Abstract
The invention provides a rust-removing and anti-rusting agent for iron and steel, which mainly solves the technical problems that the existing rust-removing and anti-rusting technology has large labor intensity, does not remove rust thoroughly, and produces pollution easily and the like. The point of the technical scheme is that the solution is prepared by taking phosphoric acid as main material and adding materials therein; the weight proportion of the materials is obtained by stirring and mixing: 200-300 parts of de-ionized water, 100-160 parts of phosphoric acid, 1-8 parts of Marifu salt, 1-8 parts of dihydrogen phosphate, 5-10 parts of gallotannic acid and 0.5-2 parts of nickel nitrate. The rust-removing and anti-rusting agent can directly transform the surface rust of the iron and the steel under a rusting-free condition, thereby finishing the rusting treatment and corrosion resistance, obviously improving labor efficiency, reducing processing cost, and improving corrosion resistance of the surface of the iron and steel and a paint coating. The rust-removing and anti-rusting agent is widely applied in the fields such as machine manufacturing, locomotive maintenance, ship manufacturing, bridge tower frame, steel construal plant and the like as the base material of the rust-removing and anti-rusting agent and the paint.
Description
Technical field
The present invention relates to a kind of steel derusting rust-preventive agent.Especially a kind of application bed material of exempting rust and conversion film corrosion proof function that has that is used for corrosion steel surface Coating Pretreatment.
Background technology
Current, continuous development along with industry, the usage quantity of iron and steel is also growing, but corrosion has brought problem also for the use of iron and steel, the annual iron and steel loss that causes because of corrosion is very surprising, existing tradition rust cleaning and antirust technology all have certain shortcoming, and, processing big such as labour intensity can not be thoroughly, be easy to generate pollution, corrosion resistance is undesirable or the like, need better technology and product to promote therefrom and perfect.
Summary of the invention
The steel derusting rust-preventive agent that the purpose of this invention is to provide that a kind of changing effect is good, more convenient operation, environmental-protecting performance is higher.
The technical solution adopted for the present invention to solve the technical problems is: it is main raw material with phosphoric acid and adds the formulated solution of batching therein, the weight proportion of each raw material be mix formulated: deionized water 200-300 part, phosphatase 11 00-160 part, Mazhev salt 1-8 part, primary zinc phosphate 1-8 part, Weibull 5-10 part, nickelous nitrate 0.5-2 part.
The screening formulation 1 of person's character invention, it is to press column weight amount proportion raw material mixed preparing to form: 250 parts of deionized waters, 04 part of phosphatase 11,3 parts of Mazhev salts, 3 parts of primary zinc phosphates, 7 parts in Weibull, 1.2 parts of nickelous nitrates.
The screening formulation 2 of person's character invention, it is to press column weight amount proportion raw material mixed preparing to form: 200 parts of deionized waters, 50 parts of phosphatase 11s, 6 parts of Mazhev salts, 7 parts of primary zinc phosphates, 9 parts in Weibull, 1.5 parts of nickelous nitrates.
The screening formulation 3 of person's character invention, it is to press column weight amount proportion raw material mixed preparing to form: 200 parts of deionized waters, 04 part of phosphatase 11,1 part of Mazhev salt, 1 part of primary zinc phosphate, 5 parts in Weibull, 0.6 part of nickelous nitrate.
The present invention also can add other auxiliary agent in above-mentioned mix, described auxiliary agent comprises promoting agent, sustained release dosage or stablizer.
The invention has the beneficial effects as follows: the present invention is formed by mixed preparing such as phosphoric acid, manganese salt, zinc salt and nickel salts; in use is directly to be sprayed at the corrosion steel surface; the ferric oxide that steel surface forms because of corrosion can be dissolved and be absorbed and change into the composite metal salt protective membrane; therefore the present invention can directly carry out conversion processing to the steel surface corrosion under the condition of exempting rust; thereby reach that corrosion is handled and anticorrosively once finish, can obviously raise labour efficiency, reduce the corrosion resistance of processing cost, lifting steel surface and paint coating.The present invention is not limited by weather and place in construction, do not need to add gentle specific equipment, do not produce pollution, easy to operate, small-sized iron and steel parts and large-scale steel structure all are suitable for, therefore the present invention can be widely used in fields such as machinofacture, locomotive maintenance, Ship Building and Repairing, bridge pylon, steel structure factory building, as bed material before derusting anti-corrosive and the paint.
Embodiment
The present invention is to be main raw material with phosphoric acid and to add the formulated solution of batching therein, the weight proportion of each raw material be mix formulated: deionized water 200-300 part, phosphatase 11 00-160 part, Mazhev salt 1-8 part, primary zinc phosphate 1-8 part, Weibull 5-10 part, nickelous nitrate 0.5-2 part.The present invention in case of necessity also can add other auxiliary agent in above-mentioned mix, described auxiliary agent comprises promoting agent, sustained release dosage or stablizer, and the amount of auxiliary of adding is to add promoting agent 0.01-1 part, sustained release dosage 0.05-1 part or stablizer 0.5-1 part on the basis of above-mentioned weight ratio.Hence one can see that, and the present invention is formed by mixed preparing such as phosphoric acid, manganese salt, zinc salt and nickel salts.When using product of the present invention that the corrosion steel surface is handled, the present invention directly can be sprayed at rusty surface at normal temperatures at floating rust, scale, moderate corrosion and thin oxide skin, bubble and scale can be earlier with spraying solution of the present invention after the instrument cleaning at heavily becoming rusty, becoming rusty, it can dissolve and absorb iron rust fast and change into a kind of composite metal salt chemical films, form good anticorrosive bottom attached to steel surface, as anticorrosion bed material before the paint.The present invention can directly carry out conversion processing to the steel surface corrosion under the condition of exempting rust, thereby reaches that corrosion is handled and anticorrosively once finish, and can obviously raise labour efficiency, reduce the corrosion resistance of processing cost, lifting steel surface and paint coating.
Below in conjunction with embodiment the present invention is described in further details.
Embodiment 1, and it is to press column weight amount proportion raw material mixed preparing to form: 250 parts of deionized waters, 04 part of phosphatase 11,3 parts of Mazhev salts, 3 parts of primary zinc phosphates, 7 parts in Weibull, 1.2 parts of nickelous nitrates.
