Dimension-adjustable porous micro-structured surface antifouling material

Abstract

The invention belongs to the technical field of marine life fouling prevention, and relates to a dimension-adjustable porous micro-structured surface antifouling material prepared from mixed materials of organosilicon acrylic acid copolymer resin, an amine nucleation promoter, and a curing agent according to a certain volume ratio. First, organosilicon acrylic acid copolymer resin, the amine nucleation promoter, and the curing agent are well mixed, and the mixture is used for coating, such that a dimension-adjustable porous micro-structured surface is formed under room temperature. The volumeof the amine nucleation promoter takes 0.5% to 2.0% of the volume of organosilicon acrylic acid copolymer resin, and the volume of the curing agent takes 1%-3% of the volume of organosilicon acrylic acid copolymer resin. A mass ratio of a prepolymer containing double-bond organosilicon to propylene monomers is 2:1-1:2. The content of acrylonitrile monomers takes 0-25% of a total mass of the propylene monomers. The adjusting method is advantaged in simple technology, reliable principle, convenient adjustment, and flexible operation. The material is advantaged in good antifouling effect, and issuitable to be used in equipment fouling preventing occasions in various marine environments.

Description

Technical field:

[0001] The invention belongs to the field of marine biofouling protection, and relates to an antifouling material, which is a scale-adjustable porous microstructure prepared by direct film formation and designed for preventing marine organisms attached to the surface of ships and marine structures in the marine environment. Surface anti-fouling material. Background technique:

[0002] Marine fouling organisms, also known as marine fouling organisms, refer to microorganisms, plants and animals that grow on the bottom of ships and on the surface of marine facilities. More than 600 species of fouling organisms have been recorded in my country's coastal areas, among which the main groups include algae, water weeds, external anal animals, scutellaria, bivalves, barnacles, and sea squirts. Ships and marine facilities in the marine environment will be affected by biofouling. The main hazards include increasing the resistance of the ship, blocking pipelines, accele...
