Abstract
The invention provides an environment-friendly rust-removing anti-rust agent. The agent consists of the following raw materials, by weight: 5%-20% of diethylene glycol monobutyl ether, 10-15% of KOH, 5-10% of oxalic acid, 5-10% of gluconic acid, 5-10% of phosphate, 2-5% of potassium tetraborate and the balance of deionized water. The environment-friendly rust-removing anti-rust agent provided by the invention has good rust-removing and anti-rust performance, and is healthful and environment-friendly. The environment-friendly rust-removing anti-rust agent can be diluted with 0-50 times of water and used for rust removal and rust prevention under different processing processes and different conditions.
Description
Technical field
The invention belongs to metal rust preventing technical field, be specifically related to a kind of environment-friendly type rust-removing and-preventing agent.
Background technology
Mechanicals will be used metallic substance mostly, in manufacturing processed, to removing unavoidably corrosion product, carries out rust prevention during manufacture; After product is made, in delivery, stock, use procedure, all may be subject to oxygen in environment or the erosion of acid-alkali medium, carry out antirust, to the corrosion having occurred, also will eliminating rust, it is antirust to carry out again, traditional water-based antirust agent generally uses nitrate, nitrite and dichromate etc. to have the composition of carcinogenic teratogenesis to carry out antirust processing, and the health to workman and the pollution of environment have very large negative impact.
Summary of the invention
The object of the invention is to: overcome the deficiencies in the prior art, a kind of environment-friendly type rust-removing and-preventing agent is provided, to replace original traditional rust-preventive agent take nitrate, nitrite and dichromate as main component.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of environment-friendly type rust-removing and-preventing agent, is prepared from by the raw material mixed dissolution of following weight percent:
The preparation method of above-mentioned environment-friendly type rust-removing and-preventing agent: take raw material by described weight percent, taken diethylene glycol monobutyl ether, potassium hydroxide, oxalic acid, gluconic acid, phosphoric acid, potassium tetraborate, add successively and in the deionized water taking, be heated to 50-60 ℃ and be stirred to all the components and dissolve completely, till container bottom sediment-free, cooling rear packing.
Beneficial effect of the present invention:
The present invention compared with prior art, has the following advantages:
Environment-friendly type rust-removing and-preventing agent of the present invention has good derusting rust-proofing performance, and health environment-friendly.
Diethylene glycol monobutyl ether is good tensio-active agent, can well remove the greasy dirt of metallic surface etc., convenient rust cleaning and antirust;
Oxalic acid, gluconic acid and potassium hydroxide reaction, the oxalate of generation and grape acid group can with the complexing of metal ion such as iron, copper, easily remove the corrosion of metallic surface;
Phosphate radical, hydrogen phosphate, dihydrogen phosphate that phosphoric acid and potassium hydroxide reaction generate can generate phosphoric acid molysite with iron ion reaction, are attached to metallic surface, effectively prevent that metal from continuing corrosion;
Potassium tetraborate can form in metallic surface the special protective layer of one deck, effectively prevents metallic corrosion;
Deionized water Main Function, for increasing solvability, makes the concentrated solution of preparation more stable, often contains the metal ion such as calcium, magnesium in non-deionized water, can affect the solvability of above composition.
Environment-friendly type rust-removing and-preventing agent of the present invention can with after 0-50 water dilution doubly for the derusting rust-proofing under different complete processings and different condition.
