Preparation method for nano magnetic paint

Abstract

The invention relates to the field of preparation of magnetic materials, and discloses a preparation method for nano magnetic paint. The preparation method comprises the following steps of: weighing,in parts by weight, 30-60 parts of Bi2MoO6 / polyethylene glycol chitosan grafted matter / nano magnetite composite materials, 25-45 parts of filler, 20-30 parts of polyvinyl alcohol, 9-10 parts of carboxymethyl cellulose and 5-20 parts of ethyl carbamate, performing mixing and stirring, performing heating, adding 2-3 parts of deionized water, 2-5 parts of a coloring material and 3-5 parts of naturalrubber, performing stirring, and conducting cooling. The preparation method has a simple process and environmental protection, and the prepared paint has strong magnetism and a function of health care, can be in close contact with a coated interface, does not fall off easily, can adsorb pollutants in the air, can load a photocatalyst for pollutant degradation, and does not cause adsorption saturation; in addition, catalyst loading is solid, the utilization rate of light energy is high, the catalytic effect is good, and therefore the preparation method for the nano magnetic paint is suitable for practical production application.

Description

technical field [0001] The invention relates to the field of magnetic material preparation, in particular to a preparation method of nanometer magnetic coating. Background technique [0002] At present, the existing interior decoration materials contain formaldehyde, causing indoor formaldehyde and other harmful gases to exceed the standard, seriously endangering people's health and even life safety. Cause people to have many diseases, such as cancer. In recent years, diatom mud coatings have been launched in the market. The disadvantages are that on the one hand, the raw materials are scarce and the quality is uneven; [0003] Magnetic power function refers to the general term of biomagnetic function, negative ion generation function, far infrared emission function, and antibacterial function. Studies have found that reasonable magnetic stimulation can improve and improve the body's own ability to resist and treat diseases, and produce a variety of health care biological e...
