Description

Technical Field

[0001] The utility model relates to the technical field of extruded boards, in particular to a moisture-proof and flame-retardant extruded board. Background Art

[0002] The full name of extruded polystyrene board is extruded polystyrene foam board, abbreviated as extruded board, also known as XPS board, extruded polystyrene board, extruded board is a rigid foam plastic board with continuous closed-cell foaming, which is made of polystyrene resin supplemented with polymers, injected with catalysts while heating and mixing, and then extruded and pressed out. The interior is an independent closed bubble structure. It is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), and low thermal conductivity; however, since the extruded board will shrink and deform when it comes into contact with open flames, if a fire occurs, it will cause the open flame to directly burn through the extruded board, resulting in low safety of the extruded board. For this reason, we propose a moisture-proof and flame-retardant extruded board. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a moisture-proof and flame-retardant extruded board.

[0004] The technical solution adopted by the utility model to solve the technical problem is a moisture-proof and flame-retardant extruded board, comprising an extruded board body, a glass fiber mesh layer is sewn and installed on the outer periphery of the extruded board body, and a sound-absorbing cotton layer is sewn and installed on one side of the glass fiber mesh layer away from the extruded board body;

[0005] A diamond mesh layer is sewn and installed on one side of the sound-absorbing cotton layer away from the glass fiber mesh layer, and a rock wool layer is bonded to the outer peripheral surface of the diamond mesh layer.

[0006] By adopting the above technical solution, when the extruded board is used, the diamond mesh layer on the outer surface of the extruded board is convenient for supporting and improving the strength, and the rock wool layer on the outer surface of the diamond mesh is convenient for directly blocking the open flame, so that when a fire occurs, the main body of the extruded board is directly separated from the open flame and flame-retarded, thereby improving the flame retardant performance and safety of the extruded board;

[0007] The glass fiber mesh layer set up on the periphery of the extruded board body can cooperate with the diamond mesh layer, so that the sound-absorbing cotton layer can be more stably bonded to the periphery of the extruded board body. At the same time, the sound-absorbing cotton layer is convenient for improving the noise reduction and sound insulation performance of the extruded board body, and for improving the diversification of the extruded board functions and making the extruded board operate more stably.

[0008] Specifically, the side of the rock wool layer away from the diamond mesh and the side of the extruded board body away from the glass fiber mesh layer are both bonded with an aluminum foil wool layer.

[0009] By adopting the above technical solution, the aluminum foil cotton layer has certain elasticity, heat preservation, moisture-proof and fire-proof properties, so that the moisture-proof and flame-retardant properties of the extruded board are improved during use.

[0010] Specifically, the outer peripheral surface of the aluminum foil cotton layer is coated with a waterproof layer.

[0011] By adopting the above technical solution and the design of the waterproof layer, it is convenient to further improve the moisture-proof performance of the extruded board body.

[0012] Specifically, the diamond mesh layer is made of flexible material.

[0013] By adopting the above technical solution, the diamond mesh layer made of flexible metal material can conveniently improve the strength of the extruded board body and reduce the deformation and damage of the extruded board body due to pressure during use.

[0014] Specifically, the glass fiber mesh layer, the sound-absorbing cotton layer, the diamond mesh layer, the rock wool layer, the aluminum foil cotton layer and the waterproof layer are sequentially distributed on the outer peripheral surface of the extruded board body.

[0015] By adopting the above technical scheme, the glass fiber mesh layer, sound-absorbing cotton layer, diamond mesh layer, rock wool layer, aluminum foil cotton layer and waterproof layer distributed in sequence on the periphery of the extruded board body can be used in conjunction with each other, so that the moisture-proof and flame-retardant properties of the extruded board body are effectively improved, so that the extruded board body can be used more stably.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of diamond mesh layer and rock wool layer. When the extruded board is used, the diamond mesh layer on the outer surface of the extruded board is convenient for supporting and improving the strength, while the rock wool layer on the outer surface of the diamond mesh is convenient for directly blocking the open flame. In the event of a fire, the main body of the extruded board is directly separated from the open flame and flame-retarded, thereby improving the flame retardant performance and safety of the extruded board.

[0018] 2. The technical solution of the present application adopts the design of a glass fiber mesh layer and a sound-absorbing cotton layer. The glass fiber mesh layer established on the periphery of the extruded board body can cooperate with the diamond mesh layer, so that the sound-absorbing cotton layer can be more stably bonded to the periphery of the extruded board body. At the same time, the sound-absorbing cotton layer is convenient for improving the noise reduction and sound insulation performance of the extruded board body, and is convenient for improving the diversification of the functions of the extruded board, and making the extruded board operate more stably.
