Abstract


Abstract
This paper presents the development of plyboard using phenol–glue–formaldehyde (PGF) resin and their basic mechanical properties. Phenoplast and aminoplast-based resins is the important adhesive for the manufacturing of boiling water proof (BWP) grade, shuttering and moisture resistance plywood. Environmental concerns and higher cost of petroleum-based resins have resulted in the development of technologies to replace phenol partially by biomaterials for the manufacturing of resin adhesive. Natural bio-based materials such as tannin, CNSL (cardanol), lignin and soya etc. are used as partial substitution of phenol. Development of bio-based phenol–animal protein formaldehyde resin as exterior grade binder is not only cost effective but is noncorrosive also. Here about 30% of phenol was substituted by animal protein and optimized. The experimental results (as per IS: 1734 - 1983) of the physic-mechanical properties like surface finishing, tensile strength, internal bond strength, density, screw withdrawal and glue shear strength etc. of the ply board are quite satisfactory. This technique for the production of bio-based wood adhesive is cost effective, eco-friendly and could be an ideal solution of petroleum-based non-biodegradable resin adhesives.
