Abstract

In recent years, with the rapid development of China's wire and cable industry, optical cable demand gradually increased, but the wire and cable water resistance is not good, and vulnerable to corrosion caused by the distortion of the optical signal, so the cable aluminum-plastic composite belt should be born. In this study, The aluminum-plastic composite tapes were hot-pressed with low density polyethylene (LDPE) or metallocene linear low density polyethylene (MLLDPE) and high density polyethylene (HDPE) to test their heat sealing strength and mechanical properties. The rheological study shows that the HDPE/MLLDPE blends and HDPE/LDPE blends have a linearity in the lgG'-lgω curve in the low frequency region, and the heterogeneous system is in the molten state. The tanδ value of the blends gradually increased with the increase of the MLLDPE content, which indicated that the viscosity of the blends became higher, which improved the process ability of blends. The TGA blend shows that HDPE has better heat resistance. The melting point of HDPE in HDPE/MLLDPE blends decreased with the increase of MLLDPE content, which indicated that the two had mechanical compatibility. In the HDPE/ LDPE blends, two melting peaks were found, which indicated that the HDPE and LDPE had different crystal structure compatibility, and they were more likely to crystallize separately.
