Super-weatherproof heavy-duty high-solid thermal insulating electrostatic conducting coating system

Abstract

The invention discloses a super-weatherproof heavy-duty high-solid thermal insulating electrostatic conducting coating system and belongs to the technical field of chemical coatings. The super-weatherproof heavy-duty high-solid heat conductance barrier electrostatic coating system comprises a bottom coat, an intermediate coat and a surface coat, wherein the bottom coat is formed by coating an epoxy zinc rich primer, the intermediate coat is formed by coating an epoxy mica iron oxide paint and the surface coat is formed by coating a fluoro-carbon finish; the fluoro-carbon finish is added with hollow glass micro beads and a heat conducting powder. The electrostatic coating system provided by the invention is excellent in heavy duty, heat insulation and weather-proofing properties, high in electrostatic conductivity, high in solid content, low in volatilization, healthy and has environment-friendly effect, is long in system service life, and suitable for various steel structure facilities such as a gasoline can, a container, a steel pipe, a bridge, petrochemical equipment, a ship and a harbor facility.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a super-weather-resistant, heavy-duty, anti-corrosion, high-solid, heat-insulating, and static-conductive coating system. Background technique [0002] With the progress and development of society, the development of protective coatings and coating technology pays more attention to the comprehensive balance of "environmental protection, safety, performance and cost". In the field of petrochemical equipment, light oil has a low flash point. If static electricity is generated on the metal surface of gasoline tanks in high temperature days, it is easy to cause fire or explosion accidents. The usual method is to condense the gasoline tanks with circulating cooling water, but The disadvantage is that it accelerates the corrosion of the metal, and the corrosion of the metal surface will also endanger the safety of the equipment. Moreover, the metal surface coatings currently...

[0003] Chinese patent application CN101899257A discloses a heavy-duty anti-corrosion heat-insulating and static-conductive paint, which is a solvent-based epoxy paint mixed with two components of acrylic modified epoxy resin and cashew nut oil modified amine curing agent, wherein poly The aniline conductive substance makes the coating have a certain conductivity, and hollow microspheres are also added to make it have a certain heat insulation function. However, because the epoxy resin contains aromatic ether bonds, the paint film is easily degraded and broken after being irradiated by ultraviolet rays, so Poor outdoor weather resistance

[0004] Chinese patent application CN101585992A discloses a heat-insulating reflective anti-corrosion coating, which adds infrared ceramic powder and hollow microspheres to play a role in heat insulation. In addition, Chinese patent application CN103013241A also discloses a fluorocarbon nano-solar heat-insulating reflective coating And preparation method, it adopts nano Ti02 and hollow microspheres to come heat insulation and reflection sunlight, but these two kinds of coatings all do not possess static electricity conducting property
