Problems solved by technology

Organotins can achieve broad-spectrum and high-efficiency antifouling purposes at low concentrations, but because these substances are stable and accumulate in water, they can cause deformities in some organisms, and may enter the food chain, becoming a safety hazard that affects human health and ecology

Embodiment 1

[0018] This embodiment discloses an antifouling paint for ships, which uses Zn-Al-Mg-RE as the main agent, organic silicon or fluoride as the auxiliary agent, and cuprous oxide and auxiliary poison as the antifouling agent. The auxiliary poison is one or more of isothiazolinones, triazines, zinc and copper complexes of pyridinethiol oxide.

[0019] The preparation method of the anti-fouling paint for ships, the high-speed arc spraying technology sprays the anti-fouling paint for ships on the surface of the ship materials, and then coats the organic coating on the surface of the coating to construct a composite anti-corrosion coating.

[0020] The sample prepared with artificial defects was soaked in 5% NaCl solution for 430 hours, and it was found that the artificial pores in the organic coating were blocked by the corrosion products of the antifouling paint coating for ships, and the corrosion products in the artificial pores were further detected by SEM The microstructure is...

Abstract

The invention provides antifouling paint for ships, as well as a preparation method and an application of the antifouling paint. The antifouling paint for the ships is prepared from Zn-Al-Mg-RE as main agents, organosilicon or fluoride as an auxiliary agent as well as cuprous oxide and auxiliary toxic agents as antifouling agents, wherein the auxiliary toxic agents are one or more of isothiazolinone, triazine and zinc and copper complexes of pyridyl thiophenol oxide. The anti-fouling effect is good in the corrosive environment. High-speed arc spraying is a dynamic and non-equilibrium rapid metallurgical process. As a result of asymmetry of melting of cored wires on two electrodes, the difference in composition of a wire sheath and composition of a core, and the asynchronism of melting of the sheath and the core, the size of droplets and alloying inside the droplets are seriously non-uniform, and various forms of tissue are formed during solidification and cooling.

Description

technical field [0001] The invention relates to paint technology, in particular to an antifouling paint for ships, its preparation method and application. Background technique [0002] Marine corrosion of ships is one of the biggest factors affecting their lifespan. Structural damage and destruction due to corrosion will seriously affect the performance and safety of the ship. After marine organisms adhere to the surface of the ship, it will not only reduce the speed of the ship, reduce the maneuverability, and increase the fuel consumption; but also cause the ship, seawater desalination equipment and underwater The degree of corrosion of facilities, etc. is intensified, and the service life is significantly shortened. In order to reduce the harm of marine organisms and prevent marine organisms from fouling ships, people have studied a variety of antifouling technologies, such as electrolytic seawater antifouling, ultrasonic antifouling, biological enzyme antifouling, low s...
