It is expected that this year and next year, the trend of China's paint market will show the following characteristics.
First, the balance between supply and demand in the paint market is basically balanced, and the demand is slightly expanded. According to the domestic production and sales volume of decorative paints, which are calculated at an annual rate of 9% to 15%, the national paint supply will be around 2.6 million tons in 2005. The market demand will exceed 2.55 million tons, and the balance between supply and demand will be basically balanced. Among them, the demand for industrial coatings is about 900,000 tons, accounting for 35% to 40%; the architectural coatings are 1.15 million tons, accounting for 45% to 50%; the special coatings and other functional coatings are 500,000 tons, accounting for 10% to 15%.
Second, the development of the automobile industry and the real estate industry will be restrained to a certain extent, but urban and rural residential construction will continue to be a hot spot for consumption. Continued decoration and project completion will further stimulate the demand of the paint market in China. In 2005, the area of ​​newly-built urban residential buildings in China will reach 300 million square meters, while the existing 2.9 billion square meters of urban housing will be transformed to varying degrees. The South-to-North Water Transfer Project will accelerate the construction of a large number of flood control, power generation, water storage and water diversion projects. It is the construction of rural well-to-do villages that will further heat up. In the next three years, rural areas in China will have 568 million square meters of residential demand, so the rural paint market has great potential.
Third, environmental-friendly high-grade coatings and multi-functional coatings will be favored by the state's key projects. The water-based paint market will become even more prosperous and will become the most promising coating product in the coating market. China's current coating market has a surplus of middle and low-end products, and some high-end products are in short supply. This has brought a broad market space for low-pollution and process-clean water-based coatings. In particular, the demand for industrial water-based paints is most urgent, and more than 1 million tons of industrial paints will become the breakthrough point for water-based paints to break the market. According to incomplete statistics, the annual demand for industrial coatings in China is around 1.7 million tons, of which about 1 million tons can be replaced by water-based industrial anti-corrosion coatings. It is expected that in 2005, the application of waterborne industrial coatings in China will increase to 35%.
In 2005, the annual output of architectural coatings in China will reach 1.8 million tons, and the application rate of exterior wall decoration will be more than 35%. Traditional paints used in the past will be replaced by water-based paints with good environmental protection properties. However, at present, the proportion of environmental protection coatings in China is less than 30%, which is far below the level of developed countries. With the strengthening of environmental protection regulations, the environmental protection rate of coatings will be increased to 40% in 2005.
Therefore, in the future, China will focus on the development of the following types of coatings.
One is water-based paint. On the basis of further reducing VOCs, research on the mechanism of cross-linking of water-borne resins and the development of new cross-linking agents are being carried out to improve the performance of room-temperature-curing water-based paints; research on construction techniques is carried out to reduce the influence of environmental temperature and humidity on the appearance of coating films; The coating film has a low fullness and a low gloss, and high performance coatings are developed to expand its application fields. By further reducing the cost of waterborne coatings, the issue of recovery and reuse of coatings can be solved.
The second is powder coating. Focus on the development of internally blocked isocyanate powder coatings to improve the durability of outdoor powder coatings. At the same time, develop powder coatings for powder coatings, heat-sensitive substrates, especially UV curing powders and organic pigment dispersions. Solve color inconsistencies.
The third is high solids coatings. To further improve the solids content of the coating, strive to reach 80% or even 100% solids; develop anti-sagging additives with better sag resistance, such as microgels, and the secondary antibody sagging film thickness of 60μm or even 100μm or more Constantly improve the mechanical properties of the coating, especially the balance between flexibility and impact resistance.
Fourth, UV curing coatings. Expand application areas, reduce raw material prices; Improve curing of coloring systems with new photoinitiators and equipment designs; Improve construction techniques, especially spray coating techniques, to solve rheological problems; Combine UV curing coatings for three-dimensional parts with heat curing The dual curing technology designed the facilities needed for this technology; solved the toxicity of acrylic oligomer monomers and developed alternatives.
In addition, the market prospect of functional architectural coatings is also very promising, including fire-retardant coatings, waterproof coatings, anti-mold and anti-insect coatings, rust-proof and anti-corrosion coatings, anti-static coatings, sound-absorbing coatings, thermal insulation coatings, and elastic functional coatings. Variety. Fire-retardant coatings are mainly used for researching effective fire-retardants and flame-retardants to increase the effect of preventing the expansion of combustion. The development trend of waterproof coatings is water-based waterproof coatings. The anti-mold and anti-insect coatings focus on the development of high-efficiency and non-toxic bactericidal products to be applied as soon as possible. The construction of the food industry; the development direction of anti-corrosion and anti-corrosion coatings is the use of high-efficiency non-toxic anti-rust pigments, development of long-lasting anti-corrosion coatings and varieties with excellent weatherability.
In industrial coatings, China will gradually expand the proportion of waterborne coatings, high solids coatings, powder coatings, solvent-free coatings and radiation-curing coatings.
To develop four kinds of coatings for environmental protection, high-grade and multi-functional development will become the focus of development
In recent years, the rapid development of China's paint industry, especially the rapid rise of residential construction, energy transportation and automobile industry, has driven a substantial increase in market demand for architectural coatings, road marking coatings, automotive coatings, anti-corrosion coatings and coil coatings. At present, the total production of paint in China is second only to the United States, ranking second in the world.
