Abstract
The said liquid contains phosphoric acid, nitric acid, aluminium powder, zinc oxide, gelatin,e tc. The surface of iron and steel parts treated with the said liquid has a smooth and dense rustproof phosphorized layer.
Description
The present invention relates to the derusting rust-proofing of metallic surface derusting rust-proofing, particularly iron and steel.
Metallic surface, particularly steel surface contact meeting and get rusty because of oxidation corrosion with surrounding medium.The main component of its corrosion layer is metal oxide or oxyhydroxide etc., such rusty scale short texture, porous, and have water absorbability, thus accelerate corrosion of metal speed, metal products is destroyed rapidly.
At present, the existing method that the metallic surface is handled, not only complex procedures, labour intensity big (especially handling the hardware that has got rusty), efficient are low, and contaminate environment.Particularly after the rust cleaning, hardware is faced with the problem of getting rusty again, need carry out antirust processing or rotproofing again.
The purpose of this invention is to provide a kind of derusting phosphating liquor, the existing good rust cleaning effect of this feed liquid can form preservative coat in the metallic surface again.
The weight proportion of derusting phosphating liquor of the present invention is as follows:
Phosphatase 24 9-60%,
Nitric acid 20-30%,
Aluminium powder 0.5-5%,
Zinc oxide 1-5%,
Gelatin 1-5%,
Alum 0.5-2%,
Tartrate 0.5-2%,
Hexamethylenetetramine 0.5-2%.
Utilize feed liquid of the present invention, can carry out surface treatment to steel product and component at normal temperatures, particularly the iron and steel parts surface of having got rusty be handled, can remove rust, metallic surface after the processing forms the phosphate coating of the smooth bright and clean densification of one deck, to reach the effect that prevents metallic corrosion.Through the boucherizing spot test, show that rete is stable, derusting rust-proofing is functional.As rust-proofing primer, effect is also splendid with this phosphate coating.
Further specify the present invention with embodiment below.
Embodiment
Get phosphoric acid, nitric acid, aluminium powder, zinc oxide, gelatin, alum, tartrate and hexamethylenetetramine, prepare by following weight ratio:
Phosphoric acid 56%,
Nitric acid 28%,
Aluminium powder 3.5%,
Zinc oxide 4%,
Gelatin 4%,
Alum 1.5%,
Tartrate 1.5%,
Hexamethylenetetramine 1.5%.
This feed liquid using method is that after with sand paper or emery cloth tentatively being polished in the iron and steel parts surface of getting rusty, the band rust is brushed the above feed liquid, or leaches described feed liquid, is positioned in the air to get final product.Steel surface after the processing forms the phosphate coating of the smooth bright and clean densification of one deck, and rete is stable, and the derusting rust-proofing effect is splendid.
