Abstract
The present invention relates to a phenol-based resin adhesive from lignin pyrolysis, comprising a polymer of phenol and formaldehyde from lignin pyrolysis, wherein the phenol from lignin pyrolysis comprises at least two phenols from lignin pyrolysis or at least two lignin-modified phenols from lignin pyrolysis. A repeat unit of the polymer of phenol and formaldehyde from lignin pyrolysis comprises at least two phenol units from lignin pyrolysis or at least two lignin-modified phenol units from lignin pyrolysis. According to the phenol-based resin adhesive from lignin pyrolysis in the present invention, by-products during the pyrolysis of lignin for power generation are used as raw materials, so it is environment-friendly and economical.
