Production and properties of adhesives formulated from laccase modified Kraft lignin
(2013) In Industrial Crops and Products 45. p.343-348- Abstract
- Kraft lignin was used to formulate adhesives in combination with polyethyleneimine, chitosan and soy protein, respectively. The tensile strengths of bond lines formulated with laccase-treated and untreated lignin were found to be similar. However, a remarkable difference was noted when laccase-treated lignin was reduced by sodium borohydride prior to reacting either with chitosan or soy protein - decreasing the strength in the former case while increasing it in the other. Among the formulations, laccase treated and reduced lignin-soy protein adhesive exhibited more than half the strength of commercial polyurethane adhesive and retained 70% of its initial strength after two cycles of 1 h boiling and drying.
