Abstract
The present invention relates to multifunctional phosphorized liquid at ultralow temperature, which contains phosphoric acid and dihydric phosphate. The phosphorized liquid is prepared with a method that different additives and accelerating agents are selected,and the working temperature of phosphorized liquid at normal temperature can descend to 0 to -15 DEG C,and heating is not needed. The present invention has the advantages that the phosphorized liquid can save energy,simplify the working processes, shorten the production period,and enhances the production efficiency,and the phosphorized liquid does not contain chromate,nitrite and other harmful substances, has no gas bubble or acid mist or no discharge of three waste generally,improves the working environment, and creates favorable conditions for linkage operation.
Description
The invention belongs to the metallic surface process field.
Traditional phosphating process is before the phosphatization oil on the metallic surface and rust (oxide skin) to be used alkali cleaning, and pickling after the neutralization, is carried out bonderizing then on metallic matrix.Phosphatization is to form one deck chemical conversion membrane process in the metallic surface, and this layer phosphatize phosphate coat mainly plays antirust and the bottoming effect, has to show land raising paint film adhesion and solidity to corrosion.What at present, phosphating process was with the most use is middle temperature (45-80 ℃) and low temperature (30-40 ℃) phosphatization.Chinese patent CN1057681A and CN1066894A have reported room temperature (12-35 ℃) phosphatization liquid respectively, but all must heat during these phosphatization liquid work, keep certain temperature, facility investment is big, has a large amount of gas bags to produce during phosphatization, causes acid mist, work under bad environment, not only the energy consumption height has three-waste pollution, is difficult to the operation that links.Low temperature (below 18 ℃) phosphatization polyphyly crystallite phosphatization, the middle temperature phosphating film that character such as sticking power are more traditional is good, but this film formation at low temp speed is slow, and film is too thin, and poor stability is both at home and abroad still in development and development phase.
In recent years, another problem of phosphating process research is multi-functional or claims comprehensive phosphatization liquid, and traditional phosphating process is comprised oil removing, rust cleaning (descaling), and operations such as phosphatization, passivation are simplified, and shorten operation, reduce facility investment, alleviate labor strength.The report that therefore, so-called " two-in-one ", " three-in-one ", " four unifications " phosphatization liquid novel process are arranged.This new phosphide liquid has multi-functional, and the function that particularly descales is very important, and it is exactly sand-blast that traditional rust cleaning descales except that pickling, and labour intensity is big, and workpiece deformation is big, and noise is big, operator's tin lung disease that is easy to get; Little oxygen of employing or anaerobic method for annealing are arranged, make workpiece surface be difficult for form thicker oxide skin, also have and adopt high acidity phosphatization liquid to descale, but according to people's such as Machu one-tenth film theory, under the high acidity be difficult to film forming, so the freeness of phosphating solution at room temperature should be low as far as possible.Therefore, phosphating solution at room temperature does not have the function that descales substantially.
The objective of the invention is to provide at the deficiencies in the prior art a kind of low temperature multifunction phosphide liquid it can work below 0 ℃, minimum operating temperature is-15 ℃, need not heat, energy consumption is reduced to minimum, it has multiple functions such as degreasing and rust removal (descaling) phosphatization passivation, and room temperature (below 25 ℃) phosphatization does not have acid mist, reduces environmental pollution, for interlock creates favorable conditions
Low temperature multifunction phosphide liquid provided by the invention, recipe ingredient (in the content in every liter of phosphatization liquid) be:
Phosphoric acid (85% industry) 130-350 milliliter/liter
Dihydrogen phosphate (phosphoric acid dihydro zinc, SODIUM PHOSPHATE, MONOBASIC, monocalcium phosphate, phosphoric acid
Dihydro nickel, or biphosphate cobalt) the 5-70 grams per liter
Promotor (available sodium chlorate, a nitro-sulfonic acid sodium or
SODIUMNITRATE) 1-10 grams per liter
Additive (available yellow prussiate of potash, ammonium citrate, trolamine,
Thiocarbamide or molybdic acid peace) the 0.01-10 grams per liter
Tartrate 2-15 grams per liter
OP 10 1-10 grams per liters
Water is added to 1 liter
At room temperature, take by weighing material contained in the phosphatization liquid by above-mentioned prescription, add respectively in the entry, the back that stirs adds the OP10 emulsifying agent, is mixed with the phosphatization aqueous solution.The free acidity of this phosphatization liquid is the 180-520 point, and total acidity is the 450-1400 point, and working temperature is-15～40 ℃, and the working hour is 0.5-15 minute.
Phosphatization liquid of the present invention use and coating method very easy, available spray, paint the immersion process primary coating on workpiece surface, general carbon steel is not washed with water, steel alloy can adopt seasoning or warm air drying then with washing.Between the phosphatization liquid usage period, when free acid is lower than certain value, adds fresh phosphatization liquid and make it free acidity and remain on more than the certain value, continue to use and do not have a discharging of waste liquid.
Phosphatize phosphate coat character (pressing GB6807-86) is measured:
The heavy 0.5-2 gram/rice of film
2
Outward appearance ash-grey black look
Indoor rust-proof life was greater than 7 days
3% salt water immersion test was greater than 1 hour
The sticking power one-level
The present invention has following advantage:
1. select different additives, promotor, the working temperature of high acidity phosphatization liquid can be dropped to 0--15 ℃, need not heat, a large amount of conserve energy are simplified working process, and have shortened the production cycle, have improved production efficiency.
2. this phosphatization liquid does not contain objectionable impuritiess such as chromic salt, nitrite, is working below 25 ℃, does not generally have bubble or bubble seldom, can not produce acid mist, the no three wastes, and pollution-free problem has been improved Working environment, for condition has been created in the interlock operation,
3. this phosphatization liquid alramenting to alloyed steel work-piece when being lower than 10 ℃ has special superiority.General phosphatization liquid can not film forming under this temperature, and this phosphatization liquid film forming properties is good, and indoor rust-proof life can also can be avoided hydrogen embrittlement more than half a year.Therefore can replace chemical oxidation, need not paint and be coated with slushing oil and preserve.
4, water phosphatization liquid can be adjusted prescription and additive and obtain the product of extensive use in a big way, can be used as " two-in-one ", " three-in-one ", phosphatization liquid uses " four unifications ", also can be iron mesentery or zinc mesentery product.
5. this phosphatization liquid adopts domestic commercially available common industrial chemicals, produces easily, and cost is low, and is of many uses, remarkable in economical benefits.
