Abstract
The invention relates to an environment-friendly chemical nickel plating brightener. The brightener comprises one or more than one of rare earth lanthanum or lanthanum sulfate, tellurium dioxide or tellurium sulfate, bismuth chloride or bismuth nitrate or bismuth sulfate, sodium molybdate or molybdenum dioxide. The brightener contains no harmful substances such as lead or cadmium, has no toxicity or harm, is environment-friendly, and meets the European Union RoHS standard. The brightener is an ideal effective brightener which can substitute harmful substances such as lead and cadmium in current chemical nickel plating, has a brightening effect exceeding that of lead or cadmium brighteners. The brightener can obtain a plating layer which is dense, bright, and good in bonding force and corrosion resistance, and is easy to be plated on metal surfaces of copper, iron, aluminum, etc.
Description
Technical field
The present invention relates to the process for treating surface of metallic substance, relate in particular to a kind of environmental friendly chemical plating nickel plating brightener and application.
Background technology
Chemical nickel plating is a kind of emerging process for treating surface, in the surface treatment industry, occupies very big proportion.Thereby be widely used in industrial sectors such as machinery, electronics, food, mould, metallurgy, petrochemical complex, pottery, waterpower, aerospace.On February 13rd, 2003; European Union's Official Journal has been announced " waste and old electric and electronic electrical equipment (WEEE) " instruction and " some objectionable impurities is used in restriction in the electric/electronic device " (RoHS) instruction; Regulation bans use of six kinds of objectionable impuritiess from producer's responsibility of 13 enforcement WEEE August in 2005 electrical equipment from July 1st, 2006: plumbous (Pb), cadmium (Cd), mercury (Hg), sexavalent chrome (Cr VI), PBBs (PBB), PBDE (PBDE).The at present domestic chemical nickel plating that also has objectionable impuritiess such as many enterprises are also leaded in use, cadmium.Though heavy metals such as lead, cadmium are usually used in glossing agent in chemical nickel plating, the coating brightness effect is very good really, all is deleterious to environment and people, does not meet the RoHS of European Union standard.Therefore, environmental friendly chemical plating nickel plating is just obtaining research more and more widely, and light is also wanted in environmental protection again.But the current environment protection brilliant agent that has can't reach the ideal brightness effect; Have plenty of the organism of employing and make brightening agent; The long storage time instability has throw out and separates out, and in up to 90 ℃ of pyritous chemical nickel plating working fluids, is prone to decompose, and has had a strong impact on the visual appearance of coating.Develop a kind of brightener for chemical nickel plating in this case, join the brightness that can not only improve chemical nickel plating coating in the chemical nickel plating working fluid, can also improve other performance of coating, as: erosion resistance, porosity, bonding force etc.The brightness effect of gained coating has reached or surmounted chemical nickel plating leaded, the cadmium brightening agent, and is environmentally friendly, nontoxic, meets the RoHS of European Union standard.
Summary of the invention
A kind of environmental friendly chemical plating nickel plating brightener.The brightness effect of gained coating has reached or surmounted chemical nickel plating leaded, the cadmium brightening agent, and is environmentally friendly, nontoxic, meets the RoHS of European Union standard.It is made up of one or more inorganic salt.The brightening agent major ingredient is one or more compositions of Rare Earth Lanthanum or lanthanum sulfat, tellurous oxide or sulfuric acid tellurium, bismuth chloride or Bismuth trinitrate or bismuth sulfate, Sodium orthomolybdate or molybdenum dioxide.This brightening agent content in the chemical nickel plating working fluid is 0.001-0.3g/L; Also can this brightening agent be made into liquid concentrator content is 1-300g/L, promptly in the chemical nickel plating working fluid, adds this concentrated type brightening agent 0.5-2ml/L.
Embodiment
1, proportioning components
2, brightening agent preparation
Rare Earth Lanthanum or lanthanum sulfat, tellurous oxide or sulfuric acid tellurium, bismuth chloride or Bismuth trinitrate or bismuth sulfate, Sodium orthomolybdate or molybdenum dioxide have been taken by weighing respectively by above-mentioned prescription numeric order respectively; Place container; The single deionized water dissolving of using, remix arrives together with 1: 1 dilute sulphuric acid heating for dissolving remix earlier in case of water-insoluble to together under evenly stirring then; Be diluted to volume requiredly again with deionized water, stir.Time spent only needs in the chemical nickel plating working fluid, to add this concentrated type brightening agent 0.5-2ml/L and gets final product.
3, the application in the chemical nickel plating working fluid
Above-mentioned 1 coating outward appearance is in same element task liquid, not add any brightening agent to carry out the plating gained, its 1 reference contrast as 2-16.
Single nickel salt 25g/L
Inferior sodium phosphate 30g/L
Trisodium citrate 10g/L
Lactic acid 20ml/L
DL-oxysuccinic acid 15g/L
Sodium acetate 12g/L
Potassium Iodate 10ppm
Brightening agent 0.5-2ml/L
90 ℃ of temperature
PH value 4.8-5.1
Tonburden 1dm2/L
The above instance has only been expressed several kinds of embodiments of the present invention, its describe comparatively concrete with in detail, but can not be stranded this and be interpreted as restriction claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Claims (3)
1. an environmental friendly chemical plating nickel plating brightener meets the RoHS of European Union standard.
