Abstract

This research aimed to investigate the effect of CHEMICAL TREATMENT OF WOOD FLOUR on some physical, mechanical and morphological properties of wood-plastic composite. CHEMICAL TREATMENT OF WOOD FLOUR at 7 levels i.e. without treatment, acetylation, benzoylation, mercerization, magnesium hydroxide, calcium hydroxide and warm water treatment were considered as variable factors. To evaluate the reaction of wood flour with chemical materials, WEIGHT PERCENT GAIN (WPG) were calculated. After chemical treatment, wood flour and polypropylene were mixed with weight ratio of 60 to 40 and 4 per hundred compound (phc) of coupling agent in the extruder and then the specimens were fabricated by injection molding method. Mechanical tests including tensile, flexural and impact strength and physical examination, including water absorption and thickness swelling was performed on specimens according to ASTM standards. Moreover, to study the MORPHOLOGY of the composites, scanning electron microscopy (SEM) was used. The results showed that the mechanical strength increased and physical properties such as water absorption and thickness swelling decreased after chemical treatment. As a result of chemical treatments, the weight of wood flour increased while the highest value was of the benzylation treatment. Results of SEM showed an improvement in cross linking between fibers and polymeric matrix due to the chemical treatment, in a way that in treated samples, exiting of fibers out of the matrix was not observed.
