Abstract

The invention relates to the technical field of electronic materials, in particular to magnetic liquid metal printing ink and a preparation method thereof. The magnetic liquid metal printing ink is formed by evenly mixing liquid metal and magnetic liquid, gallium alloy serves as the liquid metal, the liquid gallium alloy can increase magnetism of the printing ink, meanwhile good conductivity of the liquid metal is maintained, the melting point of the liquid metal is increased, the magnetic liquid is mainly composed of soft magnetic nano magnetic particles, and water, organic solvent, oil or a mixture of the water, the organic solvent and the oil are added to serve as a base solution, so that the printing and forming effect is improved, and an ink material is not prone to magnetization. The magnetic liquid metal printing ink is simple in preparation method, good in formability, low in cost and has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a magnetic liquid metal printing ink and a preparation method thereof. Background technique [0002] At present, due to the current industrial development, electromagnetic fields are flooding people's lives, thus causing electromagnetic environmental pollution. Magnetic ink can absorb and shield electromagnetic waves, so that printing is more accurate. As one of the main materials of magnetic ink, soft magnetic material is a magnetic material with low coercive force and high magnetic permeability; soft magnetic material is easy to magnetize, It is also easy to demagnetize, so it has attracted widespread attention and is currently commonly used in electrical equipment and electronic equipment. However, soft magnetic nano-magnetic particles are difficult to mix with liquid metal, so it is not easy to be used in industrial production. [0003] With the development of ...
