Description

Composite wallboard with extruded polystyrene board sandwich layer

technical field

The utility model belongs to the technical field of composite wall panels, in particular to a composite wall panel provided with a sandwich layer of extruded polystyrene boards.

Background technique

If the industrialization of construction is a revolution in the construction industry, then prefabricated construction is the inevitable development direction of construction methods. In February 2016, the "Several Opinions of the Central Committee of the Communist Party of China and the State Council on Further Strengthening the Management of Urban Planning and Construction" were issued, proposing to increase policy support, vigorously promote prefabricated buildings, and strive to make prefabricated buildings account for new buildings in about 10 years. The proportion reached 30%. As an important part of prefabricated buildings, lightweight slats have many advantages such as factory production, integrated production and processing, prefabricated construction and installation, and are ideal wall materials for prefabricated buildings.

At present, the lightweight slats widely used in the market mainly include: foam concrete slats, gypsum fiber reinforced slats, glass fiber reinforced cement (GRC) lightweight porous slats, polystyrene particle composite sandwich lightweight slats, cement hair Foam composite sandwich lightweight slats, etc. Although the above lightweight slats have mature technology and have entered the market for a long time, there are many problems in the product itself that are difficult to solve. (1) Hollow wall panels represented by foam concrete slabs and cement mortar slats, in order to reduce the cavity in the center of self-weight, affect the overall strength of the panel, and are prone to deformation and cracking. At the same time, the center of the panel is not filled with thermal insulation materials. The thermal insulation and sound insulation performance is not ideal; (2) Sandwich lightweight slats represented by polystyrene particle sandwich slats. Mortar or finished magnesite boards or calcium silicate boards are bonded into an integrated structure through adhesives. Compared with hollow slats, this kind of light-weight slats have better thermal insulation performance, but the product manufacturing process is more complicated. The bulk density is high, the installation and construction are inconvenient, and the production, construction and installation costs remain high.
