Problems solved by technology

[0006] But the technical defect that the above-mentioned patent application technology exists is: (1) the magnetic powder in the magnetic paint is used as a dispersant with water, so that its dispersibility needs to be improved. The power is large, and there is almost no magnetic power in some positions, which directly leads to poor use of magnetic coatings; (2) The above-mentioned coatings overemphasize the magnetic function of the coating, and do not consider its basic properties such as heat insulation, weight loss, and flame retardancy. , it seems that the function of the coating is too single.

Abstract

The invention discloses an interior wall paint with magnetic functions, and a preparation method thereof. The interior wall paint with magnetic functions comprises following components, by weight, 40to 50 parts of a matrix, 20 to 40 parts of a solvent, 1 to 10 parts of a weight reducing body, 3 to 6 parts of a flame retardant, 3 to 6 parts of a lubricant, and 5 to 10 parts of nanometer Fe3O4. Itis prepared through four steps including preparation of a nanometer Fe3O4 dispersion, matrix pre-curing, wet coating preparation, and wet coating curing. Compared with the prior art, the advantages are that: the interior wall paint possesses strong magnetic force; the lubricant capable of improving touch feel is adopted, so that excellent comfortability is achieved; the interior wall paint possesses thermal insulation function, is non-toxic, is safe, is friendly to the environment, and is a novel functional coating with both the advantages of magnetic coating and common coating; and no pollution is caused.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an interior wall coating with magnetic function and a preparation method thereof. Background technique [0002] Magnetodynamic function refers to the collective name of biomagnetic function, negative ion generation function, far-infrared ray emission function, and antibacterial function; as we all know, magnetism is electricity, electricity is magnetism, and the two are inseparable; as far as electricity is concerned, it contains electromagnetic waves, and electromagnetic waves It also contains visible light and invisible light. Therefore, magnetic power contains the energy of magnetism, electricity, light and heat. [0003] Studies have found that reasonable magnetic stimulation can improve and improve the body's ability to resist and treat diseases. As a natural physical energy, magnetism may maintain the "magnetic balance" between the human body and the environment through its effects...
