Application of waste polycarbonate-furfurol thermolyzates to modification of petroleum bitumens
Abstract
Thermolysis of waste polycarbonate (PC) mixes with furfurol extract (EF) having various compositions, conducted for 3.5 hours at 270degreesC led to thermolyzates containing 95-80% by weight PC and 5-20% by weight EF. Thermomechanical and rheological properties as well as hardness and impact strength of the thermolyzates were determined (Tables 3 and 4). Increased EF content in the thermolyzate lowered softening and melting points; impact strength of thermolyzates is lower than for unmodified waste PC. PC-EF thermolyzate (up to 20% by weight) heated to 170degreesC with PS 85/25 asphalt leads to homogeneous compositions (Table 1). Increased content of the thermolyzate in the composition decreases softening and dropping point, as well as slightly increases brittleness; however, penetration of the composition is not altered (Table 5). Characteristics of the bitumen - PC-EF thermolyzate composition points to their possible application as binders in sealant/isolation materials for construction purposes.
