USE OF LOW MOLECULAR WEIGHT LIGNIN TOGETHER WITH LIGNIN FOR THE PRODUCTION OF A PHENOL-FORMALDEHYDE BINDER COMPOSITION |
| 摘要 |
The present invention relates to a method for producing a binder composition, wherein the method comprises the following steps: (i) forming an aqueous composition comprising reactant components including lignin molecules of 11-60 lignin units, lignin molecules of 1-10 lignin units, polymerizable substance and crosslinking agent in the presence of a catalyst; and (ii) cooking the composition at a temperature of 60-95° C. for polymerizing the reactant components until a binder composition with a predetermined viscosity value is formed. |

1. A method for producing a binder composition, wherein the method comprises the following steps:
(i) forming an aqueous composition comprising reactant components including lignin molecules of 11-60 lignin units, lignin molecules of 1-10 lignin units, polymerizable substance and crosslinking agent in the presence of a catalyst, wherein the weight ratio of lignin molecules of 11-60 lignin units to lignin molecules of 1-10 lignin units is 0.1-20; and (ii) cooking the composition at a temperature of 45-95° C. for polymerizing the reactant components until a binder composition with a predetermined viscosity value is formed. |
