Embodiment 1

[0082] Embodiment 1: the preparation method of the tin-free, copper-free environment-friendly marine antifouling paint of the present invention:

[0083] Slowly stir 13.3kg of xylene, 5kg of PMA (propylene glycol methyl ether acetate) and 11.3kg of rosin resin until completely dissolved, dissolve at 28°C for 50 minutes, add 6kg of chloroether resin, stir for 15 minutes, and the speed of the stirrer is 2023 rpm Then the rotating speed is adjusted to 1840 rev / min, and the powder material (soy lecithin 0.4kg, talcum powder 10kg, zinc oxide 20.6kg, iron oxide red 8kg, medium yellow 1kg, bentonite 0.7kg, antifouling agent N) is started to be added at 34°C -(2,4,6)-Trichlorophenyl (maleimide) and pyrithione copper zinc each 4.5kg), because it is too thick, add 10g of light aromatic hydrocarbon solvent in advance, add glass beads and start frosting at 26°C, speed 3870 rpm; after grinding, adjust the speed to 1800 and add the rest (plasticizer (261A) 2kg, light aromatic solvent (S100)...

Abstract

The invention provides tin-free and copper-free environment-friendly marine antifouling coating. The tin-free and copper-free environment-friendly marine antifouling coating is prepared from the following components according to the ratio: xylol, PMA (Polymethyl Acrylate), rosin resin, chlorinated polyether resin, soybean lecithin, talcum powder, zinc oxide, ferric oxide red, medium yellow, bentonite, an antifouling agent, a plasticizer and a light aromatic solvent. The tin-free and copper-free environment-friendly marine antifouling coating provided by the invention particularly still has an obvious antifouling effect under a static state of a ship, and has tin-free and copper-free properties; the tin-free and copper-free environment-friendly marine antifouling coating has no pollution to the sea; the antifouling coating also has a large biological species inhibition range and the releasing speed of the antifouling agent is stable; the antifouling coating has the characteristics that the antifouling coating is not easy to precipitate, the service life is long and the like; the navigational speed of the ship is indirectly increased and fuel oil is saved.

Description

technical field [0001] The invention belongs to the technical field of marine coatings, and in particular relates to a tin-free and copper-free environment-friendly marine antifouling coating, a preparation method and a coating method. Background technique [0002] When a ship sails for a long time, especially when it stays in a port or anchorage for a long time, the part of the hull surface immersed in water below the waterline, especially the bottom surface of the ship will rust due to long-term immersion in water, and grow seaweed and other plants, barnacles, Animals such as tube worms and shellfish, plankton and non-biological species, such as mixtures of organic and inorganic debris. And the phenomenon that continuously causes the hull and bottom surface of the underwater part to be dirty and rough is called fouling, commonly known as "long hair". Ship fouling (marine attachments) is extremely harmful, and the existence of fouling is an important factor affecting ship ...
