Description
Technical field
The present invention relates to field of mechanical technique, and in particular to a kind of aluminium base Water based metal micro-powder coating and a kind of aluminium base water system
The preparation process of microparticle metal coating.
Background technique
Handling the common method of one kind to Metal surface anti-corrosion both at home and abroad at present is electrogalvanizing, but the pollution of this method is tight
The phenomenon that weight, energy consumption are big, and electroplating process is also easy to produce hydrogen embrittlement, cause material embrittlement and fracture.Zinc coat is using temperature by passivating film
The limitation of aging temperature, can only be used below at 100 DEG C, there is biggish limitation, is not suitable for using under rugged environment.Electricity
Zinc-plated anticorrosion principle is mainly anode loss protection, i.e., zinc coat resistance to corrosion is directly proportional to the thickness of coating, usually
In the case of the standard thickness of electro-galvanized layer be about 8-15um, and the thickness of electro-galvanized layer is about 5-10um in actual production, thus
Its resistance to corrosion is poor.The corrosion resistance of Hot-dip Galvanizing Coating can be much higher than electro-galvanized layer, but its energy consumption and pollution are even more serious, and
Galvanizing thicknesses of layers is big, low precision, is not suitable for precision component and fastener.In recent years, since the regulation of environmental protection is strong
Change, traditional process of surface treatment, such as hot-dip and plating all because technical process generates certain pollution, it is many country and ground
Area is restricted.The process of surface treatment of steel material expects the birth of free of contamination " green process for treating surface ".
Summary of the invention
That the problem to be solved by the invention is to provide a kind of appearance of coat is uniform and smooth, with compared with high-decoration and have compared with
The aluminium base Water based metal micro-powder coating and its preparation process of good corrosion resistance and heat resistance.
To achieve the goals above, the technical scheme adopted by the invention is as follows: a kind of aluminium base Water based metal micro-powder coating by with
The raw material of lower parts by weight forms:

50-80 parts of water.
Preferably, the aluminium base Water based metal micro-powder coating is made of the raw material of following parts by weight:
3 parts of zinc powder,
4 parts of aluminium powder,
18 parts of chromic anhydride aqueous solution,
12 parts of compound phosphoric acid dihydric salt,
15 parts of methylcellulose,
4 parts of sodium fluoride,
55 parts of water.
Preferably, the preparation process of the aluminium base Water based metal micro-powder coating includes the following steps:
(1) part is put into the hydrochloric acid of 1g/1 and impregnates 2-3min, to remove the grease, floating embroidery and oxidation of workpiece surface
Object；
(2) raw material of aluminium base Water based metal micro-powder coating is added to the container according to the ratio, stirs 1-2min, until stirring is equal
It is even；
(3) part is put into after impregnating 0.8-1.5min in the solution of step (2) and is taken out；
(4) part rinses 2-3min with clear water；
(5) part preheats 10-15min, and temperature is controlled at 75-85 DEG C；
(6) part, which is put into dryer, toasts 25-35min, and temperature is controlled at 280-320 DEG C；
(7) natural cooling.
Beneficial effects of the present invention: the present invention is by by zinc powder, aluminium powder, chromic anhydride aqueous solution, compound phosphoric acid dihydric salt, methyl
The raw materials such as cellulose and sodium fluoride are mixed with by weight ratio, and the aluminium base Water based metal micro-powder coating prepared has outer
See it is uniform and smooth, have the advantages that compared with high-decoration and there is preferable corrosion resistance and heat resistance, and coating process is simple and convenient,
Save human cost.
