Description
Technical field
The invention belongs to surface conditioning agent fields, and in particular to a kind of colloidal sol melanism metal conditioner.
Background technology
Metal conditioner refers to the general name for the chemical agent that various processing are carried out to metal surface.Treatment of Metal Surface packet
The substrate pretreatments such as oil removing, derusting, phosphatization, antirust have been included, have been prepared for metal coating techniques, metal protection technology, base
Body pre-treatment quality prepares hereafter coating and the use of metal has a great impact, and water soluble anti-rust agent therein then can dissolve
Aqueous solution is formed in water, and metal can prevent rust corrosion after the processing of this aqueous solution.Their anti-rust action can be divided into three
Class.
1. metal generates insoluble and fine and close sull with antirust agent, thus prevents the anodic solution or rush of metal
Into the passivation of metal, so as to inhibit corrosion of metal.This kind of antirust agent is also known as passivator, such as sodium nitrite, potassium bichromate.
When in use, enough dosages be should ensure that.During dosage deficiency, it is impossible to form complete sull, it is not covered very
On small metal surface, corrosion electric current density increase easily causes severe local corrosion.2. the salt of metal and antirust agent generation indissoluble
Class, so as to which metal be made to be isolated with corrosive medium, from corrosion.Such as：Some phosphate can act on iron and generate insoluble phosphorus
Sour molysite；Some silicates can generate insoluble silicate etc. with iron, aluminium effect.3. metal and antirust agent generation slightly solubility
Complex compound is covered in metal surface and protects the metal from corroding.Such as：Benzotriazole can generate chelate Cu with copper
(C6H4N3) 2, it is both not soluble in water to be also insoluble in oil, thus the surface of copper can be protected.
At present, although traditional phosphate conversion and chromating process for treating surface can obtain good effect,
It is but right containing the carcinogens such as the heavy metal ion such as zinc, manganese, nickel, chromium and sub- environmental protection fluorine-free in the waste liquid discharged in processing procedure
Environmental pollution is very serious, and metallic surface silanization treatment technology is not due to being related to environmentally hazardous substance, production technology energy
It consumes that low, technical applications are extensive, is considered being expected to the processing of substitution phosphate conversion and chromating processing, is metal surface
Individually protection latest development direction.
