As society’s awareness of environmental protection gradually increases, the global demand for getting rid of dependence on petroleum resources continues to increase. This trend is driving the entire bioadhesive industry towards a circular economy. For example, solvent adhesives are turning to water-based or high-solids adhesives, while traditional polysaccharide and protein natural adhesive materials are also ushering in new development directions. By using cheap and renewable raw materials such as carbohydrates, proteins, lignin and tannins, it not only helps reduce dependence on petroleum resources, but also helps reduce environmental burden and promote sustainable development goals. This trend is of great significance in promoting the development of green and sustainable production methods, and brings potential innovation opportunities for future bio-based adhesive technology and market.
The research team of Associate Professor Gudrun Schmidt in the Department of Chemistry at Purdue University developed a bio-based adhesive and published it in "ACS Applied Materials & Published papers in the journal Interfaces. The adhesive developed by the research team is synthesized from corn protein and tannic acid, a protein extracted from corn. It has the advantages of bio-based sustainability, low raw material cost, and is stable underwater or in humid environments. of adhesiveness. Through further research and development, this adhesive can be used in the construction, industrial manufacturing, biomedical, dental, food and cosmetic industries, and can also be used in coral reef restoration to protect the marine environment.
The research team conducted relevant experimental verification of this adhesive in different environments and found that when tested in different types of water environments (seawater, salt water, tap water and deionized water), the adhesive still has strong bonding stability. And works better than traditional petroleum-based adhesives - its bond strength increases with exposure to water. The experimental principle is: when the adhesive is placed under water, a protective film will be formed on the surface to prevent moisture from immediately entering the interior of the material. These adhesives are easy to prepare and have high throughput efficiency, enabling large-scale production within hours.
Zhigeng analyzed the bio-based adhesive industry based on the think tank platform and found that the current situation of the adhesive industry is as follows: foreign application-oriented companies represented by IKEA are gradually transitioning from petroleum-based adhesives to bio-based adhesives, and are constantly changing from petroleum-based adhesives to bio-based adhesives. The downstream is pouring into the upstream, and it is committed to creating a whole industry ecology of bio-based adhesives. This means that the entire bio-based adhesive industry will next face a period of rapid growth from concept to practical application. Domestic enterprises should find out their product market positioning and continuously form their core competitiveness through technological innovation, marketing mix and market management. Zhigeng also looks forward to seeing more and more representatives of bio-based adhesive innovative companies, contributing to the innovative growth of the industry, and striving to create an upstream and downstream ecosystem that connects bio-based adhesive raw materials and applications.
