According to incomplete statistics, up to now there are more than 6000 kinds of adhesive products come out, because of its variety, different components, there is no uniform classification method.
Urea formaldehyde resin, phenol formaldehyde, melamine formaldehyde adhesive: mainly used in wood processing industry, the use of formaldehyde emission is higher than international standards.
Polyacrylic acid resin: mainly used in the production of pressure sensitive adhesive, also used in textile and construction field. In recent years, domestic enterprises to introduce a number of pressure sensitive adhesive production line from abroad, to promote the development of domestic polyacrylic acid resin production technology.
Polyurethane adhesive: adhesion of a variety of materials, bonding at low temperature or ultra-low temperature can still maintain the physical and chemical properties of materials, mainly used in shoes, packaging, automotive, magnetic recording materials and other fields. In recent years, the annual output of polyurethane adhesive in China is growing at an average rate of 30%. At present, there are about 170 factories in the production of more than 100 kinds of different specifications of such adhesives.
Hot melt adhesive: according to different materials, can be divided into EVA hot melt adhesive, polyamide hot melt adhesive, hot melt adhesive, hot melt adhesive polyester polyolefin etc.. At present, the production and use of EVA hot melt adhesive. The main raw material of polyolefin series adhesive is ethylene series, SBS, SIS copolymer.
Epoxy resin adhesive: it can be used for bonding between metal and non-metal materials. It is widely used in construction, automotive, electronics, electrical appliances and household items. Domestic production of epoxy resin adhesive factory has more than and 100, distributed more dispersed, the annual output of about 10 thousand tons.
Silicone adhesive is a kind of sealing adhesive, has the characteristics of cold and heat resistance, aging resistance, waterproof, moisture-proof, expansion of high fatigue strength, small permanent deformation, non-toxic etc.. In recent years, the rapid development of such adhesives in China, but now some of the raw materials of China imported silicone adhesive.
Synthetic adhesive: mainly used in wood processing, construction, decoration, automotive, footwear, packaging, textiles, electronics, printing and other fields of binding. At present, China's annual imports of nearly 200 thousand tons of synthetic adhesives, including varieties of hot-melt adhesive, silicone sealant, polyacrylate adhesive, polyurethane adhesive, PVC plastic adhesive can be used car etc.. At the same time, the annual export of synthetic adhesives about 20 thousand tons, mainly polyvinyl acetate, polyethylene acid formaldehyde and pressure-sensitive adhesive.
Adhesives for wood processing: for MDF, gypsum board, plywood and particleboard.
Adhesive for construction: mainly used in the decoration of construction projects, sealing or structural bonding. With the development of the construction industry, the development of high-rise buildings, interior decoration needs, the rapid increase in the amount of adhesive used in construction. China's construction adhesives consumption of about 600 thousand tons. But experts believe that China's product structure of such adhesives need to adjust. In our country, the adhesive used in architectural decoration, such as polyvinyl acetate, polyacrylic acid and VAE emulsion, can meet the need basically, but the sealing adhesive and structural adhesive used in the building need to be imported from abroad.
Sealing adhesive: mainly used for doors, windows and prefabricated prefabricated parts of the connection. In the past as a sealant with tung oil and lime mixing, now provides more than two storey buildings must use synthetic adhesives. High grade sealing adhesive for silicone and polyurethane adhesive, medium for chloroprene rubber adhesive, polyacrylic acid, etc.. In our country, on the market for building adhesives, silicone adhesives, polyurethane sealing adhesive should be the direction of future development, the building occupies about 30% of the sales of sealing adhesive.
Adhesive for building structures: mainly used for connection between structural units. Such as the external repair of reinforced concrete structures, metal reinforcement and construction site construction, generally consider the use of epoxy resin series adhesive.
Adhesive for automobile: it is divided into 4 kinds, that is, the car body, the interior decoration, the windshield and the chassis adhesive. At present our country automobile adhesive consumption is about 40 thousand tons, which is the largest volume of PVC plastic adhesive, chloroprene rubber adhesive and asphalt adhesive.
Adhesives for footwear: annual consumption of about 125 thousand tons, of which chloroprene rubber adhesive needs to be about 110 thousand tons, about 15 thousand tons of polyurethane adhesive. As a result of chloroprene rubber adhesive need benzene as solvent, and benzene harmful to human body, should limit the development, so in order to meet the needs of the development of the footwear industry, using polyurethane series adhesive will be the direction.
Packaging adhesive: mainly used in the production of pressure sensitive adhesive tape and pressure-sensitive labels, paper, plastic, metal and other packaging materials on the surface of the adhesive. Adhesive for paper packaging material is polyvinyl acetate emulsion. Plastic and metal packaging material with adhesive for polyacrylic emulsion and VAE emulsion, polyurethane adhesive and cyanoacrylate adhesive.
Electronic adhesives: less consumption, the current year is less than 10 thousand tons, mostly used in integrated circuits and electronic products, mainly with epoxy resin, unsaturated polyester resin, silicone adhesive. We are able to supply the sealing adhesive for 5 micron thick electronic components, but the adhesive for the 3 micron thick electronic component is imported from abroad.
Rigorous, scientific research methods to ensure the accuracy and quality of the research report. "Research methods 2010-2015 market depth Chinese adhesive industry research and investment forecast report" mainly used are: 1) census: We conducted interviews or telephone access to hundreds of adhesive industry practitioners, to obtain the best first-hand data. 2 tracking research: in order to ensure the real-time grasp of the adhesive industry dynamics, we have established a tracking mechanism in the adhesive industry, access to the development of adhesive industry every month through access. 3 (government) data: we checked the adhesive industry key enterprises of the industrial and commercial archives, bureau archives, customs import and export data, etc., to obtain more authoritative information. 4) SOWT analysis: SWOT analysis, Potter five forces analysis method, we analyzed the adhesive industry and enterprise competition advantages and disadvantages and potential threats and opportunities. 5 scientific prediction: we use regression analysis, time series analysis, factor analysis, combination analysis and other methods to make a full prediction of the development trend of adhesive.
