Example 1

As shown in Figures 1 and 2, an outdoor weather-resistant decorative panel includes a decorative panel base layer 4, around which two groups of composite layers are stacked. The two groups of composite layers are symmetrically distributed on both sides of the decorative panel base layer 4 with the decorative panel base layer 4 as a reference plane. Each group of composite layers includes a foam board skin layer 3, an adhesive layer 2 and a surface decorative layer 1 which are stacked in sequence.

The decorative board base layer 4 is made of polyvinyl chloride as the main raw material, with additives such as foaming agent, stabilizer, lubricant, etc. added, and is made into a PVC foam board through foaming and plasticization. It has excellent flame retardant, waterproof and chemical resistance. The thickness of the decorative board base layer 4 is 14 to 16 mm. Within this thickness range, the stability of the base structure is ensured while the weight of the base layer is moderate.

The foam board skin layer 3 is made of the same PVC foam board as the decorative board base layer 4, and the thickness of the foam board skin layer 3 is 0.5 to 0.8 mm. The foam board skin layer 3 is in contact with the surfaces of both ends of the decorative board base layer 4, and has high impact resistance and wear resistance, and is anti-corrosion, moisture-proof, water-resistant, and insect-proof, and is not easy to age, so as to protect the decorative board base layer.

The adhesive layer 2 is PUR adhesive, and the thickness of the adhesive layer 2 is 0.05 to 0.1 mm. The adhesive layer 2 is in contact with the surface of the foam board skin layer 3, and the surface area of the adhesive layer 2 does not exceed the surface area of the foam board skin layer 3. Within this thickness range, the adhesive layer 2 can ensure the bonding stability between the foam board skin layer 3 and the surface decorative layer 4 while avoiding the outward leakage of the adhesive.

The surface decoration layer 1 is an HPL board, also known as a fireproof board. The thickness of the surface decoration layer 1 is 0.55 to 0.65 mm. The surface decoration layer 1 is bonded to the surface of the adhesive layer 2. The surface of the surface decoration layer 1 is a veneer with colorful patterns.

The implementation principle of Example 1 of the present application is: a PVC foam board with advantages such as low density, low thermal conductivity, good sound absorption performance, flame retardant, waterproof and chemical resistance is used as the base layer 4 of the decorative board, and two groups of composite layers are symmetrically arranged on both sides of the base layer 4 of the decorative board. The two groups of composite layers clamp the base layer of the decorative board to make the overall structure of the decorative board stable, and the performance of the two sides of the decorative board is the same, so it is convenient to use without identifying the front and back during construction and installation. The composite layer is formed by stacking the foam board skin layer 3, the PUR material glue layer 2 and the HPL material surface decoration layer 1 in sequence. The first layer of the foam board skin layer 3 provides buffer protection for the base layer 4 of the decorative board to prevent the base layer of the decorative board from being worn; the second layer of the glue layer 2 is bonded by the PUR glue with good water resistance, weather resistance and chemical resistance to stabilize the bonding between the foam board skin layer 3 and the surface decoration layer 1; the third layer of the surface decoration layer 1 provides secondary protection for the base layer 4 of the decorative board through the high temperature resistant and structurally stable HPL board. The double protection of the base layer 4 of the decorative board is achieved by the setting of the composite layer to improve the overall weather resistance of the board and increase the service life of the board in the outdoor environment.

It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the basic features of the present application.
