Abstract

The invention discloses a spraying process for handle powder wood grains on the surface of an aluminum material, which comprises the process steps of chromizing, spraying priming powder coating, procuring, spraying surface layer powder coating, wood grain brush forming, wood grain roll forming, and curing. A coating has thin-thread stripes and concavo-convex thick strips which are similar to fiber stripes of timber, thereby ensuring that the surface of the aluminum material has stronger wood-like effect, more three-dimensional touch good feeling, and better weather resistance. When the process is used to produce wood grain aluminum materials, the monthly yield of a production line is between 600 and 700 tons, and is 6 to 7 times of that of a production line of wood grain transfer; and the process is a full-automatic production process, which greatly saves human cost.

Description

A kind of spray coating process for handfeel powder wood grain on aluminum products surface
Technical field
What the present invention relates to is a kind of spray coating process for handfeel powder wood grain on aluminum products surface.
Background technology
Along with people's improving constantly to the ornament materials environmental consciousness, market is also increasing to the demand of surface grain aluminium, traditional wood grain aluminum profile extrusion technology mode is to have sprayed a kind of color powder manual woodgrained paper that sticks in back that is heating and curing, toast again the wood grain look is transferred to aluminium material surface, and then the manual woodgrained paper that tears, the wood grain aluminium material surface weather resisteant that this mode is made is poor, and mainly relies on manual production, and production capacity is very little.In order to solve these difficult problems, the needs design is a kind of can either to improve wood grain aluminium material surface weather resisteant, can realize the technology that the automation continuous batch is produced again.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of aluminium material surface treatment process, and a kind of aluminium material surface treatment process of this kind can make aluminium material surface have imitative wood effect, weatherability is relatively good, and can realize automatic batch production.
Technical solution problem of the present invention can be by taking following technical scheme:
A kind of aluminium material surface treatment process is characterized in that, comprises following processing step:
1) with the punching of aluminium one end, by this hole aluminium is hung on the chain then, makes aluminium follow chain and together advance;
2) aluminium material surface being carried out conventional chromaking handles;
3) make aluminium through drying oven, aluminium is carried out dewatered drying, make the aluminium material surface drying;
4) spray gun to aluminium material surface spraying bottom powdery paints with conventional escalator band, this kind coating is super weather-proof polyester solid powder paint, makes aluminium material surface form powder coating at the bottom of one deck;
5) make aluminium through curing oven, curing oven heats aluminium, makes end powder coating precuring;
6) the surperficial sprayed surface layer powdery paints of spray gun to end powder coating with conventional escalator band, form first surface powder coating, this kind coating is super weather-proof polyester solid powder paint, and its color is different with the color of bottom powdery paints;
7) under the uncured state of first surface powder coating, with conventional wood grain brush forming machine the surface of aluminium is whitewashed, make first surface powder coating have irregular filament striped;
8) with curing oven aluminium is heated, make the precuring of first surface powder coating;
9) the surperficial sprayed surface layer powdery paints of spray gun to first surface powder coating with conventional escalator band, form second surface powder coating, this kind coating is super weather-proof polyester solid powder paint, and its color is different with the color of bottom powdery paints;
10) under the uncured state of second surface powder coating, roll forming machine with conventional wood grain wood grain is rolled on the surface of aluminium, make second surface powder coating have concavo-convex irregular cord;
11) with curing oven aluminium is heated, end powder coating, first surface powder coating, second surface powder coating are solidified fully;
12) the finished product aluminium is transferred chain and is transported to the blanking platform, puts down the finished product workpiece.
Technical solution problem of the present invention can solve by taking following measure:
Described first surface powder coating not exclusively covers end powder coating.
In above-mentioned steps, the temperature during described precuring is set at 110-130 ℃.
Described temperature when solidifying fully is set at 185-200 ℃.
The present invention has following technique effect:
By above-mentioned technological process, make aluminium material surface form the powder wood grain coating, coating has filament striped and concavo-convex cord, and the fiber striped that is similar to timber is the same, makes aluminium material surface have more intense imitative wood effect.Its weather resisteant surpasses the ordinary powder spraying, more considerably beyond the transfer wood grain weather resisteant, aluminium material surface can not occur and fade and influence the problem of aluminium outward appearance.And coating surface is provided with concavo-convex cord, makes aluminium that touch feeling be arranged, and has strengthened the imitative wood effect of aluminium material surface.Each processing step to the processing of aluminium is all transported by chain, without manpower, can realize the automation of producing.600-700 tons of production line monthly outputs of this explained hereafter wood grain aluminium are 6-7 times an of production line of transfer wood grain, and are full-automatic production process, have saved human cost greatly.
The specific embodiment
Below in conjunction with specific embodiment the present invention is specifically described.
The aluminium material surface treatment process comprises following processing step:
1) with the punching of aluminium one end, by this hole aluminium is hung on the chain then, makes aluminium follow chain and together advance.
2) aluminium material surface being carried out conventional chromaking handles.It is in order to make aluminium material surface combine closelyr with coating that chromaking is handled, and it comprises such step, and sour oil removing, sour degreasing, washing, washing, chromaking, washing, pure water are washed.
3) make aluminium through drying oven, aluminium is carried out dewatered drying, at this moment, can set dry environment is 60-80 ℃, makes the aluminium material surface drying.
4) chain in powder room, the end, spray gun to aluminium material surface spraying bottom powdery paints with conventional escalator band with the aluminium band, and this kind coating is super weather-proof polyester solid powder paint, makes aluminium material surface form powder coating at the bottom of one deck.
5) make aluminium through curing oven, curing oven heats aluminium, and temperature is set at 110-130 ℃, makes end powder coating precuring.End powder coating is solidified substantially, be unlikely hurting end powder coating when making postorder wood grain brush mechanical molding.
6) chain with the aluminium band in surperficial powder room, the surperficial sprayed surface layer powdery paints of spray gun with the escalator band of routine to end powder coating, form first surface powder coating, this kind coating is super weather-proof polyester solid powder paint, and its color is different with the color of bottom powdery paints.Described first surface powder coating not exclusively covers end powder coating.
7) chain is brushed forming machine with the aluminium band in wood grain, under the uncured state of first surface powder coating, with conventional wood grain brush forming machine the surface of aluminium is whitewashed, and makes first surface powder coating have irregular filament striped.The filament striped is similar to the fiber striped of timber.
