Flame retardant and thermal insulation technology scheme for plastic wood composite materials

Plastic wood composite board is a high-tech, green, and environmentally friendly new decorative material mainly made of wood as the basic material, thermoplastic polymer materials, and processing aids, mixed evenly and then extruded by mold equipment. It combines the properties and characteristics of wood and plastic, and is a new type of composite material that can replace wood and plastic.
Traditional plastic boards have a simple structure during use, which cannot effectively reduce the heat exchange efficiency on both sides of the board. The insulation effect is poor, and traditional plastic boards are prone to combustion and have poor flame retardancy when exposed to high temperatures or open flames. In view of the problems existing in the prior art, the purpose of the utility model is to provide a new type of flame retardant and thermal insulation plastic board. The plastic board can be separated from the outside air through the foaming cement layer, the thermal insulation chamber and the aerogel felt layer, reducing the heat exchange efficiency on both sides of the plastic board, improving the thermal insulation effect. The plastic board can be multi flame retardant through the first flame retardant layer and the second flame retardant layer, so as to prevent the plastic board from burning under high temperature or open fire, Improve flame retardancy.
