Description

PET-PBT decorative film composite color steel plate

Technical Field

The utility model belongs to the technical field of various steel sheet, specifically be a compound various steel sheet of PET-PBT decorative film.

Background

The color steel plate has various purposes, and is suitable for the building industry and the decoration industry as well as the shell of some equipment.

The decoration industry divide into indoor outdoor decoration, on outdoor wall, in order can be more pleasing to the eye, different wall paper of can laminating generally, but because wall paper is used for indoorly basically, and durability, water-fast and high temperature resistance are relatively poor, lead to outdoor will damage very fast, so, at present, most trade district can adopt the various steel sheet to replace wall paper.

However, at present, the integral structure of the beautiful and decorative color steel plate is divided into two layers of the substrate and the coating, so that although the color steel plate is more durable than wallpaper wall cloth, if the area with larger fluctuation of climate and temperature difference changes, the coating of the color steel plate is easy to turn outwards, the rust on the substrate is caused, and the decoration is reduced

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a compound various steel sheet of PET-PBT decorative film to solve the problem that how to improve various steel sheet in outdoor life.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a compound various steel sheet of PET-PBT decorative film, includes the plate body, the plate body includes basic unit, decorative layer, linkage layer, protective layer and skin, the basic unit coats and is stamped the decorative layer, it is fixed to glue through the adhesive linkage between basic unit and the decorative layer, be connected through the linkage layer between basic unit and the decorative layer and the protective layer, the coating has the skin on the protective layer, be provided with on the protective layer and bordure.

Preferably, the base layer is made of a hot galvanizing substrate material, and the thickness of the base layer is not more than 0.35 mm.

Preferably, the decorative layer is made of a plastic alloy material and has a thickness of not less than 100 micrometers.

Preferably, the tie layer and the adhesive layer are optically clear film adhesives.

Preferably, the protective layer is made of a polypropylene material.

Preferably, the outer layer is made of a polyvinylidene fluoride material.

Preferably, the thickness of the protective layer and the outer layer is not less than 300 μm.

Compared with the prior art, the beneficial effects of the utility model are that: the decorative layer and the base layer of the plastic alloy material can form a basic color steel plate structure, the durability and corrosion resistance of the whole plate can be improved through the protective layer connected with the connecting layer, and the service life of the whole color steel plate is greatly prolonged by matching with the effect of wind and sun protection of the outer layer.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1. a plate body; 11. a base layer; 12. a decorative layer; 13. a tie layer; 14. a protective layer; 141. Edge covering; 15. outer layer, 16 adhesive layer.

Detailed Description

Referring to fig. 1, the PET-PBT decorative film composite color steel plate comprises a plate body 1, wherein the plate body 1 comprises a base layer 11, a decorative layer 12, a joining layer 13, a protective layer 14 and an outer layer 15, the decorative layer 12 covers the base layer 11, the base layer 11 and the decorative layer 12 are fixed by adhesion through an adhesive layer 16, the base layer 11, the decorative layer 12 and the protective layer 14 are connected through the joining layer 13, the outer layer 15 covers the protective layer 14, and a covering edge 141 is arranged on the protective layer 14.

Referring to fig. 1, the base layer 11 is made of a hot-dip galvanized substrate material, and has a thickness of not more than 0.35 mm, so that the application range in the decoration industry is wide, and the practicability is strong.

Referring to fig. 1, the decoration layer 12 is made of plastic alloy material, and the thickness is not less than 100 μm, and the plastic alloy material is made of PBT/PET material, so that the decoration effect is good.

Referring to fig. 1, the bonding layer 13 and the adhesive layer 16 are optically transparent film adhesives, which can ensure the stability of the adhesion between the base layer 11 and the decoration layer 12 and between the decoration layer 12 and the protection layer 14.

Referring to fig. 1, the protective layer 14 is made of polypropylene material, and has a durable corrosion-resistant effect.

Referring to fig. 1, the outer layer 15 is made of polyvinylidene fluoride and has a function of protecting against wind and sunlight.

Referring to fig. 1, the thickness of the protective layer 14 and the outer layer 15 is not less than 300 μm, and is sufficient to ensure the protection effect.

The working principle of the scheme is as follows: the base layer 11 is made of a hot galvanizing substrate material, the thickness of the base layer is not more than 0.35 mm, the application range in the decoration industry is wide, the practicability is high, the decoration layer 12 is made of a plastic alloy material, the thickness of the decoration layer is not less than 100 microns, the plastic alloy material is made of a PBT/PET material, the heat insulation and attractive decoration effects are good, the base layer is adhered through an adhesion layer 16, the stability is high, a durable cavity is formed, the connection layer 13 is an optical transparent film adhesive, the adhesion stability of the decoration layer 12 and the protection layer 14 can be guaranteed, the protection layer 14 is made of a polypropylene material and has a durable corrosion-resistant effect, the wrapping edge 141 is of an integrated structure of the protection layer 14, the edge protection of the base layer 11 and the decoration layer 12 is achieved, water stain invasion from the edge is avoided, the condition that the edge material is reduced in adhesiveness and turned outwards due to solarization and drying is, the thickness of the protective layer 14 and the outer layer 15 is not less than 300 μm, and the thickness is sufficient to ensure the protective effect.
