Problems solved by technology

[0003] With the development of water-based coatings, traditional oily aluminum-silver pastes are difficult to disperse in water-based coatings due to the presence of a large amount of solvent oil, making them unsuitable for water-based coatings; aluminum pigments, one of the main raw materials for metallic inks, of course require corresponding requirements. be environmentally friendly
Therefore, it is necessary to overcome the problem that traditional solvent oils are not suitable for water-based coatings, and develop a green and environmentally friendly water-based aluminum-silver paste coating that is non-toxic and environmentally friendly, has a simple preparation process, and can adapt to modern large-scale production, and has attracted more and more attention from researchers. And it has very important practical significance and economic benefits for improving food safety level and technological innovation

Description

technical field [0001] The invention relates to an aluminum pigment, in particular to a green and environment-friendly aluminum-silver paste. Background technique [0002] Aluminum silver paste is a kind of aluminum metal pigment. Its production method is to mix spherical aluminum powder, solvent oil, oleic acid and ball milling medium steel balls, and then grade and sieve after ball milling for 6-30 hours. It is a paste metal pigment obtained after kneading. . Aluminum silver paste has become the most widely used and researched metallic pigment due to its unique metallic luster effect, angle-dependent color effect, optical effect and suspension characteristics. [0003] With the development of water-based coatings, traditional oily aluminum-silver pastes are difficult to disperse in water-based coatings due to the presence of a large amount of solvent oil, making them unsuitable for water-based coatings; aluminum pigments, one of the main raw materials for metallic inks, o...
