    Recently, at the summit meeting of high-performance graphene anti-corrosion coatings group standards, experts from the Chinese Academy of Sciences, China Coatings Industry Association, etc.
    , commented on the "Epoxy Graphene Zinc Powder Primer" and "Waterborne Graphene Electromagnetic Shielding Architectural Coatings".
    Group standards for graphene coatings were discussed

    .


    In recent years, because graphene has a large specific surface area, excellent hydrophobicity, electrical conductivity, thermal conductivity and chemical stability, and as the basic structural unit of carbon crystal materials (carbon nanotubes, fullerenes, C60, expandable graphite), graphene’s Anti-corrosion performance and the development of graphene-based composite coating materials have become the focus of research in the field of metal protection worldwide

    .
     

      Sun Lianying, president of the China Coatings Industry Association, said that the formulation of standards for graphene coatings not only fills the gaps in the country, but also promotes the scientific development of related coatings in China, which is important for the technological innovation and product structure transformation of the coatings industry in China, and the supply-side structure.
    Reform is of great significance

    .
     

      "Graphene, as an emerging functional material, can form a stable conductive grid and effectively increase the utilization rate of zinc powder
    .
    Moreover, it is beneficial to extend the recoating period in the anti-corrosion application process and effectively reduce resource waste and environmental pollution.
    , In line with the strategic requirements of green development

    .
    " Sun Lianying said

    .
     

      According to incomplete statistics, China's annual economic losses caused by the corrosion of metal materials are relatively large
    .
    In 2014, China's corrosion loss was 2.
    1 trillion yuan, accounting for 3.
    34% of the national economic output value

    .
    At present, 66% of China's anti-corrosion is through coatings

    .
    Graphene can significantly improve the anti-corrosion performance of coatings and has a good protective effect on substrate materials.
    In recent years, it has attracted great attention from the coating industry

    .
     

    At the same time, due to the introduction of graphene technology, the use of heavy metals in traditional anti-corrosion technologies has been greatly reduced, which has an inestimable effect on reducing costs, enhancing product market competitiveness, and protecting the environment
    .
     

      At present, Zhuhai Polycarbon Composites Co.
    , Ltd.
    , which has been deeply involved in the graphene industry, is one of the few in the world that can achieve large-scale production of graphene powder at a cost generally accepted by the industry, and truly achieve "zero emission" graphene production and application research and development.
    Business

    .
    It has successfully developed the first generation of graphene zinc-rich heavy-duty anti-corrosion coatings and began to carry out technical certification, and its performance indicators have also reached the basic requirements of new coatings, making polycarbon composites lead the graphene anti-corrosion technology

    .
     

      Zhuhai Polycarbonate uses a convenient and simple super-dispersion technology, directly in the coating solvent system through the three-in-one method of ultra-high-speed shearing, homogenization, stirring and the composite technology of ultrasonic after homogenization to uniformly disperse the graphene, perfect Realize the good compatibility of graphene in coatings
