Description

Technical Field

[0001] The utility model relates to the technical field of building boards, in particular to an environmentally friendly flame-retardant building board. Background Art

[0002] Wood boards are easy to cut and are widely used in the construction field. For example, formwork, decorative panels and partitions can all be made of wood boards.

[0003] The flame retardancy of existing wood boards is generally poor, and there are certain safety hazards when used in the construction field. Although flame retardant coatings can be used to improve the surface flame retardant effect of wood boards, the flame retardant coatings affect the environmental friendliness of the wood boards, and the thickness of the flame retardant coatings is generally relatively thin, and the flame retardant effect is very limited, which needs to be improved.

[0007] Wherein, the core board is made of original wood board or artificial board.

[0008] Wherein, a first flame retardant coating is arranged on the front side of the core board, and a second flame retardant coating is arranged on the back side of the core board.

[0009] Wherein, the inner walls of the first groove and the second groove are respectively provided with flame retardant glue.

[0010] Wherein, the first flame retardant cloth cover and the second flame retardant cloth cover are both made of glass fiber cloth cover or polyester flame retardant fiber cloth cover.

[0011] Wherein, the first groove and the second groove are staggered in vertical distribution.

[0012] Wherein, the first environmental protection fireproof layer and the second environmental protection fireproof layer each use a layer of diatom mud.

[0013] The beneficial effects of the utility model are as follows: an environmentally friendly flame-retardant building board material, which provides double-sided protection for the core board by means of a first environmentally friendly fireproof layer and a second environmentally friendly fireproof layer, can both prevent fire and enhance the environmental protection effect, and even if the first environmentally friendly fireproof layer and the second environmentally friendly fireproof layer are damaged, a second flame retardant effect can be provided by means of the flame retardants in the exposed first flame-retardant cloth cover and the second flame-retardant cloth cover, thereby greatly enhancing the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model;

[0015] Figure 2 yes Figure 1 A partial enlarged view of part A. DETAILED DESCRIPTION

[0016] Combine the following Figure 1-2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 and Figure 2 The environmentally friendly flame-retardant building board shown includes: a core board 1, a first flame-retardant cloth cover 11, a second flame-retardant cloth cover 10, a first environmentally friendly fireproof layer 2 and a second environmentally friendly fireproof layer 5. The core board 1 is made of original wood board or artificial board, and the material source is wide.

[0018] The core board 1 is arranged between the first environmentally friendly fireproof layer 2 and the second environmentally friendly fireproof layer 5. The first environmentally friendly fireproof layer 2 and the second environmentally friendly fireproof layer 5 provide double-sided protection for the core board 1, which can prevent fire and improve environmental protection effect.

[0019] In this embodiment, the first environmentally friendly fireproof layer 2 and the second environmentally friendly fireproof layer 5 respectively adopt a layer of diatom mud. Diatom mud has a porous structure, low thermal conductivity, certain thermal insulation effects and physical adsorption properties, good environmental protection, and can withstand high temperatures of 1700°C without burning, and has good fire retardant effects.

[0020] First grooves 7 extending along the length direction are arranged at upper and lower intervals on the front side of the core board 1, and the first flame-retardant cloth cover 11 is arranged in the first groove 7. Second grooves 9 extending along the length direction are arranged at upper and lower intervals on the back side of the core board 1. In the present embodiment, the first grooves 7 and the second grooves 9 are staggered in the upper and lower positions to reduce the adverse effects on the structural strength of the core board 1.

[0021] The second flame retardant cloth sleeve 10 is arranged in the second groove 9. In this embodiment, the inner walls of the first groove 7 and the second groove 9 are respectively provided with flame retardant glue 8 to fix the first flame retardant cloth sleeve 11 and the second flame retardant cloth sleeve 10, and the structure is stable.

[0022] like Figure 2 As shown, the first flame retardant cloth cover 11 and the second flame retardant cloth cover 10 are respectively filled with flame retardant 6. The first flame retardant cloth cover 11 and the second flame retardant cloth cover 10 can be made of glass fiber cloth cover or polyester flame retardant fiber cloth cover at the same time, which has good flame retardant effect and can be broken under the action of open flame to expose the flame retardant 6. The flame retardant 6 can be made of environmentally friendly halogen-free flame retardant. During use, when the first environmentally friendly fireproof layer 2 and the second environmentally friendly fireproof layer 5 are damaged, the second flame retardant will be performed through the flame retardant in the exposed first flame retardant cloth cover 11 and the second flame retardant cloth cover 10, which greatly improves the safety of use.

[0023] In this embodiment, a first flame retardant coating 3 is provided on the front side of the core board 1, and a second flame retardant coating 4 is provided on the back side of the core board 1. The first flame retardant coating 3 and the second flame retardant coating 4 are used to achieve final protection of the surface of the core board 1, and perform the third flame retardancy. Moreover, the first flame retardant coating 3 and the second flame retardant coating 4 are usually covered by the first environmentally friendly fireproof layer 2 and the second environmentally friendly fireproof layer 5, which are more environmentally friendly and have good durability.

[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
