Flame retardant structure

Abstract

The invention relates to a flame-retardant structure which is used for being arranged on the surface of a base material. The flame-retardant structure is sequentially provided with an interface layer, a first flame-retardant layer and a second flame-retardant layer. The interface layer is tightly arranged on the surface of the base material, the first flame-retardant layer is arranged on the other face, opposite to the base material, of the interface layer, and the second flame-retardant layer is arranged on the other face, opposite to the interface layer, of the first flame-retardant layer. When a fire disaster occurs, the first flame-retardant layer and the second flame-retardant layer can restrain temperature rise and reduce the combustion rate, so that combustion collapse of a building is delayed, and more escape time is provided. In addition, if the original base material of the building does not have the fireproof effect, the flame-retardant structure can enable the building to meet the fireproof standard under the condition that the base material is not detached.

Description

Technical Field

[0001] This invention relates to a building material structure. Background Technology

[0002] In today's society, governments around the world formulate corresponding fire protection regulations for various buildings to ensure the safety of people's lives. For buildings in different locations, there are corresponding fire protection regulations for the building materials of ceilings, floors, and walls.

[0003] Fire-resistant building materials are those that are not easily combustible or do not easily produce toxic substances when heated in the early stages of a fire. Currently, there are many types of fire-resistant building materials, such as fire-resistant gypsum board, fire-resistant plywood, polyvinyl chloride resin, and fire-retardant coatings.

[0004] However, for today's society, the aforementioned fire-resistant building materials are still insufficient to suppress the temperature in the early stages of a fire, and their delayed combustion time is not enough to allow people inside the building to evacuate safely. In addition, some existing buildings still do not meet fire safety regulations, so if fire-resistant building materials are to be used during renovations, ceilings, floors, or walls must be demolished, resulting in a significant expenditure of money, time, and manpower. Summary of the Invention

[0005] This invention proposes a flame-retardant structure for application on the surface of a substrate, which can suppress and delay the combustion process.

[0006] To achieve the above objectives, the flame-retardant structure proposed in this invention has the following characteristics:

[0007] An interface layer is disposed on the surface of the substrate;

[0008] A first flame-retardant layer is disposed on the other side of the interface layer opposite to the substrate;

[0009] A second flame-retardant layer is disposed on the other side of the first flame-retardant layer opposite to the interface layer.

[0010] Another flame-retardant structure proposed in this invention has the following characteristics:

[0011] An interface layer is disposed on the surface of the substrate;

[0012] A flame-retardant layer is disposed on the other side of the interface layer opposite to the substrate.

[0013] Therefore, the advantage of this invention is that the flame-retardant structure can be disposed on the surface of the substrate and tightly adhered to the substrate through the flame-retardant structure interface layer. In the event of a fire, the flame-retardant structure attached to the substrate surface can inhibit temperature rise and reduce the combustion rate, thereby delaying building collapse and providing more escape time. Furthermore, if the original building substrate does not have fire-resistant properties, the flame-retardant structure can make the building comply with fire safety regulations without removing the substrate.

[0014] As described above in the flame-retardant structure, the material of the interface layer includes epoxy resin, polyaspartic acid ester, latex, or a mixture of latex and cement.

[0015] As described above in the flame-retardant structure, the material of the interface layer contains a flame retardant.

[0016] As described above, the flame-retardant structure includes:

[0017] The material of the first flame-retardant layer includes epoxy resin, flame retardant and mortar;

[0018] The material of the second flame-retardant layer includes epoxy resin and flame retardant.

[0019] As described above, in the flame-retardant structure, the material of the first flame-retardant layer or the material of the second flame-retardant layer contains a smoke suppressant.

[0020] As described above, the flame-retardant structure contains epoxy resin and flame retardant as its material.

[0021] As described above, the flame-retardant structure contains epoxy resin, flame retardant, and mortar as its material.

[0022] As described above, in the flame-retardant structure, the material of the flame-retardant layer contains a smoke suppressant. Attached Figure Description

[0032] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0033] Please refer to Figures 1 to 3This invention proposes a flame-retardant structure for application on the surface of a substrate A, which can inhibit and delay the combustion process. Substrate A is a building material, typically made of concrete or mortar. Substrate A can be used to construct floors, walls, or ceilings of buildings. In a first embodiment, the flame-retardant structure sequentially comprises an interface layer 10, a first flame-retardant layer 21, and a second flame-retardant layer 22.

[0034] Interface layer 10 can be coated on the surface of substrate A, and the material of interface layer 10 may include epoxy resin, polyaspartic acid ester, latex, or a mixture of latex and cement. In addition, the material of interface layer 10 may also include a flame retardant to enhance the flame retardant effect of the flame-retardant structure. A first flame-retardant layer 21 is disposed on the side of interface layer 10 opposite to substrate A, and a second flame-retardant layer 22 is disposed on the side of first flame-retardant layer 21 opposite to interface layer 10. In other words, interface layer 10 is closest to substrate A, while the second flame-retardant layer 22 is furthest from substrate A. The material of the first flame-retardant layer 21 may include epoxy resin, a flame retardant, and mortar, thereby providing not only a flame-retardant effect but also protecting the structural strength of substrate A from damage. The material of the second flame-retardant layer 22 is similar, except that the material of the second flame-retardant layer 22 may include epoxy resin and a flame retardant, and in this embodiment, the material of the second flame-retardant layer 22 does not include mortar. The flame retardant in this embodiment can be a halogen-free flame retardant or a halogenated flame retardant, but is not limited to these. The material of the first flame-retardant layer 21 and / or the material of the second flame-retardant layer 22 can further contain a smoke suppressant to reduce the smoke generated when the first flame-retardant layer 21 or the second flame-retardant layer 22 burns. The materials of the interface layer 10, the first flame-retardant layer 21, and the second flame-retardant layer 22 also contain a curing agent, so that after all the materials are mixed evenly, the epoxy resin in the first flame-retardant layer 21 and the second flame-retardant layer 22 solidifies.

[0035] In the second embodiment, the flame-retardant structure is similar to that in the first embodiment, except that the flame-retardant structure in the second embodiment does not have a first flame-retardant layer 21 and a second flame-retardant layer 22, but has a flame-retardant layer 21A. The material of the flame-retardant layer 21A in the second embodiment is the same as the material of the first flame-retardant layer 21 in the first embodiment. In other words, the material of the flame-retardant layer 21A includes epoxy resin, flame retardant, and mortar, and also has a curing agent, and a smoke suppressant may be added.

[0036] In the third embodiment, the flame-retardant structure is similar to that in the second embodiment, except that the material of the flame-retardant layer 22A in the third embodiment does not contain mortar. In other words, the material of the flame-retardant layer 22A in the third embodiment is the same as that of the second flame-retardant layer 22 in the first embodiment, that is, the material of the flame-retardant layer 22A contains epoxy resin and flame retardant, also has a curing agent, and a smoke suppressant may be added.

[0037] The advantage of this invention is that the flame-retardant structure can be disposed on the surface of the substrate A and is tightly bonded to the substrate A via the flame-retardant structure interface layer 10. In the event of a fire, the flame-retardant structure attached to the surface of the substrate A can suppress the temperature rise and reduce the combustion rate, thereby delaying the building's collapse and providing more escape time. Furthermore, if the original substrate A of the building does not have fire-resistant properties, the flame-retardant structure can make the building comply with fire safety regulations without removing the substrate A.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
