Abstract
The present invention relates to a rust removing and phosphorizing agent for surfaces of black metal parts, which is an enriched mixture which is formed by mixing phosphonic acid, sodium carbonate, sodium triphosphate, etc. The present invention is suitable for removing rust on the surfaces, phosphorizing the surfaces and removing the light oil stains on the surfaces for black metal parts in the preceding processes of a paint spraying process, a paint coating process, a paint baking process and an electrostatic spraying process. The present invention has the characteristics of no harmful ions, such as nitrite, heavy metallic salt, etc., no poison, no irritating odor, no damage to skin, no environmental pollution and no public nuisance. The present invention can be used for removing rust on the surfaces of the black metal parts and phosphorizing the surfaces of the black metal parts under ordinary temperature; the rust stains on the surfaces of complicated parts can also be removed, and thus, the parts can not peel and can not rust after the parts are coated with paint. The present invention also has the advantages of simple and easy operation.
Description
Product of the present invention relates to a kind of derusting phosphating agent that is exclusively used in ferrous metal product surface.Be more specifically to a kind of novel no water-washing type phosphatizing liquid, its except can have rust cleaning, phosphatization to steel surface, except that multiple functions such as slight greasy dirt, also can be used for the derusting phosphating before the surface lacquer, japanning, baking vanish, electrostatic spraying to various ferrous metal products, make to reach and do not prime, with regard to direct the derusting phosphating agent of finish paint through the product surface behind the derusting phosphating.
Existing method to the ferrous metal surface rust cleaning, the overwhelming majority are after adopting traditional derusting process of strong acid rust cleaning earlier, to carry out bonderizing again.Its shortcoming is that the strong acid smell is big, and contaminate environment is harmful.In addition, required station floor space is big when technological operation, and worker's groove consumption is many, simultaneously, also needs solution is heated, and wastes energy.And,,, and easily cause anti-rust because the alkali neutralization is not thorough especially at each slit of product and worm gear place with the product that this traditional technology method was handled, therefore, can not ensure the quality of products.
The inventor's purpose is to provide a kind of environmentally safe, harmless to human body, also can carry out the ferrous metal product at normal temperatures, simple derusting phosphating is handled, and can guarantee the product surface to the profile complexity again, thoroughly derusting phosphating, can reach the product after the processing too, behind lacquer, there is not anti-rust, non-scale, guaranteeing to coat with lacquer the derusting phosphating agent of quality.
The know-why of product of the present invention is performed such, and chooses raw materials such as required phosphoric acid, yellow soda ash, tripoly phosphate sodium STPP, tertiary sodium phosphate, tartrate, promoting agent, sequestrant standby by technical requirements earlier.And liquid starting material diluted on request, solid material is dissolved on request, again with above dilution with dissolve good liquid starting material, send in the mixing tank, mix certain hour at normal temperatures after, obtain its mixture.In order to make the product surface reach ideal derusting phosphating effect and product of the present invention in the usage period, can guarantee its stability, erosion resistance, weather resistance.To the compatibility mass parts of above each component, passed through long experiment back and determined.
Following table has illustrated the compatibility situation of raw materials quality part of product of the present invention.
| Sequence number | Material name | Mass parts (%) |
| 1 | Phosphoric acid | 45 |
| 2 | Yellow soda ash | 1.0 |
| 3 | Tripoly phosphate sodium STPP | 2.0 |
| 4 | Tertiary sodium phosphate | 1.0 |
| 5 | Tartrate | 2 |
| 6 | Promoting agent | 2 |
| 7 | Sequestrant | 2 |
| 8 | Water | 45 |
| 9 | Add up to | 100 |
Accompanying drawing is the technological process of production figure of product derusting phosphating of the present invention agent.
Learn from accompanying drawing, product of the present invention must weigh up mass parts by technical requirements respectively to liquid starting material and solid material when producing after, preparation respectively.As to all required liquid starting materials, should dilute earlier, after again all required solid materials being dissolved, send mixing tank together to diluting good liquid starting material and dissolving good solid material, after mixing, measure its mixing quality, after secondary mixes again, measure its qualified degree, can then, check, capping, finished product warehouse-in.Need to prove raw material phosphoric acid wherein, is to add an amount of water in 45 parts pure phosphoric acid, make its dilution after, again 2 parts tripoly phosphate sodium STPP is directly put in the phosphoric acid diluent, in addition diluted mixture; For wherein yellow soda ash then is to take blended behind the abundant thin up; For tartrate wherein, after need adding an amount of water in addition and dissolving separately, mixed again.
In order to further describe derusting phosphating agent of the present invention at production with the situation in using, below illustrated with embodiment.
Embodiment one: (finished product)
Earlier that product of the present invention is required starting material:
5 parts of phosphatase 24s; 1 part in yellow soda ash; 2 parts of tripoly phosphate sodium STPPs;
1 part of tertiary sodium phosphate; 2 parts in tartrate; 2 parts of promoting agents;
After 2 parts of sequestrants weigh up respectively, in 45 parts phosphoric acid, add earlier an amount of water dilution;
In 2 parts tartrate, add an amount of water dilution again; And then the yellow soda ash of 1 part of mass parts added an amount of water, it is standby to make it fully dissolve the back; Tripoly phosphate sodium STPP, the tertiary sodium phosphate of 2 parts of mass parts are directly knocked down in the phosphoric acid solution for preparing and mixed; At last, the yellow soda ash after will dissolving again, tartaric acid solution, promoting agent, sequestrant carry out normal temperature and mix its qualified degree of back detection next time respectively by above mass parts, and secondary mixes again, after the assay was approved, carries out can.Press the 25Kg can for every jar during can, after the can censorship qualified after, finished product warehouse-in.
Embodiment two: (infusion method)
With the finished product derusting phosphating agent of the embodiment of the invention one, with 1: 2 thin up, earlier the pre-treatment product is carried out skimming treatment, behind the Ex-all grease, use flushing with clean water, and drain well.Put into then in the above solution of getting ready and soak, carry out derusting phosphating and handle, use the final mean annual increment solution of embodiment one to add water at 1: 4 again,, carry out disposable Passivation Treatment (rinse fast to wash and get final product) the product behind the derusting phosphating.
Embodiment three: (brushing method)
With finished product derusting phosphating of the present invention agent with 1: 0.5-1: 2 thin ups, to slight rust and greasy dirt, can use cotton or hairbrush earlier, the diluting soln brushing 1-2 that is stained with 1: 2 is all over getting final product; Can carry out brushing with 1: 1 solution for moderate corrosion product handles; For the severe dirty product that becomes rusty, can adopt 1: 0.5 solution or directly use finished product stoste of the present invention, brushing 3-5 time, dry then or dry with dried cloth.
