Water-Based Shoe Glue: Let Shoe Making Industry No Longer Be "Invisible Killer" Of Environmental Pollution.

China's shoe making industry has always been the "worst hit area" of pollution. The traditional mode of production with high energy consumption and low output not only wastes many resources, but also destroys the environment in tangible or intangible ways.

In the face of increasingly severe environmental pollution, shoe manufacturers must pay attention to the selection and use of adhesives for production materials in the course of operation.

During the "12th Five-Year" period, as the state attaches great importance to energy conservation and emission reduction, the relevant laws and policies are becoming more and more perfect, and people's awareness of their health is gradually improving.

It is known as environmental pollution.

In the shoemaking industry, the shoes are discharged from the production process.

The harm of matter to human body is not to be underestimated.

As a result, the environmental protection of water based shoes glue has begun to enter the field of vision. How about the future and development process of this water-borne shoe glue? This is the answer to Hong Maochun, academician of the Chinese Academy of Sciences and director of the Fujian Institute of material structure.

According to director Hong Maochun, most of these organic solvents are volatile organic compounds. In addition to the occupational diseases caused by direct contact, the organic solvents are produced in large quantities. The organic solvents emitted in the atmosphere produce photochemical reactions under the action of ultraviolet radiation, and produce two pollutants, such as ozone and aldehydes. When adverse weather conditions are encountered, these pollutants will form photochemical smog, and photochemical smog will stimulate the eyes and respiratory tract of human beings, causing headache, eye swelling, laryngitis, lung diseases, and many other respiratory diseases.

After analyzing the adhesive market, the experts concluded that the environment-friendly adhesive with good quality and no pollution and being in line with international standards is gradually becoming this.

The waterborne polyurethane shoe adhesive developed by the Fujian Institute of material structure of the Chinese Academy of Sciences and KELONG woo Fujian Technology Development Co., Ltd. has the characteristics of no organic solvents, strong adhesion, no toxicity, no smell, no explosion hazard, no pollution, friendly to the body and environment, and is not easy to damage the surface of the coated shoes. It is suitable for bonding materials easily eroded by organic solvents. It is a widely used shoe adhesive in developed countries.

For shoe factories, green manufacturing is the general trend.

The environmental protection and high performance waterborne polyurethane adhesive for KELONG shoes, which is mainly developed by KELONG woo, adopts polyurethane polymer design technology and strong shear self emulsifying technology. The self-developed sulfonate type hydrophilic chain extender is used to develop the formulations, preparation processes and testing methods of sulfonate and carboxylate type two waterborne polyurethane shoes.

The product has been successfully applied to the bonding of a variety of shoe materials, replacing the traditional oil-based shoemaking containing benzene glue. Compared with imported PU shoes, the cost is lower.

"It is estimated that if the whole province uses 2 billion pairs of shoes every year, it will reduce 20 thousand tons of harmful solvents to the atmosphere by using waterborne polyurethane soles, so the emission reduction benefit of this project is also very obvious," director Hong Maochun said.

According to Lin Jinxiang, chairman of KELONG Yu, China KELONG water PU shoes adhesive has been industrialized. The products have been widely applied in many shoe factories in Putian. Generally speaking, the products are considered to be convenient to use glue, high in adhesive strength, and comparable to imported glue in various performance indexes.

The unit consumption of waterborne PU adhesive is very low, which is only equivalent to 1/3 to 1/4 of oily products, saving manpower and ventilation and fire fighting facilities.

Practice has proved that the application of water-based products to footwear manufacturing industry is not only environmental protection, high adhesion strength, but also reduces the comprehensive cost.
