Abstract

The invention discloses a magnetic bronze powder preparation method. The method comprises the following steps: cleaning sheet bronze powder ball-milled in a ball mill in a cleaning tank with a ketone solvent, press-filtering, and carrying out solid-liquid separation to obtain a filter cake; adding the filter cake, an alcoholic solvent and a titanate coupling agent to a reaction container, and stirring; taking ammonia water and distilled water, and mixing ammonia water with distilled water for dilution; taking ethyl orthosilicate, and diluting with the alcoholic solvent; simultaneously adding to the reaction container in a dropwise manner; ageing for 6-10h, taking out, press-filtering, and carrying out solid-liquid separation to obtain inorganic silicon coated bronze powder; taking the inorganic silicon coated bronze powder and an ether solvent, and uniformly dispersing the inorganic silicon coated bronze powder in the ether solvent; and taking an acrylate monomer and an azo initiator, adding to the reactor, coating, taking out, press-filtering, and carrying out solid-liquid separation to obtain magnetic bronze powder. The method allows the surfaces of the sheet copper-zinc particles to be coated with the surface of a magnetic material through organic-inorganic double layer coating, so the aqueous copper-zinc particles are magnetic, and a very good stereo artistic effect is formed.

Description

technical field [0001] The invention relates to a preparation method of magnetic copper-gold powder. Background technique [0002] In recent years, with the continuous deepening of my country's economic reform, people's living standards have been significantly improved, and they have a deeper understanding and higher requirements for the quality of life.
