Technical Field
[0001] This utility model relates to the field of interior decoration technology, and in particular to a high-density, three-proof SPC stone-crystal composite wall panel. Background Technology
[0002] SPC stone crystal wall panels are an environmentally friendly building material made of stone powder and polymer materials. They are waterproof, moisture-proof, fireproof, and formaldehyde-free. They are commonly used for interior wall and ceiling decoration, and are especially suitable for humid environments such as kitchens and bathrooms. Their surface can imitate various textures such as wood grain and stone grain, which can not only meet the aesthetic needs, but also have the advantages of SPC material being lightweight, durable and easy to install. It is a modern decoration solution that can replace traditional tiles and wallpaper.
[0003] In existing technologies, wall panels still have shortcomings in terms of waterproofing. Most wall panels have only one waterproofing performance, relying solely on a simple coating for waterproofing and moisture protection. They are prone to water seepage when exposed to heavy rainfall, which is difficult to drain and reduces their service life. Installation often uses a single connection method, which is prone to loosening after long-term use. Furthermore, it is difficult to balance overall structural strength and lightweight design, and cannot meet the requirements for three-proof and structural stability in high humidity environments. Therefore, a high-density three-proof SPC stone-crystal composite wall panel is needed. Utility Model Content

[0022] Structural Description: Inner sandwich panel 1: As the core support layer of the composite wall panel, it is connected to the dovetail tenon 6 of the outer wall panel 3 through the dovetail grooves 2 on both sides. The honeycomb structure 11 in the internal cavity 10 provides a lightweight and high-strength support system. Dovetail groove 2: It forms a sliding fit structure with the dovetail tenon 6 of the outer wall panel 3, realizing quick positioning and initial fixation during assembly. The groove depth ensures that the tenon and mortise have the ability to resist lateral displacement after the tenon and mortise are engaged. Exterior wall panel 3: As an external protective layer, it is dynamically connected to the inner sandwich panel 1 through dovetail tenon 6. The surface protrusion 4 increases the friction coefficient. The specific material is SPC stone crystal wall panel, which is mainly composed of natural stone powder and high molecular resin through high temperature extrusion. It has good waterproof, moisture-proof and mildew-proof performance. Raised Ribs 4: Distributed on the surface of the exterior wall panel 3, the three-dimensional texture design enhances the surface's scratch resistance and forms a drainage channel to assist in rainwater dissipation; Water guide eaves 5: A chamfered structure located at the top edge of the exterior wall panel 3, which directs the water flow from above to both sides to avoid vertical penetration, forming a synergistic waterproofing mechanism with the waterproof layer 14; Dovetail tenon 6: As a key connecting component between the outer wall panel 3 and the inner sandwich panel 1, its trapezoidal cross-section design generates a self-locking effect when subjected to tensile force, and forms a double fixation with the countersunk bolt 9; Filling grooves A7 and B8: respectively opened on the mating surfaces of the inner sandwich panel 1 and the outer wall panel 3, and after the sealant is injected, they form a continuous elastic sealing strip to compensate for component installation tolerances and block capillary water seepage. Countersunk bolt 9: A threaded fastener that penetrates the outer wall panel 3 and the inner sandwich panel 1, providing final rigid fixing force. The countersunk design avoids the protrusion affecting the flatness of the wall surface. Cavity 10: The weight-reducing structure inside the inner sandwich panel 1 is achieved by optimizing the cavity volume to balance the amount of material used and mechanical properties; Honeycomb structure 11: a hexagonal unit array filling the cavity 10, achieving high compressive strength with minimal material consumption, while also possessing acoustic damping characteristics; Waterproof membrane 12: A double-layer polymer film applied to the surface of the inner sandwich panel 1 to block moisture from penetrating through the capillaries of the panel; Installation groove 13: The prefabricated waterproof layer 14 is embedded in the exterior wall panel 3. The groove wall and the waterproof layer 14 are interference fit to ensure reliable sealing. Waterproof layer 14: Made of an elastomeric material that matches the contour of the mounting groove 13, forming a dynamic seal at the joints of the outer wall panel 3; Drainage outlet 15: Drainage channel at the bottom of exterior wall panel 3, which directs any condensate or rainwater that may seep in to the external environment; Dustproof net 16: A microporous filter covering the water inlet 15 to prevent insects, dust and other impurities from entering the interior of the wall panel and causing blockage.
