China's anti-corrosion coating technology development trend

Anti-corrosion coating is a coating widely used by modern industry, transportation, energy, marine engineering and other departments. According to the degree of corrosion resistance of the paint film and the use requirements, it is usually divided into two types: conventional type and heavy anti-corrosion type. Anti-corrosion coatings occupy an increasingly important position in the paint industry. The development of anti-corrosion coatings is of great significance to the economic development of China. It is expected that by 2017, the total output of anti-corrosion coatings will reach about 6 million tons. Due to the wide application of heavy anti-corrosion coatings, the status of the industry is extremely important, and it is also important for energy conservation and emission reduction. The state encourages and supports the research, development, and production of heavy anti-corrosion coating technologies. It is expected that the production capacity of some conventional anti-corrosion coatings will shift to heavy anti-corrosion coatings.

China's anti-corrosion coatings are mainly used in the chemical and petroleum industries, railways, highways, bridges, metallurgical industries, power and energy industries, machinery and textile industries, industrial products, automotive, marine and container industries. Among them, the industries with the greatest demand are the chemical and petroleum industries, which include corrosion protection of steel structures and reinforced concrete structures of oilfield facilities, oil pipelines, offshore platforms, and petrochemical plants; at the same time, the construction and maintenance of railways and highway bridges are also anticorrosive. The key areas of application of coatings; In addition, the field of industrial products and marine anti-corrosion fields such as automobiles and ships are the biggest demand points in the anticorrosive coating market. While anti-corrosion coatings in our country are continuously developing, anti-corrosion coatings are advancing in the direction of high performance, high efficiency, low energy consumption, and low pollution. Anti-corrosion of ships, oil platforms, container anti-corrosion, chemical anti-corrosion coatings, railways, highways and bridges, and steel structure anti-corrosion are still the focus of the market. At the same time, the scale of competition in anti-corrosion coatings will also expand, the competitive landscape will become more apparent, and international cooperation will become increasingly important.

The data shows that the average annual growth rate of the production of corrosion protection coatings for the petrochemical industry, power industry, and construction steel structures will remain at around 20% in the next five years; the average annual growth rate of ships and railroad anti-corrosion coating production will remain at around 17%; The average annual growth rate of container anti-corrosion coating production will remain at around 8%.

Future development of anti-corrosion coating products mainly shows the following aspects:

1. Develop waterborne anticorrosive primers and topcoats for steel structures;

2. Develop high solids and solvent-free anti-corrosion paint series;

3, the development of water-based zinc-rich primer;

4, the development of heat exchanger with room temperature curing heat-resistant anti-corrosion coating;

5. Develop coatings that can be cured at room temperature and facilitate construction;

6, the development of chlorinated rubber series of anti-corrosion coating substitutes;

7, the development of scale-like anti-corrosion coatings;

8, the development of organic modified inorganic anti-corrosion materials.

At the same time, the anti-corrosion coating market and the future direction of the company:

1. Water-based anti-corrosion coating products are favored.

2, coating technology and coating technology more closely.

3, pay attention to cleaner production.

4, more detailed market and product.

5, emphasis on production technology research.

With China's infrastructure construction, industrial restructuring and the development of emerging industries, anti-corrosion coatings will undoubtedly become an important field and branch in the coating industry and market system, related to participating companies, technological development, product systems, market size, and actual needs. The applications, applications, functions, etc. have reached a new level at present, and many industry experts believe that the most advanced manufacturing scale in industrial coatings, high production efficiency, and good production capacity, should be anti-corrosion coatings. Anti-corrosion coatings have become an important force in the coatings field, playing a more and more important role and have a promising development prospect.
