Abstract

The invention belongs to the technical field of marine organism fouling protection, and particularly relates to a hyperbranched amphiphilic antifouling active agent based on hydrosilylation reaction and a preparation method of the hyperbranched amphiphilic antifouling active agent. The preparation method comprises the following steps: carrying out a compound combination reaction on hydrogen-containing silicone oil and one or more of active double-bond polyethylene glycol, active double-bond fluoroalkane or active double-bond glycidyl ester to obtain a plurality of hyperbranched materials, and regulating the hyperbranched structures, surface microstructures, surface chemical properties, release rates and the like of the materials to prepare the antifouling active agent with coupled antifouling properties. Based on the characteristics of the material and the synergistic effect of multiple antifouling characteristics, the adhesion of non-specific proteins is reduced through surface microphase separation and surface chemical characteristics, the formation of conditional membranes and the effective adhesion area and adhesion strength of subsequent adhesion organisms are prevented, and the static antifouling performance is improved; the material body and surface characteristics are used for preventing fouling, cuprous oxide is not used, destructive influence on the marine ecological environment is avoided, and the antifouling period can reach 5 years or above.

Description

Technical field: [0001] The invention belongs to the technical field of marine biological fouling protection, and in particular relates to a hyperbranched amphiphilic antifouling active agent based on hydrosilylation reaction and a preparation method thereof. Friendliness and long-lasting antifouling properties. Background technique: [0002] Marine biofouling refers to the process in which molecules or organisms in the ocean accumulate and grow on the surface of structures immersed in the ocean. Once it occurs, it will affect the original function of the surface of the structure. Whether it is from the perspective of maintaining the reliability of marine equipment or the stability of marine ecosystems, the development of marine antifouling coatings is a necessary choice. Marine antifouling coatings have experienced a development process from toxic to environmental protection, short-term to long-term. There are mainly three types of antifouling coatings in the prior art: o...
