Mechanical and Morphological Properties of Cellulose and Polyol-Isocyanate Composites for Isolator
Polyol-isocyanate and cellulose are a material that are often used for insulation materials. The manufacture of composites polyol-isocyanate with cellulose is expected to produce a material that is stronger and more environmentally friendly. This study presents a insulation material of cellulose made from reeds imperata cylindrica type with the extraction process. The extraction of cellulose fibers to form a sheet by adding 3.5 % Na-CMC (Sodium Cellulose Carboksil Metyl). The production of the composite was made by pouring some polyol-isocyanate to a cellulose sheet and then put it into a cold-press and pressured for 90 minutes by varied pressures of 40517 N/m2 and 54022 N/m2. The sheets were then tested for their mechanical properties and morphology. The mechanical properties tested were tensile strength, and specific tensile strength. Specific tensile strength is a ratio of tensile strength and density. Meanwhile, the morphology was tested for the surface of material. The test showed minimal and maximal average tensile strengths were 9.1 MPa and 14.2 MPa, respectively, and minimal and maximal specific tensile strengths were 0.002 Mm and 0.013 Mm. Homogeneity composite occurred on 3rd mix with cold-press process at a pressure of 54022 N/m2.
