$a Bonding of birch veneer with high moisture content using phenol-formaldehyde resin modified by soy protein $f Galina Jevgenivna Ortynska ...[et al.] 215 $c Obr., tab. 320 $a Lit. 330 $a The possibilities of gluing veneer of birch ( Betula pubescens Ehrh.) at moisture content of 15% with phenol - formaldehyde (PF) resins modified by soy protein isolate (SPI) 92% are examined in this paper . The amount of added modifying agent was 1 , 3 and 5 mass units on 100 mass unit of phenol - formaldehyde resin and pressing temperature of plywood was 130 or 150 °C . The influence of the soy protein isolate on the properties of the developed adhesive compositions (viscosity, pH, solid content , gelation time, pot life) and prepared plywood ( shear strength ) were evaluated . Pressing conditions of plywood were: pressure 1 . 0 MPa; time 6 minutes and during the last 30 seconds the pressure was lowered to 0 MPa; glue spread – 150 g/m 2 . It was found that the modification of phenol - formaldehyde resin by SPI allows to bond veneer at moisture content of 15%. Results indicated that the shear strength of plywood specimens glued at pressing temperature of 150 °C were higher than those glued at pressing temperature of 130 °C . However , the obtained values of the shear strength of the plywood were higher than the requirement (1 .0 MPa) of the standard EN 314 - 2 for exterior bonding quality 463 -1
