RAW MATERIAL FOR POLYURETHANE PRODUCTION AND ITS PRODUCTION FROM POLYURETHANE WASTE |
| abstract |
Raw materials for the production of polyurethane and the method of its preparation from polyurethane wastes, which are the product of the interaction of polyisocyanates with a polyether or polydiene polyol. Utilization of polyurethane using bioreagents, which are vegetable oil or fat, or a derivative of vegetable or animal oil or fat with hydroxy-functional groups, when a liquid product is obtained that has a markedly lower hydroxyl number. This makes it possible to use it as a raw material for the production of foamed and dense polyurethanes. With proper choice of bioreagent, the final functionality of the product, its hydroxyl number and reactivity, depending on the content of primary and secondary alcoholic hydroxy groups and amino groups, raw materials for the production of polyurethanes with optimal parameters are obtained in accordance with the required application. |
