Problems solved by technology

Marine antifouling paint is a common coating. The existing marine antifouling paint has the following shortcomings and defects due to the unreasonable composition formula: 1. It contains a large amount of organotin and DDT, which has a great impact on the environment; 2. Antifouling paint The pollution time is short and the effect is not good; 3. The filter layer is thick and it is difficult to clean; 4. The surface roughness is large, which affects navigation to a certain extent; 5. Bacteria are easy to breed

Embodiment 1

[0022] Take 11 parts by mass of hydrolyzed modified acrylic resin and put it into a mixing tank for medium-speed stirring at a stirring speed of 600 rpm, and stir for about 5 minutes; take 0.1 parts by mass of dispersant 5040, add it to the stirring tank for stirring, and then add 1 part by mass of Superfine iron oxide red, 5 parts by mass of zinc oxide, 0.6 parts by mass of bentonite, 22 parts by mass of cuprous oxide, 8 parts by mass of barium sulfate, 8 parts by mass of talc, 1 part by mass of zinc zinc, stirred at high speed for about 20 minutes, and stirred The rotating speed is 1000 revs / min to obtain the slurry; the slurry is moved to a grinder for grinding, and the particle size of the slurry after grinding is less than or equal to 40 microns, so as to effectively reduce the roughness after the film formation of the present invention, and the slurry is controlled during the grinding process. The temperature does not exceed 55°C; add 1 mass part of chlorinated rubber and...

Embodiment 2

[0024] Take 13 parts by mass of hydrolyzed modified acrylic resin and put it into a mixing tank for medium-speed stirring at a stirring speed of 700 rpm, and stir for about 5 minutes; take 0.2 parts by mass of dispersant 5040, add it to the stirring tank for stirring, and then add 2 parts by mass of Superfine red iron oxide, 7 parts by mass of zinc oxide, 0.8 parts by mass of bentonite, 25 parts by mass of cuprous oxide, 10 parts by mass of barium sulfate, 10 parts by mass of talcum powder, 3 parts by mass of zinc zinc, stirred at high speed for about 20 minutes, and stirred The rotating speed is 1100 revs / min to obtain the slurry; the slurry is moved to a grinder for grinding, and the particle size of the slurry after grinding is less than or equal to 40 microns, so as to effectively reduce the roughness after the film formation of the present invention, and the slurry is controlled during the grinding process. The temperature does not exceed 55°C; 3 parts by mass of chlorinat...

Embodiment 3

[0026] Take 13 parts by mass of hydrolyzed modified acrylic resin and put it into a mixing tank for medium-speed stirring at a stirring speed of 800 rpm, and stir for about 5 minutes; take 0.3 parts by mass of dispersant 5040, add it to the stirring tank for stirring, and then add 3 parts by mass of Superfine red iron oxide, 10 parts by mass of zinc oxide, 1.2 parts by mass of bentonite, 28 parts by mass of cuprous oxide, 12 parts by mass of barium sulfate, 12 parts by mass of talcum powder, 5 parts by mass of zinc zinc, stir at high speed for about 20 minutes, stir The rotating speed is 1200 rpm to obtain the slurry; the slurry is moved to a grinder for grinding, and the particle size of the slurry after grinding is less than or equal to 40 microns, so as to effectively reduce the roughness after the film formation of the present invention, which is conducive to the stable penetration of the poisonous material. During the grinding process, the temperature of the slurry is cont...

Abstract

The invention relates to the technical field of coatings and in particular relates to a hydrolyzed marine antifouling paint and a preparation method thereof. The antifouling paint comprises the following components in parts by weight: 1-5 parts of chlorinated rubber, 12-16 parts of xylene, 21-25 parts of hydrolyzed modified acrylic resin, 1-3 parts of chlorinated paraffin, 1-3 parts of superfine iron oxide red, 5-10 parts of zinc oxide, 0.6-1.2 parts of bentonite, 22-28 parts of cuprous oxide, 8-12 parts of barium sulfate, 8-12 parts of talcum powder, 1-5 parts of zineb and 0.1-0.3 part of dispersing agent 5040. The antifouling paint has the beneficial effects that the chlorinated rubber and the hydrolyzed modified acrylic resin are film forming matters and do not contain organic tin or DDT (dichlorodiphenyltrichloroethane), thus improving the environment; superfine iron oxide red and zinc oxide are antirust pigments and have good antifouling effects; and cuprous oxide and zineb are bactericides and can prevent bacterial breeding.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a hydrolyzable marine antifouling paint and a preparation method thereof. Background technique [0002] Coatings are film-forming substances on the surface of objects, which are well known and common. Marine antifouling paint is a common coating. The existing marine antifouling paint has the following shortcomings and defects due to the unreasonable composition formula: 1. It contains a large amount of organotin and DDT, which has a great impact on the environment; 2. Antifouling paint The pollution time is short and the effect is not good; 3. The filter layer is thick and it is difficult to clean; 4. The surface roughness is large, which affects navigation to a certain extent; 5. It is easy to breed bacteria. Therefore, it is necessary to adjust the formulation of the existing marine antifouling paint. Contents of the invention [0003] The purpose of the present invention ...
