Abstract
The invention discloses a phosphating additive before tinting of metallic surface in surface chemical technical domain, which comprises the following steps: allocating with mass ratio as 3-7 phosphoric acid, 2-8 zinc dihydrogenphosphate, 1-6 zinc nitrate, 1-3 nickel nitrate, 0. 1-3 sodium fluoroborate, 0. 5-4 sodium chlorate, 1-3 citric acid, 1-4 sodium nitrite and 50-65 soften water; getting the product. This invention can be used to proceed phosphate treatment for metallic surface.
Description
Technical field:
The invention belongs to the technical field of surface chemistry, particularly a kind of to carrying out parkerized method before the steel surface japanning.
Background technology
Phosphating agent before the steel surface japanning.At present, domestic many steel product processing enterprise, before carrying out steel product processing japanning, simple oil removing, processing of rust removing are only made in the metallic surface, do not do careful chemical process, for hidden danger has been buried in ferrous materials use from now on, i.e. use through half a year to one year just begins to occur corrosion phenomena, has seriously influenced the work-ing life of steel.There is the use temperature height in more existing phosphorization technologies, and the tank liquor instability is prone to the antiseptic property that sediment has reduced phosphatize phosphate coat.
The content of invention
The purpose of this invention is to provide a kind of preceding phosphating agent of finish coatings that is used for ferrous materials, ferrous materials carries out chemical treatment in the phosphate solution that contains manganese, iron, zinc, make the metallic surface generate the method that one deck is insoluble in the phosphate coating of water.Phosphatize phosphate coat is mainly as the bottom of coating, and is firm with matrix bond, has good adsorption, solidity to corrosion and higher electrical insulating property etc.Improved the work-ing life of ferrous materials greatly, reduced the corrosion of ferrous materials, can save a large amount of steel for country.
Preceding its composition of phosphating agent of finish coatings that is used for ferrous materials of the present invention comprises: phosphoric acid, primary zinc phosphate, the ratio of weight and number of each component is: phosphoric acid 3-7, primary zinc phosphate 2-8, zinc nitrate 1-6, nickelous nitrate 1-3, boron fluoric acid sodium 0.1-3, sodium chlorate 0.5-4, citric acid 1-3, Sodium Nitrite 1-4, softening water 50-65.
The invention has the advantages that:
1, can use at normal temperatures.
Use down for 15～35 ℃ at normal temperature, do not need the energy.Physical environment there is good protection.
2, do not need heating installation.Owing to do not need the energy, saved heating installation, reduced facility investment.
3, save energy.Do not need heating in this process of producing product and in the use, so saved the energy.
4, be easy to produce.The phosphating agent that the present invention narrated is a compatibility type product, does not need to synthesize, and technology is easy, has saved main equipment and factory building, easy handling.
5, phosphating agent good stability, sediment are few.Common phosphating agent instability easily produces precipitation, is difficult to safeguard.
6, become film toughness big, the throw out that undopes in the phosphatize phosphate coat that is generated, the fine and closely woven micropore of rete is even, is better than other common phosphatize phosphate coat.
7, solidity to corrosion is strong, and the fine and closely woven micropore of rete is even, can obtain to be better than the erosion resistance of common phosphatize phosphate coat.
8, because phosphorization membrane is that fine and closely woven microvoid structure and surface daub on a wall material have better bonding properties
