Abstract

The aim of this study was the evaluation the Nano-silica and wood flour calcareous-treated and the properties of the wood plastic Nano composite obtained from these compounds. For this propose, wood flour was treated by calcium hydroxide and then combining with weight ratio of 60 to 40phc polypropylene and 4 per hundred compound (phc) MAPP was melt extruded. In addition nano silica at weight ratio of 0, 1, 3 and 5 phc was used. Wood plastic nano composites were fabricated by injection molding technique. fourier transform infrared spectroscopy was used to determine the wood flour changes after chemical treatment and for morphological study of nano composites, scanning electron microscopy and X-ray diffraction were used. Mechanical testes including bending (ASTM D790) and tensile (ASTM D638) and physical testes including water absorption and thickness swelling (ASTM D7031-11) on the samples were done. Results showed that by calcium hydroxide treatment, bending and tensile resistance were decreased but bending and tensile modulus were increased. Also with increasing the nano silica up to specific range, the mechanical properties were improved. Increasing the nano silica in untreated samples caused increasing of water absorption and in treated samples caused decreasing of water absorption. With increasing of nano silica, thickness swelling in the samples was decreased. The results of infrared spectroscopy showed that after lime treatment No change has occurred in the absorption band related to the hydroxyl groups. Results of scanning electron microscopy showed that the needle-shaped crystals of calcium hydroxide formed Calcium silicate crystals after addition the nano silica. As well as results of X-ray diffraction, confirmed Calcium silicate crystals.
