On October 29, SZXW Graphene Technology Group, the world's first national high-tech enterprise to realize the full graphene industry chain, held a new coatings release conference and announced the graphene composite ceramic corrosion-resistant resin and coatings developed by it, breaking the high-end overseas for more than 20 years Anti-corrosion coating technology is monopolized, and graphene-modified coatings have also officially entered the field of chemical anti-corrosion, opening the road of innovation for the development of modified anti-corrosion coatings in China.
60% of China's anticorrosive coatings market is occupied by foreign companies
Rusting of steel is the Achilles heel of iron. The amount of steel scrap due to corrosion accounts for about 25%-30% of the output of steel that year, causing a huge waste of resources. The premature destruction of concrete structures caused by the corrosion of steel bars and the maintenance costs caused by metal corrosion have become problems in engineering construction.
However, in the field of anti-corrosion coatings, foreign-funded enterprises and joint ventures account for 60% of the Chinese market, and heavy-duty anti-corrosion products are 80% occupied by international brands. On the other hand, with the advancement of the “Belt and Road” construction, China’s infrastructure construction industry and marine engineering have ushered in a period of vigorous development. The development of anti-corrosion coating technology has also become a national strategic development demand, and graphene modified anti-corrosion coatings are included The "13th Five-Year Plan" and the list of new materials that the Ministry of Industry and Information Technology will focus on developing.
In order to break the situation that China's heavy anti-corrosion coatings and core raw materials are heavily dependent on imports, SZXW cooperated with various professional colleges and industry research experts five years ago to organize research and development and put into production, and developed the "graphene composite ceramic corrosion-resistant coating" series. Not only has completely independent intellectual property rights, but also expanded its scope of application.
At the press conference, SZXW released a total of six products, namely graphene composite ceramic anticorrosive resin coatings, graphene modified anticorrosive coatings, graphene modified functional coatings, supporting industrial anticorrosive coatings, industrial/commercial floor paints, graphite Alkene modified powder coating.
Among them, the graphene composite ceramic corrosion-resistant resin coating is the first of SZXW in the coatings market. The coating made of this resin as the main film-forming material has an appearance similar to ceramics and can be used for extreme environmental corrosion, marine corrosion and chemical corrosion resistance. Unparalleled advantages of traditional resin coatings.
Graphene modified functional coatings break the technical bottleneck of coatings and realize the integration of anti-corrosion, thermal conductivity and insulation technologies. "In the past, anti-corrosion coating products can only paint these three functions separately. However, graphene modified functional coatings have developed graphene anti-corrosion and thermal conductive insulating paint, which can achieve one paint and three functions, and multiple protection." SZXW Industrial Materials Said Xie Xueping, deputy general manager of the business department.
Innovative technology fills the gap in the traditional anti-corrosion coating market
"Taking chemical anticorrosion as the entrance, we hope to fill the gap in the constantly updated market demand for the traditional anticorrosive coating industry, and lead graphene to the innovation road of the coating industry." Xie Xueping said that chemical anticorrosion is the highest level of anticorrosive coatings The chemical anticorrosive coatings developed by science and technology can be used in conventional coatings as well as in special environments. Not only can it be widely used in ships, petroleum, chemical, electric power, rail transit, energy, etc., but also in chemical storage tanks, desulfurization tower linings, and various strong chemical media, high temperature, high wear resistance and hardness. Highly demanding environment, etc.
At the same time, as the "overall graphene solution", the chemical anticorrosive coatings of Enwang Technology can serve various coating environments. For example, it can work with wet, that is, when the ship needs to be painted with a paint layer, it can be painted directly in the water without pulling it back to shore, thereby saving a lot of maintenance and repair costs.
In addition, transforming technology into large-scale production is the key to development. Due to the advance layout, Enwang Technology has now built a resin factory, anti-corrosion coating factory and powder coating production factory with an annual output of 10,000 tons. Among them, graphene modified powder coatings have achieved large-scale mass production and sales.
"This modified powder coating utilizes the characteristics of few layers of graphene to increase the powdering rate of powder coatings and improve the mechanical properties, weather resistance, corrosion resistance, flame retardancy and antibacterial properties of powder coatings. It is not only efficient, but also energy-saving. Environmental protection." Xie Xueping said that due to its superior performance, the coating has played an important role in railway system anti-corrosion coatings, communication equipment coatings, antibacterial and easy-to-clean coatings. Toyota, BMW, Amazon and other companies have reached cooperation.
It is reported that in 2019, the sales of the eco-chain of the Coating Industry Ecosystem will exceed RMB 50 million and this year is expected to exceed RMB 65 million. At present, Enwang Technology has a comprehensive layout. It has established a graphene coating operation center in the Shenzhen Group headquarters, established a number of research and development institutions across the country, and invested in the establishment of large-scale 10,000-ton coating production bases in South China and East China.
