Problems solved by technology
However, due to the harsh working environment, frequent alternation of dry and wet, and the complexity of the structure, it is difficult to clean and paint maintenance, making it one of the most severely corroded parts of the ship's cabins, and the corrosion of ballast tanks often occurs Bringing extremely serious safety hazards, which has high requirements for ship ballast tank coatings
At present, the coatings for ballast tanks of ships on the market have high solvent content, have the disadvantages of large pollution, not environmental protection, etc., and have poor wear resistance, water resistance and seawater resistance.

Embodiment Construction
[0024] The technical solution of the present invention will be described in further non-limiting detail below in conjunction with preferred embodiments.
[0025] In terms of mass percentage, the ship ballast tank coating composition of the present invention comprises the following components:
[0026] A component
[0027]
[0028] B component
[0029] Special Modified Polyamide Resin
[0030] When used, the mass mixing ratio of component A and component B is 6.25:1.
[0031] The above-mentioned dispersant is a polymer polyurethane copolymer dispersant, and the leveling agent is an acrylic leveling agent.
[0032] The preparation process of the ship's ballast tank coating composition:
[0033] 1) Put liquid epoxy resin, dispersant, titanium dioxide, carbon black and polyamide wax into a mixer, stir at high speed for more than 30 minutes, disperse until the fineness is below 25 microns, and wash in 100S;
[0034] 2) Add modified amino resin, leveling agent, talcum powder...

The invention discloses coating composition for a ballast tank of a ship. The coating composition comprises a component A and a component B in percentage by mass, wherein the component A comprises 15.0%-45.0% of liquid epoxy resin, 0.1%-0.5% of a dispersing agent, 8.0%-11.0% of titanium dioxide, 0.2%-0.8% of carbon black, 2.0%-4.5% of polyamide wax, 2.4%-4.9% of modified amino resin, 0.2%-0.8% of a flatting agent, 23.0%-26.0% of talcum powder, 12.0%-17.0% of barium sulfate, 3.0%-7.0% of silver paste, 4.0%-8.0% of solvent oil and 1.2%-2.5% of isobutyl alcohol; the component B comprises specially modified polyamide resin; and during use, the weight mixing ratio of the component A to the component B is 6.25: 1. The coating composition for the ballast tank of the ship has the advantages of low VOC (volatile organic compounds), no pollution, environment protection, good toughness, abrasion resistance and adhesive force and excellent water resistance and seawater resistance.
Description
technical field [0001] The invention belongs to the field of coatings, and in particular relates to a coating composition for a ship's ballast tank and a preparation method thereof. Background technique [0002] The ballast tank is the compartment used to hold the ballast when the ship is empty. Among the various compartments of the ship, the ship's ballast tank plays a key role in maintaining the balance and stability of the ship, which ensures the safety of the ship's navigation. However, due to the harsh working environment, frequent alternation of dry and wet, and the complexity of the structure, it is difficult to clean and paint maintenance, making it one of the most severely corroded parts of the ship's cabins, and the corrosion of ballast tanks often occurs Bringing extremely serious potential safety hazards, which has high requirements for ship ballast tank coatings. At present, the coatings for ballast tanks of ships on the market have high solvent content, have ...
