Photocatalysis self-cleaned amphiphilic network ocean anti-flouring coating and preparation method thereof

Abstract

The invention provides a preparation method of a photocatalysis self-cleaned amphiphilic network ocean anti-flouring coating. The preparation method is characterized by comprising the following steps: preparing an amphiphilic triblock copolymer according to an ATRP (atom-transfer radical-polymerization) method; modifying the obtained amphiphilic triblock copolymer by using an acyl halide monomer so as to obtain an amphiphilic block copolymer with unsaturated double bonds; performing ultraviolet irradiation on the amphiphilic block copolymer with unsaturated double bonds, a cross-linking agent and MPTS (methacryloxy propyl trimethoxy silane) modified nano titanium dioxide to implement a curing cross-linking reaction, so as to obtain an MPTS modified nano titanium dioxide hybridized amphiphilic copolymer network coating; sequentially putting the obtained MPTS modified nano titanium dioxide hybridized amphiphilic copolymer network coating into a trimesoyl chloride solution and a dispersing liquid of amino acid amphiphilic ion modified titanium dioxide nanoparticles, implementing reactions, and taking out, so as to obtain the photocatalysis self-cleaned amphiphilic network ocean anti-flouring coating. The photocatalysis self-cleaned amphiphilic network ocean anti-flouring coating can be applied to aspects such as ship coating and long-term anti-flouring of underwater equipment. The invention further discloses a method for preparing an amphiphilic copolymer network.

Description

technical field

[0001] The invention belongs to the field of marine antifouling polymer materials, and in particular relates to a method for preparing an antifouling coating aimed at modifying the surface of an amphiphilic network, which can be used to form a high-strength, firmly bonded, environmentally friendly and super-strong antifouling coating on the surface of ships and the like. Composite antifouling coating based on double modified nano-TiO2 for antifouling cycle. Background technique

[0002] Marine biofouling has always been a major problem restricting the development and utilization of marine resources due to the increase in ship navigation resistance and fuel consumption, accelerated hull corrosion and repair costs, biological invasion and epidemic spread, and harm to aquaculture. Using antifouling coatings, ocean shipping could reduce fuel consumption worth $60 billion and reduce greenhouse gas emissions by 3.6 million tons per year. As an important way to sol...
