"Solvent-free hot melt adhesive as environmentally friendly adhesive, the rise of the low-carbon economy facing rare opportunities for development. Improvement in the total amount at the same time, a visionary entrepreneurs and researchers should invest more low-carbon biodegradable products, the use of abandoned the plastic preparation of hot melt adhesives and other fields, to promote R & D and industrialization of new products. "at the end of the weekend, the Seventh hot melt adhesive technology and information exchange meeting, China adhesives industry Association Senior Advisor, Zhejiang University Professor Ye Shengrong appeal.
The senior scholars stressed that the low-carbon environmental protection has become the adhesive industry development mainstream, new varieties of hot melt adhesives are emerging, the prospects are very bright, but the capacity expansion is still the mainstream of industrial development. Right now, more low-carbon frontier domestic is rare cares. He predicted that it will soon become the world's hot spots, and called on the industry to invest as soon as possible, in order to achieve sustainable development.
Professor Ye three R & D direction.
First, biodegradable hot melt adhesives, refers to biodegradable polymer to alternative current application of the thermoplastic polymer as a hot melt adhesive matrix polymer, including poly lactic acid, polyester amides, polyhydroxy alkanoate and a natural polymer biodegradable hot melt adhesive. He introduced abroad has been on the type of material capable of protecting the environment to carry out a lot of research, but the application has not been perfect, the use of hot melt adhesive such as lignin, starch, bark prepared less stable, bonding strength needs improving. The domestic track related dynamic, actively carry out research and development work.
Second, the use of obsolete (old) plastic to develop a hot melt adhesive, example: nylon spent resin or recycled products, polyester waste resin, silk waste or recycled products can be prepared co polyamide and co polyester hot melt adhesive. He said: "The world is set off a wave of waste plastic recycling; China has also advocated the establishment of a resource-saving and environment-friendly society, so this studies significant economical use of resources and environmental protection.
Third, the aqueous dispersion-type, and a water-soluble hot melt adhesive, includes polyvinyl pyrrolidones, polyvinyl methyl ethers, polyesters. Especially in the paper industry in the extensive use of hot melt adhesive, it can make the application of hot melt adhesive articles more easily recycled.
