Multifunctional energy-saving composite board with multi-layer cavity structure

Abstract

The invention relates to a multifunctional energy-saving composite plate with a multi-layer cavity structure. The multifunctional energy-saving composite plate is arranged on the outer side of a wall body base body and is used for external heat preservation of an exterior wall. The multifunctional energy-saving composite plate with the multi-layer cavity structure comprises a protection layer, an air layer, a filling layer, a partition plate, a heat preservation layer, a partition plate and a decoration layer from inside to outside. The partition plates are arranged on two sides of the heat preservation layer and have good leakproofness and a heat reflection function and play a good heat-insulation role, material diffusion of the heat preservation layer can be further prevented, and the service life is prolonged. The air layer is formed by the gap between the protection layer and the filling layer and has fireproof and heat-insulation performance.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a multifunctional energy-saving composite board with a multi-layer cavity structure, which is arranged on the outer side of the wall body and used for external heat preservation of the outer wall. Background technique [0002] With the rapid development of my country's economy, the continuous expansion of housing construction scale, the acceleration of urbanization and the improvement of people's living standards, buildings gradually occupy a considerable part of my country's energy consumption. In order to solve the problem of high energy consumption of buildings, the state implements an important policy of building energy conservation, which effectively reduces the energy consumption of buildings on the premise of meeting the requirements of building construction. Traditional building energy-saving structures are divided into two types: internal insulati...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing external wall insulation structure consists of a single insulation layer (generally EPS, XPS, PU, ​​etc.) and a decorative layer. Although the insulation layer can play a certain role in thermal insulation, its mechanical properties and durability It is difficult to meet the functional requirements of modern people for the wall structure. At the same time, only a single insulation layer is used on the surface of the external wall, which is prone to aging, deformation and other phenomena.
