01 market scale of heavy-duty anticorrosive coating industry

1. The sales revenue of heavy-duty anticorrosive coating industry reached more than 98billion yuan in 2018

corrosion and rust in modern life caused a lot of waste of resources and energy, and huge economic losses will be formed every year. According to the reports released by the United States, Japan, Canada and other countries, the two clamps separate and stretch the samples at a certain speed. The direct economic loss caused by corrosion alone accounts for about 1%-4% of the gross national economic output every year, and the corrosion and rust of steel accounts for about 20% of the annual output. In China, the economic loss caused by metal corrosion accounts for about 4% of the gross national product every year, and the corrosion loss even exceeds the fire The sum of losses caused by wind and earthquake. Such amazing losses undoubtedly stimulate the growth of the market demand for anticorrosive coatings. With the technological progress of heavy-duty anticorrosive coatings and the application of modern spraying equipment, especially the vigorous promotion of high-pressure airless spraying equipment, solvent-free double port spraying equipment, powder spraying equipment, etc., heavy-duty anticorrosive coatings are extended to the field of special anticorrosive coatings. In 2018, the industry achieved a sales revenue of 98.447 billion yuan

2. In 2018, the total output of anti-corrosion coatings reached more than 4.27 million tons

there are more than 1000 varieties of heavy-duty anti-corrosion coatings in China, with about 900 manufacturers, including more than 100 manufacturers specializing in anti-corrosion coatings and dozens of manufacturers with an annual output of more than 1000 tons. In recent years, China's heavy-duty coatings have developed rapidly, and their varieties have also developed in the direction of multi-function. In 2017, the total output of heavy-duty coatings in China reached 3.887 million tons, ranking first in the world. According to the statistics of relevant institutions, the total output of heavy-duty anticorrosive coatings in 2018 reached 4.271 million tons

3. In 2018, foreign enterprises accounted for 60% of the domestic anti-corrosion coating market share.

the field of heavy-duty anti-corrosion coating is the earliest and most internationalized field of China's coating industry. At present, the internationally renowned heavy-duty coating brands, hempel/Denmark, international paint (international/Netherlands), Jotun (jotun/Norway), China paint (cmp/Japan), master paint (ppg/USA), Aksu 7 Setting the experimental speed: there are speed regulations in the standard: the speed of 10% of the initial thickness. With their technology, brand and management advantages, Nobel (akzonobel/Netherlands), King Kong (kcc/South Korea) and others have conquered cities and territories in China, and have completed the domestic production and strategic layout in China. Nippon, Xuanwei, PPG and others have established their own factories and laboratories in China, Form a monopoly situation for foreign enterprises in the high-end market of heavy-duty anticorrosive coatings in China. Domestic heavy-duty anti-corrosion coating enterprises are mainly small-scale enterprises, which are difficult to compete with international coating giants in terms of capital, technology and brand. This phenomenon is particularly evident in the important components of anti-corrosion coatings, such as automotive anti-corrosion coatings and marine container coatings. In the field of container and marine coatings, due to the high requirements for coating technology, foreign-funded enterprises and joint ventures account for 80% of the domestic market share. In general, about 60% of China's anti-corrosion coating market is occupied by foreign enterprises, and foreign anti-corrosion coating enterprises mainly occupy the medium and high-end coating Market; The domestic anti-corrosion coating enterprises that survive in the low-end market have serious problems such as homogenization, so that at present, the profit space of many anti-corrosion coating enterprises in China has been compressed below the normal profit warning line of 10%, and the rise of China's anti-corrosion coating enterprises still has a long way to go

02 existing problems in China's industrial anticorrosive coating industry

since the reform and opening up, China has made great progress in the field of anticorrosive coating technology. Some high-performance coating products have been developed and successfully applied to large-scale projects in many countries. However, compared with some well-known foreign brands, our overall level still lags far behind that of foreign countries, which is reflected in the following aspects: first, there are many manufacturers, relatively small scale, wide distribution range and low profit level, so we cannot compete with foreign well-known brands. There are more than 9000 paint manufacturers in China, but few large paint enterprises with annual sales of more than 200000 tons, and 80% of them are small and medium-sized enterprises. It is a large-scale enterprise, and the scale of coating enterprises in the world is not in the top 50. Second, the independent innovation ability of coating manufacturers is relatively insufficient and lack of core competitiveness. Third, the degree of specialization of coating manufacturers is not enough, and the supporting facilities are not complete. Fourth, paint manufacturers often pay more attention to the research of product performance, but the research of coating supporting system and construction technology is insufficient. Fifth, the level of standardization is low. Sixth, the brand construction is not enough. In general, in the field of heavy-duty anti-corrosion coatings, domestic enterprises lack core competitiveness, and there is still a big gap in production scale, product grade, construction quality, service level, etc., so it is difficult to enter the high-end market with current strength

03 development trend of heavy-duty anti-corrosion coatings

1. Waterborne

with the increasingly urgent and strict requirements of the public for environmental protection, the development of waterborne heavy-duty anti-corrosion coatings with low energy consumption, low pollution and high performance has become one of the current research hotspots. The key to the research and development of waterborne heavy-duty anticorrosive coatings is the development of water-soluble film-forming resin. At present, waterborne epoxy, waterborne fluorocarbon and waterborne polyurethane anticorrosive coatings have been successfully developed. However, the water-based heavy-duty anti-corrosion coating still has some shortcomings, such as prone to flash corrosion, relatively poor water resistance and mechanical properties of the film, which need to be further improved

2. Non toxic antirust pigments

as an important part of heavy-duty anti-corrosion coatings, antirust pigments play a role in slowing down metal corrosion. Although the common antirust pigments containing heavy metals have excellent performance, they will cause great pollution to the environment, so they are gradually limited in practical use. In recent years, using environment-friendly antirust pigments to replace traditional antirust pigments has become the development direction of current environment-friendly heavy-duty anti-corrosion coatings. However, to completely replace traditional toxic antirust pigments, we need to strengthen research and development on the theory and application of non-toxic antirust pigments

3. Multifunctional

single function heavy-duty anti-corrosion coatings are far from meeting the huge needs of the modern coating industry, and the diversification of heavy-duty anti-corrosion coatings' functions is imperative. Such as composite ceramic high-temperature anti-corrosion coating, conductive polyaniline heavy-duty anti-corrosion coating, self-healing heavy-duty anti-corrosion coating, nano composite powder zinc impregnation heavy-duty anti-corrosion coating. In order to promote the development and product upgrading of heavy-duty anticorrosive coatings and seize the commanding height of the development of heavy-duty anticorrosive coatings in the world, great attention must be paid to the multifunctional heavy-duty anticorrosive coatings

4. Paint and coating integration

three points of paint and seven points of construction. Coating itself can be said to be a semi-finished product, which will eventually become a finished product when combined with coating. It can be seen that the importance of coating quality directly determines the final project quality. So far, the integrated system management of paint and coating is still the top priority of China's paint industry. When developing coating products, we must pay attention to the research of coating process. Only after the integration of coating and coating is realized, the continuous price rise of copper foil can realize the "reliability" of the final product; At the same time, the new coating process and coating technology will also promote the upgrading of coating products. In recent years, the base material table before painting, a toy manufacturer headquartered in Billund, announced on June 16 that the investment decided to gradually increase the surface treatment cost and labor cost, which promoted the development of low treatment surface primer products; Wet sand blasting and high-pressure water derusting process have expedited the development of wet rust surface primer. Of course, the new coating process also puts forward higher requirements for the construction performance of coating products, which also promotes the performance improvement of heavy-duty anti-corrosion coatings. Based on the above analysis, it is necessary to strengthen the coating specification of the industry, improve the technical service ability, and establish a high-quality technical service team

04 development direction of heavy-duty anti-corrosion coatings

the development direction of anti-corrosion coatings is energy conservation, environmental protection, high performance and functionality. This also requires the coating industry to develop towards water-based, solventless or high solid, powdered, high-performance and multifunctional, low surface treatment, heavy metal free and other low pollution and pollution-free directions. Various water-based coatings, high solid/solvent-free coatings, low surface treatment primers, nano modified coatings, conductive polyaniline coatings, one component moisture curing polyurethane coatings, ultra-high pressure water jet cleaning technology, as well as peelable protective coatings and new pollution-free antifouling coatings for the marine environment have been continuously concerned and developed. Developing environment-friendly industrial heavy-duty anticorrosive coatings is a high-tech project that many developed countries are actively exploring, and it is a new field in China. In the field of heavy-duty corrosion protection, due to the early integration with foreign technology and the drive of various regulations and policies, some environment-friendly and efficient products have been widely used
