Abstract
The invention discloses a production method for an aluminum alloy frame. Aluminum alloy bars serve as main materials. The production method includes the steps of polishing, heating, hot pressing, aligning, saw cutting, aging, sand blasting chromium-free processing, end sealing, spraying, graving, coloring and hole sealing in sequence. The production method is characterized by further including the step that anodizing oxidation processing is carried out on a blank material before the coloring step; and an oxidation layer is formed on the surface of the blank material. By means of the production method for the aluminum alloy frame, orange-peel-shaped shrinkage, fat edges and the like of a produced aluminum profile are effectively avoided during spraying, and the ornamental value and the practicability are high.
Description
Technical field
The present invention relates to aluminium section bar manufacture field, particularly a kind of production method of aluminum alloy frame.
Background technology
Existing aluminium section bar production procedure comprises founding, extruding and colouring three steps, adopts aluminium section bar prepared by above-mentioned technique, easily occurring the phenomenon such as orange peel, fat edges, having had a strong impact on aesthetics and the practicality of product when spraying.
Summary of the invention
The technical problem that invention will solve is: the aluminium section bar of preparation, easily occurring the phenomenon such as orange peel, fat edges, having had a strong impact on aesthetics and the practicality of product when spraying
Technical solution of the present invention is: the production method disclosing a kind of aluminum alloy frame, the production method of described aluminum alloy frame take aluminium alloy bars as major ingredient, successively through polishing, heat, hot extrusion, straightening, sawing, timeliness, sandblasting chromium-free treatment, end socket, spraying, engraving, painted and sealing of hole step, it is characterized in that: also comprise before described painted step and anodized is carried out to blank, form layer of oxide layer in described blank surface.
Preferably, described oxidation processes is blank is put into the mixed solution of the sulfuric acid of 98% and the nitric acid of 98%, and the temperature of oxidation is 36 ~ 40 DEG C, and current density is 125A/dm
2.
Preferably, described aluminium alloy is through ramming oxidation processes.
Preferably, the thickness of described sprayed coating is 45 ~ 60 μm.
The present invention compared with prior art, has the following advantages:
Aluminium section bar of the present invention is subject to the effect of applying direct current under given condition of work, and surface forms the process of the erosion-resisting oxide-film of one deck, and its oxide-film obtained has water white transparency, and hole is many, and excellent adsorption is easy to the advantages such as dyeing.Time painted, dyestuff to be attracted on pore surface and to pore diffusion, accumulation, through sealing pores, dyestuff is fixed in hole.
Conventional painted method for sealing has hydration sealing of hole, inorganic salt solution sealing of hole, transparent organic coating sealing of hole.Concerning hot-spraying coating, sealing of hole is a necessary last handling process.In order to improve aluminum component quality and dye firm coloration, the fine pore of oxidation film layer must be closed after painted, the homogeneous non-porous become through Seal treatment rear surface, being formed fine and close oxide-film.Deposition of dye is again wiped in oxide-film, and avoids adsorb harmful components and contaminated or corrode in early days, thus improves the performance such as anti-pollution, against corrosion of anode oxide film.
The thickness of film of dusting can be conducive to forming obvious decorative pattern and larger decorative pattern between 45 ~ 60 μm, and the thin then decorative pattern of film is not obvious, and decorative pattern is also little, there will be the defects such as pit is show-through simultaneously.
The present invention's operation compared with conventional aluminum spraying section bar material technique is more loaded down with trivial details, but produce aluminium section bar and effectively avoid easily occur the phenomenon such as orange peel, fat edges when spraying, and sight, practicality are stronger.
