Problems solved by technology

For ceramic panels, first, the production process is complex, heavy, fragile, and troublesome in construction; second, it does not have the functions of shock absorption, heat insulation, and sound insulation.
For wooden panels, the waterproof and anti-corrosion properties are poor, and a large amount of use wastes national forest resources
Composite wall panels are also used for wall decoration now. The patent of Chinese Patent Publication No. CN202324474U discloses a PVC wood-plastic composite decorative board. This PVC wood-plastic composite decorative board includes an upper and lower two-layer structure. It is a PVC wood-plastic crusted foam board, and the veneer has a wear-resistant upper surface. The veneer can be: PVC film, wood veneer, waterproof board, melamine paper, PET film, aluminum skin, etc. This PVC wood-plastic composite decorative board has no Methanol, waterproof, anti-moth, light weight, sound insulation, heat insulation, flame retardant, self-extinguishing, moisture-proof, anti-corrosion, mildew-proof, and shock-proof. The disadvantages are: first, the lower layer is PVC wood-plastic crust foam board , in the process of preparing PVC wood-plastic crust foam board, wood fiber or plant fiber needs to be added, and the production process is complicated; the second is that the veneer is PVC film, wood veneer, waterproof board, melamine paper, PET film, aluminum skin, etc., wall panels The outer surface has poor wear resistance, is easy to scratch, and has a short service life

Embodiment 1

[0025] Process 1. Make a transparent film with a colorless UV coating on the outer surface according to the conventional process.

[0026] Process 2. Make a color film with imitation stone patterns according to the conventional process.

[0027] Process 3. Make polyvinyl chloride sheets according to the conventional process, with a thickness of 0.5mm.

[0028] Process 4. Make polyvinyl chloride skinned foam board according to the conventional process.

[0029] Step 5. The transparent film, the color film layer, and the polyvinyl chloride sheet are stacked sequentially from top to bottom, and hot-pressed to form an upper composite layer.

[0030] This hot pressing process is divided into five stages, and the process parameters of each stage are as follows:

[0031]

[0032] Step 6. Spray the upper composite layer once, and the amount of the topcoat is 0.6-0.7g / 12″x12″.

[0033] The drenching process parameters are as follows:

Abstract

The invention discloses a PVC (polyvinyl chloride) composite shingle which is provided with a multilayer composite structure and comprises an abrasion-resistant layer, a color film layer, a substrate and a base material from the top down, wherein the base material is a crusted foaming board; the abrasion-resistant layer is a transparent film with a colorless UV (ultraviolet) coating on the external surface of the film; the substrate is a PVC sheet about 0.2-1mm thick; the base material is the PVC crusted foaming board, or a PVC / CPVC (chlorinated polyvinyl chloride) crusted foaming board; and the color film layer is a color film with decorative board patterns such as a woody pattern and a stone imitation pattern. The composite shingle is simple in manufacturing technology and has better decoration performance; the abrasion resistance of the external surface of the composite shingle and the structural strength of the composite shingle can be improved significantly; and the service life of the composite shingle can be prolonged.

Description

technical field [0001] The invention relates to a decorative plate, in particular to a wall panel. Background technique [0002] Existing panels that are used for wall decoration mostly adopt ceramic panels and wooden panels. For ceramic panels, first, the production process is complex, heavy, fragile, and troublesome in construction; second, they do not have the functions of shock absorption, heat insulation, and sound insulation. For wooden panels, the waterproof and anti-corrosion properties are poor, and a large amount of use wastes national forest resources. Composite wall panels are also used for wall decoration now. The patent of Chinese Patent Publication No. CN202324474U discloses a PVC wood-plastic composite decorative board. This PVC wood-plastic composite decorative board includes an upper and lower two-layer structure. It is a PVC wood-plastic crusted foam board, and the veneer has a wear-resistant upper surface. The veneer can be: PVC film, wood veneer, water...
