The Quality Of Composite Board Made Of Waste Oil Palm Stem (Elaeis guneensis Jacq) and Recycle Polyethylene (PE)

Abstract

The main objective of this research was to find out the substitution of solid wood and it may solve environmental problem. These researches concerned on using waste ofoil palm stem particle form and recycle plastic polyetyhlene (PE) as raw materials for composite board In this research, 5% Maleic Anhydride (MAH) was added to increase compatibility and 0.75% Dicumyl Peroxide (DCP) was added to initiate the reaction of maleolation. The methods of this research followed JIS A 5908 (2003) with ratio ofplastic to particle were 50:50, 60:40 and 70:30, respectively, pressed at 30 kgflcm2 in 165 'Cfor 15 minutes. Evaluation on physical and mechanical properties based on JIS A 5908 (2003), and the result ofphysical properties as follow: I) Density met the standard at 0.77 -0.99 glcm, 2) The value ofmoisture content were below on target and the standard because ofthe hidrofobicity ofPE, the range were O. 79 -3.06%,3) Thickness swelling ofthe boardfor 24 hours fulfill the standard the value were 0.44 -2.77%. Vnforlunalelly the water absorption were 2.82 -16.19%. Mechanical properties consist ofmodulus elasticity (MOE), modulus rupture (MOR) and screw holding strength didn't meet the criteria ofJIS A 5908 (2003), except MOR with plastic: particle 60:40 with particle made of
