THE EFFECT OF MODIFICATION OF PHENOLIC RESIN WITH ALKYLRESORCINOLS AND H2O2 ON PROPERTIES OF PLYWOOD

Keywords: PF resin, alkylresorcinols, hydrogen peroxide, plywood
Abstract:

The study analysed the effect of modification of phenolic resin with alkylresorcinols and H2O2 on properties of softwood and hardwood plywood resinated with such modified PF resins. Conducted tests showed that the application of PF resin modified with alkylresorcinols makes it possible to manufacture plywood with improved properties, especially bond quality, than those of the control plywood pressed under identical conditions. In turn, the introduction of H2O2 both to pure PF resin and resin modified with alkylresorcinols improves properties of plywood as a result of enhanced reactivity and increased chemical adhesion of resin to wood. Moreover, applied PF resin modification methods make it possible to manufacture plywood with very good properties at pressing time reduced by 25%.
