Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to low back temperature heat-insulating fireproof and bulletproof glass. Background Technology

[0002] Glass is ubiquitous in people's daily lives and is widely used in various buildings for wind insulation and light transmission. There are many types of glass, which are generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary materials. For example, colored glass is made by mixing in certain metal oxides or salts to give it its color, tempered glass is made by physical or chemical methods, and some transparent plastics called plexiglass (such as polymethyl methacrylate).

[0003] Bulletproof glass is a type of glass with bulletproof properties, providing users with bulletproof protection. For example, a multi-layered bulletproof glass for automobiles, patent application number CN202323467991.8, includes an inner sheet, an inner interlayer film, a middle sheet, an outer interlayer film, and an outer sheet arranged sequentially from the inside out. The inner sheet has an explosion-proof film attached to its inner side. This patent represents a common type of bulletproof glass for automobiles. However, such bulletproof glass has poor heat insulation and fire resistance, resulting in poor performance and insufficient safety in practical applications. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor heat insulation and fire resistance of existing bulletproof glass, resulting in poor performance and insufficient safety in practical applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Low back temperature heat insulation fireproof and bulletproof glass includes a bulletproof glass layer, and a fireproof glass interlayer is provided on each side of the bulletproof glass layer. The surface of the fireproof glass interlayer is covered with an explosion-proof heat insulation film.

[0007] The bulletproof glass layer includes a first bulletproof glass plate and a second bulletproof glass plate, with a vacuum bubble disposed between the first bulletproof glass plate and the second bulletproof glass plate.

[0008] Preferably, the vacuum bubble has an oval structure.

[0009] Preferably, the vacuum bubble is filled with argon gas.

[0010] Preferably, the explosion-proof heat insulation film includes an adhesive layer that is fixedly bonded to the fireproof glass interlayer, and glass fiber bundles are filled between the adhesive layer and the polycarbonate film.

[0011] Preferably, the polycarbonate coating is fixedly bonded to the glass fiber bundle.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] This utility model, through its composite design, provides glass with basic functions of fire resistance and bulletproofing, while also increasing the heat insulation effect of the glass, preventing bulletproof glass from shattering at high temperatures, and providing users with better bulletproof protection.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3 Low back temperature heat insulation fireproof bulletproof glass includes a bulletproof glass layer 1, a fireproof glass interlayer 2 is provided on each side of the bulletproof glass layer 1, and the surface of the fireproof glass interlayer 2 is covered with an explosion-proof heat insulation film 3.

[0022] The bulletproof glass layer 1 includes a first bulletproof glass plate 101 and a second bulletproof glass plate 102, with a vacuum bubble 103 disposed between the first bulletproof glass plate 101 and the second bulletproof glass plate 102.

[0023] See Figure 3 The vacuum bubble 103 has an oval structure. This design is because the oval structure has better resistance to internal pressure and higher structural strength. It can maintain the stability and reliability of the structure of bulletproof glass plate 101 and bulletproof glass plate 102, and prevent them from breaking under external pressure.

[0024] See Figure 3 The vacuum bubble 103 is filled with argon gas. This is because argon gas has low thermal conductivity and high density, making it suitable for heat insulation in extreme environments such as high temperature, high pressure, and high radiation. Moreover, the high density of argon gas can be used to change the angle of light refraction, thereby changing the position of the user on the glass side in the eyes of outsiders, further improving the user's safety.

[0025] See Figure 4 The explosion-proof heat insulation film 3 includes an adhesive layer 303 that is fixedly bonded to the fireproof glass interlayer 2. Glass fiber bundles 302 are filled between the adhesive layer 303 and the polycarbonate film 301. This arrangement allows the explosion-proof heat insulation film 3 to provide explosion-proof and heat insulation protection for the fireproof glass interlayer 2.

[0026] See Figure 4 The polycarbonate film 301 is fixedly bonded to the glass fiber bundle 302. This arrangement can utilize the glass fiber bundle 302 to improve the structural strength of the explosion-proof heat insulation film 3.

[0027] Working principle: When using this glass, the explosion-proof heat insulation film 3 provides anti-shatter protection for the fireproof glass interlayer 2, and the fireproof glass interlayer 2 provides fire protection for the entire glass, preventing high temperature from damaging the structure of the bulletproof glass layer 1. At the same time, the bulletproof glass layer 1 provides bulletproof and heat insulation functions, thus providing bulletproof protection for users and also isolating heat from both sides of the glass, thereby improving the user experience.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
