Abstract
The invention discloses a manganese phosphide chrome passivant capable of ensuring passivation quality and facilitating environmental protection and a manufacturing method thereof. The manganese phosphide chrome passivant comprises the following raw materials in percentage by weight: 1.5-2.5% of phytic acid, 0.5-0.8% of tartaric acid, 0.4-0.8% of citric acid, 3-8% of sodium benzoate, 5-15% of sodium nitrite, 5-8% sodium carbonate, 5-15% of triethanolamine, 3-10% of polyethylene glycol, 4-7% of industrial spirit and the balance of water. The manufacturing method comprises the following steps: adding 1/2 of measured water to a reaction kettle; stirring the water at normal pressure and temperature and at a revolving speed of 200 turns/min; stirring the water while adding the measured phytic acid, the measured tartaric acid, the measured citric acid and the measured sodium benzoate in sequence; carrying out reaction on the mixture to dissolve the mixture before adding the measured industrial spirit; adding the mixture for 30min before adding the sodium nitrite, the sodium carbonate, the triethanolamine, the polyethylene glycol and the left 1/2 of the measured water; stirring the mixture for 60min until clear and transparent soluble liquid is obtained; and then carrying out sample survey, emptying and packaging.
Description
Technical field
The present invention relates to a kind of manganese-series phosphorized passivator and manufacture method, especially a kind of manganese-series phosphorized chrome-free tanning agent and manufacture method that both can guarantee the passivation quality and be beneficial to environmental protection.
Background technology
Phosphatization is the process that a kind of chemistry and electrochemical reaction form the phosphate chemical conversion film, and formed phosphate conversion film is referred to as phosphatize phosphate coat.Manganese-series phosphorized film thickness is big, hole is few, and phosphatize phosphate coat crystal grain is intensive shape, has been widely used in iron and steel parts, especially requires the iron and steel parts of wear resistant friction reducing.For Corrosion Protection and its antifriction lubricity of increase that improves phosphorization membrane, after manganese-series phosphorized, all tackle phosphatize phosphate coat and fill processing or sealing treatment, be referred to as Passivation Treatment.At present, used passivator all contains potassium bichromate or chromic anhydride basically, and these contain Cr
+ 6The passivating solution of ion can be particulate state, needle-like, the fine and close chromate film of dendritic crystal grain formation at manganese-series phosphorized film, can generate insoluble chromic acid ferrimanganic salt film at the hole position of manganese-series phosphorized film again simultaneously.But, contain Cr
+ 6The material of ion is highly toxic material, and environment is caused very big harm, and the serious threat mankind's life security is the process materials that National Environment Policy Act is kept under strict control.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of manganese-series phosphorized chrome-free tanning agent and manufacture method that both can guarantee the passivation quality and be beneficial to environmental protection to be provided.
