Abstract

The present invention relates to a marine heavy anticorrosive coating material, which comprises two components A and B, wherein the component A comprises the following raw materials by mass: 25-35% of a resin, 6-11% of an Al slurry, 6-9 % of a solvent, 45-55% of a filler, 1-4% of a pigment, 0.3-1% of a defoamer, 1-4% of a thixotropic agent, 0.5-2% of a thickener and 0.1-0.6 % of a coupling agent, and the component B comprises, by mass, 35-60% of a curing agent, and 40-65% of a solvent. According to the present invention, during the use, the components A and B are stirred and mixed according to a certain ratio, aging is performed, and the obtained mixture is repeatedly sprayed on a steel plate being subjected to surface sand blasting treatment in an air spraying manner until the required coating thickness is achieved; and the coating material has advantages of simple preparation process, high corrosion resistance and good anti-settling property, and the obtained coating has metallic luster and strong adhesion.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a marine heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] Corrosion, especially metal corrosion, is costly. According to incomplete statistics, the loss caused by corrosion in industrialized countries accounts for about 4% of the total output value of their national economy every year. In recent years, countries have found that the anti-corrosion of shipping ships is particularly important while vigorously developing the marine economy. The strength of the ship structure brings great damage to the ship. When the corrosion of various machinery and outfitting equipment on a ship reaches a certain level, these equipment will not work and operate normally, and various mechanical failures will occur. In severe cases, the ship will lose control during navigation and lose its self-rescue ability , resulting in serious m...
