Problems solved by technology

The lowest temperature in winter in the northwestern alpine region is generally below -25°C, and even in some areas it reaches -40°C, such as the Inner Mongolia grassland and the Qinghai-Tibet Plateau, and the general equipment is in an unattended area. Cables working under such conditions should have Good low temperature resistance and certain flame retardant properties, general plastics and chlorinated polyethylene rubber materials cannot work normally at such low temperatures

Abstract

The invention discloses a cold-resistant cable sheath material as well as a preparation method and application thereof. The cold-resistant cable sheath material consists of the following raw materials in parts by weight: 72-80 parts of ethylene propylene diene monomer, 8-15 parts of sisal, 13-18 parts of fish scale powder, 20-26 parts of dimer fatty acid, and 35-46 parts of diisobutyl phthalate. The preparation method comprises the following steps: drying and crushing the sisal, adding anhydrous ethanol, and carrying out sealed treatment and microwave drying to obtain treated sisal; drying and crushing fish scales, adding anhydrous ethanol, and carrying out ultrasonic treatment and drying to obtain treated fish scale powder; and mixing ethylene propylene diene monomer with dimer fatty acid, carrying out ultrasonic vibration treatment, adding diisobutyl phthalate, and carrying out heat treatment on the treated sisal and the treated fish scale powder to obtain the cold-resistant cable sheath material. The cold-resistant cable sheath material disclosed by the invention has the advantages of excellent low-temperature resistance, flame-retardant performance and torsion resistance, has simple raw materials and a simple preparation process, and is suitable for cables in cold areas.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cold-resistant cable sheath material and its preparation method and application. Background technique [0002] A cable is usually a rope-like cable twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Highly insulating overlay. The cable has the characteristics of internal electrification and external insulation. With the rapid development of the economy, wires and cables are widely used in various industries and fields, especially in areas with bad climate, the requirements for cables are extremely high. my country's environment is complex and diverse, especially the areas with developed wind resources are mainly distributed in the northwestern alpine. The lowest temperature in winter in the northwestern alpine region is generally below -25°C, and even in ...
