China's waterborne polyurethane adhesive has a bright future

According to relevant experts' forecasts, the demand for synthetic adhesives in China has a broad market, and waterborne polyurethane adhesives have conquered the market with its superior performance and environmental protection and energy conservation.

The waterborne products of synthetic adhesives developed in China mainly include the following: First, waterborne polyurethane adhesives. Due to its good adhesive properties, polyurethane adhesives are widely used in the industries of footwear, construction, automotive, food packaging, etc., waterborne polyurethane adhesives and Solvent-based Polyurethane adhesive is an environmentally friendly and energy-saving product. It has been widely used in Europe, the United States, Japan, and other developed countries in recent years. It has not yet been successfully developed in China. Experts recommend that the research and development of water-based polyurethane adhesives should be actively introduced. Technology and process, construction of 5000 tons/year of production equipment for the production of footwear and woodworking water-based Polyurethane Adhesive; Second, water-based neoprene rubber adhesive, waterborne neoprene is a widely used environmental protection adhesive, in Europe and the United States The developed countries such as Japan and Japan have developed rapidly in recent years and have been applied in the construction, furniture, and shoemaking industries. However, they have not yet been successfully developed in China. Waterborne neoprene adhesives are the main products for research and development during the "Eleventh Five-Year Plan" period in China. Third, VAE emulsion, VAE emulsion is a very good type of waterborne adhesive In 2004, the output of VAE emulsions in China was 100,000 tons, which was far from meeting the needs of the national economic development. If one set of VAE emulsion production equipment with a capacity of 100,000 tons per year can be built during the [Eleventh Five-Year Plan" period, it can be basically Meet the needs of the domestic market.

At the same time, it is more and more urgent to speed up the localization of raw materials and related additives needed for the adhesive industry. 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.
