Thermal insulation function of wood plastic composite material
Wood plastic composite thermal insulation wallboard is made of polyethylene, polypropylene, polyvinyl chloride and their copolymers and other thermoplastic plastics and wood powder, plant straw powder, plant seed shells and other wood powder materials as materials, through extrusion and injection molding methods , pressing method to make hollow board, filled with various insulation materials to form a composite board. A new type of wall decoration material that integrates decoration, heat preservation, sound insulation, and fire protection. Its heat preservation effect is 7 degrees higher than ordinary boards and 10 degrees higher than paint, which can reduce the loss of indoor temperature, thus in the cold winter create a warm home environment.
Wood plastic composite wallboard is currently the mainstream thermal insulation material in the world. It is mostly used for wall, door and window, exterior wall and other architectural decoration, which shows its thermal insulation performance. Through the application of environmentally friendly thermal insulation materials in the product, wood plastic composite wall panels can not only have the thermal insulation effect in winter, but also have the thermal insulation effect in summer, and the sound insulation effect can reach 29 decibels.
The outer layer of the wood plastic composite panel is enclosed to form a closed wood plastic composite wallboard cavity, and various thermal insulation materials are added in the middle to make self-insulating wood plastic composite panels. This wood plastic composite panel can be applied to the outer wall of steel structures to achieve the thermal insulation performance of the steel structure itself. It also reduces the weight of the building itself and saves materials. Many types of exterior wall systems can now be used in steel structures. Wood plastic composite self-insulation is used in steel structures, which not only plays the role of exterior walls, but also no longer requires a separate insulation layer. However, since wood plastic composite self-insulation board is a new exterior wall panel, and steel-frame wood plastic composite exterior wall self-insulation system is a new exterior wall system, there has been no actual research and application before, and a lot of work still needs to be carried out. Such as optimizing the formula of wood plastic composite materials and strengthening the production process to reduce production costs and improve its durability; optimizing the structure of the board and improving its thermal insulation.
