Abstract

The invention discloses a cable sheath moisture-proof additive and a preparation method thereof. The preparation method comprises the following steps: 1) ultrasonically shaking a molecular sieve, graphene, porous starch and water, and then drying to prepare a mixture; 2) soaking the mixture, nano-zinc dioxide and nano-tin dioxide, and then filtering to prepare the cable sheath moisture-proof additive. The moisture-proof additive can make a cable sheath have excellent moisture-proof performance. Meanwhile, the preparation method has the advantages of simple process and easy availability of rawmaterials.

Description

technical field [0001] The invention relates to cables, in particular to a cable sheath moisture-proof additive and a preparation method thereof. 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 sheath can meet the exis...
