Hǎi huà yuàn shímò xī túliào yánjiū qǔdé guānjiàn jìnzhǎn 16/5000 Key progress in research on graphene coatings in Haihua Institute

Graphene is a hot star in the material industry in recent years, and is regarded as the "king of new materials" by the industry. Haihua Institute has been conducting research on the application of graphene in coatings for more than two years. It has cooperated with many enterprises and institutions specializing in graphene research to carry out anti-corrosion coatings, water-based coatings, wind-electric coatings, anti-skid coatings, etc. Applied research and achieved a number of key technological advances.

According to the experts of the research group, the coating with added graphene is lighter and thinner, and the anti-corrosion performance and weather resistance are greatly improved. Among them, the graphene anticorrosive coating used to replace the epoxy zinc-rich primer has a salt spray time in key indicators. It has at least doubled the product index specified by the national standard and its proportion is lower than 70% of the epoxy zinc-rich primer. This product has broad application prospects in the fields of shipbuilding, marine engineering and aviation; excellent electrical conductivity using graphene Sexuality and transparency, the introduction of graphene electromagnetic wave coatings has also solved some of the technical problems, can basically meet the stringent needs of customers, enter the application verification stage.

 It is understood that China's research on graphene as a major resource of graphite has started relatively late, but it has developed rapidly. The overall situation is close to the advanced level of foreign countries, and it has mastered independent intellectual property rights in some fields. At the World Mobile Congress held in Shanghai on June 29th, the Graphene Exhibition Hall was the highlight of the conference and was followed by CCTV, Science and Technology Daily and Hong Kong Dagongwenhui. The graphene heavy-duty anti-corrosion coating developed by Haihua Institute was unveiled at the exhibition. The real model of product and corrosion inspection has aroused the interest of media, institutional investors and professional audiences, and has also been recognized by industry experts.

According to statistics, the cost of graphene processing in China has dropped to one-tenth of that in 2011, and the excellent rate and consistency have also been greatly improved. The downstream application is on a large scale. "Made in China 2025" clarifies the key position of graphene in China's strategic frontier materials; in November 2015, the United Nations Development and Reform Commission of the Ministry of Industry and Information Technology and the Ministry of Science and Technology issued "Several Opinions on Accelerating the Innovation and Development of Graphene Industry" also pointed out that graphene In China, the material is in a critical period from laboratory to industrialization. It is necessary to turn the graphene industry into a leading industry and gradually realize the industrial application of the material in some industrial products and consumer goods. By 2020, a perfect graphite will be formed. Aene industry system.

Following the market trend and grasping the opportunity of policy support, Haihua Institute will continue to conduct in-depth application research in the fields of anti-corrosion functional coatings, water-based coatings and solvent-free coatings on the basis of the experimental results already obtained. At the same time, it is engaged in basic research. Professional scientific research institutions cooperate to jointly study the anti-corrosion mechanism of graphene coatings, and use the advantages of the company's applied research to achieve strong alliances, to further broaden its application in the field of coatings and to create theoretical conditions for the improvement of industrial systems.
