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...

Problems solved by technology

[0003] At present, more in-depth research has been carried out on microstructured surface antifouling materials at home and abroad. The techniques for preparing microstructures mainly include: photolithography using electromagnetic radiation for etching, and using hard molds with microscopic patterns on the surface Physical contact patterning for pattern replication on solid surfaces, soft lithography and molecular self-assembly for microstructure replication using a stamp or mold made of polydimethylsiloxane (PDMS) with a microscopic pattern on its surface technology and organic polymer surface patterning technology; the more common surface patterning technology of organic polymers is block polymer assembly preparation microstructure technology and breathing map technology, such as Brennan's research group through lithography and soft lithography molding The method of preparing micro-nano structure anti-fouling surface, Karen L.Wooley in the United States prepared an imitation dolphin skin material with anti-fouling effect by resin blending two polymers with micro-phase separation characteristics, Lenz et al. copied mussel shell Obtain microstructure antifouling materials; but the above methods are more suitable for theoretical research, and large-scale engineering applications are difficult; the synthesis of block polymers in the microstructure technology of block polymer assembly requires harsh experimental conditions and high costs ; Breathing graph technology requires humidity control components, and there are also difficulties in application in ship antifouling coatings; in summary, the existing microstructure antifouling technology generally has complex process, difficult control, small industrial application range, and antifouling. Disadvantages such as poor staining effect
