초록

In our study, the potential of rapeseed flour, which is a waste obtained in the production of bio-diesel or edible oil from rapeseed, as a raw material of wood adhesives was investigated. At first, rapeseed flour was hydrolyzed by distillated-water (DW-RFH), sulfuric acid (1%-SA-RFH, 3%-SA-RFH) and sodium bisulfite solutions (3%-SB-RFH). Secondly, phenol-formaldehyde prepolymers with different mole ratio of formaldehyde and phenol (F/P = 1.8, 2.1 & 2.4) were prepared as a crosslinking agent. Rapeseed flour-based adhesive resins was formulated with 70% RFH and 30% PF prepolymer at a solid weight basis. The adhesive resins were used for the fabrication of plywood panels, and then the shear strength and formaldehyde emission of the plywood panels were measured to examine the applicability of the adhesive resins for the production of plywood panels. The shear strength and wood failure of most plywood panels exceeded 0.6 N/mm2 and 50%, which is a minimum requirement of KS standard for ordinary plywood. The formaldehyde emission of the plywood panels fabricated with rapeseed flour-based adhesive resins formulated with 1.8-F/P PF prepolymer and DW-RFH or 3%-SB-RFH was less than 0.5 mg/L, which is E0 level specified in the KS standard. Based on the results, rapeseed flour can be used as a raw material for environmentally friendly adhesive resins, and consequently the application of the adhesive resins for the production of plywood panels might play an important part for the extensive use of bio-diesel by-product produced from rapeseed.
