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 relates to the field of a cable material, and in particular discloses an oil-proof and anti-corrosion polyvinyl chloride (PVC) cable material and a preparation method thereof. The oil-proof and anti-corrosion PVC cable material consists of the following components in parts by weight: 100 parts of PVC resin, 15-40 parts of rubber, 40-65 parts of a plasticizer, 30-55 parts of calcium carbonate, 5-12 parts of a heat stabilizer, 1.5-4 parts of a lubricant and 1-2 parts of an antioxidant. The prepared oil-proof and anti-corrosion PVC cable material disclosed by the invention is compatible with temperature resistance, cold resistance, oil resistance and corrosion resistance, and overcomes shortcomings of an existing material; the cable material is suitable for cold region and coastal region.

Description

technical field [0001] The invention relates to the field of cable materials, and specifically discloses an oil-resistant and anti-corrosion PVC cable material and a preparation method thereof. Background technique [0002] In recent years, due to natural internal processes 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 extremely hot or extremely cold climates , so that 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 test and at ...
