Exterior wall external thermal insulation coating veneer structure

Abstract

The invention discloses an exterior wall external thermal insulation coating veneer structure. A bonding layer, a thermal insulation layer, a fire-proof layer, a first anti-crack layer, a reinforcing material layer, a second anti-crack layer and a coating layer are sequentially arranged on the outer surface of a base wall from inside to outside, all layers are dried and solidified to be integrally combined with the base wall, the coating layer is formed by sequential lamination of an anti-microbial layer, a thermal insulation coating layer and a sound absorbing layer, and the anti-microbial layer, the thermal insulation coating layer and the sound absorbing layer sequentially and uniformly coat the surface of the second anti-crack layer. According to the exterior wall external thermal insulation coating veneer structure, the thermal insulation effect is good, the service life is long, various functions are achieved, and requirements of people for wall decorations can be met.

Description

technical field [0001] The invention relates to the technical field of building materials used in the building industry, more specifically, it relates to an exterior thermal insulation paint finish structure. Background technique [0002] At present, my country's energy-saving level in the construction industry still has a certain distance compared with developed countries. According to relevant statistics, the energy consumption per unit building area in my country is equivalent to more than three times that of developed countries with the same climate. It is stipulated in the energy-saving rules that my country's civil building energy-saving standards are classified as mandatory standards. For projects that do not meet my country's building energy-saving standards, they are resolutely refused to approve and start construction. It is precisely under the guidance of the country's energy-saving regulations and policies Only under this condition can the energy-saving level of va...

Problems solved by technology

In such an external thermal insulation system for external walls, the finishing paint layer only has decoration and general waterproof functions, does not have thermal insulation functions, and cannot meet more needs of the public, which has certain limitations on the protection of the entire system property, and in summer, it is prone to fire hazards. Such a thermal insulation system cannot resist the high temperature generated by fire hazards at all, and under the sunlight, the temperature of the wall is very high, and the thermal insulation performance of the polystyrene board makes the coating layer and The heat accumulated in the plastering mortar layer is difficult to conduct and diffuse, and if there is a sudden heavy rain, the temperature will drop sharply. Such a huge temperature difference will cause irreversible thermal shrinkage deformation of the polystyrene board, and it will also cause severe damage to the plastering mortar layer and the finish paint layer. Cracking, losing the function of decoration and protection, especially serious, once the surface layer of the external thermal insulation structure of the external wall is cracked, rainwater or water vapor will enter the insulation layer of polystyrene board and the adhesive mortar layer along the crack, which will make the polystyrene board stick As a result, the external insulation structure will fall off; and as we all know, in real life, the facing structure of the external wall is very easy to breed bacteria. After a long time, the wall will be peeled off, and the external insulation of the entire external wall will also be damaged. The structure will fall off, causing a safety hazard
