Thermodynamic properties of adhesive compounds on the basis of phenol-formaldehyde resin modified with the furfural-acetone monomer FA at the stage of mixing of the components have been determined. Physical-mechanical properties of wood chipboards on the basis of the modified adhesive compound and technological features of production are presented. It is established that the best physical-mechanical properties of wood chipboards are achieved with the introduction of 2–4 weight fractions of furfural-acetone monomer FA into the phenolformaldehyde resin with significant increase in strength, reduction in swelling, water absorption and the mass loss of plates during combustion. Physical-mechanical characteristics of wood boards on the basis of modified phenol-formaldehyde resin meet the requirements of GOST 10632–2014 “Wood Chipboards. Technical Specifications”; these boards surpass analogues on the basis of phenol-formaldehyde resins. At low expenditures for modification of the adhesive compound and insignificant changes in the technological process, the competitiveness of these boards improves.
