Water Based Rubber Adhesive "GB" Was Introduced To Fill Gaps In Domestic Industry Research

Recently, the national standard "waterborne polyurethane adhesive for shoes" was formally implemented by Hua Yu, Fujian science and Technology Development Co., Ltd.

With water as the carrier, the combination of its molecular structure as glue, no organic substances, and non-toxic environment-friendly adhesive standards has been implemented. It not only fills the gaps in China's waterborne polyurethane adhesives, but also is in the leading international level.

According to the introduction, the standard specifies the requirements, test methods, testing rules and requirements for marking, packaging, pportation and storage of waterborne polyurethane adhesives for shoes.

Waterborne polyurethane adhesives for shoes are water dispersive media without or containing only a small amount of residual organic solvents and no danger of explosion.

Compared with traditional solvent based adhesives containing large amounts of toxic and harmful, waterborne polyurethane adhesives for shoes have no toxicity, no smell, good initial adhesion and high peel strength for human and environment.

It is mainly used for the bonding of the sole and the side of the shoe, and has good bonding effect for most commonly used shoe materials. At the same time, the existing solvent based adhesive production line is not needed to be modified, and can be directly used on it.

For most of the shoe material, as long as the glue is brushed, the solvent type glue should be brushed two times.

According to the experiment of KELONG Yu company, the use of 1 tons of waterborne polyurethane shoe adhesive can reduce at least 1.5 tons of organic solvents.

"Shoe factories in Putian, the solvent based adhesives used in production contain poisonous and pungent odors, which are not environmentally friendly."

Hua Yu, a staff member of the science and technology development company of Zhongke (Fujian), and Lin Chao, a draftsman of the standard, said that the market for water based shoes adhesives has always been chaotic and mixed.

In response to the central call for the development of green products, improving the status of dirty smelly environment in shoe factories, standardizing the market.

Unified use

。

Since 2006, KELONG Yu has been working with various units to carry out experimental research on the product of the project. After eight years of painstaking research and development, the index of this standard was approved by the National Technical Committee for standardization of adhesives in December 1st this year.

Produced by Zhongke Hua Yu (Fujian) Technology Development Co., Ltd., the water-based polyurethane adhesives for shoes have been covered in various regions of Putian, and have been widely used in Guangdong, Zhejiang, Wenzhou, Quanzhou and other major provinces and municipalities.

Safety and innocuity is the biggest advantage of the waterborne polyurethane shoe adhesive for shoes, and is currently in the leading international level. The promotion of the use of waterborne polyurethane adhesive for shoes can not only improve the working environment of the shoemaking industry, but also has good economic benefits, environmental protection and social benefits.

Lin Chao said.

It is reported that the standard was put forward by the China Petroleum and Chemical Industry Federation, and KELONG Yu (Fujian) Technology Development Co., Ltd. took the lead, jointly drafted the Putian Haixi shoe research and design center, People's Republic of China entry-exit inspection and Quarantine Bureau comprehensive technology service center, Anhui University and other units.
