Multifunctional coating for centralized area of electrical equipment and preparation method thereof

Abstract

The invention relates to a multifunctional coating for a centralized area of electrical equipment. The multifunctional coating comprises the following components in parts by mass: 0.03-20 part of a wave-absorbing material, 10-30 parts of diatomite, 0-40 parts of aggregate, 30-100 parts of a thickening and water-retaining agent, 3-5 parts of reinforcing fibers, 0.01-3 parts of nano platinum powder,0.1-3 parts of conductive micro powder, 24-35 parts of white cement, 10-12.5 parts of rubber powder and 10-12.5 parts of a PVB adhesive. The multifunctional coating is a nano titanium dioxide loadedhigh-purity hexagonal boron nitride / graphene nano composite material. The multifunctional coating disclosed by the invention has good capability of absorbing / shielding electromagnetic waves radiated in the environment, can purify air in a place and avoid concentration accumulation of toxic gas, has an anti-corrosion effect on a metal enclosure or a wall surface, is easy to brush and construct, hasstrong adhesive force, and is very suitable for being used on an indoor wall or an enclosure surface of an electrical equipment centralized area; the environment of a working area is improved, and the current enterprise production concept of SHE (safe and healthy environment) is met.

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
