Magnetism-absorbing coating and preparation method thereof

Abstract

The invention relates to a magnetism-absorbing coating and a preparation method thereof. The magnetism-absorbing coating comprises 20-70 percent of emulsion, 10-80 percent of ferromagnetic powder of non-magnetite powder and non-iron scurf powder, 0.1-10 percent of preservative and rest percent of water which are all mixed uniformly according to a certain proportion. The coating has no original magnetism, does not influence peripheral electronic products, but utilizes the ferromagnetic powder or a ferromagnetic compound to be diffused to an aqueous or unctuous coating basal body coated on a wall body, and the coating basal body is coated on the surface of an object or the wall body to generate a large-area magnetism-absorbing surface so that blueprints, pictures or notices, and the like can be hung on the wall by stationery magnets. The coating has extremely wide applications, can be coated on the surfaces of glass, wood, wall bodies, cloth, ceramics, plastics, paper, and the like to generate the magnetism-absorbing surfaces and facilitate the suspension of notes, catalogues, and the like. The invention also has the waterproof function and can be applied outdoors.

Description

technical field [0001] The invention relates to a stationery building decoration material, in particular to a magnetic-absorbing paint and a preparation method thereof. Background technique [0002] With the improvement of living standards and the advancement of science and technology, people have higher and higher requirements for wall decoration, and the materials for wall decoration are constantly being updated to meet people's needs, and the quality of wall decoration is also constantly changing. With the improvement of the improvement, the color and texture of the walls decorated with various decoration materials are getting better and better, but if you want to hang drawings, paintings, announcements and other items or decorations on the decorated walls, people usually have to hang them on the walls. Put nails on the surface, or fix it with glue, or put iron sheets on the wall, and fix it with magnet adsorption, which will destroy the beauty of the wall and give people...

AI Technical Summary

Problems solved by technology

Using this construction method will destroy the wall surface, and the construction is difficult. After the wall surface is painted with putty containing magnetite powder, the wall surface will be magnetic, which will affect the surrounding electronic products.
