Abstract
The quick blackening liquid for cold spraying or chemical plating a black antirust film on iron or steel workpiece features the complex reaction of tannin with inorganic salt of Ni or Cu in acidic aqueous solution. The black film has adhesion and anticorrosion strength 5-6 times higher than those of existing similar products. Its advantages include simple technology, low cost and no environmental pollution.
Description
The present invention is applicable in the industrial circles such as machinery, electronics, automobile, motorcycle, metal standardized component that the antirust black film of the iron and steel parts of the various trades mark forms process for treating surface.The black anti-rust technology of present domestic above-mentioned iron and steel parts, eight or nine ten percent is to use deleterious black paint or high temperature soda boiling blackening craft, power consumption source big (electricity consumption was wanted 30-70 kilowatt-hour when general medium and small factory blackening craft went into operation), used chemical feedstocks is with serious pollution materials such as caustic soda, nitrite, potassium cyanide, the large equipments such as heating, air draft of still needing.From the late nineteen eighties, domestic priority several normal temperature occurred and has polluted little or nontoxic quick blackening liquid, up to now, the iron and steel parts after these product melanism, black film bonding force intensity does not also reach the intensity of old soda boiling black-labour skill, therefore by the person of adopting seldom.
Purpose of the present invention promptly is in order to overcome the above-mentioned deficiency of traditional blackening craft and known quick blackening liquid, researchs and develops that a kind of all-nontoxic is pollution-free, low temperature, blackening liquid fast.This blackening liquid can to big or small iron and steel parts band rust or rustless (must no grease) carry out cold being coated with (spray) or under low temperature environment (6-30 ℃ of scope) condition to there not being quick (2-5 minute) the electroless plated one-tenth black anti-rust film of oily rustless iron and steel parts.
The research and development mechanism of product of the present invention is: the tannin polymer reacts with inorganic molybdenum salt, nickel salt, mantoquita in the diluted acid aqueous solution, may generate the complex compound of many annulus.This complex compound can make various iron and steel parts under the reductive action of sulfuration hydrochlorate, even the surface of Al alloy parts, and (2-5 minute) forms black, the fine and close black anti-rust film of glaze fast in low temperature melanism pond (6-30 ℃).
The formula range of product of the present invention is as follows:
Material name formula range (grams per liter)
Inorganic nickel 1-5
Inorganic mantoquita 3-15
Inorganic molybdenum salt 10-30
Phosphoric acid zinc salt 15-40
Sulfo-sodium salt 3.5-16
Tannin 7-30
1000 milliliters in tap water
Regulate between the pH value 1-2 with industrial sulphuric acid.
Above raw material all adopts the technical pure level.
Accompanying drawing 1 and accompanying drawing 2 are that the physicochemical property of the present invention and domestic like product compares.
In the accompanying drawing 1: A-product of the present invention, the soda boiling of B-high temperature is black, C-other types blackening liquid.
In the accompanying drawing 2: A '-product of the present invention, the B '-quick blackening liquid of SX-891 normal temperature, C '-other types normal temperature blackening liquid, D '-high temperature soda boiling is black.
The used test method of accompanying drawing is undertaken by JB2836-80, JB2111-77 required standard fully.
Find out that from accompanying drawing 1,2 physicochemical property of the present invention is higher than domestic conventional high-temperature far away and boils black and each normal temperature type blackening liquid. Workpiece takes out from blackening liquid of the present invention, needn't saponification soak passivation behind the natural air drying to percent 90, and directly the immersion oil sealing gets final product. When the floating thing in the dried rear surface of surface of the work is too much, after can in swift running water, washing it, vertical Namely dropped in the alkaline sodium chromate liquid passivation 1-2 minute, take out natural air drying, storage period has been grown the floating thing rust of no longer appearance in air like this, when idol has the ecru rust to occur, dab namely to fall with cloth, when serious such as ecru, again workpiece being entered to soak in the former blackening liquid several seconds ecru rust is full Ex-all, after the taking-up, slightly stop the several seconds and just enter oil sealing and close namely appropriate.
The complex compound of the used tannin of the present invention and molybdenum, mantoquita reaction is rolled up entirely by international joint inspection CA(chemical abstracts 67-93), international chemical industry pricks the full volume of note 67-93 and all finds at the end. Hand has been examined the full volume of U.S. METAL FINISING 1988-1993 and Japan version " sufacing " 1990-1993 rolls up entirely again, also hand has been examined in the world three authoritative three chemistry encyclopedias simultaneously: " KIRK-OTHMER Encyiopedia of Chemical Tachnoligy ", " ULLman ' s Eneylopedia of lmdurtrial Chemistry ", " Encylopedia of polymer Seience and technology " also retrieved the domestic and international patent of 1988-1992 and domestic periodical " sufacing ", " metal corrosion and protection " all do not find the tannin molybdenum, copper complex is used for the correlation technique report of blackening of iron and steel.
The used industrial chemicals of the present invention all is nontoxic free from environmental pollution, and the manufacturing of product uses technology simple, need not any heating energy source and large equipment investment, in integrated mill, namely applicable the transformation of original high-temperature boiling black-labour skill simplified equipment, some medium and small producers are as long as there is a 10-15 rice2The workshop, room, one 3 * 1 meters2Workbench, some Plastic Drum basins can carry out the melanism work production.
This product is if extensively drop into society, then energy savings, improve the saving with maintenance cost of subduing of environment and these relevant devices, shorten man-hour and improve work efficiency, all advantages such as cost will obtain great economic benefit and social benefit.
