Abstract
The present invention discloses an anti-flaming and buffering semiconductive water blocking tape for power cables, belonging to the field of power cables. The anti-flaming and buffering semiconductive water blocking tape for power cables comprises a base material structure layer, a material structure layer, an environmental protection polyester film and a mica tape. The base material structure layer is formed through uniform coating of non-woven fabrics or polyester fabrics in a pad dyeing mode; the material structure layer is prepared though adoption of rubbers and thermoplastic elastomers as a host; and the base material structure layer and the material structure layer are subject to calendaring for forming a semiconductive shielding and buffering water blocking tape. The present invention further discloses parts by weight of components for manufacturing the material structure layer. According to the invention, semiconduction shielding and uniiformity of an electric field are realized, and the purposes of buffering of mechanical stress, water blocking and flame retardation between an insulator and a metal sheath are realized.
