Description

Technical Field

[0001] This utility model relates to the field of building wall protection technology, specifically to a multi-layer alkali-resistant protective wall structure. Background Technology

[0002] Existing wall surfaces are typically made of ceramic tiles or stone. The drawbacks of this structure are: high energy consumption, environmental pollution, lack of energy conservation and environmental protection, heavy weight, safety concerns, easy water seepage, and high construction costs.

[0003] However, on-site application of commercially available interior and exterior wall coatings has the following drawbacks: 1. Complex application process, long construction period, and significant susceptibility to weather conditions. 2. Cracking of the substrate causes paint cracking. 3. Inadequate worker skills and on-site management severely affect coating quality and application results. 4. High labor costs.

[0004] Alkali-resistant treatment is a crucial step in the decoration and protection of building walls. Traditional wall treatment methods often only provide a single protective effect and cannot comprehensively solve problems such as the penetration of alkaline substances and coating peeling. Therefore, a wall structure that can provide multi-layer protection and effectively resist alkali is needed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer alkali-resistant protective wall structure to solve the technical problems of alkaline substance penetration and coating peeling in existing technologies. Through the composite use of multiple materials, it effectively prevents the penetration of alkaline substances into the wall, improving the durability and decorative properties of the wall surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a multi-layer alkali-resistant protective wall structure, including an alkali-resistant penetrating primer layer, an alkali-resistant putty layer, an alkali-resistant sealing primer layer, and a flexible high-viscosity sealing coating layer, wherein the alkali-resistant penetrating primer layer, the alkali-resistant putty layer, the alkali-resistant sealing primer layer, and the flexible high-viscosity sealing coating layer are connected sequentially from bottom to top on the surface of the wall.

[0008] In this invention, the alkali-resistant primer coating uses a silane-modified resin. When applied to the surface of the wall, the alkali-resistant primer coating penetrates into the substrate to a depth greater than 2 mm. Furthermore, the silane-modified resin used in the alkali-resistant primer coating has excellent permeability, enabling it to penetrate deep into the wall to form a dense protective layer, effectively preventing the penetration of alkaline substances and enhancing adhesion.

[0009] The alkali-resistant penetrating primer has good alkali resistance, preventing the coating from turning alkali and discoloring.

[0010] In this invention, the alkali-resistant putty layer is applied to the alkali-resistant penetrating primer layer by troweling or spraying, and the thickness of the alkali-resistant putty layer is 1~2mm.

[0011] Furthermore, the alkali-resistant putty layer is made of environmentally friendly materials and has excellent adhesion and crack resistance. It can effectively fill wall imperfections, provide a smooth base for painting, and is used for leveling walls.

[0012] In this invention, the alkali-resistant sealing base coating is applied to the alkali-resistant putty layer by roller coating, brush coating or spray coating, and the thickness of the alkali-resistant sealing base coating is 100-150μm.

[0013] Furthermore, the alkali-resistant sealing primer mainly uses silicone rubber-modified epoxy resin and silicone rubber-modified acrylic resin, which can form a dense film that effectively seals the micropores of the wall surface, prevents the seepage of alkaline substances, has good sealing properties, prevents water vapor penetration, and reduces the risk of wall dampness. It also improves the fullness and uniformity of the coating film, ensuring the coating effect of the topcoat.

[0014] In this invention, the flexible high-viscosity sealing coating is applied to the alkali-resistant sealing base coating by roller coating or spraying, and the thickness of the flexible high-viscosity sealing coating is 200-350μm.

[0015] Furthermore, the flexible, high-viscosity sealing coating primarily uses silicone rubber resin, which is highly elastic and viscous, forming a dense film. It employs a low-VOC formula, making it environmentally friendly and healthy, suitable for both indoor and outdoor use. It possesses excellent flexibility, capable of adapting to minor deformations of the wall and preventing coating cracking.

[0016] Furthermore, the flexible high-viscosity sealing coating cannot be replaced by other coatings.

[0017] Based on the above technical solution, the embodiments of this utility model can produce at least the following technical effects:

[0018] (1) The multi-layer alkali-resistant protective wall structure provided by this utility model adopts a multi-layer structure design, with each layer progressively preventing the penetration and seepage of alkaline substances.

[0019] (2) The multi-layer alkali-resistant protective wall structure provided by this utility model, which combines an alkali-resistant penetrating primer layer and an alkali-resistant putty layer, provides basic alkali-resistant protection while leveling the wall surface.

[0020] (3) The multi-layer alkali-resistant protective wall structure provided by this utility model, with the use of alkali-resistant sealing base coating and flexible high-viscosity sealing coating, further enhances the protective performance of the wall and improves the durability and decorative properties of the wall.

[0021] (4) The multi-layer alkali-resistant protective wall structure provided by this utility model is suitable for various building walls, especially for exterior and interior walls with high requirements for durability and decoration. Attached Figure Description
