Abstract

The invention discloses a method for coloring aluminum pigment by 5-sulfosalicylic acid dihydrate-iron ion complexes. The method mainly includes the two steps of firstly, using a silane coupling agentand ethyl orthosilicate as precursors in an alcohol system to synergistically hydrolyze the aluminum pigment by coating modification, so that the surface of the modified aluminum pigment contains a great quantity of exposed aminos; then, subjecting the synthesized 5-sulfosalicylic acid dihydrate-iron ion complexes to acylating chlorination, and making the synthesized 5-sulfosalicylic acid dihydrate-iron ion complexes subjected to acylating chlorination react with the aminos exposed on the surface of the aluminum pigment, so that the aluminum pigment is colored. The aluminum pigment prepared by the method is gorgeous in color, highly resistant to corrosion, high in glossiness and good in dispersity and can be widely applied to coating, printing ink and free spraying.

Description

technical field [0001] The invention relates to a method of using 5-sulfosalicylic acid iron ion complex to color aluminum pigments. The synthesized 5-sulfosalicylic acid iron ion complex organic dye is grafted on APTES / TEOS by chemical reaction. Aluminum pigment surface after synergistic hydrolysis modification. Background technique [0002] Aluminum pigment is an aluminum powder with a smooth and extremely thin flake structure. Because it can reflect visible light, it has a silver-white metallic effect. It is commonly known as aluminum silver powder or aluminum silver paste. It is one of the most widely used metal effect pigments. [0003] With the development of society, the advancement of science and technology and culture, people's requirements for beautification of commodities have also increased accordingly. Colored aluminum powder has the characteristics of bright color, strong corrosion resistance, high insulation, not easy to fade, strong metallic luster, and low ...
