Abstract

The invention belongs to the technical field of building material, and discloses a lightweight external thermal-insulation decorative external wall panel used for prefabricated buildings, and a preparation method thereof. The lightweight external thermal-insulation decorative external wall panel used for prefabricated buildings comprises, from outside in, an external wall decorative layer, an external wall panel, a sprayed polyurethane heat-insulation layer, a lightweight grouting material layer, an internal wall panel, and an internal wall decorative layer; and the external wall panel, the sprayed polyurethane heat-insulation layer, the lightweight grouting material layer, and the internal wall panel are penetrated by a steel frame. According to the preparation method, the wall body framework is prepared from U-shaped steel processed from galvanized steel sheet with a thickness of 0.8 to 3.0mm, the strength is higher than that of light gauge steel, the weight is ligher than that of reinforced concrete, wallboard per square meter weight is lower than 150kg, wall body is provided with pre-embedded matching add-on parts; based on building integral body design requirements, external hanging or inlaying can be adopted, the applicability is high, and installation is rapid and convenient.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a light-weight exterior thermal insulation decorative exterior wall panel for a prefabricated building and a preparation method thereof. Background technique [0002] Part or all of the components of the building are prefabricated in the factory, then transported to the construction site, and the building is assembled by reliable connection, which is called a prefabricated building. The advantage of this construction method is that the construction speed is fast, the construction is less restricted by climatic conditions, labor is saved and the construction quality can be improved. The prefabricated non-load-bearing wall panel is an indispensable prefabricated component, but the quality of ordinary prefabricated reinforced concrete wall panels is too high. Large, inconvenient for transportation and hoisting, and the safety factor of towing is large, so th...
