A systematic laboratory study on an anticorrosive cool coating of oil storage tanks for evaporation loss control and energy conservation

• The anticorrosive cool coating consists of three functional layers.
• The anticorrosive cool coating has high solar reflectance and thermal emittance.
• The coating has good cooling effects and low thermal conductivity.
• The coating has good resistance to dirt, weather, chemical and salt spray.
• The presence of saline coupling agents greatly improves the adhesion of the coating.

The composition and manufacturing process of a three-layer anticorrosive cool coating for oil storage tanks are introduced. The optical, indoor thermal and physicochemical properties were systematically investigated. In addition, the outdoor cooling effect and the reduction of evaporation losses of crude oil were predicted. The coating developed has high solar reflectance and thermal emittance and thus good indoor and outdoor temperature reduction effects. The unique structural design and the careful selection of ingredients endow the coating with low thermal conductivity and good resistance to dirt, weather, salt spray and chemicals. The selected epoxy functional saline couple agent creates a chemical bridge between the coating's binder and the surface of carbon steel substrates and improves the adhesion of the coating.
