Abstract

The invention provides a novel composite insulating thin-wall external wall board. The novel composite insulating thin-wall external wall board mainly comprises the components of fiber-woven-mesh reinforced concrete and an insulating-wall-body material, wherein the fiber-woven-mesh reinforced concrete consists of the components of high-performance fine concrete and a fiber woven mesh; the fiber woven mesh is used as a reinforced material; the insulating-wall-body material comprises one or all of a cement-based material insulating board and insulating material powder. The invention also provides a preparation method of the novel composite insulating thin-wall external wall board. The external wall board provided by the invention integrates the advantages of being long in service life, having a light-weight thin wall, capacity of heat insulation, sound insulation, vibration resistance, impact resistance, fire resistance, and water resistance, being simple in installation and surface decoration processes and the like, is applicable to outer-wall insulation of buildings and is a novel composite insulating building outer-wall structure with a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to an exterior wall structure, in particular to an exterior wall panel made of fiber braided mesh reinforced concrete compounded with a new heat preservation material. Background technique [0002] The enclosure structure is an important part of the building, and the exterior wall occupies a considerable proportion in the enclosure structure. The quality of the materials used in the exterior wall structure directly affects the actual effect of building energy conservation. The commonly used external wall insulation materials in my country are mainly divided into organic (such as expanded polystyrene (EPS)), inorganic (such as expanded perlite) and composite materials. Organic thermal insulation materials were widely used at one time, but they were gradually eliminated due to their disadvantages such as aging resistance and flammability. Inorganic materials have a large cap...
