Abstract
The utility model discloses an aluminum-imitated stainless steel composite board, which comprises an aluminum-plastic board layer and an aluminum-imitated stainless steel coating, wherein the aluminum-plastic board layer consists of a bottom aluminum roll, a polymer film glue bonding layer, a plastic core layer, a polymer film glue bonding layer and a surface aluminum roll layer which are sequentially arranged from the inner layer to the outer side; the surface of the surface aluminum coil layer is coated with the aluminum-imitated stainless steel coating, the aluminum-imitated stainless steel coating is an FEVE resin paint layer, and the surface of the aluminum-imitated stainless steel coating is coated with a protective film layer. The utility model discloses can promote weatherability, anti chalking nature, anti color fading nature, the acid rain resistance and the corrosion resistance on composite sheet surface.
Description
Technical Field
The utility model relates to an imitative stainless steel composite sheet of aluminium for building board field.
Background
The aluminum-plastic composite board is a composite material which is formed by processing a coated aluminum plate subjected to chemical treatment as a surface layer material and polyethylene plastic as a core material on special aluminum-plastic board production equipment. The unique performance of the aluminum-plastic composite plate determines the wide application of the aluminum-plastic composite plate: it can be used for building external wall, curtain wall board, old building renovation, indoor wall and ceiling decoration, advertisement signboard, display rack and purification dust-proof engineering. Aluminum-plastic composite boards are widely used in China, and belong to a novel building decoration material. The surface color of the existing aluminum-plastic composite board is easy to peel, corrode and pulverize, and the surface appearance is easy to be influenced and deteriorated after long-term use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming prior art's not enough, provide an imitative stainless steel composite sheet of aluminium, it makes the composite sheet surface present stainless steel sheet metallic lustre nature, can promote weatherability, anti chalking, the anti-fading nature of composite sheet surface, the acid rain nature and the corrosion resistance simultaneously.
One technical scheme for achieving the above purpose is as follows: an aluminum-imitated stainless steel composite board comprises an aluminum-plastic board layer and an aluminum-imitated stainless steel coating,
the aluminum-plastic plate layer consists of a bottom aluminum coil, a high polymer film glue bonding layer, a plastic core layer, a high polymer film glue bonding layer and a surface aluminum coil layer which are sequentially arranged from the inner layer to the outer side;
the surface of the surface aluminum coil layer is coated with the aluminum-imitated stainless steel coating, the aluminum-imitated stainless steel coating is an FEVE resin paint layer, and the surface of the aluminum-imitated stainless steel coating is coated with a protective film layer.
Further, the surface of the aluminum coil layer has a corrugated structure produced by a wire drawing process.
Further, the aluminum-imitation stainless steel coating has a thickness of at least 16 μm.
The utility model discloses an imitative stainless steel composite sheet of aluminium, through the surface at the plastic-aluminum sheet layer, the imitative stainless steel coating of coating aluminium for this coating becomes the protective layer on plastic-aluminum sheet layer surface, and this protective layer can make the plastic-aluminum sheet surface produce the metallic luster of imitative corrosion resistant plate, makes the plastic-aluminum board have high weatherability, anti chalking nature, anti-fading nature, acid rain resistance and corrosion resistance simultaneously. The color change and color difference value delta E of the product is less than 5.0 under the condition of 10 years of outdoor use.
Drawings
Fig. 1 is a schematic structural view of the aluminum imitation stainless steel composite plate of the present invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1, the aluminum-imitation stainless steel composite board of the present invention includes an aluminum-plastic board layer and an aluminum-imitation stainless steel coating layer 2 coated on the surface of the aluminum-plastic board layer.
The aluminum-plastic plate layer is composed of a bottom aluminum coil 7, a polymer film glue bonding layer 6, a plastic core layer 5, a polymer film glue bonding layer 4 and a surface aluminum coil layer 3 which are sequentially arranged from the inner layer to the outer side.
The surface of the surface aluminum coil layer is coated with an aluminum imitation stainless steel coating 2 which is an FEVE resin paint layer. The coating is semitransparent, but the adhesion of the coating to an aluminum substrate is very firm, and the performance is excellent even in the outdoor long-term exposure.
In order to improve the adhesive force of the aluminum-imitation stainless steel coating 2, the surface aluminum coil layer 3 is subjected to surface wire drawing treatment, so that the surface has a corrugated structure generated through the wire drawing treatment. In order to ensure that the composite board has high weather resistance, chalking resistance, fading resistance, acid rain resistance and corrosion resistance which meet the requirements and have certain effects, the thickness of the aluminum-simulated stainless steel coating needs to be reduced. The aluminum-imitation stainless steel coating was tested to a thickness of at least 16 μm.
The surface of the aluminum-imitation stainless steel coating 2 is coated with a protective film layer 1, so that the external force resistance of the aluminum-imitation stainless steel coating 2 is improved as much as possible, and the surface of the aluminum-imitation stainless steel coating 2 is prevented from being damaged due to collision or friction.
It should be understood by those skilled in the art that the above embodiments are only used for illustrating the present invention, and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
