Plastic Wood Exterior Wall Panels Have Good Thermal Insulation Effect

Wood-plastic exterior wall panels are new materials made of wood or other biomass fiber materials and thermoplastics, that is, thermoplastic composite materials filled with wood fibers or other biomass fibers reinforced and modified. It is an exterior wall panel profile with a hollow rate of about 80% that is formed by high-temperature and high-pressure processes using wood powder, plastic, stone powder, and various processing aids, and is filled with materials with excellent thermal insulation properties to form a high-efficiency energy-saving self-insulation wall. plate.

At present, the types of domestic building exterior wall panels are mainly composites of inorganic panels and thermal insulation panels. The connection area between the two panels of this composite panel is large, and the thermal bridge effect is significant, which affects the overall thermal insulation effect of the composite wall panel. The research and development of composite wall panels with high mechanical strength, small thermal bridge effect, and good comprehensive thermal insulation effect is the long-term pursuit goal of building wall panels.

The use of high-performance plastic-wood composite materials to make thermal insulation wall structures (as the skeleton of the board) can reduce the wall thickness of structural materials from about 25mm to about 6mm, thereby significantly improving the filling rate of thermal insulation materials and improving the thermal insulation effect. significantly. This kind of self-insulating plastic-wood exterior wall panel with high mechanical strength and good thermal insulation performance has a huge market demand and broad application prospects.

The self-supporting self-insulation prefabricated building exterior wall system uses the convex edges and grooves of the exterior wall panels to insert the exterior wall panels along the outer sides of the original building beams and columns to form an exterior wall, and through the "L"-shaped connectors, One-way connectors, nested modules and I-shaped two-way connectors are spliced and assembled to form an overall exterior wall. The bottom and top ends of the overall exterior wall are embedded in the frame composed of channel steel or angle steel and are respectively connected to the foundation through the frame. connected to the roof, where:

1. The two vertical end faces of the "L"-shaped connector and the exterior wall panels are respectively provided with convex ribs and grooves, which are placed at the corners of the wall during the application, and are respectively plugged with the exterior wall panels on both sides;

2. A groove is provided at the mating end of the one-way connector and the exterior wall panel, and it is placed at the window and door side when applied;

3. The mating end of the nesting module and the exterior wall panel is provided with a groove, which is placed at the joint between the entire panel and the partial panel of the exterior wall panel, embedded in the cavity on the cutting side of the partial panel, and fixed in the cavity on the inner wall of the cavity;

4. I-shaped two-way connectors are used in two-story and multi-story buildings to connect the outer wall panels of the upper and lower floors.

Self-insulating plastic-wood exterior wall panels have high mechanical strength, good thermal insulation performance, small specific gravity, can be sawed, planed, nailed, water-resistant, insect-resistant, water absorption rate and dimensional change rate are small, convenient construction, and can avoid wall cracking Features.

1. The wood-plastic self-insulation exterior wall system uses the convex edges and grooves of the exterior wall panels to insert the exterior wall panels along the outside of the original building beams and columns to form a self-supporting self-insulation assembly exterior wall system, thus eliminating Influenced by cold and heat bridges, the heat preservation effect is good.

2. The basic components are composed of wall panels, "L"-shaped panels, one-way connectors, nested modules, and I-shaped two-way connectors. The components are spliced with each other to form an assembled overall exterior wall with controllable dimensions, which is convenient for construction.

3. Plastic-wood self-insulating exterior wall panels are light in weight, environmentally friendly, high in strength, good in durability, excellent in thermal insulation performance, and can be recycled many times, meeting the requirements of the national building energy conservation and building a resource-saving and environment-friendly society.
