Abstract
The invention provides a magnesium material coloring method, which specifically comprises the steps that a clean magnesium material is suspended in a reaction kettle loaded with ultrapure water; the reaction kettle is thermally insulated for 1-15 hours in a drying oven at a temperature of 100-150 DEG C after being sealed and is then cooled to a normal temperature; and after the magnesium material is taken out and blown dryly, a colored magnesium material is obtained. Through using the method provided by the invention, magnesium and magnesium alloy materials in any shape, such as magnesium plates, magnesium rods and magnesium pipes can be colored and the colors are bright, varied and durable. The magnesium material processed by adopting the method provided by the invention has high decorativeness and is hopeful to be widely applied to multiple fields. The method provided by the invention does not contain any chemical reagents, and has the characteristics of low production cost, greenness, environmental protection, simple process, convenience in operation, easiness in large-scale industrial production, and the like.
Description
Technical field
The invention belongs to field of metal surface treatment technology, be specifically related to a kind of magnesium material colorize method.
Background technology
Magnesiumalloy is described as " 21 century tool development potentiality and the green engineering material of future ", has a wide range of applications in fields such as machinofacture, automobile making, aerospace, electronics, military affairs, communication, opticinstrument, computingmachines.Development along with society; People have higher requirement to the ornamental of material; Need the magnesium material to have certain color and luster in numerous Application Areass, like electronic product shell such as the notebook computer processed for magnesium alloy materials, mobile phone, extremely people's the favor of bright-coloured color and luster; And be used for the magnesium alloy materials of military aircraft or other defence product, then require the color and luster of material darker and not reflective.Therefore, adopt suitable surface treatment to give the magnesium material certain color and luster, it is significant for promotion and expansion Application of Magnesium promptly to prepare colored magnesium material.
The preparation method of existing colored magnesium material is that the colorize method of magnesium material is mainly after the anodic oxidation after electrolytic coloring (is the Chinese invention patent " two-step pigmenting method for green oxidation film layer on magnesium alloy surface " of ZL 200410067814.3 like the patent No.) or the anodic oxidation chemical staining (is the Chinese invention patent " colorize method of magnesium material and utilize the painted magnesium material shell of this method " of ZL 02142663.5 like the patent No.) again again.Utilize these methods can give the magnesium material certain color, color and luster is single, decorate properties is not strong but exist, and treatment process complicated, can't handle shortcomings such as complex-shaped workpiece, cost is high, the cycle is long, be subject to many limitations in application facet.Thereby the applicant adopts chemical conversion to handle mode and gives magnesium material decorate properties (patent No. is the Chinese invention patent " a kind of method of treating magnesium alloy work-piece surface " of ZL 200710078179.2) preferably at the conversion film of different color and lusters such as magnesium material surface preparation silver color, grey, golden yellow, purple, brown, brown, but this method treating processes relates to the use of more chemical reagent.Therefore, develop very necessity and urgent of more easy environmental type magnesium material colorize method.
Summary of the invention
To the deficiency that above-mentioned existing magnesium material dye technology exists, the purpose of this invention is to provide and a kind ofly do not use that chemical reagent, operation are simple, the colored magnesium material, preparation method of environmental protection.
The objective of the invention is to realize like this: the magnesium material of cleaning is suspended in the reaction kettle that ultrapure water is housed, and with insulation 1-15 hour in 100-150 ℃ baking oven of reaction kettle sealing back, cool to room temperature takes out the magnesium material, dries up then, promptly gets colored magnesium material.
Said ultrapure water satisfies Chinese experimental water national standard (GB/T6682-2008) one-level pure water standard, and adding volume of water is 1/3rd of reaction kettle cavity volume.
Said inner liner of reaction kettle is processed by polytetrafluoroethylmaterial material.
Said magnesium material comprises magnesium plate, magnesium rod, magnesium pipe different shape magnesium and magnesium alloy materials.
With respect to prior art, the present invention has following advantage:
1, the present invention's surface film of utilizing the magnesium material in high-temperature high-pressure steam, to generate dexterously mainly is made up of (hydrogen) oxide compound of magnesium and alloying element thereof, and the specific specific refractory power of these materials makes certain thickness surface film demonstrate specific color; Utilize the surface film of different thickness because interference of light effect meeting produces different colours, thereby give magnesium material fuchsin, grey violet, yellowish green, light green, ultramarine, yellow orange, golden yellow, pale yellow, warm brown, cold shades of colour such as brown, silvery white, silver grey through changing reaction times and temperature adjusting magnesium material surface film thickness.
2, the inventive method is used high, the impure few one-level pure water of purity and liner is stable as chemical property, the reaction kettle of the polytetrafluoroethylmaterial material of high temperature high voltage resistant; Guarantee the purity of high-temperature high-pressure steam in the still, thereby guaranteed the pure, even of magnesium wood color pool.
3, the inventive method does not contain any chemical reagent, has that production cost is low, environmental protection, technology are simple, easy to operate, be easy to characteristics such as large-scale industrial production.
4, can be different shape magnesium such as magnesium plate, magnesium rod, magnesium pipe and magnesium alloy materials through the inventive method carries out painted; And bright in luster, various, durable, the magnesium material that adopts the inventive method to handle have very high ornamental, be expected to obtain widespread use in a plurality of fields.
Embodiment
Embodiment and corresponding processing mode and magnesium material color see the following form.
Can find out from the foregoing description, utilize the inventive method to can be different shape magnesium such as magnesium plate, magnesium rod, magnesium pipe and magnesium alloy materials and carry out painted, and bright in luster, various; With respect to pure magnesium, other magnesium alloy materials because have trace alloying element existence, make the specific refractory power of magnesium material surface film have a little difference, so magnesium wood color pool also can be different.
The foregoing description sample carries out atmospheric exposure test basic no change of color more than 1 year in dry air, show its colour stable, durable.This shows, the magnesium material that adopts the inventive method to handle have very high ornamental, be expected to obtain widespread use in a plurality of fields.And the inventive method does not contain any chemical reagent, has that production cost is low, environmental protection, technology are simple, easy to operate, be easy to characteristics such as large-scale industrial production, and important promotional value is arranged.
In addition, the applicant discovers, utilizes the inventive method can also realize the painted of multiple metallic substance such as titanium or titanium alloy, zirconium and zirconium alloy, copper and copper alloy.With reference to the processing condition of the embodiment of the invention, can formulate the processing condition of different color sample to differing materials (multiple metallic substance such as magnesium material, magnesiumalloy, titanium alloy, zirconium and zirconium alloy, copper and copper alloy), carry out painted to various metallic substance.Therefore, other modifications of carrying out according to technical scheme of the present invention perhaps are equal to replacement, all should be encompassed in the middle of the claim scope of the present invention.
