A Novel Phenol – Based Composite Production: Features and Characterization

Abstract:

The aim of this study is to investigate on manufacturing new tannin phenol-formaldehyde resin as adhesive in paulownia composite. For this purpose, renewable tannin was introduced in the classic adhesive formulation in order to supply a part of phenol–formaldehyde (PF). Variables were substituted tannin with phenol at two levels (0%, 10 % and 20%) and press temperature (150Co and 170Co). plywood panels were manufactured in laboratory. Mechanical (MOR and MOE and) and physical (TS and WA) properties of panels were evaluated according to ASTM standard. Data collected based on factorial design and using SPSS software were analyzed. The Results showed that substitution tannin with phenol had slight effect on mechanical properties but when press temperature increased mechanical properties were improved. Physical properties of plywood panels bonded with tannin–PF resins (20:80) were better than plywood panels PF made.
