Marine heavy-duty anti-corrosion coating and preparation method thereof

Abstract

The invention discloses a heavy-duty anti-corrosion coating for ships and a preparation method thereof. The coating is prepared from a component A and a component B, wherein the component A is prepared from the following components in part by weight: 42 to 55 parts of epoxy resin, 2 to 6 parts of tributyl phosphate, 0.1 to 0.5 part of graphene, 2 to 6 parts of aluminium triphosphate, 1.2 to 2.2 parts of modified nano zinc oxide, 5 to 9 parts of organic bentonite, 5 to 9 parts of montmorillonoid, 5 to 9 parts of talcum powder, 0 to 2 parts of pigments, 8 to 13 parts of diluent, 0.3 to 1.2 partsof anti-foaming agents, 0.3 to 1.2 parts of dispersing agents, 0.3 to 1.2 parts of leveling agents, 0.1 to 1.1 parts of coupling agents, 0.3 to 1.2 parts of film-forming assistants and 28 to 38 partsof solvents; the component B is prepared from the following components in parts by weight: 20 to 40 parts of curing agents and 20 to 30 parts of solvents. The coating disclosed by the invention has the advantages of excellent corrosion resistance, penetration resistance, weathering resistance, mechanical performance, abrasion resistance, antibacterial property and adhesive force; the preparationmethod is simple and feasible.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to marine heavy-duty anti-corrosion coatings and a preparation method thereof. Background technique [0002] The ocean plays an increasingly important role in the economic construction and security of all countries, and the rational use and development of marine resources has become the common goal of cooperation and development of all countries. At present, it has gradually developed and formed a multi-level marine regional economy based on coastal tourism, fishery, port and transportation, and offshore oil and gas industry. More than 80% of international trade is carried out through ocean transportation. Natural resources, so the development and use of the ocean has extremely broad prospects and significance. But seawater is a moderately strong electrolyte solution, where O 2 and Cl - Ships, offshore platforms and equipment used in the marine environment are in ...

AI Technical Summary

Problems solved by technology

However, the coating simply uses zinc powder as a protective means, and it is easy to generate zinc oxide mist during the welding process, which has toxic and side effects on operators.
