Problems solved by technology

[0002] The world has entered the information age, and the information revolution has brought great benefits to human beings. However, the negative electromagnetic radiation pollution has just been recognized by people. The treatment of electromagnetic wave pollution is a high-tech and emerging industry. At present, electromagnetic radiation pollution protective coatings are extremely rare in the market and economical. With development and population growth, a large number of household appliances and wireless communication equipment have entered the family, and the man-made electromagnetic energy in urban space is increasing every year. Electromagnetic radiation is colorless, tasteless, and invisible, and can penetrate various substances including the human body. A variety of indoor household appliances and common communication equipment are internal factors that cause electromagnetic radiation pollution. The facts tell us that from the perspective of the entire living environment, electromagnetic radiation pollution from a wider range has an unavoidable impact on the safety of indoor spaces. In reality, electromagnetic radiation pollution sources mainly come from large public facilities such as high-voltage cables, substations, microwave communication stations, and radar stations, together with indoor household appliances, communication equipment, computers, and wireless routers. healthy

Embodiment Construction

[0006] The production process of the electromagnetic wave absorbing coating of the present invention consists of the following steps: (1) The first preparation is made of graphite powder, acetylene carbon powder, silicon carbide powder, 50% of the main material, and 50% of the auxiliary material diffusing agent, ammonia and pure water. raw material.

[0007] ⑵Use a vibration mill to pretreat the first raw material for 5-10 hours.

[0008] ⑶Use a ball mill to make the second raw material with 50% of the first raw material, film-forming agent and cement, and add it to the pre-treated first raw material for emulsification.

[0009] ⑷Sieving to remove impurities, filling into the plastic bag in the packaging barrel, and sealing the plastic bag.

[0010] ⑸In packaging barrels of different weights, carbonyl silicon-coated iron powder is packaged in airtight plastic bags according to different weights, and then sealed in packaging barrels.

[0011] In this production process, according to use...

Abstract

The invention relates to an electromagnetic wave absorbing coating material, which is characterized by comprising, by weight, 25-35% of an electromagnetic wave absorbing functional powder main material, and auxiliary materials, wherein the auxiliary materials comprise 0.4-1.1% of a diffusion agent, 5-15% of a cementing agent, 8-14% of a film forming agent, 0.4-0.9% of ammonia water, and 34-61% of pure water, the components are completely mixed, the obtained mixture is added to a ball mill, uniform dispersion and material discharge are performed, detection, adjusting and screening are performed, and the electromagnetic wave absorbing functional powder main material selects the mixture of carbonyl silicon coated iron powder, graphite powder, acetylene carbon powder and silicon carbide powder. According to the present invention, the principle that the heat energy is converted from the electromagnetic energy is used, the purification difficult problem that the shielding material can not solve the whole electromagnetic radiation environment pollution can be solved, and the interference and the damage of the electromagnetic radiation on the surrounding equipment and personnel can be effectively prevented.

Description

Technical field [0001] The invention relates to the field of electromagnetic radiation pollution protection and treatment, in particular to an electromagnetic wave absorbing paint and its production process. Background technique [0002] The world has entered the information age. The information revolution has brought huge benefits to mankind.
