Abstract
The invention discloses a copper alloy anti-rusting agent which comprises a rust remover, a passivator, a surfactant, a degreaser and pure water, wherein, the weight percentage of the rust remover is 10 percent to 20 percent, the passivator is 5 percent to 15 percent, the surfactant is 1 percent to 10 percent and the degreaser is 1 percent to 5 percent, and the rest is pure water. The copper alloy anti-rusting agent is a water-soluble cleaning agent, has good dust-removing effect to the surface of copper alloy, little corrosion, high-efficiency degreasing performance and anti-rust function after cleaning, keeps an antioxidant surface for a long time, meets the requirements of environment protection and has the advantages of reasonably-designed formula, simple preparation technology and lower cost.
Description
Technical field
The present invention relates to rust remover, relate in particular to a kind of copper alloy antirust agent.
Background technology
Ferrous metal is meant iron, manganese, chromium and their alloy thereof.As steel, the pig iron, iron alloy, cast iron etc.The steel and the pig iron all are based on iron, are the alloy of main adding elements with carbon, are referred to as iron-carbon.The ferrous metal purposes is quite extensive, and a plurality of industries of iron and steel metallurgy industry, mechanical means manufacturing, shipbuilding, national defense industry, petroleum machinery industry, aircraft, automobile, motorcycle production, weaving, five metals, mould, instrument, medicine equipment industry, various iron and steel parts chromium plating, zinc-plated deep processing or the like can both be seen its figure.In order further to improve the quality of ferrous metal, guarantee that it in use has good surface appearance can be arranged, so it is carried out the derusting anti-corrosive processing at need.But the ferrous metal workpiece appearance through rust cleaning processing often has the pitted skin phenomenon, i.e. the rough defective of surface imperfection; Be exactly that easy generation the in surface scabbed in addition, reason is that steel material is inhomogeneous, and impurity is many, and the rust cleaning rear impurity is exposed to the outside, and generation scabs.The easy scratch of workpiece after the rust cleaning, burr can appear in rust cleaning back workpiece surface, workpiece and workpiece contact meeting scratch surface, the intensity of degree of depth scratch reduction workpiece.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that currently available products exists, and provide a kind of copper alloy antirust agent, it is a water-soluble washing agent, dirt, rust cleaning performance to the ferrous metal workpiece surface are good, corrodibility is little, not perishable, and the processing discharging of being convenient to discard clean-out system, requirement on environmental protection met; Formulating of recipe is reasonable, and preparation technology is simple, and cost is lower.
The objective of the invention is to realize by following technical scheme.
A kind of copper alloy antirust agent of the present invention is characterized in that, comprises pH regulator agent, passivator, tensio-active agent, removers, rust remover and pure water; Wherein, the weight percent of pH regulator agent is 15% to 30%, and the weight percent of passivator is 2% to 5%, the weight percent of tensio-active agent is 1% to 8%, the weight percent of removers is 1% to 7%, and the weight percent of solidifying agent is 1% to 5%, and all the other are pure water.
Aforesaid a kind of copper alloy antirust agent is characterized in that, described pH regulator agent is dilute hydrochloric acid, dilute sulphuric acid, rare nitric acid, oxalic acid.
Aforesaid a kind of copper alloy antirust agent is characterized in that, described passivator is Sodium orthomolybdate, chromic trioxide.
Aforesaid a kind of copper alloy antirust agent is characterized in that, described tensio-active agent is the one or more combination in tetramethyl-ammonium acetate, tetrapropyl ammonium acetate, the tetradecyl trimethyl ammonium chloride promoting agent.
Aforesaid a kind of copper alloy antirust agent is characterized in that, described removers is dehydrated alcohol, acetone, isopropylcarbinol.
Aforesaid a kind of copper alloy antirust agent is characterized in that cleaning agent for printed circuit board according to claim 1 is characterized in that, the described solidifying agent that goes is tin protochloride, stannous sulfate.
Aforesaid a kind of copper alloy antirust agent is characterized in that, its using method is that rust remover is heated between 40-50 ℃, and the metal that clean was dipped in this solution 4-5 minute, takes out to get final product.When using after 4-5 minute fully Ex-all greasy dirt rusty stain, can be according to the actual power of solution, the proper extension soak time is till Ex-all.
Embodiment
A kind of copper alloy antirust agent of the present invention, it comprises pH regulator agent, passivator, tensio-active agent, removers, rust remover and pure water; Wherein, the weight percent of pH regulator agent is 15% to 30%, and the weight percent of passivator is 2% to 5%, the weight percent of tensio-active agent is 1% to 8%, the weight percent of removers is 1% to 7%, and the weight percent of solidifying agent is 1% to 5%, and all the other are pure water.
A kind of copper alloy antirust agent of the present invention, wherein, described pH regulator agent is dilute hydrochloric acid, dilute sulphuric acid, rare nitric acid, oxalic acid; Described passivator is Sodium orthomolybdate, chromic trioxide; Described tensio-active agent is the one or more combination in tetramethyl-ammonium acetate, tetrapropyl ammonium acetate, the tetradecyl trimethyl ammonium chloride promoting agent; Described removers is dehydrated alcohol, acetone, isopropylcarbinol; The described solidifying agent that goes is tin protochloride, stannous sulfate; Its using method is that rust remover is heated between 40-50 ℃, and the metal that clean was dipped in this solution 4-5 minute, takes out to get final product.When using after 4-5 minute fully Ex-all greasy dirt rusty stain, can be according to the actual power of solution, the proper extension soak time is till Ex-all.
Principle of work of the present invention is: rust remover can be dissolved in water fully, the rusty stain on the removal ferrous metal workpiece surface that pH regulator agent wherein can be very fast, and under the cooperation of promoting agent, can not cause corrosion to workpiece; Passivator and solidifying agent have specially been selected in the rust remover for use, oxidized, corrosion that the workpiece surface that can effectively preserve value is difficult for for a long time after cleaning; Removers can effectively be removed the mechanical wet goods greasy dirt of being infected with in the workpiece process.
