Abstract
The invention relates to anticorrosive paint and a preparation method thereof. The paint is prepared from, by mass, 20-70% of polybenzoxazine, 1-30% of polyamine, 1-20% of adjacent dihydroxy aromatic constituents, 1-15% of yttrium oxide, 2-6% of carnauba wax, 3-9% of talc powder, 5-15% of Mn-ZrC composite power bodies, 0.1-10% of dispersing agents, 0.1-6% of expanded perlite, 1-5% of molybdenum disulfide micro powder and 5-30% of organic solvent. The anticorrosive paint does not contain any heavy metal material, the salt fog resistance time is longer than 4200 hours, the damp heat resistance time is longer than 4200 hours, and the paint has excellent mechanical properties.
Description
technical field [0001] The invention relates to a heavy-duty anti-corrosion coating, in particular to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Heavy-duty anti-corrosion coatings refer to a class of anti-corrosion coatings that can be applied in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings. The main application areas of heavy-duty coatings are: ① Emerging marine engineering: offshore facilities, coastal and bay structures, offshore oil platforms; ② Modern transportation: highway guardrails, bridges, boats, containers, trains and railway facilities, automobiles, airports Facilities; ③Energy industry: hydraulic equipment, water tanks, petroleum refining equipment, petroleum storage equipment (oil pipes, oil tanks), power transmission and transformation equipment, nuclear power, coal mines; ④Large industrial enterprises: papermaking equipment, medical equipme...
