China's footwear industry has always been pollution "heavy disaster area", the traditional mode of production of high energy consumption, low output, not only let the shoe enterprises waste a lot of resources, but also damage the environment in tangible or intangible. In the face of increasingly severe environmental pollution, shoe enterprises must pay attention to the selection and use of production materials adhesives in the course of the operation.
"Twelfth Five Year Plan" period, the countries attach great importance to energy-saving emission reduction, relevant policies and regulations more and more perfect, people's awareness of their own health has gradually improved. Known as the footwear industry environmental pollution "stealth killer", harmful pollutants emitted the shoe manufacturing process on the human body is not to be underestimated. So green water shoe glue into people's vision, then the evolution process of the water shoe glue and its development prospects and how will this, academician of Chinese Academy of Sciences, Fujian Institute of research on the structure of matter, Hong Maochun answer.
China is currently the world's largest footwear producing countries, exports and consumption country, the gooey shoe occupies most of the market. The adhesive 90% for the footwear industry in our country is in the solvent adhesive, and the main pollution source is the unreasonable selection of adhesive for shoes.
According to Hong Maochun, director of introduction, the majority of these organic solvents volatile organic compounds, heavy use of organic solvents except by direct contact persons suffering from occupation disease, emissions in the atmosphere of the organic solvent in the role of ultraviolet light, a photochemical reaction, will produce the ozone and aldehydes and other two pollutants, when encountered bad weather conditions, these pollutants will be the formation of photochemical smog, and photochemical smog will stimulate the eyes and respiratory tract of humans, causing headaches, eye redness, laryngitis, pneumonia and other respiratory diseases.
Relating to expert analysis of the adhesive market and concluded, good quality and no pollution and environmental friendly adhesives with the international standards gradually become mainstream products in the industry. The CAS Fujian Institute of material structure and KELONG Yu Fujian science and technology development of a waterborne polyurethane shoes Development Co. Ltd. joint glue, it has no organic solvent, adhesive strength, no poison, no odor, no explosion danger, no pollution, to human body and environment friendly, and not easy to damage by finishing shoe surface features, applicable to be organic solvent erosion material bonding, is currently developed countries widely used adhesives for shoes.
The shoe factory, green manufacturing is to represent the general trend. KELONG key development company environmental protection, high performance waterborne polyurethane adhesive for shoes with polyurethane polymer design technology and strong shear emulsifying technology, sulfonate hydrophilic chain extender with independent R & D, R & D sulfonate and carboxylate type two aqueous polyurethane shoe with the formulation, preparation technology and detection method of. Successful products with adhesive materials for various shoes, to replace the traditional oil shoe benzene glue, and imported water shoes with PU glue ratio, low cost.
"If the estimated in each of 2000000000 pairs of shoes with aqueous polyurethane outsole adhesive, can reduce annual emissions to the atmosphere of harmful solvent 20000 tons, so the project emission reduction benefits are very obvious," director Hong Maochun said.
According to the chairman of KELONG Yu Lin Jinxiang, KELONG Yu aqueous PU shoe adhesive has been applied in industrial production, products have been in Putian many shoe enterprises application, the business generally think the product sizing convenient, high bonding strength, in performance and can be comparable to the imported glue. Water PU glue consumption is very low, only the equivalent of oil products from 1/3 to 1/4, save manpower and smoke ventilation and fire fighting facilities. Practice has proved, application of water soluble products manufacturing industry, to the shoe not only environmental protection, high bonding strength, also truly reduce the comprehensive cost.
