Fireproof and energy-saving glass green building materials

Abstract

This new type of fireproof and energy-saving glass green building material has two sides facing opposite directions and multiple layers of glass. The multiple layers of glass are arranged at intervals from one side to the other side, and any two adjacent glass layers are connected by a fireproof adhesive layer. At least one of the glass layers is made of colored glass. In the event of a fire, the fireproof adhesive layer reacts at high temperatures to form a structure that blocks the spread of fire and the conduction of high temperatures. Under normal conditions, by using colored glass layers to reduce light transmittance and absorb solar radiation such as visible light and ultraviolet rays of specific wavelengths, the heat absorbed by indoor air from solar radiation can be reduced, keeping the indoor temperature more suitable and thus reducing the use of air conditioning. It has both fireproof and energy-saving effects.

Description

Fireproof and energy-saving glass green building materials Technical Field

[0001] This invention relates to glass components, and more particularly to a fire-resistant and energy-saving green building material. Prior Technology

[0002] As population density increases daily, some residents live in high-rise buildings. However, in the event of a fire, escape and rescue in high-rise buildings are more difficult and dangerous. Therefore, in order to prolong the rescue and escape time, in addition to using fire-resistant materials to construct the wall structure, fire-resistant glass is also used to delay the spread of the fire and block high temperatures to the greatest extent possible.

[0003] Existing fire-resistant glass typically consists of two layers of glass with a fire-resistant material, such as fire-retardant sealant, filling the space between them. This sealant absorbs heat when exposed to high temperatures, transforming into a hard, opaque insulating layer to block high temperatures. However, before absorbing heat and transforming, the fire-retardant sealant only provides slight protection against infrared and ultraviolet radiation from the sun. Furthermore, the glass structure next to the sealant is generally still made of clear glass with high light transmittance. Under normal conditions, indoor air can still easily absorb solar radiation and heat up. Therefore, the heat insulation performance of existing fire-resistant glass under normal conditions still needs improvement. Summary of the Invention

[0004] To address the limited heat insulation performance of existing fireproof glass under normal conditions, the purpose of this invention is to propose a fireproof and energy-saving green building material that also possesses good heat insulation performance under normal conditions.

[0005] The fire-resistant and energy-saving glass green building material proposed to solve this technical problem has two sides facing opposite directions and includes: A plurality of glass layers, which are arranged at intervals from one side to the other, any two adjacent glass layers are connected by a fire-retardant adhesive layer, and at least one of the glass layers is a layer made of colored glass.

[0006] The improved effects of this new technology are as follows: In the event of a fire, the fire-resistant adhesive layer between the multiple glass layers can absorb the heat energy of the fire and transform into a highly fire-resistant and rigid structure, thereby preventing the spread of fire. In normal times, the use of colored glass layers can reduce the absorption of solar radiation heat energy by the indoor air, thereby maintaining a more suitable temperature in the indoor space and reducing the use of air conditioning. Thus, this provides a glass green building material that combines fire resistance and energy saving. Simple Explanation of the Diagram

Figure 2 is a partial side cross-sectional view of the second preferred embodiment of the present invention. Figure 3 is a partial side cross-sectional view of the third preferred embodiment of the present invention. Figure 4 is a partial side cross-sectional view of the fourth preferred embodiment of the present invention. Implementation

[0008] To gain a detailed understanding of the technical features and practical effects of this invention, and to enable its implementation, the preferred embodiment shown in the figures is described in detail below:

[0009] As shown in Figure 1, the first preferred embodiment of the fireproof and energy-saving glass green building material 10 of the present invention has two opposite sides and includes a plurality of glass layers located between the two sides.

[0010] As shown in Figure 1, the two sides are an outer side 11 and an inner side 12. When the fireproof and energy-saving glass green building material 10 is installed, the outer side 11 faces the outside and the inner side 12 faces the inside. The multiple glass layers are arranged from the outer side 11 to the inner side 12 at intervals.

[0011] Specifically, the outer side 11 and the inner side 12 are positioned opposite each other on a thickness direction T of the fireproof and energy-saving glass green building material 10. The plurality of glass layers are arranged at intervals along the thickness direction T. In the first preferred embodiment of the present invention, an outer glass layer 20A, an intermediate glass layer 20B and an inner glass layer 20C are arranged sequentially from the outer side 11 toward the inner side 12.

[0012] As shown in Figure 1, a fire-retardant adhesive layer 30 is provided between any two adjacent glass layers. In the first preferred embodiment of this invention, there is a fire-retardant adhesive layer 30 between the outer glass layer 20A and the middle glass layer 20B, and between the middle glass layer 20B and the inner glass layer 20C. Adjacent glass layers are connected together by the fire-retardant adhesive layer 30, thereby the multiple glass layers arranged at intervals can be connected to form a multi-layer glass structure.

[0013] The aforementioned fireproof adhesive layer 30 can be a nano-ceramic layer made of a composite material containing silica gel. In the high temperature of a fire, the silica gel will decompose and react with other additives to form a hard ceramic shell with extremely high fire resistance. It can remain unmelted in a fire and prevent the spread of fire. Alternatively, the aforementioned fireproof adhesive layer 30 can also be an organic-inorganic hybrid gel layer. The organic gel component can be polyacrylamide, and the inorganic component can be sodium chloride, magnesium chloride, etc. It can absorb the high-temperature radiant heat energy in the fire and transform into a hard and opaque foam structure, thereby blocking the radiant heat energy of the fire.

[0014] As shown in Figure 1, in this invention, at least one of the plurality of glass layers is a layer made of colored glass. The aforementioned colored glass is formed by adding metal oxides during the manufacturing process. Specifically, it can be made using the float glass method. When metal oxides are added to the glass raw material, when light shines on the glass layer, the metal ions therein will absorb light of a specific wavelength range, allowing only the remaining light to pass through, thereby visually forming the corresponding color.

[0015] For example, by adding substances such as chromium oxide (Cr2O3) and ferrous oxide (FeO) to molten glass, a glass layer that absorbs red and blue light and allows green light such as dark green and French green to pass through, thus appearing green, can be produced. By adding substances such as cobalt oxide (CoO, Co2O3) and copper oxide (CuO), a glass layer that absorbs other colors of light and allows blue light such as dark blue and light blue to appear blue can be produced. By adding substances such as nickel oxide (NiO), a brownish-red glass layer can be produced. These are just a few examples.

[0016] In the first preferred embodiment of this invention, the intermediate glass layer 20B and the inner glass layer 20C are layers made of common clear glass, and the outer glass layer 20A is a layer made of colored glass. Because it is made of metal oxide, the metal ions therein have the ability to absorb visible light and ultraviolet light in specific wavelength ranges. The outer glass layer 20A has a lower light transmittance than clear glass and can improve the ability to block solar radiation, thus greatly reducing the heat energy of solar radiation absorbed by indoor air.

[0017] Through the above-mentioned technical features, in the event of a fire, the fireproof adhesive layer 30 between the multiple glass layers can absorb the heat energy of the fire and transform it into a highly fire-resistant and rigid structure, thereby preventing the spread of fire. In normal times, the use of colored glass layers can also reduce the amount of solar radiation heat absorbed by the indoor air, thereby maintaining a more suitable temperature in the indoor space and reducing the use of air conditioning. Thus, a glass green building material with both fireproof and energy-saving effects can be provided.

[0018] As shown in Figure 1, each glass layer has a thickness T1 along the thickness direction T, and each fireproof adhesive layer 30 has a thickness T2. In practice, the thickness T1 of each glass layer can be uniformly 5 cm (mm), and the thickness T2 of the fireproof adhesive layer 30 can also be uniformly 5 cm. In actual installation, the thickness T1 of the multiple glass layers can be designed differently to block sounds of different frequencies and reduce resonance, thereby achieving better sound insulation. For example, the outer glass layer 20A can be designed to be thicker to resist external wind pressure, while the middle glass layer 20B and the inner glass layer 20C can be designed to be thinner.

[0019] In the first preferred embodiment of this invention, the outer glass layer 20A is made of colored glass. When exposed to sunlight, the outermost glass layer 20A can directly absorb solar radiation of specific wavelengths, such as visible light and ultraviolet rays. At the same time, the outer glass layer 20A is still separated from the indoor air by the intermediate glass layer 20B, the inner glass layer 20C, and the fireproof adhesive layer 30. After the outer glass layer 20A heats up, it is less likely to conduct heat into the room. This has the best theoretical effect in terms of avoiding indoor heating and energy saving.

[0020] Figure 2 shows a second preferred embodiment of the fireproof and energy-saving glass green building material 10A of the present invention. The difference between this embodiment and the first preferred embodiment is that, in the aforementioned three glass layers, the middle glass layer 20B is made of colored glass, while the outer glass layer 20A and the inner glass layer 20C are made of clear glass. In another embodiment, the inner glass layer 20C may also be made of colored glass. The present invention does not particularly limit the use of colored glass layers.

[0021] In the second preferred embodiment of this invention, the intermediate glass layer 20B is made of colored glass. When it absorbs the heat energy of solar radiation and heats up, and cracks due to thermal stress, the outer glass layer 20A and the inner glass layer 20C on both sides will not immediately shatter and fall off because they are located in the center of the structure. When personnel notice the crack in the intermediate glass layer 20B in the center, it can be replaced as soon as possible, reducing the risk of accidents caused by glass breakage.

[0022] Figure 3 shows the third preferred embodiment of the fireproof and energy-saving glass green building material 10A of the present invention. The difference between it and the first preferred embodiment of the present invention is that, in the aforementioned three glass layers, the middle glass layer 20B and the inner glass layer 20C are both made of colored glass, while the outer glass layer 20A is made of clear glass. Through the two layers of colored glass, the overall light transmittance can be further reduced, and the effect of absorbing solar radiation and preventing the indoor temperature from rising can be improved.

[0023] In other embodiments, the outer glass layer 20A and the middle glass layer 20B, the outer glass layer 20A and the inner glass layer 20C, or even all three glass layers can be made of colored glass. The specific choice depends on the relevant requirements such as cost, heat insulation, and durability. The number of colored glass layers is not limited to the aforementioned preferred embodiments of the present invention.

[0024] Furthermore, if, as in the aforementioned embodiments, the glass layer comprises at least two or more layers made of colored glass, then the at least two or more glass layers have the same color. In this way, the aforementioned effects of reducing overall light transmittance and preventing indoor temperature from rising can be achieved. At the same time, the at least two or more glass layers can also prevent the absorption of all wavelengths of visible light, ultraviolet rays, and other solar radiation, while still maintaining a certain degree of light transmittance.

[0025] Figure 4 shows the fourth preferred embodiment of the fireproof and energy-saving glass green building material 10C of the present invention. The difference between the fourth and fifth preferred embodiments of the present invention is that a plurality of intermediate glass layers 20B are included between the outer glass layer 20A and the inner glass layer 20C, and the outer glass layer 20A and at least one intermediate glass layer 20B are layers made of colored glass.

[0026] In the fourth preferred embodiment of this invention, more layers of glass and fireproof adhesive layer 30 between adjacent glass layers are used to further improve fireproof and heat insulation effects. It can be applied in places with high accident risk, such as laboratories and power distribution rooms. In the event of a fire, it can better prevent the spread of fire, greatly increase escape time, and improve safety.

[0027] In other embodiments, the number of intermediate glass layers 20B can be determined according to different requirements such as fire resistance, heat insulation performance, production cost, and working hours. The intermediate glass layers 20B can also be two or four or more, and the corresponding number can be different. The thickness of the intermediate glass layers 20B and the fireproof adhesive layer 30 between them can also be adjusted accordingly. This invention does not impose specific restrictions on the specific number or size.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical solution provided by the present invention shall still fall within the scope of the technical solution of the present invention.
