A biomimetic marine antifouling coating

Abstract

The invention discloses a bionic marine antifouling paint which comprises the following raw materials in parts by weight: 30-45 parts of fluorinated acrylic ester, 20-35 parts of silicone rubber, 2-10 parts of biological antifouling agent, 15-25 parts of filler, 0.5-1 part of organic bentonite, 0.5-1 part of polyethylene wax and 2-7 parts of propylene glycol. According to the bionic marine antifouling paint disclosed by the invention, P-cinnamate sulfate in the biological antifouling agent has a remarkably strong attachment inhibiting effect on marine bacteria and barnacle; homarine can prevent attachment of marine benthic diatom and barnacle; diterpene formamide has a function of inhibiting barnacle and shellfish larvae; the rubber silicon material and fluorinated acrylic ester material have extremely low surface free energy, low friction coefficient, high hydrophobicity and high contamination release performance, so that attachments are not easily attached or are insecurely attached.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to a bionic marine antifouling paint, which belongs to the technical field of paint. Background technique [0002] The adhesion of marine organisms brings great harm to ships and marine facilities. On the one hand, these marine organisms adhere to the surface of artificial facilities in the sea, which will increase the ship's navigation resistance, block pipelines and breeding nets, and affect the normal operation of acoustic instruments and other offshore equipment. Use, increase the burden of offshore oil and gas exploration platforms, accelerate metal corrosion and other serious hazards, resulting in huge losses in marine military activities, marine transportation, industry and aquaculture production. [0003] Since the development of antifouling coatings in the early 20th century, the problem of marine organisms has been basically solved. After the 1970s, with the prohibition of antifoul...

Problems solved by technology

After the 1970s, with the prohibition of antifouling agents such as mercury and arsenic, organotin compounds became representative antifouling agents. However, in the 1980s, it was discovered that organotin accumulated in fish and shellfish, which led to genetic pollution in aquatic animals. The variation was serious, so organotin antifouling agents were banned, and in 2008, organotin antifouling agents were completely banned

At present, cuprous chloride antifouling agent coatings occupy a dominant position in the field of antifouling, but because copper elements will accumulate in large quantities in the ocean, especially in harbors, causing a large number of algae to die, thereby destroying the ecological balance of the marine environment, so will eventually be disabled
