Problems solved by technology

The drastic change of temperature is a severe test for the material. At a certain high temperature, the performance of the cable material will change in one way or another, and some will even lose its use value. Therefore, if rubber is used as the material of insulation or sheath, if it is not Has a certain heat resistance, even if other properties are good, it cannot be used

Abstract

The invention discloses an insulated anti-interference rubber material, and belongs to the technical field of cables. The insulated anti-interference rubber material is prepared from the following components in parts by weight: 20-35 parts of cis-polybutadiene, 15-40 parts of butyl cyanogen rubber, 8-12 parts of liquid isoprene rubber, 7-9 parts of benzoxazine resin, 15-20 parts of attapulgite, 10-15 parts of carbon black, 3-8 parts of an activator, 1-2 parts of polyethylene glycol, 1-5 parts of polyethylene wax, 5-8 parts of a silane coupling agent, 20-30 parts of kaolin, 15-25 parts of modified auxiliaries, 5-12 parts of a plasticizer, 15-25 parts of light calcium carbonate, 10-15 parts of pottery clay and 5-9 parts of magnesium oxide. The insulated anti-interference rubber material is excellent in ultraviolet radiation resistance, is good in softness, has excellent physical mechanical property and flame resistance, is durable in use, lays a raw material foundation for developing anultraviolet radiation resistant power line sheath, and meets UL and European Union ROHS requirements, and is environmentally friendly.

Description

technical field [0001] The invention relates to a cable material, in particular to an insulating and anti-interference rubber material, which belongs to the technical field of cables. Background technique [0002] With the development of the wire and cable industry, people put forward higher and stricter performance requirements for cable products. The cable sheath is an indispensable intermediate structural part of the wire, which plays the role of protecting the power cord, ensuring the safety of the power cord, insulating the copper wire from water, air and other media, and avoiding leakage. However, when the existing power cord sheath is exposed to strong sunlight for a long time, it will become embrittled or even rupture, thereby affecting the performance of the power cord. [0003] Insulating glue is a multi-component composite glue with good electrical insulation properties. The main material is asphalt, natural resin or synthetic resin. It has a high viscosity at r...
