Abstract

The invention discloses an oil storage tank thermal insulation coating which comprises a thermal insulation intermediate layer and thermal insulation finish, and is characterized in that hollow microspheres with different meshes are selected in the thermal insulation intermediate layer and thermal insulation finish and are respectively matched with body fillers of different particle sizes so as to form a hollow isolating layer to reflect infrared radiation in sunshine; the hollow microsphere comprises the main components of SiO2 and Al2O3 and is in a shape of a standard sphere. According to the coating, infrared radiation (mainly a heat source) in sunshine or the absorbed heat energy is radiated to the outer space through pigment and filler particles in the coatings, so that the surface temperature of the coated object is reduced, and a thermal insulation effect is achieved. The coating has the heat reflectivity of more than or equal to 85 percent, and the heat conductivity coefficient is less than or equal to 0.076k / m*k. The oil storage tank thermal insulation coating is suitable for thermal insulation protection of the surfaces of oil pipelines, storage tanks and roofs.

Description

technical field [0001] The invention relates to a heat-insulating reflective paint, in particular to a heat-insulated paint for petroleum storage tanks, which is mainly used to reflect infrared radiation in sunlight or radiate absorbed heat to the external space. Background technique [0002] At present, the technical defects of domestic petroleum storage tank coatings are mainly: the film-forming hardness of alkyd resin paint and epoxy ester resin paint is low, the corrosion resistance is poor, and its salt spray resistance can only reach more than 100 hours; It is poor in acid and alkali resistance, weather resistance and decoration, and has poor thermal insulation protection performance for oil storage tanks, pipelines, petrochemical containers, containers, roofs and other surfaces. Contents of the invention [0003] The object of the present invention is to provide a thermal insulation coating for petroleum storage tanks, which uses hollow microspheres and reflective ...
