Description

technical field [0001] The invention relates to the technical field of spraying polyurea materials, in particular to an antistatic explosion-proof polyurea material and a preparation method and application thereof. Background technique [0002] With the advancement of my country's oil reserve strategy, my country has entered a period of rapid growth in the construction of large-scale petrochemical equipment. Crude oil, especially light oil, generates electric charges due to friction during transportation, mixing, filtering, filling, and extraction. Charge accumulation occurs when the rate at which charges are exported is less than the rate at which charges are produced. When the concentration of volatile oil reaches the explosion limit, the accumulated electric charge is likely to generate static sparks and cause an explosion, resulting in huge economic and property losses. By coating the surface of the equipment with antistatic materials, the accumulation of charges can b...
