Description
Technical field
The invention belongs to field of metal surface treatment technology, concretely relates to a kind of steel fluxing agent.
Background technology
At present, countries in the world carry out batch galvanizing using solvent method.Preferable dip galvanized is obtained, product
Pre-treatment is extremely important.Different from other steel surface application techniques, being removed before steel piece galvanizing by dipping needs alkali cleaning oil removing, pickling
Derusting is outer, and also one of solvent helps plating.Plating is helped as a procedure important in galvanizing by dipping pre-treatment, not only direct shadow
Quality of coating is rung, also has larger shadow to zinc consumption cost.Conventional quickening liquid is the mixed solution of zinc chloride and ammonium chloride, zinc chloride
Main ironware surface when acting to prevent hot dip by secondary oxidation, while can in fusing profit of the increase zinc liquid to ironware surface
Moist, ammonium chloride decomposes when contacting zinc liquid, discharges hydrogen chloride gas and ammonia, can activate ironware surface, purifying liquid zinc and
The oxide on zinc liquid surface is removed, although ammonium chloride can discharge hydrogen chloride gas and ammonia, the environment destroyed in workshop,
Its production cost is low, easily controllable, and it is still the existing main flow for helping plating.
But plating piece after the processing of existing zinc ammonium chloride fluxing agent it is zinc-plated after surface zinc coat often uneven thickness, light
Cleanliness is not high, and plating piece has plating leakage, and the zinc-plated total quality for being is not high.
The content of the invention
It is an object of the invention to provide a kind of steel fluxing agent, and it can reduce the burst size of hydrogen chloride and ammonia
At the same time it can also improve the surface quality of plating piece coating, make galvanized layer thickness uniform, it is highly polished, save zinc material.
In order to solve the above technical problems, the object of the present invention is achieved like this：A kind of steel fluxing agent, its feature exist
In：The composition and its percentage by weight of the fluxing agent include zinc chloride 5-10%, ammonium chloride 15-30%, sodium fluoride 0.1~
2%th, fluorosurfactant 0.05-0.2%, stannous oxide 0.1-1% and rare earth-iron-boron 0.5~2%, surplus are water；
The rare earth-iron-boron includes at least one of lanthanum chloride, cerium chloride, lanthanum-cerium chloride and zirconium oxychloride.
On the basis of such scheme and as the preferred scheme of such scheme：The composition and its weight hundred of the fluxing agent
Point than include zinc chloride 8%, ammonium chloride 20%, sodium fluoride 1%, fluorosurfactant 0.1%, stannous oxide 0.5% and
Rare earth-iron-boron 1.5%, surplus are water.
The accounting of ammonium chloride decreases relative to accounting of the prior art, so as to laugh at hydrogen chloride gas and ammonia
Burst size.
Sodium fluoride heat endurance is good, plating piece surface can be protected not oxidized, and can improve between steel and zinc liquid
Infiltrating.
Fluorosurfactant is a kind of outstanding wetting agent and levelling agent, can significantly improve zinc coat the uniformity and
Flatness.
Stannous oxide can accelerate coming off for plating piece surface fluxing agent film, accelerate zinc-plated speed.
The addition of rare earth-iron-boron can be accelerated zinc liquid and the reaction on plating piece surface, made zinc liquid quick with activated metal surface
With plating piece surface carry out metallurgical binding；Reduce the viscosity on zinc liquid top layer so that coating surface is smooth；Enter coating microstructure
Step refining and coated metal is set further to purify, so as to improve the bond strength of coating and plating piece.
On the basis of such scheme and as the preferred scheme of such scheme：The application side of described steel fluxing agent
Method comprises the following steps：
S1：It will be rinsed after degreasing, pickling process processing with clear water；
S2：Plating piece is immersed in quickening liquid, soak time 2-5min, quickening liquid temperature is 70-80 DEG C, pH value 3-5；
S3：The step S2 steel and iron parts helped after plating are dried, dried to the steel and iron parts surface non-water flow vestige.
On the basis of such scheme and as the preferred scheme of such scheme：The step S2 also includes shaking plating piece
Step.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：The accounting of existing zinc chloride ammonia is carried out
Adjust and simultaneously the composition of quickening liquid is improved, allow it while the burst size of hydrogen chloride and ammonia is reduced, can be with
The surface quality of plating piece coating is improved, makes galvanized layer thickness uniform, it is highly polished, save zinc material.
