Abstract

The invention discloses an anti-corrosion coating for a ship shell. The coating is prepared from the following raw materials in parts by weight: 53-60 parts of chloroprene rubber, 5-8 parts of para-tertiary butyl phenol formaldehyde resin, 6-10 parts of perchloro-ethylene resin, 10-14 parts of di-tributyl stannic oxide, 10-13 parts of titanium dioxide, 7-11 parts of rosin, 11-16 parts of tricresyl phosphate, 26-30 parts of methyl isobutyl ketone, 25-30 parts of methylbenzene, 5-7 parts of silane coupling agent, 3-7 parts of zinc oxide, 8-11 parts of red lead, 3-6 parts of ferric oxide, 10-14 parts of a thixotropic agent, 9-11 parts of auxiliary filler and 10-14 parts of anti-corrosion filler. According to the coating provided by the invention, the problems that the conventional coating is low in underwater attachment property, the coating layer is easy to fall off and the corrosion resistance is low are solved; the cost-to-performance ratio is greatly increased; moreover, the coating disclosed by the invention is high in underwater coating attachment capacity, high in corrosion resistance, high in impact strength and high in flexibility.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating for ship hulls. Background technique [0002] The marine environment is a very harsh corrosive environment. Marine corrosion refers to the corrosion of metal components in the marine environment. The marine environment is a complex corrosive environment. In this environment, seawater itself is a strong corrosive medium. At the same time, waves, waves, tides, and currents produce low-frequency reciprocating forces and impacts on metal components, and marine microorganisms, attached organisms, and their metabolites are all harmful to Corrosion processes produce direct or indirect accelerations. Marine corrosion is mainly localized corrosion, which occurs in a small area starting from the constructed surface. In addition, there are low-frequency corrosion fatigue, stress corrosion and microbial corrosion. Generally, the general corrosion rate of metal compon...
