China's Synthetic Adhesives Will Have Great Development During the 11th Five-Year Plan Period

China's synthetic adhesives will have tremendous development during the 11th Five-Year Plan period. "Eleventh Five-Year" China's demand for various types of adhesives and sealants is forecast to increase at a rate of more than 10% per year. By 2010, total output will reach 7.3 million tons, an average annual growth rate of 11.5%, and a total value of 570 yuan. Billion, with an average annual growth rate of 11.8%. According to the prediction of relevant experts, the demand for adhesives and sealants in various applications in 2010 was distributed as follows: 3.33 million tons of plywood for woodworking and carpentry, 2 million tons of building materials and coatings, 890,000 tons for packaging and trademarks, and 430,000 for shoes and leather Tons, transportation 240,000 tons, paper processing and books binding 150,000 tons, assembly (mechanical, electrical, instrumentation, etc.) 127,000 tons, civilian consumption 53,000 tons, and other 80,000 tons.

The development trend of the synthetic adhesive industry is represented by four major characteristics: First, the accelerated development of environmental protection and energy-saving products is expected to increase at a rate of 12 to 20% per year during the “Eleventh Five-Year Plan” period; second, high performance and high-quality adhesives Development, especially for adhesives in the fields of mechanics, electronics, automotive, construction, medical and aerospace and aerospace, will grow faster. Some of the production of special adhesives will increase at a speed higher than 20%; third, the production of adhesives will be scaled up and intensified. The advantages of enterprises are concentrated, and the quality and grade of products will be greatly improved. Some enterprises with large production scale, high technological level, and strong innovation ability will have greater development, and will become bigger and stronger, while some have small production scale and technologies. Laggard enterprises will speed up their elimination; Fourth, foreign-funded enterprises will continue to develop, the number of enterprises will increase, production scale will increase, capital investment will increase, and high-tech products will increase significantly. Some of the world’s leading companies will set up R&D centers in mainland China to strengthen the research and development of new and high technologies and further improve the product quality. It is expected that the sales of foreign-funded enterprises will increase by 40% of the total sales of adhesives in mainland China at the end of the “Eleventh Five-year Plan” period. To 45 to 50%.

According to the target of producing 7.3 million tons of adhesives and sealants (average annual growth of 11.5%) and sales of 57 billion yuan (equivalent to US$6.9 billion, with an average annual growth of 11.8%) in 2010, China’s adhesive and sealant production will rank Ranked first in the world, sales ranked third in the world. In order to achieve the “Eleventh Five-Year” development goal of China's synthetic adhesive industry, we must first adhere to the scientific concept of development, take the road of new industrialization, and build the adhesive industry into sustainable development and environmental protection with low input, high output, low energy consumption, and recyclability. Type, healthy fine chemical industry. Focus on the development of environmentally friendly, energy-saving adhesives, and vigorously research and development and development of high-tech, high value-added, high-performance adhesive new products.

The key development varieties mainly include the following types. The first is waterborne products: First, waterborne polyurethane adhesives. Because of its good adhesive properties, polyurethane adhesives are widely used in the footwear, construction, automotive, food packaging and other industries. Waterborne polyurethane adhesives and solvent-free polyurethane adhesives are environmentally friendly and energy-saving. The products have been widely used in developed countries such as Europe, the United States, and Japan in recent years and have not yet been successfully developed in China. Experts suggest that while increasing the research and development of waterborne polyurethane adhesives, they will actively introduce production technologies and processes and build 5,000 tons/year. Production equipment for the production of waterborne polyurethane adhesives for shoes and woodworking; waterborne neoprene rubber adhesives; waterborne neoprene rubber is an environmentally friendly adhesive with a wide range of uses. It has been developed in developed countries in Europe, America and Japan. Soon, and has been applied in the construction, furniture, footwear industry, but not yet developed in China, waterborne neoprene adhesive is the main product of research and development during the "Eleventh Five-Year" period in China; third is VAE emulsion, VAE emulsion is One of the very good types of rubber in waterborne adhesives. In 2004, the output of VAE emulsion in China was 100,000 tons. Can not meet the needs of economic development, if they can build a set capacity of 100,000 tons / year of the "Eleventh Five-Year" period VAE emulsion production plant, it can basically meet the domestic market demand.

Followed by high-performance products, mainly refers to high-performance high-quality pressure-sensitive adhesives and products. High-performance, high-quality pressure-sensitive adhesives and products mainly include the following types: one-time super adhesive strength acrylic pressure sensitive adhesive (PSA) and adhesive tape, requiring a 180 degree peel strength of ≥12N/cm; second, good heat resistance ( Heat-resisting temperature ≥150°C) or electrical power, thermal insulation protective acrylic pressure-sensitive adhesive and tape with electrical properties up to class H; Third, high temperature resistance, strong moisture resistance (at temperatures ≥65°C, humidity above 90% Acrylic pressure-sensitive adhesives and labels with a time of ≥7 days; Fourth, silicone pressure-sensitive adhesives and tapes; Fifthly, a re-sticky spherical suspension acrylic pressure-sensitive adhesive with a memo paste; etc.; Acrylic pressure-sensitive adhesives and products that are washable, hypoallergenic and moderately viscous. In the “Eleventh Five-Year Plan” period, a set of production equipment and coating production line with an annual output of 5,000 tons, high-performance and high-quality acrylic pressure-sensitive adhesives shall be researched, developed and constructed.

Again the resin material. First, EVA resin, hot melt adhesive is an environmentally friendly adhesive. In 2004, the output of China's hot melt adhesive was about 65,000 tons. The rubber species grows at a rate of 15% per year. By 2010, the demand for hot melt adhesives in China is expected to be about 16%. 10,000 tons, but EVA resin, the main raw material for the production of hot-melt adhesives, is currently not available in China and all of them need to be imported. This is incompatible with the rapid development of hot-melt adhesives. It should be built with an annual output of 10 during the “Eleventh Five-Year Plan” period. Tens of thousands of EVA devices meet China's hot-melt adhesives and other development needs; Second, SIS resin, SIS resin is an important raw material for the production of hot-melt pressure-sensitive adhesives and other adhesives. In 2004, the output of hot-melt pressure-sensitive adhesives in China was approximately 63,000. Ton, it is expected that the rubber species will grow at a rate of 10 to 20% per year. At present, the only domestic production enterprise of SIS resin is Baling Petrochemical, with a production volume of 5,000 tons/year. It is far from meeting the demand both in terms of quantity and quality. It is necessary to import from abroad. It is necessary to build a SIS resin device with a production capacity of 20,000 to 30,000 tons during the “11th Five-Year Plan” period. At the same time, Yanshan Petrochemical, Jilin Petrochemical, etc. will build an isoprene purification device to meet the production of SIS resin. The original Supply.

To achieve the “Eleventh Five-Year” development goal of China's synthetic adhesive industry, it also needs multi-faceted support. Experts said that first of all, the state should increase its research investment in some important adhesive products. At present, apart from paying more attention to some adhesive products used in the defense industry, especially in the aerospace industry, there are almost no inputs for some civilian products, such as footwear, wood processing, and construction-use polyurethane adhesives; home decoration, construction, and carpentry. Water-based neoprene rubber adhesives and other widely used products have already achieved industrial production in foreign countries, but there is still no major progress in China. The above products are not only environmentally friendly but also save a large amount of solvent (about 200,000 to 300,000 tons) per year. During the “Eleventh Five-Year Plan” period, the state should increase investment in the research and development of waterborne polyurethane adhesives and waterborne neoprene adhesives so that they can achieve industrial production as soon as possible, and investment in R&D of some important new adhesive products is also very necessary.

In addition, it is an important part to further develop the role of industry associations and strengthen the guidance of enterprises. Industry associations should vigorously promote the country’s industrial policy and scientific development concept, and provide companies with various information at home and abroad, including technology, economy, products, and markets, so that they can quickly understand and master new trends in the domestic and foreign markets. The development trend; and strengthen the links between domestic and foreign industries, exchanges and cooperation, expand investment promotion, in particular to help some companies to find and introduce advanced production technologies of some new products; actively support and help 3 to 5 products in line with national industrial policies, Companies with strong scientific and technological development capabilities and good management and business management have enabled them to achieve large-scale, intensive production, further expand and strengthen, create China's brand-name products and famous enterprises, strengthen industry guidance, and formulate industry self-discipline measures. Vigorously publicize and implement the spirit of the "Eleventh Five-Year Plan" of the petroleum and chemical industry, combined with the current situation of small-scale production, overproduction of low-grade products, and increasing pollution problems in the industry, and work with local industry and commerce departments to strengthen the market under the guidance of government departments and industry associations. Management, crack down on fake and shoddy products, standardize market rank .

Accelerating the localization of raw materials and related auxiliaries required by the adhesive industry is becoming more and more urgent. Experts said that adhesive products are increasingly used in important fields such as electronics, machinery, and defense. Currently, most of the domestic engineering adhesives and sealants with excellent technical performance are products that use imported or joint ventures. The raw materials used in the products developed still rely on imports. This long-term reliance on imported raw materials to restrict China's self-development of high-performance adhesive products must be resolved as soon as possible. In addition, we must pay attention to the development of industry regulations and standards for sustainable development, combined with the (eco-friendly) restrictions on Asian products in the world economy and trade in recent years, the adhesive industry in China should conclude that the coatings and daily-use cosmetics industries have restricted the export of products in recent years. Based on the experiences of Asian countries such as Japan, the United States, and the European Community in recent years, related regulations on environmental protection of adhesive products, etc., experts are organized to conduct research and formulate corresponding regulations and measures as soon as possible. First, it is used in areas where conditions permit and export products are used, and then expanded to the whole country. To make China's adhesive industry detours and healthy development, as soon as possible to become a low-input, high-yield, low-consumption, low pollution, renewable, sustainable development of the sunrise industry.
