| description | Reasonable use of waste rubber and plastic can avoid environmental pollution and improve composite materials performance. Recycled high density polyethylene (PE-HD), salix wood powder and waste tire powder were used as raw materials to prepare wood rubber plastic ternary composite materials (WRPC) by compression molding. The change rules of mechanical properties and heat resistance of WRPC were investigated under different heat oxygen aging time, and aging mechanism and surface topography were analyzed by FTIR and SEM. The study results indicate that heat oxygen aging reduces the mechanical properties of WRPC. After aging for 100 h, the retention rates of static flexural strength, elastic modulus, tensile strength and impact strength are 93.40%, 84.74%, 79.75% and 82.63%. The retention rates of storage modulus and loss modulus are 84.34% and 89.18%. Material rigidity and damping performance are all decreased. The vicat softening temperature and heat distortion temperature show an upward trend and then a downward trend. The ability of materials to resist external deformation is reduced. According to FTIR and SEM analysis, the oxidation reaction occurs on the surface of WRPC during aging. The carbonyl index shows an upward trend and then a downward trend. Cracks and holes appear on the surface of WRPC. |
