| Abstract: | The reactions of isocyanate with alcohol or water are the key basic reaction for isocyanate bonding to wood. The reaction rules of isocyanate with alcohol or water in room temperature in which some factors were discussed such as the concentration of alcohol and isocyanate, the mole ratio, acid, alkali, solvent, temperature. A new mechanism, Alcohol Polymer Reacting Mechanism was put forward to explain the reaction kinetics of isocyanate with alcohol. And experiments proved that the reaction rules of isocyanate and water could be described by the second order equation. |
