Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of outer wall coating, specifically is outer wall latex paint coating structure with good sound insulation effect. BACKGROUND

[0002] In the field of architectural coatings, exterior wall latex paint is widely used due to its excellent physical properties and decorative effects. In the prior art, various exterior wall latex paint coating structures have been proposed to improve the sound insulation effect, waterproof performance and durability of the coating. For example, the utility model patent with publication number CN212078487U discloses an outer wall latex paint coating structure with good sound insulation effect. The structure neutralizes the alkaline solution flowing out of the wall through the acrylic fiber layer, eliminating the alkaline solution and preventing the precipitation of hydroxide, thereby enhancing the adhesion stability of the coating to the wall surface and increasing the service life. At the same time, the acrylic fiber layer has a certain attraction effect, making the sound insulation effect of the latex paint body better. However, the prior art has some deficiencies. For example, when the acrylic fiber layer reacts with the alkaline solution flowing out of the wall, a large amount of heat is generated, which is transferred to the latex base layer and the wall surface, easily causing the latex base layer and the wall surface to dry and age. In addition, the water produced by the neutralization reaction flows back to the wall surface through the through hole, causing damage to the wall surface.

[0003] To overcome the deficiencies of the prior art, the present application provides an outer wall latex paint coating structure that solves the above problems. Through specific structural design, the present application includes a toughness layer, a sound insulation layer, a waterproof layer, an acrylic fiber layer, a rubber plastic film, a reflective layer, and their connection methods, aiming to provide an outer wall latex paint coating structure with reasonable structure, good sound insulation effect, and resistance to aging and easy to fall off. SUMMARY

[0004] To overcome the deficiencies of the prior art, the present application provides an outer wall latex paint coating structure with good sound insulation effect, solving the problem of dry aging of the latex base layer and the wall surface when the acrylic fiber layer reacts with the alkaline solution flowing out of the wall, and the water produced by the neutralization reaction flowing back to the wall surface through the through hole, causing damage to the wall surface.

[0005] To achieve the above purposes, the utility model realizes the following technical scheme: an outer wall latex paint coating structure with good sound insulation effect, including a toughness layer, a sound insulation layer, a waterproof layer, and a reflective layer.

[0006] The toughness layer is located at the bottom layer.

[0007] The sound insulation layer is located above the toughness layer.

[0008] The waterproof layer covers the sound insulation layer.

[0009] The acrylic fiber layer is located on the upper end surface of the toughness layer, adjacent to the waterproof layer;

[0010] The rubber plastic film covers the upper surface of the acrylic fiber layer;

[0011] The reflective layer is located on the upper end surface of the rubber plastic film, and a plurality of semicircular ball bumps of the same material as the acrylic fiber layer are arranged between the top acrylic fiber layer and the rubber plastic film. The rubber plastic film is provided with a semicircular ball groove matched with the plurality of semicircular ball bumps, and the plurality of semicircular ball bumps extend into the semicircular ball groove.

[0012] Preferably, the sound insulation layer is composed of a multi-layer structure, including at least one layer of porous sound-absorbing material and one layer of waterproof and breathable film, wherein the porous sound-absorbing material is porous. This structure can effectively absorb and reduce noise, and the waterproof and breathable film ensures the waterproof performance of the material, so that the sound insulation layer can maintain its sound insulation effect in various environmental conditions.

[0013] Preferably, the surface of the acrylic fiber layer is coated with an adhesive, and the surface of the acrylic fiber layer is coated with an adhesive on the surface of the plurality of semicircular ball bumps. The surface of the semicircular ball bump on the surface of the acrylic fiber layer is bonded to the corresponding groove on the rubber plastic film through the adhesive, which enhances the connection strength between the acrylic fiber layer and the toughness layer. The cooperation of the semicircular ball bump and the groove provides better mechanical locking, making the overall structure more stable and reducing the risk of interlayer separation caused by external force.

[0014] Preferably, the waterproof layer is composed of a multi-layer composite film, including at least one layer of high molecular waterproof film and one layer of reinforced polyester mesh. The thickness of the high molecular waterproof film is 0.1-0.3mm, and the mesh size of the polyester mesh is 3-5mm. The combination of high molecular waterproof film and reinforced polyester mesh provides excellent waterproof performance, while the reinforcing effect of the mesh improves the tear resistance and wear resistance of the waterproof layer, so that the waterproof layer remains light and thin while having high strength.

[0015] Preferably, the reflective layer is composed of a plurality of metal foils and transparent protective films. The thickness of the metal foil is 0.03-0.08mm, and the thickness of the transparent protective film is 0.02-0.1mm. It has ultraviolet resistance and weather resistance. The metal foil can effectively reflect light and heat, while the transparent protective film protects the metal foil from ultraviolet rays and harsh weather, prolonging the service life of the reflective layer and maintaining the appearance and performance of the material.

[0016] Preferably, the surfaces of the hemispherical protrusions on the acrylic fiber layer and the hemispherical grooves on the rubber plastic film are coated with a layer of anti-slip and wear-resistant material, which is silicone rubber or polyurethane with a thickness of 0.1-0.3 mm, to improve the durability and stability of the connecting mechanism. The anti-slip and wear-resistant coating of silicone rubber or polyurethane enhances the friction between the protrusions and grooves, preventing slippage. At the same time, the improved wear resistance reduces wear caused by long-term use, thereby improving the durability and reliability of the connecting mechanism.

[0017] This utility model provides an exterior wall latex paint coating structure with good sound insulation. It has the following beneficial effects:

[0018] (1) The sound-insulating exterior wall latex paint coating structure effectively solves the problem of damage to the wall caused by heat and moisture generated by the neutralization reaction by setting a mechanical locking structure of hemispherical protrusions and hemispherical grooves between the acrylic fiber layer and the rubber plastic film. The mechanical locking structure provides a stronger physical connection and reduces the stress caused by environmental changes in the coating. At the same time, the neutralization reaction characteristics of the acrylic fiber layer are designed to take place inside the coating, avoiding the direct impact of heat and moisture on the wall, thus providing excellent heat resistance and waterproof performance.

[0019] (2) The sound-insulating exterior wall latex paint coating structure solves the problem that water vapor cannot be effectively discharged in traditional coating structures by adding a waterproof and breathable membrane in the sound insulation layer. The material properties of the waterproof and breathable membrane allow water vapor molecules to pass through while preventing liquid water from penetrating, effectively reducing the accumulation of moisture inside the coating and avoiding problems such as blistering and peeling of the coating due to excessive humidity, thereby improving the waterproof performance and service life of the coating.

[0020] (3) The sound-insulating exterior wall latex paint coating structure consists of multiple layers of metal foil and transparent protective film. The metal foil has high reflectivity, effectively reflecting ultraviolet rays and heat in sunlight, reducing the risk of fading or aging of the coating due to long-term ultraviolet radiation, ensuring that the coating can maintain its performance and appearance under various harsh climatic conditions, and enhancing the protective function and decorative effect of the coating.

[0021] This solves the problem that when the acrylic fiber layer reacts with the alkaline solution flowing from the wall, it can easily lead to the drying and aging of the latex base layer and the wall surface. The water produced by the neutralization reaction will flow back to the wall surface through the pores, causing damage to the wall surface. Attached Figure Description
