Problems solved by technology

[0003] At present, there are two main types of conductive coatings used on oil storage tanks: one is based on carbon black or conductive carbon fiber. During use, carbon black and conductive carbon fiber are easy to be drawn out, and the oil will be polluted. At the same time, Its adhesion and anti-corrosion performance are not very ideal; the other type uses metal or metal oxide as the conductive function body. When metal or metal oxide is used as the conductive function body, the metal is easily oxidized, and its conductivity is unstable. Even if the conductive function body can meet the requirements of GB6590-2001 "Safe Static Conductivity of Light Oil Products" at the beginning, but after a short period of time, the conductive function body cannot meet the requirements of GB6590-2001 "Safe Static Conductivity of Light Oil Products". Conductivity requirements, moreover, affect metal recovery quality

Abstract

The invention discloses a carbon nanotube epoxy resin composited static conductive coating material and a fabrication method thereof. As a carbon nanotube with a special effect is adopted as a static conductive body, the carbon nanotube epoxy resin composited static conductive coating material is good in electrical conductivity; as the carbon nanotube is subjected to chemical and mechanical dispersion and complex treatment, the carbon nanotube is adaptable to an anti-corrosive paint system; a static conductive coating formed by the carbon nanotube epoxy resin composited static conductive coating material has comprehensive properties of durable oil resistance, water resistance, heat resistance, corrosion resistance, solvent resistance, no pollution to an oil product, no influence on regeneration of storage tank steel and the like; and the static conductive coating meets relevant requirements of GB6950-2001'Safe Rest Conductivity of Light Fuel Oil' in a standard exceeding manner, and is very good in stability.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a carbon nanotube epoxy resin composite electrostatic conductive coating material and a preparation method thereof. Background technique [0002] Static conductive coating material is a coating material with a wide range of applications, which can lead out the static charge accumulated on the surface of the material and eliminate static electricity. Anti-static is an important issue during the storage and transportation of petroleum products. Static conductive coating material is an effective measure for anti-static. To this end, the country has successively issued GB1338-1992 "Electrostatic Safety Regulations for Liquid Petroleum Products", GB16906-1997 "Measurement Method for the Resistivity of Static Conductive Coatings for Petroleum Storage Tanks", GB6950-2001 "Technical Indicators for Static Conductive Coatings for Petroleum Tanks", GB6590- 2001 "Safety Static Co...
