Degradable polyurethane foam came out

According to reports, the application of polymer materials is becoming more and more common, and the problem of "white pollution" of waste plastics has become increasingly serious. Various governments have formulated regulations to limit the use of non-degradable plastics. A few days ago, the project “Use of carbon dioxide to prepare aliphatic polyethylene carbonate and degradable polyurethane foam” undertaken by Jiangsu Yuhua Jinlong Technology Group Jinlong Green Chemical Co., Ltd. has passed the technical appraisal of relevant departments. Now, the aliphatic polycarbonates and polyurethane foams prepared by Chinese researchers using carbon dioxide as a basic raw material are completely biodegradable, and gradually replacing existing packaging materials such as polystyrene with it is an effective solution to “white pollution”. way.

The technology provider and researcher of the Guangzhou Institute of Chemistry, Chinese Academy of Sciences, said that the project uses the original and exclusive technology of the Institute, which uses carbon dioxide and epoxide as the main raw materials to prepare liquid aliphatic polycarbonate resins through polymerization, and further Preparation of degradable polyurethane foam. Copolymerization using macromolecule bimetallic complex PBM efficient catalytic technology, can freely control the molecular weight, the reaction conditions are mild, the reaction time is short, can effectively inhibit the side reactions, and ensure the quality of the resin.

The innovation of this project is also the original carbon dioxide activation technology, the original CO2 copolymer preparation technology with controlled molecular weight, and the optimized copolymerization reaction process; the prepared polyurethane foam can be completely biodegraded without leaving harmful substances and has high strength. High modulus characteristics, rich carbon dioxide units, easy to achieve flame retardant.
