Abstract

The invention relates to a chloroprene rubber sheath material used for cables and resistant to extreme cold. The chloroprene rubber sheath material is prepared from components in parts by weight as follows: 100 parts of CRSN322 resin, 4-5 parts of magnesium oxide, 36-40 parts of carbon black, 100 parts of calcined pottery clay, 20-25 parts of aluminum hydroxide, 4 parts of zinc oxide, 1.8 parts ofa vulcanizing agent, 5 parts of paraffin, 0.5-2 pars of stearic acid, 20-30 parts of a plasticizer, 2 parts of an anti-aging agent, 1 part of a silane coupling agent and 4-5 parts of a releasing agent. The preparation process comprises steps as follows: mixing, vulcanizing, sheet discharge and extrusion forming for preparation of the sheath material. The preparation method is simple, the steps are easy to operate, the prepared sheath material has excellent low-temperature bending performance, low-temperature impact property, shore A hardness and flexibility, and produced and manufactured cables can be used in extreme cold regions at subzero 60 DEG C for a long time.

Description

Technical field [0001] The invention relates to an extremely cold-resistant chloroprene rubber sheath material for cables, and belongs to the technical field of the preparation of cable rubber materials. Background technique [0002] In recent years, the wind power industry, Antarctic scientific research, refrigerated indoor robots and other fields have developed relatively rapidly. However, these areas are often in extremely cold areas and the working conditions are extremely harsh. To ensure the safe operation of the power system, the cables used are The extreme cold resistance of -60℃ is required, and the demand for extreme cold cables is increasing. Cables made of conventional rubber sheath materials have a minimum temperature resistance rating of only -40°C. When used in extreme cold areas at -60°C, the surface of the cable sheath will have different degrees of cracking and embrittlement, and the flexibility will become poor, which will seriously affect the service life and...
