Inorganic Particles Reinforced Soybean-Oil-Based Polyurethane

摘要

Three series of inorganic particles modified polyurethane foams were prepared using soybean-oil-based polyols. The particles are mixture of SiO2 and Al2O3. The objective of this study was to compare the thermal and mechanical properties of the reinforced polyurethane with different particles content. The effect of ariation of particles loading from 0, 10, 20-wt% on the structure and mechanical properties were evaluated by Fourier-transform infrared spectroscopy, dynamic mechanical thermal analysis and tensile testing. The infrared spectra did not show any significant difference between the reinforced polyurethane and the pure polyurethane resin. The mechanical test results showed that mechanical properties such as compressive strength, tensile strength could be significant enhancement by introducing inorganic particles to the composite materials. The Tg results showed that the inorganic particles do not influence the basic mechanical of the Soybean-Oil-Based polyurethane thermal degradation but improve the thermal stability of the composites.
