Relevant experts predict that the expected goals of China's adhesives and sealants in 2010 indicate that China's adhesive and sealant production will rank No. 1 in the world, and sales will rank No. 3 in the world. Experts predict that China's adhesive production in 2010 will reach 7.3 million tons, an average annual growth rate of 11.5%; sales reached 57 billion yuan, an average annual growth rate of 11.8%.
Environmental-friendly, energy-efficient adhesives will focus on development in the next five years. Experts say that high-performance epoxy adhesives, epoxy adhesives for the electronics industry, and epoxy structural adhesives for the construction industry are difficult to produce and have poor domestic product quality. Currently, they mainly rely on imports. Greatly higher than the average growth rate, localization will gradually realize in 5 years. The other five types of adhesives will also become hot spots: low formaldehyde emission urea-formaldehyde adhesives, hot-melt adhesives, polyurethane adhesives, silicone adhesives, and automotive plastic melt adhesives. At the same time, China will also vigorously study the development and development of high-tech, high value-added, high-performance adhesive products, including: waterborne polyurethane adhesives, waterborne neoprene adhesives, high-performance and high-quality pressure-sensitive adhesives and products, VAE (vinyl acetate-ethylene) emulsion, EVA (ethylene-vinyl acetate) resin, SIS (styrene-isoprene-styrene) resin, and the like.
Waterborne polyurethane adhesives and waterborne neoprene rubber adhesives are environmentally friendly products. In recent years, they have developed rapidly in industrialized countries such as Europe, America and Japan, and have been widely used in construction, furniture, shoemaking and other industries. Is still blank. Therefore, in the next five years, China will not only increase the research and development of these two types of adhesives, but also plan to introduce advanced foreign production technologies and processes and build a 5000 tons/year waterborne polyurethane adhesive production device to solve some of the needs of the domestic market. In terms of high-performance and high-quality pressure-sensitive adhesives and products, China plans to build a 5,000-ton/year high-performance, high-quality acrylic pressure-sensitive adhesive production device and coating production line.
VAE emulsion is one of the best types of glue in waterborne adhesives. In 2004, the output of VAE emulsions in China was only 100,000 tons, which was far from meeting the market demand. In the next five years, it plans to build another 100,000 tons/year of production equipment. Hot melt adhesive is an environmentally friendly adhesive. In 2004, China's output was about 60,000 tons, and it is estimated that the output in 2010 will reach 160,000 tons. However, the main raw material for the production of the rubber EVA resin is currently all dependent on imports, so our country plans to build 10 Million / year EVA resin production device to solve the development of hot melt adhesives. SIS resin is an important raw material for the production of hot-melt pressure-sensitive adhesives and other adhesives. At present, China only has production facilities with an annual output of about 5,000 tons. It is far from meeting the needs of the domestic market both in quality and quantity. It is planned to build 30000 in the future. t/year SIS resin production device.
