Embodiment 1

[0017] A preparation method of corrosion-inhibiting water-based aluminum pigment, comprising the steps of:

[0018] (1) Aluminum powder surface elution treatment: Disperse the aluminum powder in isopropanol, disperse it ultrasonically at 30-40°C for 1-2 hours until uniform, leave it for 30-60 minutes, filter, and ultrasonically wash with deionized water for 5- 8 times, spare;

[0019] (2) Surface hydroxylation treatment: put the aluminum powder eluted from the surface in step (1) into the aqueous solution of phenol ether phosphate, after ultrasonic dispersion, add a certain amount of nickel sulfate, and stir at 30-40°C 2 to 3 hours to complete the surface hydroxylation treatment; wherein, the mass ratio of the aluminum powder, phenol ether phosphate and nickel sulfate is 10 to 13:1:0.1 to 0.3, and the water content in the phenol ether phosphate is the mass of the aluminum powder 100~300% of

[0020] (3) Mixing coating treatment: put the mixed solution after the hydroxylation...

Abstract

The invention discloses a method for preparing a corrosion inhibition waterborne aluminum pigment. The method comprises the following steps: a step (1) of aluminum powder surface elution treatment; a step (2) of surface hydroxylation treatment; and a step (3) of mixing coating treatment. The method for preparing the corrosion inhibition waterborne aluminum pigment is simple and convenient to operate and easy to implement. According to the method, through aluminum powder surface elution treatment, hydroxylation treatment, slow release treatment and coating treatment, the coating stability of the aluminum pigment surface is improved effectively, the aluminum pigment is prevented from being in contact reaction with water or an air medium, the slow release performance of the aluminum pigment is improved remarkably, and the prepared aluminum pigment is high in stability, good in glossiness and wide in application prospect.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a method for preparing corrosion-inhibiting water-based aluminum pigments. Background technique [0002] Flaky aluminum pigment has the advantages of good dispersibility, strong adhesion, vivid color, good light reflection effect and long-lasting brightness. An important metallic pigment. However, aluminum pigments (flaky aluminum powder), which have been widely used in oil-based paints, are not suitable for water-based paints because aluminum is prone to exothermic and outgassing reactions with water, which leads to a decrease in the gloss of aluminum pigments. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a preparation method of corrosion-inhibiting water-based aluminum pigment, which can solve the problem that the existing aluminum pigment easily interacts with corrosive environment media such as water and air and deter...
