Abstract
The present invention belongs to the technical field of surface chemistry, which particularly relates to an ordinary temperature phosphatizing liquid for phosphatizing steel surfaces. The present invention is suitable to be used in large-scale equipment such as automobiles, etc., in the extreme environment. The ordinary temperature phosphatizing liquid of the present invention is composed of the following substances according to weight percentage: 2.0 to 4.0% of phosphoric acid, 0.4 to 0.6% of zinc oxide, 0.5 to 1.5% of zinc nitrate, 3.0 to 5.0% of nickel nitrate, 2.0 to 4.0% of manganous nitrate, 0.2 to 1.0% of sodium borofluorate, 2.0 to 3.0% of sodium chlorate, 0.5 to 2.0% of citric acid and softened water for the rest. The ordinary temperature phosphatizing liquid of the present invention has the advantages of high stability, long film forming time, large film forming strength and strong corrosion resistance.
Description
(1) technical field
The invention belongs to the technical field of surface chemistry, particularly a kind of steel surface is carried out parkerized normal-temperature phosphorizing liquid.
(2) background technology
Steel surface is carried out bonderizing, and the phosphatization liquid use temperature height that tradition is used, power consumption are greatly, the time is long, cost is high.For resembling large-scale workpieces such as automobile chassis and component,, concerning some medium-sized and small enterprises, relatively more difficult especially if carry out the medium and high temperature phosphatization.Disclose 2 kinds of black liquid and technologies thereof of carrying out step-by-step processing as Chinese patent CN1076225, CN1077757, though step-by-step processing can obtain the black phosphating film, film forming is more loose, and technological process is long, the cost height.Reach its technology altogether as the open phosphatization liquid of Chinese patent CN1231705, its use temperature is the 15-75 degree, and cost is than higher, and film formation time is long, and film forming is loose, and solidity to corrosion is poor, is not suitable for resembling automobile chassis and is operated in the more abominable workpiece of environment like this.
(3) summary of the invention
The object of the present invention is to provide a kind of phosphatization liquid good stability, long, the one-tenth normal-temperature phosphorizing liquid that film toughness is big, solidity to corrosion is strong of film formation time.
The object of the present invention is achieved like this:
Normal-temperature phosphorizing liquid of the present invention is made up of following substances in percentage by weight,
Phosphoric acid 2.0-4.0%
Zinc oxide 0.4-0.6%
Zinc nitrate 0.5-1.5%
Nickelous nitrate 3.0-5.0%
Manganous nitrate 2.0-4.0%
Boron fluoric acid sodium 0.2-1.0%
Sodium chlorate 2.0-3.0%
Citric acid 0.5-2.0%
The softening water surplus
Normal-temperature phosphorizing liquid of the present invention owing to added compound accelerator and composite passivant---nickelous nitrate, manganous nitrate, boron fluoric acid sodium and sodium chlorate, make phosphatize phosphate coat and workpiece to combine speed fast, in conjunction with more firm.Phosphatization liquid phosphatization is speeded up, and make film forming and intensity big.
The production method of normal-temperature phosphorizing liquid of the present invention, at first that zinc oxide is moistening with mixes with small amount of water, add phosphoric acid, after the dissolving fully, add other raw material again, stirring gets final product.
Normal-temperature phosphorizing liquid of the present invention, its using method is also fairly simple, and processed workpiece earlier will be through technologies such as pre-treatment, degreasing, table accent, make workpiece surface not have oil, rustless and foul, adopt the construction of dipping or spraying method, handled at normal temperatures 3-5 minute, need not heating, save the energy, easy to operate.Processed workpiece film forming densification, even, continuous, film formation time is short, becomes film toughness big, can satisfy the requirement of workpiece such as automobile.
Therefore, normal-temperature phosphorizing liquid of the present invention has phosphatization liquid good stability, long, the one-tenth advantage that film toughness is big, solidity to corrosion is strong of film formation time.
