The invention aims to solve the deficiencies in the prior art, and provides a mechanical zinc plating corrosion resisting process by nanotechnology which is high in precision and good in zinc plating effect and corrosion resisting effect. For a workpiece to be plated, the process comprises the following steps: degreasing, scouring, plate assisting, naturally drying, dip plating, hardening and quality test to obtain a needed plated plate. The coat of the plated part obtained is more uniform and compact, and the corrosion resisting service life of the coat is remarkably improved.
Description
Technical field
The present invention relates to a kind of zinc-plated technique, especially a kind of nanotechnology mechanical zinc-plating anticorrosion process.
Background technology
Because the hot dip galvanizing coating surface is comparatively coarse, accuracy requirement, the electroplating technology that can not reach tiny member can make member produce Hydrogen Brittleness Phenomena, and the anticorrosion with painting coating adhesion is very weak, the zinc-plated coating that exists of conventional mechanical is not fine and close, for improving the disadvantages associated of all kinds of coating technologies, nanotechnology mechanical zinc-plating technical matters becomes best solution route.
At present both at home and abroad conventional mechanical is zinc-plated has been widely used in all kinds of fastening pieces, tiny member, stamping parts, the castings such as screw, nail, pad and has forged part etc., the galvanized anticorrosive production of the precision component of the industry such as be particularly useful for machinery, electric power, building, automobile, add some points.Nanotechnology mechanical zinc-plating anti-corrosion technology is succeeded in developing the replacement conventional mechanical zinc-plated, and tool is of great significance.
Summary of the invention

The objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of precision high, zinc-plated effective and have a kind of nanotechnology mechanical zinc-plating anticorrosion process of anticorrosion ability.
In order to achieve the above object, the designed a kind of nanotechnology mechanical zinc-plating anticorrosion process of the present invention:
1) degreasing is immersed in workpiece to be plated in the degreasing solvent, and wherein skimming temp is 50～80 ℃, with all kinds of greasy dirts that remove workpiece surface to be plated, to reduce follow-up pickling time;
2) pickling at room temperature, is immersed in workpiece to be plated in the pickle solution, with the iron oxide layer that removes workpiece surface to be plated;
3) help plating, be covered in workpiece surface to be plated with liquid plating assistant agent thin film layer, wherein the plating assistant agent temperature is 50-70 ℃, helping the plating time is 1-2min, intercept contacting of oxygen in workpiece to be plated and the air, play simultaneously interfacial activity, improve the liquid alloy plating bath to the wettability of workpiece surface to be plated;
4) seasoning keeps the drying of workpiece surface to be plated;
5) immersion plating, zinc-plated staff scrapes clearly zinc liquid surface zinc gray, workpiece to be plated is immersed zinc liquid with 0～90 ° of angle of inclination, zinc liquid remains on 430～450 ℃, galvanizing time 40～60s takes out workpiece to be plated, strikes off the zinc gray of liquid level, prevent that zinc gray is bonded in workpiece surface to be plated, affects galvanizing quality; After workpiece to be plated hung out zinc liquid, zinc-plated staff will in time remove the zinc sagging on plating piece surface;
6) hardening will be cooled off in the plating piece immersion cooling tank behind the removing zinc liquid sagging, and cooled plating piece carries out seasoning to its surface;
7) quality test, the plating quality of detection plating piece.
Described degreasing solvent is comprised of sodium hydroxide, yellow soda ash and water, and wherein sodium hydrate content is 4～8%, and the content of yellow soda ash is 4～8%, and all the other are water.
The content of hydrochloric acid is 5～20% in the described pickle solution, and the content of iron protochloride is＜200g/L.
Described plating assistant agent comprises ammonium chloride, zinc chloride, rare earth plating assistant agent, hydrochloric acid and iron protochloride, and the mol ratio of described above material is 2:1:1:1:1.5.
Need washing after described degreasing and the pickling, thereby the degreasing solvent on the workpiece to be plated and pickle solution are removed
The present invention's resulting nanotechnology mechanical zinc-plating anticorrosion process and pot galvanize, electro-galvanizing and anticorrosion with painting are processed to compare has following advantage: 1) the nanotechnology mechanical zinc-plating can not produce the Hydrogen Brittleness Phenomena of electro-galvanizing, does not produce the annealing softening phenomenon of hot dip process yet; 2) the nanotechnology mechanical zinc-plating has good corrosion resistance nature, and its antiseptic property can be controlled galvanized layer thickness by the addition that changes nano zinc powder, and galvanized layer thickness control is very convenient; 3) simple, the easily operation of lower, the equipment of its production cost of nanotechnology mechanical zinc-plating process, floor space are little, power consumption less, strong adaptability, can realize again batch production simultaneously; 4) compare with existing conventional mechanical is zinc-plated, nanotechnology mechanical zinc-plating coating is even compact more, antiseptic power is higher, product life is long, nanotechnology mechanical galvanizing layer surface is difficult for polluting simultaneously, can keep self-cleaning, improve the range of application of its coating, thereby have wide market outlook and good economic benefit.
