Description

Technical Field

[0001] The utility model relates to the technical field of building coatings, in particular to a mildew-proof and carbonization-proof building wall coating composite structure. Background Art

[0002] Building wall coatings mainly have decorative and protective functions. The protective function refers to protecting the building wall from damage and protecting the wall from or less affected by the environment, thereby increasing the service life of the building wall. At present, the main body of the building wall is concrete material. The Ca in the concrete material 2+ Mg 2+ 、Al 3+ Soluble salts such as carbonized salts are prone to water-soluble migration. When they come into contact with CO2 in the air, they are carbonized, forming salt frost on the wall. In addition, when the humidity in the air is high, water vapor penetrates into the paint, causing the wall to become damp and moldy. Salt frost and mold not only affect the appearance of the wall, but also make the wall more prone to hollowing and cracking, affecting the durability of the wall. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the present application provides a mildew-proof and carbonization-proof building wall paint coating composite structure, which comprises a wall solid layer, a putty layer and a function enhancement layer from the inside to the outside; wherein the function enhancement layer comprises an anti-carbonization paint layer, an anti-mildew paint layer and a wear-resistant layer from the inside to the outside.

[0005] In some specific implementations, the wall solidifying layer uses a wall curing agent.

[0006] In some specific embodiments, the anti-carbonization coating layer is made of a cement-based composite material modified by a polymer emulsion.

[0007] In some specific embodiments, the anti-mildew coating layer uses an inorganic silicate-based anti-mildew coating.

[0008] In some specific embodiments, the wear-resistant layer adopts wear-resistant ceramic coating.

[0009] In some specific embodiments, the above-mentioned building wall paint coating composite structure also includes a repairing and leveling layer, and the repairing and leveling layer is located on the inner side of the wall solidifying layer and is bonded to the wall solidifying layer as a whole.

[0010] In some specific embodiments, the repair leveling layer is made of cement mortar, preferably crack-resistant cement mortar.

[0011] Compared with the prior art, this application has the following advantages and beneficial effects:

[0012] The strengthening layer of the present application adopts a wall curing agent, which can be used as an interface treatment material and can also give the wall a certain waterproof and mildew resistance. The functional enhancement layer is used to further enhance the waterproof, mildew and carbonization resistance of the wall. The anti-carbonization coating layer is a cement-based composite material modified by a polymer emulsion. The polymer emulsion and cement undergo a cross-reaction chain to form a network structure composed of cement hydrates and polymers. After painting, a high-strength, tough and durable elastic film is obtained, which can prevent the penetration of CO2, chloride ions, etc., and also has a certain waterproof property. The mildew-proof coating layer is an inorganic silicate-based mildew-proof coating. The inorganic silicate penetrates into the anti-carbonization coating layer and is integrated with the anti-carbonization coating layer through petrochemical action, further improving the waterproof performance; at the same time, the mildew-proof coating layer contains antibacterial ingredients that can inhibit mold, thereby forming a coating film with many advantages such as mildew resistance, antibacterial resistance and waterproofness on the surface of the anti-carbonization coating layer. The wear-resistant layer is used to improve the wear resistance of the wall and play a role in protecting the wall.

[0013] Therefore, the present application can enhance the waterproof, mildew-proof, carbonization-proof and wear-resistant properties of the wall through the synergistic effect of each layer, thereby enhancing the durability of the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present application will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0018] Example 1

[0019] See also Figure 1The wall paint coating composite structure of the present embodiment includes a wall solidifying layer 20, a putty layer 30 and a function enhancement layer 40 from the inside to the outside. The wall solidifying layer 20 is mainly used to improve the interfacial adhesion of the wall surface, and also provides sealing effect, curing effect and waterproof and mildew-proof effect. The putty layer 30 is mainly used to ensure the smoothness of the wall surface, which is convenient for the subsequent construction of the function enhancement layer 40. The function enhancement layer 40 is mainly used to enhance the mildew-proof and carbonization-proof performance of the paint coating composite structure, and enhance the durability of the wall surface.

[0020] In this embodiment, the material of the wall solidification layer 20 is a wall curing agent, also called a wall hardener. The wall curing agent is a green and environmentally friendly high-performance interface treatment material with excellent permeability. It can fully penetrate into the interior of the wall, make the wall dense through adhesive bonding, and improve the interface adhesion, so that the putty layer and the wall are tightly bonded, which can avoid hollowing, cracking, sand and dust falling, etc. Compared with traditional interface agents, wall curing agents also have excellent sealing effects, curing effects, and waterproof and mildew-proof effects.

[0021] In this embodiment, the wall-solidifying layer 20 is located on the outer side of the wall surface, and the putty layer 30 is located on the outer side of the wall-solidifying layer 20. The wall surface is a concrete wall surface, and the wall surface can be kept clean and dry during construction. During construction, the wall-solidifying layer 20 is formed on the wall surface by spraying or rolling, and multiple layers can be sprayed or rolled.

[0022] In this embodiment, the function enhancement layer 40 includes an anti-carbonization coating layer 41, an anti-mildew coating layer 42 and a wear-resistant layer 43 from the inside to the outside. The anti-carbonization coating layer 41 is applied to the outside of the putty layer 30, with a thickness of 0.70mm-0.80mm, and is mainly used to prevent CO2, chloride ions, oxygen, water, etc. in the environment from entering the wall. The anti-carbonization coating layer 41 is made of a cement-based composite material modified by a polymer emulsion, such as CPC concrete anti-carbonization protective coating. The polymer emulsion and cement undergo a cross-reaction chain to form a network structure composed of cement hydrates and polymers. After painting, a high-strength, tough and durable elastic film can be formed on the putty layer 30. It is environmentally friendly, can prevent the penetration of CO2, chloride ions, etc., and also has sealing properties.

[0023] The anti-mildew coating layer 42 is applied to the outside of the anti-carbonization coating layer 41 by spraying, rolling or brushing, with a thickness of 0.3mm-0.5mm, and is mainly used to prevent water and moisture and inhibit the formation of mold. The anti-mildew coating layer 42 adopts an inorganic silicate-based anti-mildew coating, with inorganic silicate as the main film-forming substance. The inorganic silicate component penetrates into the anti-carbonization coating layer 41, and is integrated with the anti-carbonization coating layer 41 through petrochemical action, forming a coating film with many advantages such as mildew prevention, antibacterial, and waterproof on the surface of the anti-carbonization coating layer 41.

[0024] The wear-resistant layer 43 is applied to the outer side of the mildew-proof paint layer 42 by spraying, rolling or brushing, with a thickness of 0.1mm-0.3mm, to further improve the wear resistance of the paint coating. The wear-resistant layer 43 can be made of wear-resistant ceramic paint.

[0025] Example 2

[0026] Based on the embodiment 1, this embodiment further comprises a repairing and leveling layer 10, which is located between the wall surface and the wall solidifying layer 20. The repairing and leveling layer 10 is applied to the wall surface and bonded to the wall solidifying layer 20. The repairing and leveling layer 10 is used to fill defects such as cracks and holes on the wall surface, and to level the wall surface to ensure the flatness of the wall surface. In this embodiment, the repairing and leveling layer 10 is selected from cement mortar, preferably anti-cracking cement mortar.

[0027] During actual construction, whether to apply a repairing leveling layer 10 is selected according to the degree of wall surface defects.
