Technical solution is used by the utility model solves its technical problem：Coating structure, it is characterised in that：In tank body Outer surface be followed successively by anti-corrosion bottom, polyurethane coating hard bubble insulating layer, closure interface layer, smooth transition zone, net from the inside to the outside Lattice enhancement layer, flexible interpenetrating confining bed and heat-reflecting layer.The structure of the storage tank heat insulating coat of the utility model meets structure coating Flexible gradual change discharges the principle of stress, has preferable system cracking resistance, the heat preservation framework layer of cold insulation performance.

The thickness of the anti-corrosion bottom is 38 ~ 43 microns, and the material of anti-corrosion bottom is cashew nut oil modified amine asphalt mixtures modified by epoxy resin Fat.Anti-corrosion primary coat employs a kind of cashew nut oil modified amine epoxy resin, solves epoxy anticorrosive coating material（It is particularly thick to apply When）Flexibility is poor, and adhesive force is low, it is impossible in the technical barrier of moist surface construction, while improve the antiseptic property of coating.

The thickness of the polyurethane coating hard bubble insulating layer is 4.3 ~ 4.8 centimetres.Spray hard-foam polyurethane thermal insulation material It is a kind of larger material of plastic deformation amount, the extraneous deformability of its resistance is strong, in the works such as external force and temperature deformation, dry and wet deformation Under, crack is not susceptible to, is effectively guaranteed stability, the durability of system.

The thickness of the closure interface layer is 0.8 ~ 1.2 millimeter, the material of closure interface layer for high molecular polymer with Inorganic gel mixing material.Deformation with other layers is adapted, and sealing effect is good, ensures that internal layer will not be oxidized aging.

The thickness of the smooth transition zone is 1.4 ~ 1.7 centimetres, and hollow material is embedded on the smooth transition zone. After smooth excessive layer containing hollow material is compounded in polyurethane foam hard bubble insulation layer surface, it can not only play and look for well Flat effect, can also play a protective role to hard-foam polyurethane foam heat-insulation layer, make up in-situ spraying polyurethane foam heat insulation material In the deficiency of part, heat bridge is avoided to generate, enhance system heat insulation effect.

The thickness of the flexible interpenetrating confining bed is 1.8 ~ 2.2 millimeters.Flexible interpenetrating confining bed principal security heat reflection The adhesive force of layer.

The thickness of the heat-reflecting layer is 50 microns.Heat-reflecting layer can reflect light and partial heat, reduce internal The heat-insulated load of material.

Compared with prior art, advantageous effect possessed by a kind of heat insulating coat structure of the utility model is：This practicality The extraneous deformability of spraying hard-foam polyurethane thermal insulation material resistance that new polyurethane spraying hard bubble insulating layer uses is strong, in external force Under the effects that temperature deformation, dry and wet deformation, crack is not susceptible to, is effectively guaranteed stability, the durability of system.It is smooth Transition zone contains hollow material, after being compounded in polyurethane foam hard bubble insulation layer surface, can not only play good levelling work With can also play a protective role to hard-foam polyurethane foam heat-insulation layer, make up in-situ spraying polyurethane foam heat insulation material in office The deficiency at portion position, avoids heat bridge from generating, and enhances system heat insulation effect.The structure of this storage tank heat insulating coat meets structure coating Flexible gradual change discharges the principle of stress, has preferable system cracking resistance, the heat preservation framework layer of cold insulation performance.
