Problems solved by technology

Therefore, it will also affect the growth of beneficial marine organisms while using it, and it will also cause certain pollution to seawater.
[0004] Traditional marine antifouling paints have the following defects depending on the type: For example, a layer of gray-green or black sediment will be formed on the surface of the paint film in the later stage of the dissolved antifouling paint, which is insoluble cuprous sulfide
The other is called hydrolyzed antifouling paint, also called self-polishing antifouling

Embodiment 1

[0026] (1) prepare 63% coal tar pitch liquid: break up above-mentioned 3 kilograms of coal tar pitch and put into the container with agitator, then add No. 200 coal tar of 5 kilograms, infiltration process, fully stir and dissolve then, Make 8 kilograms of 62.5% coal tar pitch liquid, standby;

[0027] (2) Preparation of mixed solvent: 10 kilograms of toluene, 9 kilograms of xylene, 3 kilograms of butyl acetate and 3 kilograms of ethanol are added in a reactor with a stirrer, mixed and stirred to make a mixed solvent in the reactor spare;

[0028] (3) Dissolving composite base material: Grinding 20 kg of rosin into fine powder and 2 kg of phenolic resin into fine powder, adding them to the above reaction kettle respectively, then adding 2 kg of powdered chlorinated rubber and 1 kg of powdered HCPE ; Fully stir in the mixed solution in the reactor until fully dissolved;

[0029] (4) Mixed coal tar pitch: the 62.5% coal tar pitch liquid prepared in the above-mentioned (1) step...

Abstract

An anti-fouling paint composition for ship is prepared from high-molecular polymer (28-36 pts.wt.), composite toxic material (25-36.6 pts.wt.), colour filler (22-32 pts.wt.), toughening agent (3.5-5 pts.wt.), sagging inhibitor (2-3 pts.wt.) and mixed solvent (30-38 pts.wt.) through mixing, stirring and dissolving. Its advantage is long service life.

Description

technical field [0001] The invention relates to a ship antifouling technology, in particular to an antifouling paint which is suitable for the parts below the waterline of the ship and can effectively prevent the ship from being polluted by marine organisms. The present invention also relates to a method for preparing the above antifouling paint. Background technique [0002] When a ship sails on the ocean or anchors in a port, the bottom of the ship and the parts below the waterline are always immersed in seawater, and fixed offshore oil drilling platforms and other fixed offshore facilities are also immersed in seawater all year round. It will be attached and corroded by marine organisms living in seawater such as barnacles, oysters, sea squirts, limeworms, screwworms, wood-boring water lice and seaweed. The attached ship will increase the weight of the hull, increase the surface roughness of the hull, increase the resistance, and slow down the speed, which also increases...
