Abstract

The invention discloses a heat transfer enhancing anti-corrosion coating material and a preparation method thereof. The heat transfer enhancing anti-corrosion coating material comprises the componentsin percentage by mass: 20-60% of a binder, 5-30% of a high-thermal conductivity material, 5-30% of a high-emissivity material, 2-20% of a heat-resistant anti-corrosion pigment, 0.5-5% of an additiveand 0-50% of a dispersion medium. The coating material is prepared by a special preparation method, and is better in homogenization and stable in storage. The coating material not only has excellent heat resistance, but also has a good heat transfer enhancement function; and the coating material is dense, has good corrosion resistance to the corrosive atmosphere and has good adhesion to metal substrates.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a heat exchange-enhancing anti-corrosion coating material and a preparation method thereof. Background technique [0002] The main equipment boiler of a thermal power plant is the most typical heat exchange equipment, whether it is the boiler four tubes (water wall tubes, superheater tubes, reheater tubes and economizer tubes) in the furnace part, or the air preheater tubes in the subsequent part and GGH et al. The low heat exchange efficiency and corrosion of the above-mentioned equipment or components have always been one of the direct factors affecting the safe operation of boiler units. [0003] The corrosion problems faced by the four tubes of the boiler and the air preheater are basically the same. Generally speaking, the composition of the corrosive atmosphere it faces includes sulfide, sulfate, reducing gas and chloride. After testing and research, it is foun...
