The wood grain aluminium sheet
Technical field
The utility model relates to the field of ornament materials, especially a kind of wood grain aluminium sheet.
Background technology
Aluminiumplastic composite panel is prone to because of it has that processing, material are light, surfacing, be easy to processing, be easy to install the lamp characteristics, and is widely used as the fields such as decoration, billboard decoration, furniture, handicraft of indoor and outdoor wall.Conventional at present Aluminiumplastic composite panel, its form is single, and antiseptic power is poor, application life short.Development along with society; The sheet material that color is single does not have floral designs, has satisfied not the pursuits of people to fashion; Have plenty of on aluminium base; Cover that one deck has the PVC film of floral designs or with printing ink transfer printing one deck floral designs, but its pattern is prone to come off, embrittlement, weatherability is poor, texture is fuzzy, figure is false, outdoor application again.
The utility model content
The technical problem that the utility model will solve is: in order to overcome the problem that exists in above-mentioned, a kind of corrosion-resistant, long service life is provided and can satisfies the wood grain aluminium sheet of people's demand.
The utility model solves the technical scheme that its technical problem adopted: a kind of wood grain aluminium sheet; Comprise the aluminium substrate; Described aluminium substrate surface is coated with passivation film; Be coated with prime coat on the described passivation film, described prime coat is provided with the baking vanish layer, and described baking vanish layer is provided with the transparent protecting paint layer.
In order to satisfy the demand of people to fashion, described baking vanish laminar surface is grained.
The beneficial effect of the utility model is: the wood grain aluminium sheet of the utility model, adopt grain pattern as baking vanish layer, appearance looks elegant; Reduced the cold ice-cold sense of metal, tight with natural combination, can satisfy people's quality and beautiful demand; Through high-temperature baking, make its pattern difficult drop-off.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. aluminium substrates among the figure, 2. passivation film, 3. prime coat, 4. baking vanish layer, 5. transparent protecting paint layer.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Wood grain aluminium sheet as shown in Figure 1 comprises aluminium substrate 1, and aluminium substrate 1 surfaces coated is covered with passivation film 2, is coated with prime coat 3 on the passivation film 2, and prime coat 3 is provided with the surface and is graininess baking vanish layer 4, and baking vanish layer 4 is provided with transparent protecting paint layer 5.
The manufacture craft of the wood grain aluminium sheet of the utility model: at first allocated priming paint, baking vanish, finish paint, priming paint, baking vanish, finish paint that allotment is good are sprayed on the aluminium substrate 1 successively, and wherein the operation air pressure of priming paint spray gun is controlled to be 0.1MPa; The operation air pressure of baking vanish spray gun all is controlled to be 0.04MPa; The operation air pressure of finish paint spray gun is controlled to be 0.15MPa, and the equal time of priming paint levelling is 10min, and the baking vanish flow time is 7min; The nozzle bore that the baking vanish automatic air spills a rifle is 2.0mm; The equal time 15min of finish paint levelling, then with aluminium substrate 1 baking and curing, last pad pasting, packing, warehouse-in.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the manual, must confirm its technical scope according to the claim scope.
