Buried anti-corrosion cable sheath material, and preparation method thereof

Abstract

The invention discloses a buried anti-corrosion cable sheath material. The buried anti-corrosion cable sheath material comprises, by weight, 11 to 13 parts of polyvinyl chloride, 15 to 30 parts of polytetrafluoroethylene, 20 to 25 parts of epoxy resin, 10 to 15 parts of polyurethane, 5 to 10 parts of acrylic acid, 40 to 60 parts of a composite organic solvent, 20 to 30 parts of a fire retardant, and 20 to 35 parts of a foaming agent. The invention also discloses a preparation method of the buried anti-corrosion cable sheath material. The preparation method comprises following steps: S1, weighing of raw materials; S2, preparation of a solvent; S3, mixing of basic raw materials; S4, adding of the solvent; S5, adding of the foaming agent; S6, moulding; and S7, cooling. The buried anti-corrosion cable sheath material possesses durability and fire resistance, is light in weight, and is promising in popularization prospect.

Description

technical field [0001] The invention relates to the field of cables, in particular to an underground anti-corrosion cable sheath material and a preparation process thereof. Background technique [0002] The existing cables have the following defects: 1. The general buried cable has poor fire performance, and it is easy to catch fire during storage or production, causing a fire and posing a safety hazard; 2. For the buried cable, its The anti-corrosion performance is poor, and the service life of the general cable is only about 10 years, and it needs to be replaced, while the replacement of the buried cable is very troublesome, labor-intensive and time-consuming; 3. The existing cable sheath is heavy, and it is very difficult to transport. It is laborious and needs to use a variety of transportation equipment, and because the cable itself is too heavy, it needs to consume more energy when laying, which does not meet the current social theme of energy conservation and environm...
