Abstract

The invention discloses a cable protector preparation formula which is composed of the following raw materials in parts by weight: 42-52 parts of chlorinated polyethylene, 8-12 parts of epoxidized natural rubber, 1-3 parts of antimonous oxide, 1-4 parts of a sulfonamide vulcanizing accelerator, 15-20 parts of nano calcium carbonate, 3-5 parts of zinc oxide, 1-4 parts of stearic acid, 2-5 parts ofethylene bistearamide, 0.5-1 part of dipentamethylene thiuram hexasulfide, 2-4 parts of a cross-linking agent, 2-5 parts of nano-silica, 0.5-1 part of pentaerythritol, 2-5 parts of carbon black and 3-7 parts of talcum powder. The protector has the characteristics of excellent heat resistance and improved tearing strength and resilience.

Description

technical field [0001] The invention relates to a preparation formula for a cable protective sheath. Background technique [0002] The cable is mainly composed of the following four parts. Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be twisted by a single wire or multiple wires; insulation layer: the insulation material used for cables should have high insulation resistance and high breakdown electric field strength, low dielectric loss and low dielectric constant. Sealing sheath: protect the insulated wire core from mechanical damage, moisture, moisture, chemicals, light, etc. For moisture-prone insulation, lead or aluminum extruded sealing sheaths are generally used; protective covering: used to protect the sealing sheath from mechanical damage. [0003] Although the existing sealing sheath can meet the existing requirements, the sealing sheath...
