The enhancing of knowledge, the appearance of national environmental protection policies and regulations, it is imperative to imitate metallic paint Water-borne modification.
Cu-Zn alloy powder, can not in water paint and ink due to there is the addition of the lipophilicity substances such as stearic acid in grinding technics
Dispersion, and the erosion due to substances such as water, acid, alkali, oxygen to copper, zinc are easy to cause Cu-Zn alloy powder appearance change colour, reunite, emitting
The problems such as bubble.It is used to stablize Cu-Zn alloy powder in water-based system, needs for Cu-Zn alloy powder to be surface-treated.Existing Cu-Zn alloy powder
Surface treatment have and handled using chromium compounds, or form silicon dioxide film with collosol and gel, or double using organic-inorganic
Layer cladding.But environment can be caused greatly to pollute by being handled using chromium, application is restricted；The speed of collosol and gel
Be difficult to uniform, and Cu-Zn alloy powder surface is irregular, the silicon dioxide film of formation there are it is imperfect easy to fall off the problems such as；Using organic nothing
Machine double-coating, manufacturing process is cumbersome, need to expend a large amount of manpower and material resources, and in manufacturing process with many ethyl alcohol come
It cleans and works as solvent, pole is not environmentally.
Therefore, how to overcome existing Cu-Zn alloy powder surface treatment cladding it is insecure it is imperfect, form and aspect are unstable and uneconomical
The defect of environmental protection is industry urgent problem to be solved.
Summary of the invention
