Synergistic antifouling material with microstructure and antifouling active substance and preparation method thereof

Abstract

The invention belongs to the technical field of metal corrosion protection, and relates to a synergistic antifouling material with a microstructure and an antifouling active substance and a preparation method thereof. The microstructure is composed of a matrix arrangement formed by several basic units of the microstructure in a circular well-shape structure. The inner lower layer of the basic unit is filled with an antifouling active substance, and the inner upper layer of the microstructure basic unit is filled with a sealing agent. The process of the preparation method includes three steps: preparing a microstructure, preparing a liquid antifouling active substance and preparing a synergistic antifouling material. Through the synergistic antifouling effect of microstructure and antifouling active substances, it prevents the adhesion of fouling organisms; its component structure is simple, does not contain nitrite, phosphate and heavy metals, and has good metal corrosion protection and inhibition of bacterial growth. Friendly, environmentally friendly and safe, it utilizes surface microstructural properties and antifouling active substances for synergistic antifouling. It is a new type of antifouling material based on new principles and technologies, and has good prospects for promotion and application.

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
