Abstract
The invention discloses a moisture-proof cable sheath and a preparation method thereof. The preparation method includes the steps: 1) carrying out ultrasonic vibration of molecular sieve, graphene, porous starch and water, and then drying to prepare a mixture; 2) immersing the mixture, nano-zinc dioxide and nano stannic oxide, and then filtering to prepare a moisture-proof additive; and 3) mixingnatural rubber, polyvinyl chloride, dioctyl terephthalate, hydroxymethylstarch, bentonite, nano-titanium dioxide, silicone oil, sulfur and the moisture-proof additive, and molding to prepare the moisture-proof cable sheath. The cable sheath has excellent moisture-proof performance; and meanwhile, the preparation method has the advantages of simple process and easy availability of raw materials.
Description
technical field [0001] The invention relates to cables, in particular to a moisture-proof cable sheath 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 the softness of the cable under the conditions of laying and use, each core may be twisted from a single wire or multiple wires; sheath: the insulating material used as a cable 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 ...
