Problems solved by technology

[0004] It is well known that the electrostatic conductive coating is a functional coating with the ability to conduct current and eliminate accumulated charges. The electrostatic conductive coating used in petrochemical storage tanks is to avoid accidents such as explosions and fires caused by the accumulation of charges. With the application of electrostatic conductive coatings , petrochemical storage tanks have the problem of corrosion and perforation, and the requirements for both electrical conductivity and anti-corrosion are put forward for the electrostatic conductive coating. The effect puts doubts on the range of surface resistivity of conductive coatings, and it is believed that corrosion will still occur if the resistivity is low, and it will be revised in the relevant standards, from 10 5 ~10 9 Ω is changed to 10 8 ~10 11 Ω, while the surface resistivity of conductive coatings reported in many patents and literature is in the range of 10 5 ~10 9 Ω

Abstract

The invention provides a heatproof oil-resistant phenolic epoxy static anticorrosive paint and a preparation method thereof, belonging to the field of paints. The paint comprises a component A and a component B. The component A comprises, by mass, 15 to 21% of a phenolic epoxy resin, 2 to 8% of a modified resin, 0.1 to 0.3% of an antifoaming agent, 0.2 to 0.5% of a coupling agent, 0.5 to 0.7% of a thixotropic agent, 12 to 17% of conductive mica powder, 7 to 12% of ferrophosphorous powder, 1 to 5% of titanium dioxide, 10 to 17% of talcum powder, 12 to 18% of feldspar powder and 15 to 20% of a solvent. The component B comprises, by mass, 65 to 75% of a curing agent and 25 to 35% of a solvent. The paint has effectively improved heat resistance and can resist a temperature as high as 200 DEG C; the paint has an excellent anticorrosive effect and excellent tolerance to acid, alkali, salt, oil and chemicals and is capable of enhancing an anti-rust effect and effectively reducing cost while providing conductive performance.
