Domestic graphene coatings force, end the high-end anti-corrosion market without "national goods" situation

A bucket of high-end heavy-duty anti-corrosion coating that resists heavy corrosion from the ocean, from raw material formulation to large-scale production, requires a good process line and synergy in all aspects. When a certain industrial chain changes, it will lead to a chain reaction in the entire industry.

When the international coating giants such as Akzo Nobel, Sherwin-William and Kansai Paint announced the full price increase of coating products, China's import cost in the field of heavy-duty coatings gradually increased. There are indications that since 2018, the global paint price hike caused by the rising prices of raw materials has continued and has not weakened. Why is China's heavy anti-corrosion field so dependent on imports, and where is the way out for domestic brands?

Cross-border entry into the market

According to the statistics of the National Bureau of Statistics, the average annual growth rate of China's coatings industry's total output value is about 6.5%. By 2020, the total output value of China's coatings industry is expected to increase to about 560 billion yuan, and the total output is expected to increase to about 22 million tons. At present, the market size of China National Defense Coatings is second only to architectural coatings.

Although China has such a huge market economy, it is difficult to hide the embarrassing situation that the domestic coatings market is monopolized by foreign giants. It is understood that foreign coating giants account for more than 80% of China's coatings market, taking heavy-duty anti-corrosion coatings for ships and marine engineering as examples, Akzo Nobel, PPG, Haihong elderly, Jordan, Japan's Zhongtu, Japan's Kansai, etc. Foreign companies have divided more than 80% of the market share. It can be said that foreign companies have established a Chinese shopping mall that does not belong to China at all in the heavy anti-corrosion coating market for ship coatings, container coatings, offshore equipment and marine port equipment.

Long-term foreign paint giants grasp the key resources of heavy-duty anti-corrosion coatings, just like prey, they are caught in the throat at any time. Why is China's heavy-duty anti-corrosion market repeatedly “snapped neck”? The monopoly of anti-corrosion coating market has made Chinese coatings companies face the predicament of heavy anti-corrosion technology. The practitioners of heavy anti-corrosion industry know that China lacks independent innovation in high-end heavy anti-corrosion. The ability to be monopolized by foreign countries is a time bomb.

As the monopoly of China's coatings industry needs to be broken in time, a group of Chinese high-tech enterprises that are not convinced have begun to get involved in the field of anti-corrosion coatings. For example, Zhuhai Polycarbon Composite Materials Co., Ltd., a giant in the field of graphene applications, as a new graphene Materials research and development enterprises, as well as cross-borders in the field of anti-corrosion, will develop graphene heavy-duty anti-corrosion coatings as one of their development strategies. They hope to combine graphene and heavy-duty anti-corrosion coatings with their core technologies in the field of graphene to achieve Foreign paint giants have resisted courtesy, allowing domestic companies to regain market dominance.

The combination of graphene and heavy anti-corrosion coatings impacts the monopoly pattern of foreign giants

As a new type of nanomaterial, graphene has good corrosion resistance, electrical conductivity and high strength, ultra-thin and ultra-large specific surface area. These powerful physical properties can improve the anti-corrosion effect of anti-corrosion coatings, reduce the production cost of anti-corrosion coatings, and promote graphene to become an important raw material for driving technological innovation in the coatings industry.

Through the professional testing of many coating authorities, graphene can prolong the time of corrosion and the intrusion path of erosive substances, improve the adhesion of coatings and the quality of coating protective film, in flexibility test, impact test and most important resistance. Excellent properties have been demonstrated in the corrosion test, and graphene is undoubtedly the most ideal material for heavy-duty coatings. The successful application of graphene in heavy-duty coatings will greatly reduce the economic losses caused by corrosion.

In the previously published "2018 Graphene Technology Patent Analysis Report", China has ranked first in the technology original country in terms of the number of graphene technology patents, and its number of patents has been significantly ahead of other countries and regions, ranking first in the world, occupying the world. A global share of 66.5%. This is mainly benefited from the strong support of the Chinese government on the eve of the industrialization of graphene. Many special programs have greatly promoted the research and development speed of China in the field of graphene technology, and also brought an opportunity for the change of China's heavy anti-corrosion coating pattern.

In the field of heavy anti-corrosion, graphene is regarded as a well-deserved "savior", but for many years, the major topic of graphene heavy-duty anti-corrosion coating has not been broken. However, the fire of hope is being illuminated, and the key core technologies of graphene anticorrosive coatings are being broken one by one. Domestic graphene anticorrosive coatings have gradually matured, and related technology research and practical applications have continued to fall. Graphene anticorrosive coatings have continuously entered the society and the vision of major enterprises. Under the severe test of the domestic market, domestic graphene enterprises and domestic paint manufacturers have developed tacit technical research and development and supporting production activities.

In the first half of this year, Zhuhai Polycarbon Composite Materials Co., Ltd., a leading company in the graphene application industry, and Jiangmen Jiabaoli Chemical Group Co., Ltd., one of the largest coating solutions providers in China, reached a cooperation on the graphene anticorrosive primer project. I believe that in the future, China's heavy anti-corrosion field will be able to catch up, get back the market share of China's heavy-duty anti-corrosion enterprises, and be able to compete with other high-end brands in the international market.

Graphene application giant breaks through the problem of cathodic protection technology

According to the Global Graphene Strategy Research Institute, China's graphene anticorrosive coatings market will reach 500 million yuan in 2018. In 2020, the penetration rate of China's graphene heavy-duty anticorrosive coatings in industrial anticorrosive coatings will exceed 1%, reaching 3 billion. By 2022, China's graphene anticorrosive coatings market will reach 4.8 billion yuan, and graphene heavy-duty anti-corrosion coatings are expected to help domestic heavy-duty anti-corrosion coatings to enter the international high-end market.

In order to solve the key technical problems in the application of graphene heavy-duty anti-corrosion coatings, Zhuhai Polycarbon Composite Materials Co., Ltd. relies on years of research on deep ploughing of graphene and a number of patented graphene technologies, through continuous technological breakthroughs and thousands of experimental developments. The introduction of graphene oily and waterborne series of heavy-duty anticorrosive coatings, focusing on the technical problems of graphene protection for metal surfaces, creatively solved the core problem of heavy anti-corrosion coatings with short life and poor weatherability in complex marine corrosive environments.

Chen Xiaogang, Chairman of Polycarbon Composites Co., Ltd. pointed out: "Compared with traditional heavy-duty anti-corrosion coatings, graphene heavy-duty anti-corrosion coatings have significant improvement in anti-corrosion effect, and are also incomprehensible in environmental protection and low-cost mass production. Advantage". The graphene heavy-duty anti-corrosion coating developed by Polycarbon has broken the salt-tolerant limit of 800-1000 hours of traditional epoxy-rich zinc under the test standards of GB/T1771-2007 and GB/T 1766-2008. Up to 3600 hours (according to the test data, the salt spray resistance time of the composite coating composed of graphene anticorrosive primer, intermediate paint and topcoat can exceed 9000 hours), and the key process formula has independent intellectual property rights and master core technology. At the same time, the low-cost stable amount of graphene heavy-duty anti-corrosion coating is realized.

The introduction of graphene heavy-duty anti-corrosion coatings has aroused a lot of attention in the society, including the giants of the petrochemical industry, the attention of PetroChina, Sinopec and CNOOC. In the in-depth communication and negotiation with these petrochemical industry giants, CNOOC Limited has determined the graphene anticorrosive coatings developed by polycarbons, and the graphene anticorrosive coatings will be the first to be applied in the coating of large steel structures of CNOOC Zhuhai Natural Gas Power Generation Co., Ltd.

Chen Xiaogang said: "As a member of the graphene industry, we urgently hope that graphene technology can be applied to marine corrosion. We hope to protect the safety of the country's major marine infrastructure through the mastery of graphene heavy-duty anti-corrosion technology. The national economy is suffering from corrosion. This cooperation with CNOOC has meant that the anti-corrosion effect of the new anti-corrosion coating for graphene has been recognized. Polycarbon has the ability to rewrite the existing heavy-duty anti-corrosion coating market. In the anti-corrosion coating layout, we will be more confident to meet the challenge."

With the "One Belt and One Road " and the development of the international strategic layout of the maritime powers, the strategic focus of China's development is further tilted toward the sea, the national strategic interests are rapidly expanding toward the sea, and the strategic situation facing the ocean is undergoing complex and profound changes. Anti-corrosion of marine equipment is also facing new challenges. Graphene heavy-duty anti-corrosion technology will become more and more strategic for the national economic construction and the development of blue industry. In the future, more environmentally-friendly anti-corrosion coatings will be developed, and the technology will continue to update. In order to promote the development of the marine blue industry, Chinese enterprises must constantly develop and innovate, let the pace of innovation keep up with the pace of development, while protecting marine engineering and obtaining marine resources, don't forget to protect this beautiful ocean.
