[0074] Pigment 4

[0075] surface smoother 2

Embodiment 2

[0077] This embodiment is the coating process and effect of Embodiment 1.

[0078] The surface of the hull is iron, pre-surface treated. The base material and the curing agent are mixed and then sprayed with an air spray gun, and repaired locally by hand. After the coating is completed, dry it at room temperature for 12 hours before launching into the water. The test results are as follows.

Abstract

The invention discloses an anti-absorption environmental-protection ship coating, composed of basal material and curing agent, and its main components include polysiloxane, antifouling compound, releasing agent, polyamine, all of them are nontoxic and able to be oxidatively decomposed or biodegradable in the environment, the coated surface energy is low, the coating surface is smooth, and the resistance is small as the ship navigating, once paint film can meet the thickness requirement and the coating is durable and has completely good wearability; dry-film surface is extremely smooth so that marine organisms cannot absorb firmly and simultaneously has anti-absorption effect on bacteria.

Description

technical field [0001] The invention belongs to the field of ship coating, and more specifically relates to a ship coating, especially an anti-adsorption environmental protection coating for marine ships. Background technique [0002] Ocean ships are the largest cargo carriers in international trade. However, the hull of marine ships suffers from corrosion every moment when sailing in the ocean. In addition to being electrochemically corroded by seawater, it will also be adsorbed and fouled by marine organisms and microorganisms. [0003] Due to the complex chemical composition of seawater, the underwater coating of marine ships suffers from corrosion. Once the hull steel plate loses the protection of the coating and is exposed to seawater, the corrosion is very serious. The annual average corrosion rate of high-quality hull steel plate in seawater is about 0.1mm . [0004] Another type of corrosion comes from marine life. When the underwater part of the hull is attached...
