Problems solved by technology

However, although the existing marine coatings can avoid the erosion of seawater and the atmosphere, the hardness of the coating formed after coating is relatively poor. After long-term use, it is easy to cause wear and damage to the surface coating of the hull.

Abstract

The invention relates to the field of coatings and specifically relates to an oil paint for ships and a production method thereof. The oil paint for ships comprises the following raw materials in parts by weight: 80-120 parts of epoxy resin, 50-70 parts of acrylic resin, 20-30 parts of titanium dioxide, 15-20 parts of nanometer iron oxide, 15-20 parts of nanometer titanium oxide, 18-20 parts of barite, 5-10 parts of modified hydrogenated castor oil, 3-5 parts of perlite, 2-3 parts of de-foaming agent, 1-1.5 parts of dispersing agent, 0.8-1 part of anti-settling agent and 0.5-1 part of thickening agent. The prepared oil paint for ships is capable of avoiding seawater corrosion and atmospheric corrosion and has high hardness, high resistance to corrosion, stable use effect, excellent water and oil repellent, antifouling property and corrosion resistance; the oil paint is unlike to attach to the marine organisms, and thus is harmless to the marine organisms and is suitable for the operating environment of ships; the oil paint is capable of resisting against seawater impact, is unlike to blister and fall off after long-term soaking in water and has excellent corrosion resistance; the antifouling and rustproof effects are excellent.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to a marine paint and a production method thereof. Background technique [0002] 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 stress and impact on metal components. In addition, marine microorganisms, attached organisms and their metabolites are all harmful The corrosion process produces direct or indirect acceleration. Marine corrosion is mainly local corrosion, that is, corrosion that occurs in a small area from the surface of the component, such as galvanic corrosion, pitting corrosion, and crevice corrosion. [0003] In the marine environment, when an object is immersed in seawater, its surface first undergoes micro-fouling, that is, micro-organisms such as bacteria attach to the surface of the object, and grow and reproduce o...
