[0003] At present, most foam panels are fixed together using hinges or metal sheets with screws. There is a lack of a clamping structure for the foam panels, which is not only inconvenient for construction and installation, but also easy to damage when using screws with metal sheets at the installation location due to the small force bearing area. There is a risk of slipping, which leads to instability of the foam panels after splicing.

[0004] An existing patent (publication number: CN218177631U) discloses a foam board with a clip-on structure. By setting a clip-on structure for connecting the two foam boards between the two foam boards, the clip-on structure can be directly inserted between the two foam boards for connection during use. The operation is simple and convenient. Moreover, the clip-on structure can increase the contact area with the foam board after insertion under the action of its own spring, thereby improving the firmness of the connection. The operation is simple and convenient.

[0005] In response to the above problems, existing patents have provided solutions, but due to the material limitations of the foam board, it is often easy to burn when encountering a high temperature environment, and the fire spreads rapidly, which not only causes property damage, but may also endanger personal safety.

[0006] Therefore, a foam board with a high-temperature flame-retardant structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-5 , this utility model provides a technical solution:

[0027] A foam board with a high-temperature flame-retardant structure includes two foam board main bodies 1. Bumps 2 are provided on both sides of the foam board main body 1, and the two relative bumps 2 are in contact with each other. A groove is formed between the top and bottom of the two relative bumps 2, and a flame-retardant connecting plate 3 is provided inside the groove. A fixing column 4 is passed through the inside of the top flame-retardant connecting plate 3, and the bottom of the fixing column 4 passes through the bump 2 and is connected to the bottom flame-retardant connecting plate 3. Rubber clamps 5 are sleeved on the top and bottom of the surface of the fixing column 4.

[0028] In this embodiment: by setting the insulating layer 14, the insulating layer 14 can form a solid flame retardant defense line between the upper main body layer 11 and the lower main body layer 12. When the foam board main body 1 is locally affected by high temperature, the insulating layer 14 can prevent the flame from spreading inside the foam board main body 1. By setting the protective layer 15, the external flame retardant performance of the foam board main body 1 can be enhanced. When facing a high temperature environment, it has an excellent flame retardant effect and can effectively delay or even prevent the occurrence and spread of combustion.

[0029] Specifically, such as Figure 3As shown, the protective layer 15 includes an external flame retardant layer 151, which is arranged on one side close to the upper main body layer 11 and the lower main body layer 12, and a high temperature resistant layer 152 is arranged on the other side of the external flame retardant layer 151, and a wear-resistant layer 153 is arranged on the side of the high temperature resistant layer 152 away from the external flame retardant layer 151.

[0030] In this embodiment: by setting up the protective layer 15, under the action of the external flame retardant layer 151, the occurrence of external combustion can be suppressed, and under the setting of the high-temperature resistant layer 152, the foam board body 1 can withstand higher temperatures, making it less likely to burn, and through the wear-resistant layer 153, the high-temperature resistant layer 152 can be protected, making it less likely to be damaged by friction, thereby ensuring the effectiveness of the high-temperature resistant layer 152.

[0031] Specifically, such as Figure 2 As shown, the connecting layer 13 is made of organic silicone adhesive, and the insulating layer 14 is tightly connected to the upper main body layer 11 and the lower main body layer 12 respectively through the organic silicone adhesive.

[0032] Specifically, such as Figure 2 As shown, the insulating layer 14 is composed of an aramid flame-retardant fiber mesh layer and is bonded between opposite sides of the upper main body layer 11 and the lower main body layer 12 .

[0033] In this embodiment: by providing a connecting layer 13 composed of organic silicone adhesive, the connection strength between the insulating layer 14 and the upper main layer 11 and the lower main layer 12 can be ensured, and by providing an insulating layer 14 composed of an aramid flame-retardant fiber mesh layer, a stable flame-retardant defense line can be formed inside the foam board body 1 to prevent the spread of flames inside.

[0034] Specifically, such as Figure 3 As shown, the outer flame retardant layer 151 is made of a halogen-free flame retardant and is evenly coated on one side close to the upper main body layer 11 and the lower main body layer 12 .

[0035] Specifically, such as Figure 3 As shown, the high temperature resistant layer 152 is made of an organic silicon coating and is evenly coated on a side close to the outer flame retardant layer 151 .

[0036] Specifically, such as Figure 3 As shown, the wear-resistant layer 153 is made of a polytetrafluoroethylene coating and is evenly coated on a side close to the high-temperature resistant layer 152 .

[0037] In this embodiment: by providing an external flame retardant layer 151 composed of a halogen-free flame retardant, non-combustible gas can be rapidly generated at high temperatures to form an isolation layer, effectively preventing oxygen from contacting the foam board body 1, and suppressing the occurrence of combustion from the outside; and by providing a high-temperature resistant layer 152 composed of a silicone coating, the foam board body 1 can be made to withstand higher temperatures, making it less likely to burn; and by providing a wear-resistant layer 153 composed of a polytetrafluoroethylene coating, a smooth and wear-resistant film can be formed on the surface of the high-temperature resistant layer 152, effectively reducing the friction and wear between the high-temperature resistant layer 152 and other objects, thereby protecting the high-temperature resistant layer 152 and preventing it from being damaged.

[0038] Specifically, such as Figure 4 、 Figure 5 As shown, the protrusion 2 is integrally formed with the foam board body 1, an elastic sheet 6 is provided inside the rubber clamp 5, and the surface of the rubber clamp 5 is in close contact with the inner wall of the flame retardant connecting plate 3, and the interior of the flame retardant connecting plate 3 and the protrusion 2 are provided with through holes for use with the fixing column 4.

[0039] In this embodiment: the flame retardant connecting plate 3 is placed in the groove formed between the top and bottom of the two relative protrusions 2, and the fixing column 4 passes through the flame retardant connecting plate 3 and the protrusion 2, and then the elasticity of the elastic sheet 6 is used to make the surface of the rubber clamp 5 closely contact with the inner wall of the flame retardant connecting plate 3, so as to realize the connection between the flame retardant connecting plate 3 and the protrusion 2, and then realize the splicing work between the two foam board main bodies 1, and ensure the connection strength.

[0040] Working principle: When the foam board main body 1 is in use, the flame-retardant connecting plate 3 can be placed in the groove formed between the top and bottom of the two relative protrusions 2, and the flame-retardant connecting plate 3 and the protrusion 2 can be penetrated by the fixing column 4, and then the elasticity of the elastic sheet 6 can be used to make the surface of the rubber clamp 5 closely contact the inner wall of the flame-retardant connecting plate 3, so as to realize the connection between the flame-retardant connecting plate 3 and the protrusion 2, and then realize the splicing work between the two foam board main bodies 1. When the foam board main body 1 faces high temperature, the insulating layer 14 can be used to form a solid flame-retardant defense line between the upper main body layer 11 and the lower main body layer 12. The insulating layer 14 can prevent the flame from spreading inside the foam board main body 1, and the protective layer 15 can form a flame-retardant defense line on the outside of the foam board main body 1. At high temperature, non-combustible gas can be quickly generated to form an isolation layer, which effectively prevents oxygen from contacting the foam board main body 1 and suppresses the occurrence of combustion from the outside.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
