Abstract
The invention discloses a rare-earth salt plating assistant solvent comprising the following components in molar ratio: 5-25% of ammonium chloride, 3-20% of zinc oxide, 0.5-2.0% of KBX and the balance of water. Hot dipping treatment is carried out on a base metal, so that the mechanical performance of the base metal can be enhanced, the oxidation resistance of the base metal is enhanced, and the base metal is more beautiful.
Description
Technical field
The present invention relates to a kind of rare-earth salts and help the plating solvent.
Background technology
At present, the coating for protection against corrosion of domestic matrix metal mainly comprises the different systems such as electro-galvanizing, galvanizing, aluminium, aluminium zinc, utilizes above-mentioned processing method, at the corrosion resistant monometallic coating of base metal surface plating one deck, in order to realize the protection to matrix metal.
Because the global atmosphere environmental quality worsens; in the air some corrosive gasess for example the content of some sour gas grow with each passing day; the corrosion aggravation of coating; monometallic coating; particularly have been difficult to satisfy the material protection requirement of modern industry in the resistance to corrosion of zinc coating and work-ing life, so, concerning aluminium zinc or aluminium-zinc alloy that erosion resistance is had relatively high expectations; exist the manufacturing cost height, product is difficult for the defectives such as realization.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of rare-earth salts and helps the plating solvent, by cooperating matrix metal is carried out the hot dip process processing, can strengthen the mechanical property of matrix metal, increases its oxidation-resistance, makes it more attractive in appearance.
For achieving the above object, the present invention adopts following technical scheme:
Propose a kind of rare-earth salts and help the plating solvent, component and corresponding component concentration following (calculating with mol ratio): ammonium chloride: 5%-25%; Zinc oxide: 3%-20%; KBX:0.5-2.0%; The water of surplus.
Preferably, described KBX is preferably KBB.
Preferably, component and corresponding component concentration following (calculating with mol ratio): ammonium chloride: 15%; Zinc oxide: 10%, KBB:1.5%; The water of surplus.
Wherein, KB is KBe among the KBX
2, X is acid ion, wherein, KBX is preferably boric acid beryllium potassium, i.e. and KBB, its chemical formula is KBe
2B
3O
7, X can also be sulfate ion etc.
After matrix metal is carried out pre-treatment, the rare-earth salts that the application of the invention proposes helps the plating solvent to cooperate, matrix metal is processed in hot dip process, when matrix metal is drawn in the alloy molten bath continuously automatically, be attached to the liquid alloy of base metal surface in process of setting, along with system temperature reduces, will constantly separate out with state of saturation as rare earth, the aluminium element of solute metal, preferential crystallization, and be enriched in the composite table facial mask that coating surface forms densification.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The rare-earth salts that proposes by the present invention helps the cooperation of plating solvent; after matrix metal carried out hot dip process and process, form one deck composite table facial mask in base metal surface, the composite table facial mask has the mechanical protection effect; simultaneously; the composite table facial mask has isolation effect, and the resistance that can increase simultaneously electrochemical system to be suppressing electrochemical process, so can slowing down corrosion; simultaneously; because coating surface state (such as refractive index) improves, and makes the matrix metal appearance luster beautiful, has ornamental preferably.
Embodiment

Embodiment 2
Propose a kind of rare-earth salts and help the plating solvent, component and corresponding component concentration following (calculating with mol ratio): ammonium chloride: 15%; Zinc oxide: 10%; KBB:1.5%; The water of surplus.Wherein, KBX is preferably boric acid beryllium potassium, i.e. KBB, and its chemical formula is KBe
2B
3O
7, X can also be sulfate ion etc.
The rare-earth salts that proposes by the present invention helps the cooperation of plating solvent; after matrix metal carried out hot dip process and process, form one deck composite table facial mask in base metal surface, the composite table facial mask has the mechanical protection effect; simultaneously; the composite table facial mask has isolation effect, and the resistance that can increase simultaneously electrochemical system to be suppressing electrochemical process, so can slowing down corrosion; simultaneously; because coating surface state (such as refractive index) improves, and makes the matrix metal appearance luster beautiful, has ornamental preferably.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
