A kind of imitation wood line aluminum veneer
Technical field
The utility model relates to a kind of aluminium plates of decorative coating, and in particular to a kind of imitation wood line aluminum veneer.
Background technique
Wooden building materials are the materials being commonly used in house decoration.Different wooden building materials, are played not in building decoration
Same effect.Currently on the market it is common to wood decorative material be mainly various wood-base fibre and particle panel materials, artificial decorative board, assembly and
Wood moulding timber floor etc..But wood materials exist meet water mutability, colour fading, it is not wear-resisting the defects of, service life is had a greatly reduced quality,
Therefore imitation wood line construction material can well solve the above problem.Most economical method is to coat one layer in building material surface
Imitation wood line coating realizes the decorative effect of grain pattern, to meet the needs of consumer is to building decoration.
Utility model content
The purpose of this utility model is that substituting existing wooden building materials, a kind of imitation wood line aluminum veneer is provided, is had
Mechanical strength more higher than wood materials, coating adhesion, resistance to that is more durable, and being obtained using the method for powder spray
Burn into is ageing-resistant etc. to be superior to lacquer spraying technique, and cost is also under the spray painting of same effect.
To achieve the goals above, the technical solution of the utility model is to design a kind of imitation wood line aluminum veneer, the aluminium list
Plate includes matrix aluminium, prime coat, top coat layer, transfer printing wood grain layer.Prime coat is equipped on described matrix aluminium, in the priming paint
Layer is equipped with top coat layer, and transfer printing wood grain layer is equipped on the top coat layer.The prime coat and top coat layer uses inorganic nano
The polyurethane powder coating of doped particles.
Particularly, described matrix aluminium includes aluminium mainboard, aluminium flanging, corner brace, reinforcing rib.
Particularly, the aluminium mainboard and aluminium flanging, carry out splicing of freezing, and are made into shelly-shaped matrix aluminium.
Particularly, the reinforcing rib is connected by bolt with aluminium mainboard.
Particularly, the corner brace is connected by pulling rivet with aluminium flanging.
Particularly, the transfer printing wood grain layer is pasted on finishing coat by transfer printing wood grain paper.
Advantages and beneficial effects of the utility model lie in that
1, the imitation wood line aluminum veneer carries out degreasing, polishing treatment first on the matrix aluminium of panel beating, then sharp
Various woodgrained papers are adsorbed on by the coating processing that priming paint and finishing coat are carried out with powder spray mode by thermal transfer printing process
Paint film handles surface, removes woodgrained paper, completes imitation wood line aluminum veneer preparation flow.The coating of preparation have stronger adhesive force,
Corrosion-resistant and ageing-resistant ability can keep the non-fading effect of wood pattern for a long time.
2, the coating process of the imitation wood line aluminum veneer, can be further used for galvanized sheet, steel plate, copper sheet, building material surface,
Play decoration, protection and beauty, manufacture craft is simple, easy to operate, low in cost.
3, the polyurethane powder coating that the technique of the imitation wood line aluminum veneer has used inorganic nano-particle to adulterate,
The coating have excellent corrosion-resistant, resistance to ag(e)ing, strong adhesive force, greatly prolong the service life up to 15 years with
On.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described further.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
A kind of imitation wood line aluminum veneer, the aluminium sheet include matrix aluminium, prime coat, top coat layer, transfer printing wood grain layer.Described
The polyurethane powder coating that prime coat and top coat layer use inorganic nano-particle to adulterate.
Described matrix aluminium includes aluminium mainboard, aluminium flanging, corner brace, aluminium reinforcing rib.
The aluminium mainboard and aluminium flanging, carries out splicing of freezing, and is made into shelly-shaped matrix aluminium.
The aluminium reinforcing rib is connected by bolt with aluminium mainboard.
The aluminium corner code is connected by pulling rivet with aluminium flanging.
The transfer printing wood grain layer is pasted on finishing coat by transfer printing wood grain paper.
Matrix aluminium of the utility model Jing Guo panel beating carries out spraying operation, and detailed process is as follows:
(1) workpiece surface pre-processes.Degreasing, polishing treatment are carried out in advance to workpiece surface;
(2) primer powder coating is sent into powder spraying apparatus, pretreating surface is sprayed using spray gun, is then carried out
High-temperature baking;
(3) finishing coat powdery paints is sent into powder spraying apparatus, surface is sprayed using spray gun, then carry out high temperature baking
It is roasting;
(4) by thermal transfer printing process, various woodgrained papers is adsorbed on top coat layer, need high temperature to add in printing process
Heat, imitation wood pattern automatic printing removes woodgrained paper on coating after heating 30 minutes, completes imitation wood line aluminum veneer preparation flow.
Powder spray technical requirements:
(1) surface of aluminum plate powder primer is at 50-60 μm or more, and finishing coat powder primer is at 60-90 μm or more, priming paint and finishing coat
The polyurethane powder coating adulterated using inorganic nano-particle;
(2) painting environments will keep completely, accomplishing environment temperature as far as possible not less than 12 DEG C, relative humidity is no more than 70 DEG C;
(3) electric field strength of powder spraying apparatus electrostatic field should control between 50-60KV, electric current stablize 100-120 μ A it
Between.
(4) high-temperature baking temperature is 200 ± 10 DEG C.
As shown in Figure 1, the utility model is a kind of imitation wood line aluminum veneer, which includes 1, matrix aluminium;2, prime coat;
3, top coat layer;4, transfer printing wood grain layer.
As shown in Fig. 2, the utility model needs to spray the matrix aluminium of panel beating, which includes 5,
Reinforcing rib;6, aluminium flanging;7, aluminium mainboard;8, corner brace.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement within the technical scope disclosed by the utility model should all cover the protection in the utility model
Within the scope of.Therefore, the protection scope of the utility model should be subject to the protection scope in claims.
