Suzhou greifeng has been cooperating with international well-known anti-corrosion coating enterprises and many domestic well-known enterprises with innovative power to jointly carry out the research and development of graphene zinc powder coating technology and market application technology Suzhou greifeng is the main drafting unit of the industry standard "graphene zinc powder coating" (Hg / T 5573-2019) of the Ministry of industry and information technology and the group standard "determination of graphene in coating", which is an important force to promote the application of graphene materials in the anti-corrosion coating market Figure 1 Transformation trend of szgraphene and its high-quality thin-layer graphene (GRF Series) environmentally friendly high-performance coatings: the impact of traditional coatings on the environment is mainly the emission of volatile organic compounds (VOCs) in the production and coating process With the increase of people's attention to environment and health, under the promotion of national environmental protection laws and regulations, standards, supervision, etc., various provinces and cities have developed a batch of air pollution emission standards for the coating industry In April 2019, the national development and Reform Commission issued the guidance catalogue of industrial structure adjustment At present, the water-based wood, industry, ship coating, high solid content, solvent-free, radiation curing, low VOCs content of functional exterior wall exterior insulation coating are encouraged, which are environmentally friendly and resource-saving coatings, and are used in the production of high-performance anti-corrosion coatings in key fields such as large aircraft and high-speed rail In 2020, the national standard "technical requirements for coatings with low VOC content" will be released soon, which will have a significant impact on the green transformation and structural adjustment of the coating industry The transformation of traditional coatings to environmental protection and high-performance coatings has become a new market demand and an inevitable trend of the development of coatings industry Market and technology of environmental protection high performance coatings: anticorrosive coatings are widely used in large-scale industry, marine engineering, modern transportation, petroleum and petrochemical, energy industry, municipal facilities and other fields In 2018, the production of anticorrosive coatings in China was ~ 5 million tons, and the market scale reached 120 billion yuan Foreign enterprises occupy the middle and high-end market of domestic anticorrosive coatings, and occupy 60% of the market share Domestic enterprises lack of advantages in brand, technology, scale, system supporting and other aspects, and are unable to compete with international well-known enterprises in the high-end market The use of new environmentally friendly, non-toxic and high-performance raw materials, as well as the cooperative development with innovative raw material suppliers, is an important strategy for coating enterprises to develop innovative products with market competitiveness At the same time, the new environment-friendly high-performance coating provides a new competitive market opportunity for domestic and foreign enterprises The product development and technical innovation of environment-friendly high-performance coating become the core competitiveness of the future development of coating enterprises High quality thin-layer graphene improves coating performance: high quality thin-layer graphene dispersion slurry products (GRF series, solvent dispersion type, water dispersion type) have unique technical advantages in quality and stable dispersion, with perfect crystallization quality, ultra-thin sheet structure, long-term stable dispersion ability, excluding hydroxyl (- OH), carboxyl (- COOH), epoxy group（ - CH (o) ch -) and other functional groups that are easy to cause hydrophilic or adverse reactions of the paint film, without topological defects and structural hole defects First of all, high-quality graphene thin layer provides the thinnest atomic layer barrier so far, effectively shielding a variety of corrosion media, and makes a good contribution to the compactness, mechanical strength, adhesion, inhibition of corrosion spread and other aspects of the film Secondly, in addition to improving the corrosion resistance, the UV shielding effect of the film also enhances the weather resistance of the film Third, high-quality graphene can also be conductive, anti-static, electromagnetic shielding, heat conduction, heat dissipation, sterilization and bacteriostasis, water-proof, wear-resistant and impact resistant to achieve the multi-functional role of the coating In addition, through the use of high-quality thin-layer graphene and reasonable formula design, it can also play a role in resource saving Figure 2 High quality thin-layer graphene improves many functions of environmental protection coatings Environmental protection contribution of high-quality graphene to coatings: according to the definition of the World Health Organization (who), volatile organic compounds (VOCs) are various organic compounds with boiling points of 50 ℃ to 260 ℃ at room temperature VOCs include alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketones and other classes The theoretical VOC (g / L) formula of liquid coating can be expressed as: VOC = (1-W) ´ R ´ 1000 (g / L), where W is the mass solid fraction (%), R is the density of liquid coating (g / ml) Therefore, VOC can be reduced by increasing the solid content of W, or reducing the density of liquid coating R First of all, high-quality thin-layer graphene can improve the performance of the coating and prolong the service time of the coating, so as to reduce the number of coating recoating or repair, and indirectly reduce VOCs emissions Or, through the use of high-quality graphene thin layer, improve coating performance, reduce the amount of coating, can also reduce VOCs emissions Secondly, through the use of high-quality thin-layer graphene and the adjustment of the formulation process, the filler with low density can be used to replace the filler with high density For example, the amount of zinc powder with high density in graphene zinc powder coating can be reduced by more than half compared with epoxy zinc rich coating, thus reducing VOCs Contact information:
