Abstract

The invention discloses an aqueous cleaning and rust-proof agent. The aqueous cleaning and rust-proof agent is characterized by comprising a cleaning agent, nitrite, an addition agent used for adjusting the pH value of solution, glycerinum and water, wherein the cleaning agent, the nitrite, the glycerinum and the addition agent are added into water for stirring and mixing to form the homogeneous solution. The aqueous cleaning and rust-proof agent has the benefit effects that a layer of complex compound is formed on the surface of metal after the ferrous metal is cleaned, so that after cleaning, the rust-proof treatment of the ferrous metal is finished simultaneously, the oiling process is omitted, and the cost is effectively reduced.

Description

The water-based cleaning anti-rust agent
Technical field
The present invention relates to a kind of cleaning rust-proof liquid.
Background technology
Ferrous metal for preventing surface corrosion, must not have the antirust processing of application after cleaning, for example apply rust-preventive agent on the surface.The prior art metallic surface is antirust, and early using has rust-proof effect slushing oil preferably, forms one deck protectiveness oil film in the metallic surface by slushing oil, in the secluding air steam to corrosion of metal, thereby it is antirust to reach the long period.Yet use slushing oil, not only need to consume a large amount of oil plant raw materials, aggravated energy consumption, and in following process (for example weld, paint, electroplate, assemble) and unpacking, all need to clean oil removing, not only produce a large amount of oily waste liquor dischargings of cleaning, cause the pollution to environment, and the cleaning oil removing is time-consuming, also can increase cost.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of water-based cleaning rust-proof liquid, make the two procedures that oils after traditional need the cleaning ferrous metal become after the cleaning directly antirustly, therefore omitted the operation that oils, also reduced the input of the equipment that oils.
The present invention is achieved through the following technical solutions: the water-based cleaning anti-rust agent, it is characterized in that: comprise clean-out system, nitrite, be used for additive, the G ﹠ W of regulator solution pH value, described clean-out system, nitrite, glycerine, additive are put into water, mix the formation uniform solution.
Described additive is any one or its combination in Sodium phosphate dibasic, yellow soda ash, the sodium bicarbonate.
Each component has following mass ratio in the described water-based cleaning anti-rust agent: clean-out system: nitrite 1%~5%: glycerine 3%~7%: additive 1%~5%: water 3%~7%: 76%~92%.
The present invention has following beneficial effect: ferrous metal being cleaned metallic surface, back formation one deck complex compound, therefore finish the antirust processing to ferrous metal simultaneously after having cleaned, omitted the operation that oils, effectively reduced cost.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail: embodiment 1: the water-based cleaning anti-rust agent, comprise clean-out system, nitrite, be used for additive, the G ﹠ W of regulator solution pH value, described clean-out system, nitrite, glycerine, additive are put into water, mix the formation uniform solution, described additive is Sodium phosphate dibasic.
Each component has following mass ratio in the described water-based cleaning anti-rust agent: clean-out system 1%, nitrite 3%, glycerine 1%, additive 3%, water 92%.
This water-based cleaning anti-rust agent, the mass ratio of various components (it is outer to dewater) is little, so production cost is low, and has cleaning rust-proof effect preferably.
Embodiment 2: the water-based cleaning anti-rust agent, and comprise clean-out system, nitrite, be used for additive, the G ﹠ W of regulator solution pH value, described clean-out system, nitrite, glycerine, additive are put into water, mix the formation uniform solution.
Described additive is any one or its combination in Sodium phosphate dibasic, yellow soda ash, the sodium bicarbonate.
Described composition has following mass ratio: clean-out system 5%, nitrite 7%, glycerine 5%, additive 7%, water 76%.
This water-based cleaning anti-rust agent, implementation cost is higher, and the cleaning rust-proof effect is general.
Embodiment 3: the water-based cleaning anti-rust agent, and comprise clean-out system, nitrite, be used for additive, the G ﹠ W of regulator solution pH value, described clean-out system, nitrite, glycerine, additive are put into water, mix the formation uniform solution.
Described additive is any one or its combination in Sodium phosphate dibasic, yellow soda ash, the sodium bicarbonate.
Described composition has following mass ratio: clean-out system 3%, nitrite 5%, glycerine 3%, additive 5%, water 84%.
Each component reasonable ratio among the embodiment 3 does not need too high implementation cost when guaranteeing the cleaning rust-proof effect.
Glycerine among the present invention: can be miscible with any ratio with water, be mainly used in reducing the freezing point of water, prevent from freezing easily when scavenging solution from using under the lower situation of temperature.
Additive is mainly regulated as the pH value of solution, generally adopts Sodium phosphate dibasic, guarantees that solution can be alkalescence, and Sodium phosphate dibasic is colourless monoclinic system crystal or white powder, and is water-soluble, and its aqueous solution is weakly alkaline, and 1% pH value of aqueous solution is 8.8~9.2; In this agent, can guarantee that the solution pH value is between 8-10 as the stablizer of solution.
Clean-out system is mixed with by tensio-active agent (as sodium alkyl benzene sulfonate, sodium alkyl sulfate) and various auxiliary agent (as tripoly phosphate sodium STPP), auxiliary, has good infiltration, wetting, dispersion, emulsifying property, advantage such as soil release characteristics is strong, price is low.
Nitrite mainly adopts Sodium Nitrite, and Sodium Nitrite and metal generate the film (oxide film) that provide protection is arranged, and the oxide compound that generates indissoluble covers protects the positive column on the metallic surface, cause the increase of anodic polarization, thereby suppresses the anodic process of metal.
