Abstract

The invention discloses a black 70 DEG C PVC (polyvinyl chloride) rodent-resistant cable sheath material, which comprises the following components in parts by weight: 100 parts of crushed waste PVC cable sheath material, 0-2 parts of PVC resin powder, 0-1 part of dioctyl ester, 0-0.5 parts of chlorinated paraffin, 0-0.5 parts of a composite stabilizer, 0-0.2 parts of bisphenol A, 0-0.3 parts of lubricant, 0.-0.5 parts of color masterbatch, and 2-3 parts of rodent-resistant masterbatch. After tests, all of the indicators of the 70 DEG C PVC cable sheath material disclosed by the invention exceed national standards, so that the PVC cable sheath material completely meets the use requirements of enterprises. The tested indicators are as follows: tensile strength>=15.0MPa, breaking elongation>=180.0%, low-temperature embrittlement impact temperature of -25 DEG C, volume resistivity at 20 DEG C>=1.0*10<8>ohm.m, thermally stable time at 200 DEG C>=50min, and protection rate of 100%.

Description

technical field [0001] The invention relates to a cable sheathing material, in particular to a black 70°C PVC rodent-proof cable sheathing material. Background technique [0002] At present, rats are one of the three major hazards that endanger plastic cables and optical cables. They cause many accidents every year and cause huge economic losses. Therefore, it is necessary to carry out research on recycled rat-proof sheathing materials. The existing rodent-proof sheath materials are all prepared from fresh materials, and cannot fully meet the requirements of non-toxic, harmless and environmentally friendly. With the rapid development of the economy, the wire and cable industry has become the second largest industry in my country, and the use of PVC cable materials is increasing, and the subsequent waste recycling and disposal issues have become urgent. The whole society is actively developing new technologies to recycle PVC waste. However, these technologies are still in t...
