Lightweight heat-preservation paper-gypsum integral wall material

Abstract

The invention belongs to the field of building construction, and provides a lightweight heat-preservation paper-gypsum integral wall material which comprises one lightweight paper gypsum board with the thickness of 40 mm (1), one polyurethane adhesive (2), foam concrete with the thickness of 100 mm (3), a 400X400 steel wire mesh (4), the other polyurethane adhesive (2) and the other lightweight paper gypsum board with the thickness of 40 mm (1) in sequence from inside to outside, wherein the strength grade of the foam concrete with the thickness of 100 mm (3) is higher than or equal to C20; and the 400X400 steel wire mesh is embedded in the foam concrete with the thickness of 100 mm (3). The manufactured lightweight heat-preservation paper-gypsum integral wall material has the beneficial effects that the dead weight is light, and the heat-preservation and thermal insulation effects are good; as a combination of hardness and softness, the lightweight heat-preservation paper-gypsum integral wall material is not easy to crack, and the appearance effect is good; and by the adoption of such a sandwich structure, the anti-cracking capability, the anti-permeability performance and the anti-freezing performance of the wall are excellent.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a light-weight thermal insulation paper-faced gypsum integral wall material. Background technique [0002] The wall is the main interface between the interior of the house and the external environment. The thermal insulation and waterproof performance of the wall affect the living comfort of the occupants in the house. At present, the prefabricated building wall materials that are vigorously promoted mostly use prefabricated large slab materials made of concrete raw materials, which have relatively high thermal conductivity and general thermal insulation performance, which is not conducive to energy saving and environmental protection of buildings. Contents of the invention [0003] The purpose of the present invention is to improve the thermal insulation performance of the assembled wall, and propose a light-weight thermal insulation paper-faced gypsum integral ...
