Study on Properties of PP Resin Composites Modified by Aluminum Powder

Abstract

The aluminum powder was used to blend with PP to impart a metallic luster to the PP matrix for achieving the effect of coating, and the ionic liquid (1-octyl-3-methylimidazolium tetrafluoroborate) was added into PP to improve the compatibility between aluminum powder and PP matrix. The results were analyzed by observing the different changes in thermal properties, crystallinity, rheological properties, mechanical properties, and sectional structures of the composite after filling different amount of aluminum powder. The results show that when adding 2phr aluminum powder, the crystallinity is high, the initial decomposition temperature of the composite is 2957deg;C, the shear viscosity is 61.52Pa•s, the tensile strength is 23.15MPa, and the hardness is 55.6N/mm2. In this ratio, the composite material has an outstanding performance.
