A kind of multifunctional coating used in the concentrated area of ​​electrical equipment and its preparation method

Abstract

The present invention relates to a multifunctional paint used in concentrated areas of electrical equipment, which comprises: 0.03-20 parts by mass of wave-absorbing material, 10-30 parts by mass of diatomite, 0-40 parts by mass of aggregate, 30-20 parts by mass of 100 parts by mass of thickening and water-retaining agent, 3-5 parts by mass of reinforcing fibers, 0.01-3 parts by mass of nano-platinum powder, 0.1-3 parts by mass of conductive micropowder, 24-35 parts by mass of white cement, 10-12.5 parts by mass The rubber powder of part, the PVB adhesive of 10-12.5 mass parts; Described wave-absorbing material is nano-titanium dioxide supported high-purity hexagonal boron nitride / graphene nanocomposite material. The multifunctional coating of the present invention has a good ability to absorb / shield electromagnetic waves in the environment, can purify the air in the place, avoid the accumulation of toxic gas concentration, and has anti-corrosion effects on metal casings or walls, and is easy to paint and construct. Strong, very suitable for use on indoor walls or casing surfaces in areas where electrical equipment is concentrated, to improve the environment of the work area, in line with the current SHE (Safety, Health and Environment) enterprise production concept.

Description

technical field [0001] The invention belongs to the field of functional coatings, and relates to a multifunctional coating used in areas where electrical equipment is concentrated and a preparation method thereof. Background technique [0002] With the operation of new infrastructure projects such as UHV power transmission and the in-depth construction of 5G, more and more related components such as electrical equipment have been put into actual production applications. In areas where large electrical equipment is concentrated, the environment is relatively poor, which poses a potential threat to the health of personnel who work in this environment for a long time. It mainly includes the following factors: First, large electrical equipment, including power supply equipment, servers, and wireless signal transceiver equipment, will generate complex electromagnetic signals, which will have thermal, non-thermal, and cumulative effects on human body functions. Thermal effect: It...

Third, medium and high voltage electrical switching is easy to produce nitrogen oxides. Nitrogen oxides have varying degrees of toxicity and can irritate the lungs, making it difficult for people to resist respiratory diseases such as colds. People with respiratory problems such as asthma Sick people are more susceptible to the effects of nitrogen dioxide
