Abstract

The invention relates to a fireproof, sound-insulating, energy-saving and anti-cracking composite externally-pasted wallboard and a wall body. The composite externally-pasted wallboard comprises a heat preservation layer, a heat preservation protection layer and a construction mortar layer which are sequentially arranged in a layered mode. Wherein the thermal insulation layer comprises one of an organic thermal insulation material, an inorganic thermal insulation material or an organic / inorganic composite material; the thermal insulation protective layer comprises the following raw materials: inorganic gelling slurry, light particles and an additive a; and the construction mortar layer comprises the following raw materials: inorganic gelling slurry, fine aggregate and an additive b. The composite externally-pasted wallboard comprises the heat preservation layer, the heat preservation protection layer and the construction mortar layer which are sequentially arranged in a layered mode, arrangement among different layers is scientific and reasonable, and the requirements for fire prevention, sound insulation, energy saving and cracking resistance can be completely met.

Description

technical field [0001] The invention belongs to the field of composite boards, and in particular relates to a fire-proof, sound-insulating, energy-saving and anti-cracking composite exterior wall board and wall body. Background technique [0002] With the continuous improvement of the country's high requirements for green, low-carbon, and energy-saving construction industries, the construction of new houses and the energy-saving renovation of old houses have become important ways to achieve them. At present, the quality problems of cracking, falling off, hollowing and leakage of external wall insulation of domestic buildings are common, and even cause major safety accidents such as fire, which seriously threaten people's life safety and property safety. Therefore, a new type of thermal insulation structure is urgently needed. , which not only ensures safety, but also prolongs the service life, reaching the same life as the same building. Therefore based on this, propose tec...
