Problems solved by technology

However, most materials on the market can only meet one or two performance requirements at the same time, and cannot take care of many of them at the same time; while some high-end materials, such as polyurethane, can meet the performance requirements, but they are expensive and have special processing properties, making it difficult to use them in batches.

Abstract

The invention discloses a high-temperature-resisting and anti-freezing cable sheath material and a preparation method thereof, and relates to the field of cable sheaths. The sheath material is prepared from the following raw materials: cross-linked polyethylene, nitrile butadiene rubber, epoxy resin, polyester fibers, sodium acetonate, nano calcium carbonate, modified bauxite, polyphenylene sulfone resin, 2-amino-5-(p-methoxyphenyl)-1, a lubricant, a flame retardant, an anti-freezing agent and an adhesive. The preparation method of the high-temperature-resisting and anti-freezing cable sheath material comprises the following steps: carrying out three times of mixing on the raw materials and then carrying out vulcanization treatment. The cable sheath material disclosed by the invention is simple and convenient to prepare and low in cost; a finished-product cable sheath has excellent physicochemical properties and has the characteristics of high temperature resistance, cold freezing resistance and corrosion resistance; the cable sheath material is long in service life, has a wide application field and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of cable sheaths, in particular to a high-temperature and frost-resistant cable sheath material and a preparation method thereof. Background technique [0002] In recent years, due to the internal process of the natural environment and man-made external damage, the global climate has undergone great changes, frequent extreme weather, and severe weather such as heavy rain, snowstorm, and typhoon have occurred in many areas, and these have caused extreme heat or extreme cold. The climate makes the wires and cables in daily use have requirements for heat resistance and cold resistance. In the coastal area, the perennial sea wind and waves erode, the seawater is highly alkaline, and has certain corrosion damage to the cable material, thus putting forward requirements for the corrosion resistance of the cable material. For example, the cables used in wind energy generator sets must meet the strict low-temperature torsion ...
