Description
Technical field
The present invention relates to technical field of surface, particularly relate to a kind of step Unoiling, rust-cleaning and parkerizing technique of iron and steel parts.
Background technology
The stable phosphatize phosphate coat of a number of plies micron thickness can be formed in metallic surface after metal and phosphoric acid or phosphate chemical react; protection is provided to metallic matrix by this phosphatize phosphate coat; namely erosion resistance and the wear resistance of metal is improved; and phosphatize phosphate coat also can stand the short time high temperature baking reaching more than 400 DEG C; and the sticking power of coating metal surfaces layer can be improved ideally, in metal cold complete processing, play the effect of antifriction lubrication etc.
Publication number CN1283710A discloses one " Phosphating Solution of iron and steel cold deformation processing and phosphating process thereof ", publication number CN1115794A discloses " a kind of iron and steel derusting and phosphorating liquid ", publication number CN101117709A discloses " a kind of nickeliferous steel iron phosphatising liquid and method for bonderizing thereof ", and publication number CN101328583A discloses " a kind of manganese phosphating liquor and its preparation method and application ".
But there is following logical fraud in the Phosphating Solution exemplified above: one is owing to directly using nitric acid in formula, therefore there is yellow smog and pollute in process for preparation, not only have the environment that preparation is on-the-spot, and there is the anxiety undermining operator's health; Two is be unfavorable for save energy because when adopt the Phosphating Solution of above-mentioned teach literature when carrying out bonderizing to metal Heating temperature usually more than 85 DEG C, thus the energy-saving economic spirits of saving type advocated with the current whole society.
Publication number CN1037936A discloses a kind of Phosphating Solution and preparation method, this Phosphating Solution is made up of nitrocalcite, zinc phosphate, nickelous nitrate, Jing Ti/Bao Pian COBALT NITRATE CRYSTALS/FLAKES, nitric acid tin, citric acid, tartrate, EDTA, Surfactant OP and water, have that raw material is inexpensive easily to be got, the advantages such as preparation is convenient, antirust ability is strong, but need in the Phosphating Treatment Process before iron and steel parts application to heat to 65 ~ 70 DEG C, form residue, be 1 ~ 15 gram/meter with iron and steel parts unit surface film quality after the method bonderizing simultaneously
2, and in fact before application iron and steel parts bonderizing require that film quality is less than 5 grams/meter
2, otherwise the paint film after iron and steel parts application there will be peeling phenomenon.
Publication number CN85100689A " a kind of derusting phosphating liquor ", CN1030947A " Unoiling, rust-cleaning and parkerizing liquid ", CN1038470A " surface treatment agent for iron and steel-a novel inhibitor and derusting " is by phosphoric acid, tertiary sodium phosphate, chromic acid, the compositions such as tensio-active agent, such Phosphating Solution has rust cleaning, degreasing and rust removal or derusting rust-proofing advantage, iron and steel parts phosphatization processes under 30-65 DEG C of condition, iron and steel parts after process is without washing, at ventilation airing, continue nature phosphatization, though this Phosphating Solution solves the problem reducing residue, but the bonderizing before iron and steel parts application still needs to heat, and through natural airing phosphatization, phosphatize phosphate coat formation time is longer, in the larger situation of ambient moisture, iron and steel parts easily produces the problem that brightness reversion gets rusty, in iron and steel parts parkerizing process, Phosphating Solution change of component is larger, safeguard that Phosphating Solution concentration of component is more difficult.
Summary of the invention
The object of the invention is to the step Unoiling, rust-cleaning and parkerizing technique proposing a kind of iron and steel parts, the Phosphating Solution that this technique adopts is by adjustment component, it is made to carry out bonderizing at normal temperatures, this Phosphating Solution possesses degreasing and rust removal function simultaneously, therefore, degreasing and rust removal and phosphatization one step can be completed, save operation.
For reaching this object, the present invention by the following technical solutions:
An one step Unoiling, rust-cleaning and parkerizing technique of iron and steel parts, consisting of of the Phosphating Solution that this technique adopts: 85% phosphatase 11 65-175g/L, biphosphate nickel 22-28g/L, primary zinc phosphate 14-18g/L, biphosphate cobalt 6-8g/L, sodium chlorate 6-8g/L, m-nitrobenzene sodium sulfonate 2-4g/L, yellow prussiate of potash 2-4g/L, ammonium molybdate 1-3g/L, thiocarbamide 2-4g/L, tartrate 11-15g/L, OP-106-10g/L, surplus is water; Described phosphating process is: above-mentioned component is mixed with Phosphating Solution, make its free acidity be 14-20, total acidity is 200-240, makes the temperature of Phosphating Solution remain on 15-35 DEG C, then iron and steel parts is put into Phosphating Solution and process 25-35 minute, dry in ventilation after then taking out.
The present invention has following beneficial effect:
1) Phosphating Solution that adopts of present invention process is by adjustment to component, such that phosphatization temperature is minimum can be reduced to 15 DEG C, all can carry out normal temperature phosphating throughout the year, and without the need to heating, therefore save the energy, save operation in the workshop of therefore most area.
2) iron and steel parts is placed in same tank liquor to process 25-35 minute and get final product a step and completes oil removing, rust cleaning, bonderizing by the present invention, and operation sequence is few, greatly reduces investment and the working area of equipment, and is easy to realize mechanize and automatization.
3) iron and steel parts is after Phosphating Solution process of the present invention, and the phosphatize phosphate coat crystallization even compact formed, marshalling, its film focuses on 4-30g/m
2controlled, corrosion stability is excellent, strong to coating bonding force; Use procedure solution property is stablized, few with rear sediment, is easy to administer and regeneration.
