On September 27, 2020, the 2020 China New Material Innovation Technology Innovation Competition has successfully concluded.
Since the competition started in July this year, special matches and national semi-finals have been held in cities such as Xi'an and Chengdu. A total of 106 events have participated in the competition. Through online preliminary evaluation, road show and on-site defense, 16 projects stood out and successfully advanced to the national finals. The "Graphene Conductive Composite Powder" project brought by SXYY Graphene Technology Co., Ltd. has won high praise and favor from the competition review in terms of industry analysis, technology iteration, market competition, team, and scene implementation, and finally relying on outstanding performance With extraordinary strength, he won the national championship of the growth group in one fell swoop.
Project development background
Graphene is a two-dimensional crystal with a thickness of only one layer of carbon atoms exfoliated from graphite materials. As a new type of nanomaterial with the thinnest, strongest, and strongest electrical and thermal conductivity discovered so far, graphene is called "black gold" and is the "king of new materials". Scientists even predict that graphene will "completely change the 21st century". "It is very likely to set off a disruptive new technology and new industrial revolution sweeping the world.
With the in-depth development of economic globalization, social development has also brought harm to the environment. The buried oil tanks and pipelines of gas stations are buried in the ground for a long time and are vulnerable to natural disasters, corrosion of various chemicals and electrostatic accumulation. The problem, especially when corroded by water and carbon dioxide, can easily cause leakage problems after being corroded.
At present, there is an anti-corrosion and anti-static coating market with a level of hundreds of billions at home and abroad
Project technical highlights
Energy security is the lifeline of the country, especially in the recent domestic and international situations. China has begun to implement the strategy of "increasing oil reserves and ensuring energy security". At this stage, there are only a handful of companies at home and abroad that can do both anti-corrosion and electrical conductivity, and SXYY graphene conductive coatings solve this problem.
SXYY is a scientific and technological enterprise focusing on graphene research and development, focusing on the green process for batch preparation of graphene and downstream applications of graphene modified coatings. At present, there are graphene epoxy zinc-rich heavy-duty anticorrosive coatings, graphene conductive coatings, graphene internal drag reduction coatings and other products, which are widely used in petroleum pipelines, military equipment, marine anticorrosion and other fields.
Among them, the graphene conductive composite powder developed by the company is mainly used in the petroleum and petrochemical field. Through the two core technologies of graphene conductive inner wall coating and high-solid epoxy storage tank outer wall coating, the perfect unity of anti-corrosion performance and electrical conductivity can be achieved. At the same time, the salt spray test can reach 3000 hours without maintenance every 5 years.
According to the project speaker Tian Youhua, the main difficulty of graphene composite powder technology lies in the graphene oxidation and reduction process. The common method of oxidation process on the market is to oxidize with concentrated sulfuric acid and potassium permanganate, and the technology of this project is inherited. In Zhejiang University, potassium permanganate was replaced by potassium ferrate. The graphene produced was green, safe and gentle, and the time was very short, shortening from 12 hours to 1 hour.
At the same time, the concentration of graphene is particularly low, the commonly used concentration on the market is within 10%, and the concentration of graphene oxide prepared by this method can reach more than 50%, which has the basic conditions for industrialization. With oxidized graphene, by adding surfactants, reducing agents and composite powders, while adding in the control reaction step, the graphene can be evenly wrapped on the surface of the sphere and the sheet powder.
Project outcome
SXYY is the first batch of companies in China that can produce graphene with green processes. The graphene coatings prepared by this company are also the first products in China to obtain industry certification. By preparing graphene itself and adding graphene to the coating to improve, using these technologies won the gold medal in the 2016 Beijing University Student Entrepreneurship Competition and the 2017 National University Student Entrepreneurship Competition Special Prize, and won the China Graphene Industry in 2018 The Alliance’s Industry Special Contribution Award will be selected as a new material application project in Shaanxi Province in 2020.
The coatings designed by SXYY have very good applications in petroleum systems. At present, the company has established two R&D centers in Zhongguancun, Beijing and Peking University, and production bases for related industries in Langfang, Hebei and Qianhe Town, Baoji. It is worth mentioning that, The company invested 1 billion in Baoji Fengxiang Industrial Park to build the largest graphene coating production base in Northwest China. In recent years, it has also launched in-depth cooperation with petrochemical companies in Hebei, Guangdong and other cities.
It is understood that the project has issued 4 patents, and currently has more than 100 million yuan in financing. The amount of newly signed orders in 2020 has exceeded 170 million yuan, and the sales are expected to exceed 1.5 billion yuan in the next five years.
