Wall internal and external combination heat-preservation system

Abstract

The invention relates to a wall internal and external combination heat-preservation system. The wall internal and external combination heat-preservation system is composed of a wall (4), an external hear-preservation layer and an internal heat-preservation layer and is characterized in that the external heat-preservation layer is composed of an anti-crack type cement leveling mortar layer (3), a building heat-preservation putty layer (2) and a building reflecting heat-insulation coating layer (1); and the internal heat-preservation layer is composed of a modified desulfurized gypsum heat-preservation mortar layer, an inner wall putty layer and an inner wall coating layer. The wall internal and external combination heat-preservation system is suitable for energy-saving and heat-preservationengineering for newly-built, rebuilt and expanded residential buildings and public buildings in regions hot in summer and cold in winter, regions hot in summer and warm in winter and parts of cold regions, and can be used for energy-saving transformation of outer walls of existing buildings, and the heat-insulation, heat-preservation and energy-saving effects of the buildings can be achieved completely.

Description

technical field [0001] The patent of the present invention relates to a combined thermal insulation system inside and outside a wall, which belongs to the technical field of building thermal insulation materials and wall thermal insulation systems. Background technique [0002] With the continuous, rapid and stable growth of my country's economy and the rapid development of construction, the per capita floor area will continue to increase, the requirements for residential comfort will become higher and higher, heating and air-conditioning facilities will increase rapidly, and building energy consumption will continue to increase. will increase substantially. With the increasing tension of global energy, people pay more and more attention to building energy saving and related thermal insulation materials and thermal insulation systems. Thermal insulation materials have become a hot spot in the application and research of building materials, and higher and higher requirements ...

AI Technical Summary

Problems solved by technology

Among the currently used thermal insulation materials, organic thermal insulation materials are the main ones. Organic thermal insulation materials have the characteristics of good thermal insulation effect and light weight, and a set of construction regulations and standards have been established. However, organic thermal insulation materials have obvious fire hazards. After burning, a large amount of toxic gas will be produced, which will cause serious damage to the human body until death; at present, other external wall insulation materials and external wall insulation systems cannot be well bonded to the wall substrate, and are prone to hollowing, cracking, Shedding and other phenomena

The current building exterior wall insulation system has a large bulk density, which increases the weight of the overall building, and the insulation performance is poor, which cannot fully achieve the purpose of building insulation and energy saving.
