Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall paint layer structures, in particular to a waterproof and anti-shedding exterior wall paint layer structure. Background Art

[0002] At present, exterior wall paint is an important material for protecting the exterior facade of a building. Its performance is directly related to the appearance and service life of the building. In house construction, exterior wall paint can generally improve the waterproof performance and service life of the building facade. At present, exterior wall paint is used to paint the exterior walls of buildings.

[0003] The use of coatings in my country's construction industry is very extensive. The main types of exterior wall coatings include styrene acrylate, pure acrylate, silicone modified acrylate, fluorocarbon and other synthetic resin emulsion thin exterior wall coatings. In addition, there are elastic exterior wall coatings, sand wall exterior wall coatings, real stone paint exterior wall coatings, multi-layer patterned exterior wall coatings and other synthetic resin emulsion thick coatings and imitation metal curtain wall coatings (metallic paints), etc. Due to their excellent performance and compliance with energy saving and environmental protection, the above-mentioned coatings have a good development direction.

[0004] For example, Chinese patent CN207794474U discloses a breathable exterior wall paint layer structure, comprising a putty layer coated on the outer surface of the exterior wall, a sealing primer layer coated on the outer surface of the putty layer, and an exterior wall latex paint layer coated on the outer surface of the sealing primer layer; a composite breathable layer is provided between the sealing primer layer and the exterior wall latex paint layer, and the composite breathable layer comprises an EVA resin coating, a nano-ceramic powder coating, a mesh polymer coating, an inorganic polymer coating, and a phenolic epoxy resin coating arranged in sequence. The composite breathable layer of the above structure is provided in the utility model, so that the exterior wall paint layer structure as a whole has very good air permeability. After multiple use tests, the air permeability of the exterior wall paint layer structure applied for is 50.6 ml / m2·72 hours·0.2 MPa or more, which effectively avoids the cracking phenomenon caused by high temperature and low temperature cycles after the gas is sealed on the wall surface, greatly improving the overall performance of the exterior wall paint layer structure.

[0005] Although the above patent effectively avoids the cracking phenomenon caused by high and low temperature cycles after the gas is sealed on the wall surface, and greatly improves the overall performance of the exterior wall paint layer structure, the patent only uses the exterior wall latex paint layer as a waterproof layer. Under the long-term immersion and corrosion of rainwater, the above breathable exterior wall primer paint layer structure is prone to cracking and peeling, which will cause the above coating structure to be destroyed and leak. At this time, rainwater will leak into the construction joint and cause shedding damage to the exterior wall. Utility Model Content

It solves the problem of using only the exterior wall latex paint layer as a waterproof layer. Under the long-term immersion and corrosion of rainwater, the above-mentioned breathable exterior wall primer paint layer structure is prone to cracking and peeling, which will cause the above-mentioned coating structure to be damaged and leak. At this time, rainwater will leak into the construction joint and cause shedding and damage to the exterior wall.

[0021] By adopting this technical solution, the internal structure can be protected from erosion by the external environment through the exterior finishing layer.

[0022] Furthermore, at least two bolt slots are evenly distributed on the upper surface of the outer wall.

[0023] By adopting this technical solution, the stability of the connection between the exterior wall and the exterior wall paint layer can be improved through the bolt groove, reducing the possibility of falling off.
