[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.
[0019] Combine Figure 1-Figure 3The utility model provides a firewall panel, including a panel body 1, which wraps the internal core material as an integral structure. The panel body 1 uses a high-strength lightweight composite material to ensure that it has good mechanical strength and weather resistance. The interior of the panel body 1 is a hollow structure, and a grid plate 11 is connected to the center position of the panel body 1. The grid plate 11 divides the interior of the panel body 1 into multiple spaces. The interior of the grid plate 11 is filled with a fireproof layer 2, which can expand to form a protective barrier to prevent further spread of flames and heat. A heat insulation layer 3 is provided on both sides of the grid plate 11. The heat insulation layer 3 has a heat insulation effect and protects the internal structure of the panel body 1 from being affected by external temperature changes.
[0020] The outer surface of the panel body 1 is evenly sprayed with a layer of nano-scale fireproof coating with a thickness of about 0.1mm to 0.5mm, which plays a primary fireproof function. The side walls of the insulation layer 3 close to the panel body 1 are coated with a waterproof and breathable membrane 31. The waterproof and breathable membrane 31 is wrapped around the outside of the insulation layer 3 to ensure that it is tightly fitted with the insulation layer 3. The waterproof and breathable membrane 31 ensures the stability and service life of the panel in a humid environment. The insulation layer 3 is made of microporous calcium silicate. Microporous calcium silicate is a highly efficient thermal insulation material with a large number of tiny pores inside. These pores can effectively reduce heat conduction, thereby achieving a good thermal insulation effect. In addition, microporous calcium silicate also has a certain sound absorption function, which helps to improve the indoor acoustic environment. The thickness of the insulation layer 3 is 5mm to 10mm. Such a thickness can provide sufficient thermal insulation effect without making the entire panel too bulky.
[0021] The grid panel 11 is connected by crisscrossing slats, which divide the area where the grid panel 11 is located into several spaces. Adjacent spaces are connected through through holes 111 opened on the slats. During processing, the material of the fireproof layer 2 is injected into the area where the grid panel 11 is located, and the material of the fireproof layer 2 is solidified in the grid panel 11 to form a fireproof layer 2.
[0022] The fireproof layer 2 is made of a mixture of flame retardant and foaming agent. The main function of the flame retardant is to slow down the burning speed of the material when a fire occurs and prevent the fire from spreading rapidly. The function of the foaming agent is to generate gas at high temperature to expand the material to form a foam structure. This foam structure can not only block the flame, but also have a heat insulation effect, further improving the overall fireproof performance of the wall panel. The flame retardant and foaming agent mixture is filled between the grid panels 11, and the two sides are respectively connected to the insulation layer 3. After curing, the flame retardant and foaming agent mixture is tightly connected to the insulation layer 3, and the entire panel structure is firm. At the same time, the flame retardant and foaming agent mixture passes through the through hole 111 to form an overall fireproof layer 2 structure between the grid panels 11. The fireproof layer 2 is socketed with the grid panels 11, and the grid panels 11 form a supporting grid between the fireproof layer 2 to enhance the structural strength of the fireproof layer 2.
[0023] Working process: Use high-strength lightweight composite materials as the panel body 1, prepare the insulation layer 3 according to the internal size of the panel body 1, and coat the surface of the insulation layer 3 with a waterproof breathable membrane 31, place the insulation layer 3 together with the waterproof breathable membrane 31 on both sides of the grid plate 11, open an injection port on one side of the grid plate 11, and inject a mixture of flame retardant and foaming agent into the grid plate 11 to ensure that each part is fully filled. After the flame retardant and foaming agent mixture is cured, a fireproof layer 2 is formed. A layer of nano-scale fireproof coating is coated on the outside of the panel body 1. When working, the panel body 1 provides strength support. When there is no fire, the insulation layer 3 has a certain sound absorption function, which helps to improve the indoor acoustic environment. The waterproof breathable membrane 31 ensures the stability and service life of the panel in a humid environment. When a fire occurs, the insulation layer 3 provides sufficient insulation effect, and the fireproof layer 2 can expand to form a protective barrier to prevent further spread of flames and heat.
