Information about Water-based aluminum paste
Aluminium paste is a kind of metallic pigment that form through grinding with ball aluminum powder mixed organic solvents and auxiliary agent.The aluminium powder of producing in prior art mostly is oiliness. And oiliness aluminium powder drops in water-borne coatings, not only can not disperse, and generate other material because aluminium and water can react, gained lacquer painting poor-performing, color is gloomy. For making in water dispersed aluminium paste preferably, the conventional means of people are for to be coated and to be made by silicon.
But in the water of this method gained water-based aluminium paste, dispersiveness is still poor. Old friends continue this method to make multiple improvement, the new method is increased comb-shaped polymer on the coated basis of silicon, to increase aluminium flake after the silicone covering consistency in water. But comb-shaped polymer used needs to synthesize and increased working strength in addition, and has increased the operation in water-based aluminium paste production process.
This new method is to solve oiliness aluminium paste, for water-borne coatings, is difficult for disperseing and the gloomy color on account of technical problem.
For achieving the above object, according to an aspect of the present technology, provide a kind of preparation method of water-based aluminium paste, comprised the following steps: after washing oiliness aluminium paste, it is carried out that silicon is coated obtains water-based aluminium paste, silicon encapsulation.
