinforcing wire 8 are distributed inside the nanocrystalline glass body 1, and the first reinforcing wire 7 and the second reinforcing wire 8 form a mesh structure, which can play the role of bearing load and hindering crack propagation.
