Description
Technical Field
The invention belongs to the technical field of anticorrosive coatings, and particularly relates to a high-adhesion nano anticorrosive heat-preservation integrated coating and a preparation method thereof.
Background
At present, the technical level of heat preservation implemented by a large number of pipelines and thermodynamic equipment in the petroleum and petrochemical industry is uneven, and the heat preservation is directly related to energy production construction, cost and environmental protection. Due to the fact that the using conditions are poor, the polyurethane foam jacket pipe and rock wool materials which are widely used at present are serious in thermal aging, high in heat conductivity coefficient and poor in heat preservation effect, and accordingly the maintenance cost is increased. Meanwhile, the heat insulation material replaced after aging belongs to solid waste, needs additional harmless treatment, and increases the treatment cost. The polyurethane foam jacket pipe and the rock wool have no anticorrosion function and need to be matched with heavy anticorrosive paint for use. Most heavy anticorrosive paints can be coated only after the anticorrosive area needs to be finely polished before construction, and the construction process is relatively complicated.
CN113121871A, CN109321058A, CN108410302A all disclose the preparation of an anticorrosive heat-insulating coating, but no rust conversion agent is introduced, so that the function of converting red rust into black rust cannot be realized, and construction with rust cannot be realized. In addition, although the porous structure of the ceramic heat-insulating coating has a low heat conductivity coefficient and a good heat-insulating effect, the ceramic heat-insulating coating is physically isolated, heavy-duty primer or finish paint is required for secondary coating, the integrated functions of corrosion resistance and heat insulation cannot be realized, and the construction is extremely inconvenient.
CN111423792A discloses an anticorrosive heat-insulating nano water-based integrated coating, and the resin used is organic silicon modified resin. Although the silicone resin coating has the outstanding advantages of excellent high and low temperature resistance, weather resistance, chemical resistance, wear resistance and the like, the application range of the silicone resin coating is limited by the defects of low strength, low adhesion with a substrate and the like. CN111423792A also mentions that extra acrylic resin needs to be coated on the surface of the coating to improve the water resistance, secondary construction is carried out, and the construction process is relatively complicated. The neutral salt spray test result is less than 2000 hours. CN 113980524A discloses an anticorrosion and heat preservation integrated material and a preparation method thereof, wherein fluorine-silicon modified acrylic acid is mainly used as a base material, weather resistance needs to be further improved, a rust conversion function cannot be effectively realized for a long time by a method of directly adding a rust conversion agent, and the result of a neutral salt spray test is less than 2000 hours.
