Thermal insulation and energy-saving wall structure and preparation method thereof

Abstract

The invention provides a heat preservation and energy saving wall structure and a manufacturing method thereof. The wall structure comprises an elastic heat insulation weather-proof coating layer, a first cement waterproof mortar layer, a galvanized steel wire netting, a second cement waterproof mortar layer, a 108 neat cement paste layer and shale sintered porous bricks from outside to inside in sequence. The invention further relates to the manufacturing method of the wall structure. The wall structure has the advantages that crack prevention is achieved, the shale sintered porous bricks can be bonded to the wall structure firmly, heat is preserved, energy is saved, cementing bond between new concrete and old concrete and between the concrete and plastering mortar can be enhanced greatly, the maximum reflection can be achieved, the temperature of the surface of the outer wall can be lowered as many as 14 degrees, and building energy conservation can be achieved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials for building walls, in particular to a thermal insulation and energy saving wall structure and a preparation method thereof. Background technique [0002] In recent years, with the rapid economic and social development and the acceleration of urbanization, people's awareness of green energy conservation has been continuously enhanced, and green buildings and sustainable buildings have also been developed. Fully considering the coordination between buildings and the surrounding environment, the maximum Minimize energy consumption and environmental pollution. Insulation and energy saving of exterior walls in building production is an important part of green buildings and sustainable buildings. However, at present, the insulation of exterior walls is generally applied to the exterior walls with a certain thickness of inorganic thermal insulation mortar, but the bonding strength b...

Problems solved by technology

The traditional building wall insulation in our country is to use the method of thickening the wall thickness to achieve the purpose of insulation, not only the cost of the project is high, but also the waste of land resources is serious

[0004] With the needs of building development, a large number of wall insulation materials have also emerged. However, most wall insulation materials either consume a lot of building material resources and are expensive, or the strength of the material itself is not enough. In practical applications The quality is unstable, and the wall insulation layer is thicker, which is prone to hollowing, cracking, pulverization and other defects, which affects the quality of the building, and it is difficult to meet the standards of thermal insulation and energy saving.

[0005] At present, there are many wall insulation materials in the construction market, such as: one is the wall insulation board of the plate type, and the existing problems are: the production process is complicated, the space is large, and the wall insulation layer is poor in compression resistance , easy to produce cracks; the other is closed-cell vitrified microbead insulation material, after the material expands, the surface is uranized for waterproofing, but the cohesion of the material after uranization is poor, and it is easy to appear hollowing and cracking after being made into a wall The phenomenon

Another kind of wall insulation slurry material is made of asbestos, perlite, reinforcing agent, binder and water. Although it can achieve a certain insulation effect, its quality is unstable during use and transportation is also very difficult. It is convenient, and the asbestos in the material contains carcinogens that are harmful to human health. It is a material banned by the state, so it is inconvenient to promote and apply
