Problems solved by technology

Not only is it required to have a unique 3D stereoscopic effect, but it is also required to have good anti-mold performance. However, the aluminum pigments currently on the market are generally not magnetic, and cannot be oriented according to the direction of the magnetic field under a magnetic field. When the coating is dry, it cannot be formed. Good three-dimensional artistic effect, but also has the disadvantage of poor mildew resistance. Therefore, it is urgent to develop a new type of mildew-resistant magnetic aluminum pigment to meet market demand

Abstract

The invention discloses a moldproof magnetic aluminum pigment and a preparation method thereof. The moldproof magnetic aluminum pigment is prepared from the following raw materials in parts by weight: 60-80 parts of modified aluminum powder, 80-100 parts of turpentine, 10-15 parts of perfluoro-polyether, 5-10 parts of polyoxyethylene avocado oil acid ester, 10-15 parts of basic bismuth chloride, 3-6 parts of trimethylolpropane trioleate, 2-4 parts of fatty acid lactyl ester, 5-10 parts of lithium magnesium silicate, 2-4 parts of behenoyl polydimethylsiloxane, 15-20 parts of bowlder powder, 4-6 parts of salicylanilide and 5-10 parts of silver-carried zirconium phosphate. The magnetic aluminum pigment has excellent bactericidal and moldproof properties, can not become moldy in a wet environment, and has the advantages of excellent weather resistance, excellent chemical resistance, excellent heat resistance and wide market prospects.

Description

technical field [0001] The invention discloses an anti-mildew magnetic aluminum pigment and a preparation method thereof, belonging to the field of aluminum pigments. Background technique [0002] Aluminum pigment is a scale powder. Compared with other pigments, it has unique properties such as covering the substrate, physical shielding, two-color effect, floating and metallic glitter effect, and is widely used in pigments, coatings, inks, paints and other industries. In recent years, with the continuous improvement of my country's economic level and the rapid development of the modern coating industry, people have a deeper understanding and higher requirements for the quality of decoration. Therefore, the demand for aluminum pigments has gradually increased. The requirements are also getting stricter. Not only is it required to have a unique 3D stereoscopic effect, but it is also required to have good anti-mold performance. However, the aluminum pigments currently on the ma...
