example 1

[0018] Take 10g of self-made (see Chinese Patent Publication No. CN1741207) nano ferroferric oxide magnetic powder with a grain size of about 20nm, add 5g of aluminum powder, 5g of pearl powder in a container, add 50mL of absolute ethanol, 2g of Distilled water, 2mL of KH570 coupling agent, fully stirred, ball milled by planetary ball mill for 5h, magnetized and centrifuged, washed with absolute ethanol, dried at 80°C to obtain oily nano magnetic control pigment.

example 2

[0020] Mix 20 g of the magnetic control pigment prepared in Example 1 with 80 g of a commercially available glass coating, and mix and stir well to obtain a nano magnetic control coating. Place the small magnetic block in accordance with the designed magnetic circuit direction, place the glass to be sprayed on top of the small magnetic block, spray nano-magnetic control paint, and get a pattern with a specific effect after the paint dries.

example 3

[0022] Take 0.5g of self-made (see Chinese Patent Publication No. CN1741207) nano ferroferric oxide magnetic powder with a grain size of about 20nm, add 0.5g of silver powder, 4g of aluminum powder, 2g of magnesium powder, and 3g of sunfast yellow in the container Add 50mL of absolute ethanol, 0.2g of distilled water, and 0.2mL of KH550 coupling agent, stir well, mill for 5 hours in a planetary mill, separate with magnet and centrifuge, wash with absolute ethanol, and dry at 100°C to obtain oily Nano magnetron pigment.

Abstract

The invention relates to a nano magnetic controlled pigment and a preparation method thereof, belonging to an application of magnetic nano-materials in the coating field. The preparation of the nano magnetic controlled pigment is mixing the magnetic nano-materials with other pigments after surface treatment of the magnetic nano-materials, adding the obtained magnetic controlled pigment into other coatings, and stirring completely before obtaining the nano magnetic controlled coating. The nano magnetic controlled pigment prepared by the invention has directional movement or the tendency of directional movement under the effect of magnetic field; the nano magnetic controlled coating can achieve the effect of controlling pattern spray through controlling magnetic lines of force; the coating is easy to prepare and operate.

Description

technical field [0001] The invention relates to a magnetic control pigment and a preparation method thereof, in particular to a nano magnetic control pigment and a magnetic control coating containing the nano magnetic control pigment and its preparation method, which is a kind of nano magnetic material in the coating field. applied research. Background technique [0002] As we all know, in order to obtain a bright color appearance on the surface of various wood products, glass, and metal products, various coatings need to be sprayed to achieve anti-corrosion protection and better coating effects. At present, the addition and use of various pigments in coatings endow the coating with certain properties such as color, hiding power, UV resistance, corrosion resistance and metallic flash, thereby improving the decorative effect and application effect of the coating. However, it is limited to the single color of the coating film of various pigments, and the color distribution is...
