Abstract

The invention belongs to the technical field of metal corrosion protection, and relates to a synergistic antifouling material based on microstructures and antifouling active substances and a preparation method thereof. The material is composed of matrixes formed by a plurality of microstructure base units with circular shaft structures, wherein the internal lower layer of each microstructure base unit is filled with an antifouling active substance, and the internal upper layer of the microstructure base unit is filled with a sealant. The process of the preparation method comprises steps of preparing microstructures, preparing the liquid antifouling active substances and preparing the synergistic antifouling material, and adhesion of fouling organisms is prevented through synergistic anti-fouling effect of the microstructures and the anti-fouling active substances. Components of the synergistic antifouling material are simple in structure, the material contains no nitrite, phosphate or heavy metals, and metal corrosion protection and inhibition effects on bacterial growth are good; the material is environment-friendly and safe, is a novel antifouling material based on new principles and new technologies because of adoption of surface microstructure properties and the anti-fouling active substances for synergistic fouling prevention, and has good promotion and application prospects.

Description

Technical field: [0001] The invention belongs to the technical field of marine antifouling materials, in particular to a synergistic antifouling material with a microstructure and an antifouling active substance and a preparation method thereof, in which a ring-shaped surface microstructure and a releasable antifouling active substance are synergistically formed in the ocean In the environment, antifouling is carried out to prevent and eliminate biofouling on the surface of ships and marine structures. Background technique: [0002] Marine fouling including microorganisms, marine plants, and marine animals The phenomenon that organisms adhere to and grow on the surface of marine structures and adversely affect marine structures is called marine biofouling. Marine structures plagued by marine biofouling include ships , docks, docks, oil platforms, submarine cables, buoys, power plant cooling pipes, fishing nets, etc. Marine structures have long been attacked by common fouling...

AI Technical Summary

Problems solved by technology

Therefore, constructing a special surface is an important way to develop new antifouling materials and technologies. As we all know, the antifouling agent release layer on the surface of the coating material can significantly inhibit the fouling organisms, but with the dissolution, hydrolysis, polishing, etc. of the coating As a result, the saponification layer thickens, the antifouling agent release layer gradually changes, and the concentration of antifouling agent gradually decreases with time, until it is difficult to reach the concentration that inhibits fouling organisms. This is the limited existence of antifouling agent coatings. The main reason for the period of use

On the other hand, the microstructure of the solid surface can also affect the attachment and desorption behaviors of bacteria, algae spores and invertebrate larvae. Materials with microstructures are usually organosilicon systems, which basically do not dissolve or hydrolyze in seawater. Therefore, it has relatively long-term stability, but due to the presence of organic matter and inorganic particles in natural seawater, the surface microstructure will be filled after a period of immersion and lose its antifouling effect
