Abstract

The invention discloses a hydrophobic anti-oxidation electric power silicone rubber protection tube, and relates to the technical field of electric power cable protection tubes. The silicone rubber protection tube is prepared from the following raw materials: phenyl ether silicone rubber, 4,4'-dimorpholine disulfide, niobium yttrium tailings powder, high iron microbeads, hydroxy acrylic resin, 100,000 viscosity of hydroxypropyl methyl cellulose (HPMC), Pulisan PL-80, crosslinking assistant, a composite anti-aging agent, and a composite coupling agent. The protection tube provided by the invention has remarkable improvement in oxidation aging resistance, mechanical performance, electrical performance, flame retardancy and frost resistance, and better comprehensive performance, more extensive application fields, long service life and excellent practicability.

Description

technical field [0001] The invention relates to the technical field of power cable protection tubes, in particular to a hydrophobic and anti-oxidation power silicone rubber protection tube. Background technique [0002] The power cable is the carrier of power transmission and information transmission. The protective tube material is an indispensable outer structure part of the power cable, which plays a role in protecting the cable, ensuring smooth transmission of electrical / optical signals in the cable, and making the wire and cable The conductive alloy / optical fiber inside is isolated from water, air and other media to avoid damage, interference with external substances, or loss of transmission function, and prevent transmission performance from deteriorating. With the strengthening of people's awareness of environmental protection, many countries in the world have banned harmful components such as lead and cadmium in protective tube materials, and with the progress of soc...
