[0011] Through the cooperation between the substrate, the fire suppression unit, the baffle and the bolts, when a fire occurs inside the building during use, after the temperature near the substrate rises to a certain height, the plug will become a molten state. At this time, the vertical hole is in a connected state, and the solution inside the second cavity will flow into the first cavity through the vertical hole. After the solution contacts the particles, a certain amount of carbon dioxide gas will be generated, and this gas can be sprayed to the outside of the baffle through the micropores.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a high fire-resistant metal plate, including a substrate 1, the substrate 1 and the baffle 3 are both made of metal steel, the front and rear surfaces of the substrate 1 are provided with a fire suppression unit 2, the outer side of the fire suppression unit 2 is provided with a baffle 3, the baffle 3 is threadedly connected to the substrate 1 through a bolt 4, the fire suppression unit 2 includes a post 201, a first cavity 202, particles 203, a second cavity 204, a solution 205, a vertical hole 206, a plug 207 and a micropore 208, the two post plates 201 are divided into The first cavity 202 is provided with particles 203, which are aluminum sulfate particles. A second cavity 204 is provided above the first cavity 202. A solution 205 is provided inside the second cavity 204. The solution 205 is a sodium bicarbonate solution. A vertical hole 206 is provided between the second cavity 204 and the first cavity 202. A plug 207 is provided inside. The plug 207 is made of paraffin wax, also known as crystalline wax, which is usually a white, colorless and odorless waxy solid. It melts at 47°C-64°C. The melting point can be controlled by adding polyolefin additives. When the temperature rises above the melting point of the plug 207, the plug 207 melts and flows downward. The vertical hole 206 is in a connected state. After the solution 207 contacts the particles 203, a chemical reaction occurs to produce a large amount of carbon dioxide. A plurality of micropores 208 are evenly opened on the outer surface of the baffle 3. The micropores 208 are arranged on the outer surface of the baffle 3. 08 passes through the baffle 3 and a part of the plate 201 in sequence. The micropore 208 is connected to the interior of the first cavity 202, but is not connected to the second cavity 204. The plate 201 is connected to the substrate 1 through the adhesive 5. The adhesive 5 is a polyurethane adhesive that can improve the stability between the plate 201 and the substrate 1. A coating 6 is provided on the outside of the micropore 208. The coating 6 is arranged on the outer surface of the baffle 3. The coating 6 is made of the same material as the plug 207, which can prevent the particles 203 from flowing out of the micropore 208.

[0021] First, two stickers 201 are respectively embedded in the front and back surfaces of the base fabric 1, and the baffle 3 is connected to the substrate 1 by bolts 4, so that it can be used as a load-bearing board for construction. During use, the substrate 1 has excellent metal rigidity and can meet the support operation of a certain weight. When a fire occurs inside the building during use, the temperature near the substrate 1 rises to a certain height, and the plug 207 will become a molten state. At this time, the vertical hole 206 is in a connected state, and the solution 205 in the second cavity 204 will flow into the first cavity 202 through the vertical hole 206. After the solution 205 contacts the particles 203, a certain amount of carbon dioxide gas will be generated, and this gas can be sprayed to the outside of the baffle 3 through the micropores 208. The sprayed carbon dioxide gas can suppress the open flame near the substrate 1, reduce the temperature rise rate of the substrate 1, and then prolong the rigidity duration of the substrate 1 when a fire occurs, which reduces the probability of collapse of the local part of the building due to insufficient rigidity of the supporting plate. It has strong practical performance and is easy to promote and use.
