Abstract

The invention relates to the field of coatings, in particular to a heavy-duty anti-corrosion coating for underwater coating and a preparation method thereof. The coating is made of modified epoxy resin and compound curing agent as the main film-forming substance, and is made by adding pigments and fillers. The coating has high underwater bonding strength and excellent underwater brushing performance. The coating is an environmentally friendly product with low surface treatment, no floating and no decomposition in underwater construction, good leveling, good adhesion, and good drying performance. This product is suitable for the surface protection of buildings, structures, bridges, drilling platforms, piles and columns in seawater and freshwater, saving energy, shortening construction period and improving efficiency.

Description

Technical field: [0001] The invention relates to the field of coatings, in particular to a heavy-duty anti-corrosion coating for underwater coating and a preparation method thereof. Background technique: [0002] With the continuous development of offshore oil, port terminals, hydropower stations and shipbuilding industries, many engineering structures in the marine environment, such as drilling and mining equipment, drilling platforms, offshore oil and gas storage tanks, support frames for pipelines, trestles, steel piles, The bottom of the ship and the interior of the ship, etc., are submerged in seawater all the year round, or are subject to tide fluctuations and splashes, and are eroded by marine organisms and some moving objects, so that the original anti-corrosion layer of the structure is damaged, and these structures are difficult to remove. Carry out maintenance to land, and this just urgently needs a kind of coating that can directly be painted in seawater. In add...
