Abstract

The invention provides an antistatic explosion-proof polyurea material and a preparation method and application thereof. The antistatic explosion-proof polyurea material is prepared from a component Aand a component B. The component A is prepared from diisocyanate, polyester polyol and carbon nanotubes; the component B comprises the following raw materials: polyester polyol, an amino-terminated chain extender and an auxiliary agent. The antistatic explosion-proof polyurea material comprises carbon nanotubes, the carbon nanotubes have excellent mechanical properties, electrical properties, optical properties, adsorption properties and the like; a small amount of carbon nanotubes are added into the polyurea material, so that the tensile strength and tearing strength of the polyurea materialcan be improved, the mechanical properties of the material can be further improved to achieve explosion-proof and impact-resistant effects, and the surface resistivity of the polyurea material can beobviously reduced to achieve an antistatic effect.

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 generated. 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 ...
