as a new two-dimensional nanomaterial, graphene has important application prospects in the field of heavy anti-corrosion coatings. Although graphene-based heavy anti-corrosion coatings have been focused on by the relevant industries in recent years, they have not yet realized their large-scale practical application. The main reasons are: so far has not formed a perfect coating system, lack of comprehensive performance assessment and actual long-term service assessment, lack of detailed special database and related coating standards, graphene costs are relatively high.
In response to the common technical problems in the application of graphene-based heavy anti-corrosion coatings, the research team, in collaboration with Liu Zhaoping and Ningbo Moxi Technology Co., Ltd., has developed a special graphene composite powder and slurry for heavy anti-corrosion, focusing on breaking through the composite technology of graphene and other functional micron fillers. In cooperation with coating production enterprises and anti-corrosion engineering construction enterprises, through the coating system, creatively solve the major problems of rust coating and the core problem of long-life weather resistance of the marine coupling environment, developed a key process formula with independent intellectual property rights, and realized the low-cost and stable mass production of graphene-based heavy anti-corrosion coatings.
In order to meet the needs of different applications, Ningbo Materials Institute has successfully developed a series of graphene (white graphene) base coastal oil storage tank heavy anti-corrosion coatings, electrostatic anti-corrosion coatings, power grid tower anti-corrosion coatings, photovoltaic tower anti-corrosion coatings, seawater anti-corrosion coatings and aerospace defense special coatings, such as 8 series of anti-corrosion and
wear-resistant coatings
. Graphene-based heavy corrosion-resistant coatings have passed 5000 hours of salt spray testing, 2000 hours of resistance to 5% H2SO4 and 2000 hours of resistance to 5% NaCl immersion and other third-party testing tests.
In view of the current storage stability of graphene-based heavy anti-corrosion coating system, engineering construction process performance, coating stability and other issues that have not yet been fully verified by engineering applications, Ningbo Materials Institute of the United Nations power grid Ningbo Electric Power Company and Zhejiang Hai salt power supply company on large-scale transmission towers and substation facilities, for the "Belt and Road" high humidity environment transmission and transformation infrastructure long-term safe operation of the foundation.
In the construction of special database, the team undersefined the special task of the national material environmental corrosion platform, took the lead in the construction of the "graphene environmental corrosion thematic database", mainly through indoor accelerated damage testing and application demonstration accumulation of graphene coating in the marine atmosphere environment experimental data and environmental damage data, for graphene coatings in related fields to promote the application of extension and standard-setting data support and scientific basis to promote the development of new materials technology and theory of graphene surface protection in China.
