Key technologies for manufacturing and application of foamed water-based polyurethane passed acceptance

[China Packaging News] The National 863 Program project of "Key Technology for Manufacturing and Application of Foamed Waterborne Polyurethane" undertaken by Ketian Group, a high-tech enterprise in Gansu Province and a key investment company in Lanzhou New District, passed the technical acceptance organized by the Ministry of Science and Technology.

Experts from the acceptance group of the High-Tech Center of the Ministry of Science and Technology heard the self-acceptance report of the subject, reviewed the relevant acceptance documents, inspected the production site and conducted inquiries and discussions, and then from the aspects of completion of planned tasks, research innovation, and achievement of acceptance indicators. The implementation of the project was evaluated. The expert group believes that the research group has completed the research content specified in the mission statement, met the requirements of the assessment indicators and technical readiness level, and agreed to pass the technical acceptance.

The topic of " Key Technologies for the Production and Application of Foamed Waterborne Polyurethanes " was launched in March 2015. It was led by Waterborne Ketian and jointly participated by China University of Science and Technology, Anhui University, Hefei University of Technology and Shaanxi University of Science and Technology. Through the implementation of the project, key technologies such as molecular design and synthesis of water-based polyurethane resin, continuous production, mechanical foaming and control, water-based wet preparation of bass and production line design, etc. were solved, which solved the water-resistant polyurethane water resistance and poor mechanical properties, cell holes Technical difficulties such as temperature collapse, bass stripping load and unbalanced feel. Built ton aqueous polyurethane production line model and an aqueous wet Fabei Si exemplary production line 8, to achieve a large-scale application in the field of synthetic leather production and foamable aqueous polyurethane resin. 23 applications for invention patents , 11 of which were authorized. Presided over the formulation of 2 industry standards and participated in the formulation of 2 items. Published 19 papers and trained 21 graduate students .

The water-based polyurethane and water-based synthetic leather bass technology has become an industry development trend and will play an important role in both production and life. The achievements of the industry-university-research cooperation in this topic fully reflect the country's development needs, not just the publication of academic papers. The subject passed the acceptance, affirming the scientific research results achieved in the field of new materials technology in the industry-university-research cooperation model, and also confirming that Ketian is in The effectiveness of the work of " integration of production, teaching, research and application " . Future, water-based KLA-Tencor will continue to play a water-based polymer materials production and application expertise, to support research cooperation with universities in the water-based polyurethane synthetic leather and water-based technologies, and promote technological innovation to a new level, as the country's new materials Contribute to industry and talent construction.
