Abstract
The invention relates to a zinc-plating brightener for metal parts, which is characterized in that the zinc-plating brightener mainly comprises zinc chloride, potassium chloride, boric acid, magnesium sulfate, lauryl sodium sulfate, phenolsulfonic acid, sodium benzoate, benzalacetone and the like. The zinc-plating brightener for metal parts has the characteristics that even plating performance is excellent, tank liquor is stable, the coating is even, the plating speed is fast, the sewage is easy to dispose, the coating processing is good, physical and mechanical properties are stable, and the like.
Description
Technical field
The present invention relates to a kind of metal parts zinc-plating brightener, belong to metal material surface electrochemical protection field.
Background technology
Zinc coating has been widely applied to the corrosion stability coating of ferrous materials, using more at automobile industry and electrical appliance industry circle is slightly acidic plating bath brightening agent, cyaniding plating bath brightening agent and zincic acid salt plating liquor brightening agent, their characteristic is as follows: compare with the weak acid plating bath, the bright property of basic zincic acid salt plating liquor or cyaniding plating bath and leveling property are poor, current efficiency lower (current efficiency of slightly acidic plating bath is more than 85%, and alkali plating solution is about 50%～70%); The covering power of basic zincic acid salt plating liquor or cyaniding plating bath is better than the slightly acidic plating bath, and service life of equipment is longer; The waste water of basic zincic acid salt plating liquor is easily processed, and is better than the cyaniding plating bath of severe toxicity; Compare with alkali plating solution, acidic bath is not cleaned ability, need carry out sufficient pre-treatment to plating piece; For the plating afterload that secondary processing produces, acidic bath is the most weak, easily produce the fragment defective that waits load to form owing to impacting, and the shock resistance of alkali plating solution is the strongest.Add up according to authoritative department; above-mentioned three kinds of galvanizing fluxs; wherein; the application of cyanide based solution accounts for 1/3; with regard to environment protection; use so widely cyanide based solution amazing; why cyanide based solution is widely used is because use the physical and mechanical properties of the zinc coating of this plating bath can obtain soft low-stress zinc coating from cyanide based solution; for bending; curling; the loads such as anti-extrusion and impact have very strong resistivity; and the tack of zinc coating; corrosion stability and ornamental all good; during to the zinc coating applying load, can avoid coming off; the defective such as expand or cracked.
Summary of the invention
Purpose of the present invention is exactly to be to solve and overcome above-mentioned defective, and a kind of excellent property of all plating is provided, and sewage is easily processed, the metal parts zinc-plating brightener that the coating processing technology is good and physical and mechanical properties is steady.
The present invention is achieved through the following technical solutions, it is characterized in that this metal parts zinc-plating brightener mainly by: zinc chloride, Repone K, boric acid, sal epsom, sodium lauryl sulphate, the acid of phenol semi-annular jade pendant, Sodium Benzoate, tensio-active agent, benzylideneacetone etc. form.
By containing in its every liter plating bath: zinc chloride 180～250g, Repone K 180～200g, boric acid 25～30g, sal epsom 10～20g, sodium lauryl sulphate 5.0～10g, phenol semi-annular jade pendant acid 5.0～10g, Sodium Benzoate 5～10g, tensio-active agent 150～200ml, benzylideneacetone 30～50g form.
Its tensio-active agent is hexadecyldimethyl benzyl ammonium benzyl ammonia chloride.
Specific embodiments
1, takes by weighing respectively hexadecyldimethyl benzyl ammonium benzyl ammonia chloride 185ml and boric acid 45g it is mixed, with its dissolving.
2, under the normal temperature state, take by weighing zinc chloride 180g, Repone K 200g, sal epsom 15g, sodium lauryl sulphate 5.0g, the acid of phenol semi-annular jade pendant 10g, phenylformic acid 5g, benzylideneacetone 35g, first above-mentioned medicine is used respectively a small amount of dissolved in distilled water, then mixed diluting is to required tank liquor amount.
3, will mix with the solution for preparing in 2 in 1, dilute with excess water by content in every liter, the solution pH value for preparing is 5～6.
Add the benzylideneacetone class in the brightening agent and can make the low current density district obtain bright coating, owing to there being tensio-active agent to exist, can improving zinc chloride and potassium chloride concentration thereby have in zinc-plated galvanic deposit.
