Description

PVC board for architectural decoration

Technical Field

The utility model relates to a PVC (polyvinyl chloride) plate for architectural decoration, belonging to the technical field of architectural decoration materials.

Background

At present, the surface treatment in the aluminum veneer decoration industry generally uses a fluorocarbon paint spraying process, and because an organic solvent is used in the spraying process and is volatilized into the air after being baked, the VOC emission is too high, manufacturers try to change oil into water or oil into powder from the coating angle, or select other processes to directly replace the whole spraying process.

In terms of replacing the spraying process, the common mode on the market at present is to use a pre-surface treatment plate, such as a roller coating plate, a PVC film coating plate and the like, an aluminum veneer manufacturer can obtain raw materials with surface treatment from a supplier and directly perform sheet metal processing, so that the spraying process is omitted, and the production efficiency can be greatly improved for some special forms of surface treatment, such as stone imitation, wood imitation and the like. However, the method has an obvious defect that the surface treatment layer is formed before the sheet metal is processed, and the welding wire filling process can damage the surface treatment layer due to the welding of the gap between the folded edge and the folded edge, so that related products in the market are directly applied to architectural decoration without welding at the bending and splicing positions. Due to the fact that welding is not conducted, the mode is difficult to meet requirements and has obvious limitation when the folded edge bears force or the edge is exposed.

Disclosure of Invention

The utility model aims to provide a PVC plate for architectural decoration aiming at the bottleneck of the application of a precoated plate. The technical problem to be solved by the utility model is realized by adopting the following technical scheme:

a PVC board for architectural decoration comprises an aluminum alloy base plate, a modified PVC base film, a perfluoro printing film and a PVDF functional surface film. The aluminum alloy base plate is arranged at the lowest layer, the modified PVC base film is arranged on the aluminum alloy base plate, the perfluorinated printing film is covered on the modified PVC base film, and the PVDF functional surface film is covered on the perfluorinated printing film; and the periphery of the PVC plate is provided with folded edges.

The aluminum alloy base plate is made of aluminum alloy 3003H24 with the thickness of 1-3 mm.

The modified PVC base film is a base film of which the weather resistance and the adhesive force are enhanced by modifying a PVC film.

The perfluorinated printing film consists of a fluorine monomer and pigment and filler, and the ultra-high fluorine ratio can ensure the high weather resistance of the PVC film.

The PVDF functional surface film is colorless and transparent, is a functional film taking PVDF resin as a main film forming substance, and has the function of further enhancing the overall weather resistance of the PVC film.

The utility model has the beneficial effects that the multilayer film with strong weather resistance is covered on the aluminum alloy base plate, so that the weather resistance of the PVC decorative plate is greatly improved, the forming technology is used in the manufacturing process of the PVC decorative plate, the current situation that the PVC decorative plate is not welded in application is changed, the PVC decorative plate can be more widely applied to the outer wall decoration and other fields like an aluminum veneer, and the PVC plate has the possibility of replacing the traditional spray plate.

FIG. 1 is a schematic view of the PVC board structure for architectural decoration according to the present invention;

in the figure, 1 is an aluminum alloy base plate; 2 is a modified PVC base film; 3 is a perfluor printing film; and 4 is a PVDF functional surface film.

Detailed Description

A specific embodiment of the present invention is shown in fig. 1.

As shown in figure 1, the PVC plate for architectural decoration comprises an aluminum alloy base plate 1, a modified PVC base film 2, a perfluorinated printing film 3 and a PVDF functional surface film 4. The aluminum alloy base plate 1 is arranged at the lowest layer, the modified PVC base 2 film is arranged on the aluminum alloy base plate, the perfluorinated printing film 3 is covered on the modified PVC base film 2, and the PVDF functional surface film 4 is covered on the perfluorinated printing film 3; the edges of the PVC plate are folded.

The aluminum alloy base layer 1 of the present embodiment is made of 3003H24 aluminum alloy with a thickness of 1.0-3.0 mm.

The modified PVC base film 2 of this embodiment is the base film of its weatherability of PVC membrane through the modification reinforcing and adhesive force, and its main function lies in bearing perfluor printing film and PVDF function epiphragma to present different surface effects, and make its bonding on aluminium alloy substrate board, can use on the outer wall, simultaneously, make the PVC membrane possess certain pliability, the subsequent processing of being convenient for.

The perfluoro printing film 3 of the embodiment mainly comprises a fluorine monomer and pigment and filler, the ultra-high fluorine ratio can ensure the high weather resistance of the PVC film, and the color stability of the printing film is greatly guaranteed due to the large-scale coloring of the modified PVC base film 1.

The PVDF functional surface film 4 of the embodiment is a colorless and transparent functional film which takes PVDF resin as a main film forming substance, and has the functions of further enhancing the overall weather resistance of the PVC film and ensuring that the PVC plate has good chemical resistance, impact resistance, wear resistance and self-cleaning performance when being used on an outer wall.

As shown in fig. 1, the production process of the PVC plate for architectural decoration in this embodiment is a laminating process and an automatic sheet metal process. The film pasting process is to use a PVC film, an outdoor adhesive and an aluminum alloy plate to adhere the PVC film and the aluminum alloy plate through a film pasting machine. The sheet metal process comprises blanking, stamping, bending and angle forming.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
