Problems solved by technology

[0002] There are many organisms in the ocean that attach to the bottom of ships and marine underwater equipment. These attached organisms are extremely harmful to ships and marine underwater facilities. They significantly increase the weight of the hull, increase navigation resistance, affect the speed of the ship, and increase fuel consumption.
Antifouling coatings use mercury, arsenic and other compounds as poisonous materials, which pollute the marine environment seriously, seriously affect the growth and reproduction of marine organisms, and even cause genetic variation

Embodiment Construction

[0022] A kind of antifouling coating of the present invention, described antifouling coating is made up of following composition by weight percentage,

[0023] Tin-free drag-reducing high polymer 30%-50%

[0024] Poison 20%-40%

[0025] Auxiliary base material 2%-5%

[0026] Pigment 5%-10%

[0027] Solvent 10%-20%

[0028] Auxiliary 4%-7%

[0029] Wherein, the polyacrylic resin is used as the base material in the non-tin-free drag-reducing high polymer.

[0030] The poisonous material is composed of one or more of cuprous oxide, copper powder, and low-toxic organic antifouling agent. In this embodiment, copper powder is selected, and the copper powder is non-toxic to the human body during the production and coating process.

[0031] The auxiliary base material is composed of one or more of rosin, asphalt and chlorinated rubber. In this embodiment, rosin is selected.

[0032] The pigment is zinc oxide or talcum powder. In this embodiment, talcum powder is used, which can ...

Abstract

The invention discloses an antifouling paint which is characterized by comprising the following components by weight percent: 30% to 50% of drag-reducing polymer without containing stannum, 20% to 40% of toxic materials, 2% to 5% of auxiliary base materials, 5% to 10% of pigments, 10% to 20% of solvent and 4% to 7% of an addition agent. The antifouling paint is low in toxic content and can not damage the marine environment. When the antifouling paint is matched with an anti-rusting paint, the good physical property of a ship body is achieved. A paint film formed by the antifouling paint is smooth and flat, good in drag-reducing property and uniform in abrasive corrosion rate and realizes energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to an antifouling paint. Background technique [0002] There are many organisms in the ocean that attach to the bottom of ships and marine underwater equipment. These attached organisms are extremely harmful to ships and marine underwater facilities. They significantly increase the weight of the hull, increase navigation resistance, affect ship speed, and increase fuel consumption. Antifouling coatings use mercury, arsenic and other compounds as poisonous materials, which pollute the marine environment seriously, seriously affect the growth and reproduction of marine organisms, and even cause genetic variation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antifouling paint which has the characteristics of long-term antifouling, resistance reduction and energy saving, and meets the requirements of environmental protection. [0004] In order to solve the above tec...
