EFFECTS OF ADHESIVES ON PHYSICAL AND THERMAL PROPERTIES ROOFING MATERIALS FROM OIL PALM EMPTY FRUIT BUNCH FIBERS USE AS A BUILDING MATERIAL

The objective of the study effects of adhesives on physical and thermal properties of roofing materials from oil palm empty fruit bunch fibers for use as a building material. The roofing sheet material is produced. Regarding the process of producing, they use synthetic adhesive PMDI), (UF) and resin (PF),3,5,7,9 and 11 wt%.and 15 mm. thickness. The researchers prepare to form the board by cold pressing method. They sprinkle the fiber with adhesives and other mixture into used as steel mold size of 300×320 mm then, they put the sheet on hot compressors set. Overall, PMDI synthetic adhesives had better physical properties than UF and PF synthetic adhesives, but the thermal properties of UF and PF synthetic adhesives were better than PMDI respectively. According to the study using three types of adhesives. The physical, testing density, moisture content, water absorption, thickness swelling and water permeability were measured according to JIS A 5908-2003, and TIS 535-2556. The thermal properties testing were used to test the thermal conductivity and thermal resistivity were done was according to ASTM C177-2010. Study and compare the properties of the 3 type synthetic adhesives that were tested according to related standards and methods. Able to pass the specified standards. It is an environmentally friendly product. It is a roofing material that reduces thermal conductivity and is a heat insulator. Suitable for use as a substitute for asbestos roofing materials
