Exterior wall cladding and technique for producing the same

Abstract

The invention relates to a board and a production technology thereof, in particular to an exterior wall cladding and a production technology thereof. The exterior wall cladding sequentially comprises an extruded sheet layer, a bo-mei board layer and a metallic paint layer from bottom to top. The production technology comprises the following steps: the surface of the bo-mei board is added with a layer of mixture formed by magnesium oxide and putty powder, and the mixture is trowelled; the surface layer of the processed bo-mei board is polished to lead the surface to be level; the surface layer of the polished bo-mei board is coated with a layer of fluorocarbon metal paint; an XPS extruded sheet with the same size as the bo-mei board is processed; the underside of the processed bo-mei board is agglutinated with the processed XPS extruded sheet by epoxide resin. The exterior wall cladding has good heat preservation and insulation performance, is energy-saving and environment-friendly, has level and beautiful surface, and is convenient for construction.

Description

technical field [0001] The invention relates to a board and its production process, in particular to an exterior wall hanging board and its production process. Background technique [0002] Most of the exterior walls of modern buildings are decorated with decorative bricks, but with the development of the construction industry, more and more buildings use exterior wall panels to replace decorative bricks, especially some high-rise buildings. Existing exterior wall hanging boards generally include aluminum alloy exterior wall hanging boards, plastic hanging boards, cement calcium silicate boards, cement fiberboards, and the like. Among them, the aluminum alloy exterior wall hanging panels are currently used more, but the price of the aluminum alloy exterior wall hanging panels is relatively high, and the thermal insulation performance is not good.

AI Technical Summary

Problems solved by technology

Among them, aluminum alloy exterior wall hanging panels are currently used more, but the price of aluminum alloy exterior wall hanging panels is relatively high, and the thermal insulation performance is not good.

Plastic hanging boards are not fireproof, easy to deform, take a long time and are also easy to age, have a short service life, and have poor thermal insulation performance

Although calcium silicate board and cement fiber board are not easy to deform and can also be fireproof, they are heavy and easy to break, and the processing technology is complicated, and the surface smoothness is difficult to handle

It can be seen that the existing exterior wall sidings have their own shortcomings, cannot meet the requirements of modern building exterior walls, and need to be improved.
