Development trend and prospect of decorative architectural coatings in China
Under the planned economic conditions, the paint industry belongs to the chemical sector, and there are 115 paint manufacturers. Except for the basic autonomous regions, paint factories are built all over the country, of which Jiangsu has the most, followed by Guangdong, Hubei, Heilongjiang, and Hunan In the province and Shanxi province, there is only one paint company in Xinjiang, Ningxia, Qinghai, Hainan and other provinces.
Among these paint manufacturers, the varieties produced are mainly industrial paints and special paints, which account for about 75% of the total paint. Architectural coatings, especially water-based coatings, include a relatively small proportion of latex paint production of various resins. After entering the market economy, the pattern of the state-owned paint factory (industry enterprises) unified China's paint market has been broken, especially after the large-scale foreign-funded and joint-venture paint companies with technology, equipment, capital and marketing as a whole enter the Chinese market The architectural coatings market has brought shock waves, and the architectural coatings market has formed a three-legged trend of state-owned paint factories, building material industry enterprises and township enterprises, and joint venture (or wholly-owned) enterprises. There are thousands of architectural coating production plants in China, mainly distributed in Beijing, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong and other provinces and cities, accounting for about 60%. Less than 3% of large enterprises can produce more than 5,000 tons per year, while large enterprises with an annual output of more than 5,000 tons are mostly distributed in coastal areas. Since 1990, there are about 16 architectural coating factories built by foreign companies wholly-owned or joint ventures in China, with a production scale of 20,000-50,000 tons / year. The information shows that in
In China, according to the distribution of paint production and application level, it is more appropriate to be divided into three zones, that is, the best paint development is East China and Central and South China as the first zone; its output distribution is still unbalanced, showing a situation that is heavy in the south and heavy in the north. . It can be seen from this that the quality, speed and speed of the development of the coating industry are inseparable from the situation of economic development.
According to data, the annual growth rate of China's decorative coatings market is about 10%, the annual market value is about 1.3 billion euros, but the annual per capita consumption is less than 1 liter. In Europe, the annual market value is about 11 billion euros, and the annual per capita consumption is 10 liters; in the United States, the annual market value reaches 5.8 billion euros, and the annual per capita consumption is 11 liters, which shows that the Chinese decorative coatings market exists. Huge room for development.
On the other hand, this cake is also getting bigger and bigger with multiple factors: China ’s GDP grows by an average of 9.5% annually, and people ’s living standards have greatly improved; the construction industry continues to develop, and industry data shows that China ’s construction industry has grown by 7% annually, including East China And the growth rate of major cities has reached 15% to 20%; the housing industry has grown rapidly, housing owners have increased by 30% every year, and 59% of Chinese urban residents have their own real estate; coupled with the change in decoration concepts, from the past brick decoration Switch to using decorative coatings, and as young people and urban family houses renovate, the demand for decorative coatings also increases.
The scale of the Chinese decorative coatings market will grow at a rate of 10% per year. In the next ten years, the size of the European decorative coatings market will decrease by 1% per year, while the US market will remain stable. Therefore, China's decorative coatings market will overtake Europe within 10 years, and then catch up with the United States within a period of time, becoming the world's largest decorative coatings market. The future development trend of the Chinese decorative coatings market is unlikely to remain fragmented for a long time. Merger and integration are inevitable. The final result may be similar to the Indian decorative coatings market. Large manufacturers compete in an orderly market, while small local manufacturers Then compete in another more chaotic field.
The development trend of decorative coating industry
The rapid development of the national economy requires high-quality coatings with special properties to match it. The application fields of special coatings are constantly being explored, and various structural facilities, instruments, high-precision products and other surface engineering have put forward higher requirements for surface coating. Aerospace coatings, aerospace coatings, stealth coatings, anti-corrosion coatings, anti-fouling coatings, high-temperature resistant coatings, fire-resistant coatings, temperature indicating coatings, and nuclear power coatings have shown their magical powers. Related companies have accumulated some experience in production and application.
The anti-corrosion coating market has become an object of competition for well-known large companies. Anti-corrosion coatings for metal structures, marine facilities and marine coatings, container coatings, bridges, tunnels and underground engineering will usher in development opportunities. There are also new opportunities for aerospace coatings. China needs a variety of high-performance aerospace coatings to transform itself from a major aviation nation to a strong aviation nation. However, at present, China's special coatings have not yet met the requirements of the aviation industry, and foreign countries often carry out technical blockades. China urgently needs to develop high-performance aviation coatings on its own.
The main development direction of special coatings in the future is antifouling coatings, multi-spectrum compatible stealth coatings, high temperature resistant coatings and other functional coatings. Low technical level is still the biggest problem facing the industry. At the same time, bionic antifouling coatings that imitate the surface of dolphins and shark skins, and low surface energy fluorosilicone antifouling coatings are currently hot spots and difficulties in research and development.
Special coatings are widely used in many fields of the national economy and the defense industry, especially where there are special requirements for coatings. Although their usage is relatively small, the technology content is high and they often occupy the high-end market. At present, the market attention of special coatings is increasing, the development prospect is very optimistic, and the development trend is unstoppable. In line with the current requirements of China's sustainable development, the development of environmentally friendly, energy-saving, multifunctional and high-quality special coatings will attract much attention.
Application status and prospects of highly decorative architectural coatings market
High decorative architectural coatings mainly include sand-wall coatings, multi-layer coatings, brushed coatings, imitation curtain wall coatings, imitation granite coatings, colorful pattern interior wall coatings, cloud coatings, imitation silk coatings, fiber texture coatings and screen printing coatings. Its application varies depending on its decorative effect, physical and chemical properties of the coating film, applicable occasions, and impact on environmental protection and health. In general, it has been applied for a long time and has been developed with increasing demand, or because of outdated decorative effects, bad health due to poor environmental protection, and elimination due to low decorative grades. Curtain wall paint and granite paint are newly developed highly decorative paints. The development of highly decorative architectural coatings is reflected in the development of new products and the development of existing varieties. It summarizes the application and development status of this type of coatings and its prospects for the future.
1.9. Fiber texture coating
This kind of paint does not contain powdery fillers and is only composed of fibers. The base material can form a transparent coating film, so the coating film can clearly show the fibers and have the effect of a blanket. , "Sibi Cai", etc., using the smear method. Due to the combination of different fibers, the coating film has different texture and beauty, and the pattern is rich and has a unique three-dimensional sense, as well as sound absorption and breathability.
1.10 〠Screen printing coating
1.10.1. Composition and performance characteristics of paints or coatings
Including primer, screen printing coating.
The silk screen printing paint is similar to the silk imitation paint, but is not applied by spraying, but by the screen printing, similar to the printing film, because the pearlescent pigment in the paint produces a flash effect and produces a high decorative effect. Although it has a certain decorative effect, the pattern changes are few and dull, which is not as good as the decorative effect of silk paint.
1.10.2, Examples of supporting coatings
