Problems solved by technology

This not only delayed the navigation mission, but also caused a huge waste of manpower and material resources
[0005] (2) After marine equipment is attached by organisms, it may change the surface characteristics of the ship's hull metal and accelerate the corrosion of the metal
Among them, algae plants produce oxygen through photosynthesis, which increases the oxygen content of the nearby water body. The carbon dioxide produced by the respiration of shellfish and the decomposition products of animal and plant decay will increase the acidity of the nearby water body. Some marine organisms will even damage the surface of the equipment. Protective coatings, which can cause corrosion of metal parts and shorten the life of the generator set
In addition, a large amount of adsorption of marine organisms will also affect the water flow and heat dissipation of the unit, reducing the operating performance and stability of power generation equipment

Abstract

The invention discloses a copper-based metal anti-biological coating which comprises a copper-based alloy wire. The copper-based alloy wire comprises the following components in percentage by weight: 50%-78% of copper, 18%-45% of zinc, 1.3%-2.5% of lead, 0.2%-1.9% of tin, 0.2%-2.6% of aluminum, 0.2%-1.3% of nickel, 0.1%-3.3% of zirconium dioxide and 0.1%-0.8% of copper oxide. A preparation method is further included and sequentially comprises the following steps that S1, the copper-based alloy wire is pretreated; S2, a to-be-protected surface is pretreated; S3, the to-be-protected surface is polished; and S4, spraying is performed. The coating is good in wear resistance, good in biological adhesion resistance, excellent in corrosion resistance and stable in performance. Different from TBT and toxic material coating biological adhesion resistance technologies of the same type, the copper-based metal anti-biological coating belongs to an environment-friendly technology, and has an extremely small influence on the marine environment.

Description

technical field [0001] The invention belongs to the technical field of metal coatings, and in particular relates to a copper-based metal anti-biological coating and a preparation method thereof. Background technique [0002] With the depletion of terrestrial resources, including minerals, land, and organisms, the ocean and coast are also becoming the focus of countries competing to develop resources and energy. Marine equipment, such as submarines, ships, and offshore platforms, is an indispensable tool for human exploration and development of the vast ocean, so its development directly promotes the development of navigation and naval power in various countries. The marine environment is very complex and changeable, which seriously affects the performance of marine equipment, and the harm caused by marine biofouling is particularly prominent. Biofouling is actually the formation process of biological communities on the surface of marine equipment materials. In this process,...
