Problems solved by technology

[0002] Existing anti-corrosion coatings mainly use solvent-based epoxy resins, and some use silicone resins as film-forming substances, adding pigments, anti-rust pigments, fillers, additives, organic solvents, etc., relying on physical adhesion, long-term high temperature resistance and corrosion resistance Poor, requires frequent maintenance, and after the equipment is finalized, it cannot be maintained and painted, so there are unreasonable formulas; at the same time, the product contains organic solvents such as xylene, which pollutes the environment and is not environmentally friendly
[0003] For the anti-corrosion coating of the flue, due to the high temperature of the air flow and the strong corrosive sulfides, nitrides, and solid particles, the existing anti-corrosion coatings use silicone resin, which dries slowly (surface dry 1h, hard dry 24h, fully cured Rely on high temperature curing), poor adhesion (physical combination), not resistant to high temperature (only about 200 degrees), not resistant to sulfide, nitride corrosion, low hardness of the coating and not resistant to wear, resulting in the use of the flue Severe corrosion and frequent maintenance

Abstract

The invention provides a sulfur-containing flue anticorrosion paint with strong stability, corrosion resistance and environmental friendliness and a preparation method of the sulfur-containing flue anticorrosion paint. The sulfur-containing flue anticorrosion paint comprises inorganic polymer, nano silicon dioxide, nano titanium dioxide, quartz powder, silicon carbide, graphite powder and high-temperature flue ash. According to the sulfur-containing flue anticorrosion paint and the preparation method thereof, the high-temperature-resistant chemical-corrosion-resistant inorganic polymer is adopted, and nano materials, graphite powder, silicon carbide, anticorrosion pigment, high-temperature flue ash and wear-resistant materials are added, and the inorganic polymer and steel form a chemical bond, so that good adhesion, high hardness and high temperature resistance are achieved, the corrosion of sulfide and nitride and the airflow abrasion can be prevented, and a good and durable anticorrosion effect can be achieved; and zero emission of volatile organic compounds (VOC) is achieved, so that the environment is not polluted.

Description

technical field [0001] The invention relates to an anti-corrosion paint and a preparation method thereof, in particular to a sulfur-containing flue anti-corrosion paint and a preparation method thereof. Background technique [0002] Existing anti-corrosion coatings mainly use solvent-based epoxy resins, and some use silicone resins as film-forming substances, adding pigments, anti-rust pigments, fillers, additives, organic solvents, etc., relying on physical adhesion, long-term high temperature resistance and corrosion resistance It is poor and requires frequent maintenance, and after the equipment is finalized, maintenance coating cannot be carried out, so there are unreasonable parts in the formula; at the same time, the product contains organic solvents such as xylene, which pollutes the environment and is not environmentally friendly. [0003] For the anti-corrosion coating of the flue, due to the high temperature of the air flow and the strong corrosive sulfides, nitrid...
