Flame Retardant Thermal Insulation Plastic Board

Wood-plastic composite board is a kind of wood-based material mainly composed of thermoplastic polymer materials and processing aids.It is a high-tech, green and environmentally friendly new decorative material that is mixed evenly and then heated and extruded by mold equipment. It has the performance and characteristics of wood and plastic and is a new composite material that can replace wood and plastic.

During use, the traditional plastic board has a simple structure and cannot effectively reduce the heat exchange efficiency on both sides of the plastic board, resulting in poor thermal insulation effect.Moreover, traditional plastic wood boards are prone to burning when exposed to high temperatures or open flames, and have poor flame retardant effects.In view of the problems existing in the prior art, the purpose of this utility model is to provide a new type of flame-retardant and heat-insulating plastic wood board.The foamed cement layer, insulation cavity and airgel felt layer can separate the plastic board from the outside air, reduce the heat exchange efficiency on both sides of the plastic board, and improve the insulation effect.The first flame-retardant layer and the second flame-retardant layer can perform multiple flame retardants on the plastic board to prevent the plastic board from burning due to high temperature or open flame and improve the flame retardant effect.

In order to solve the above problems, there is a technical solution adopted by the utility model (CN 211775303 U).New flame-retardant and insulated plastic wood boards, including base plates, with a foamed cement layer fixedly installed on the surface of the base plates, with a thickness of 2-4mm.There are thermal insulation cavities on both sides of the foamed cement layer, and airgel felt layers are fixedly connected to the outside on both sides of the foamed cement layer with a thickness of 1-2mm.A first flame retardant layer with a thickness of 1-2mm is fixedly installed on the outer side of the airgel felt layer, and a second flame retardant layer is fixedly installed with a thickness of 1-2mm on the outer surface of the first flame retardant layer.The foamed cement layer, insulation cavity and airgel felt layer can separate the plastic board from the outside air.Reduce the heat exchange efficiency on both sides of the plastic board and improve the insulation effect. The first flame retardant layer and the second flame retardant layer can perform multiple flame retardants on the plastic board to prevent the plastic board from burning due to high temperature or open flame and improve the flame retardant effect. .The second flame retardant layer is fixedly installed on the outer surface of the first flame retardant layer, with a thickness of 1-2mm.The second flame-retardant layer is made of Portland cement material, which can further improve the flame-retardant effect of the plastic board and improve the use effect.Compared with the existing technology, the advantage of the new plastic board is that the foamed cement layer, insulation cavity and airgel felt layer can separate the plastic board from the outside air, reduce the heat exchange efficiency on both sides of the plastic board, and improve the insulation effect. , through the first flame retardant layer and the second flame retardant layer, the plastic board can be multi-flame retardant to prevent the plastic board from burning due to high temperature or open flame, and improve the flame retardant effect.
