Problems solved by technology

Cables for locomotives and vehicles have been working in harsh environments such as high temperature and oil pollution for a long time. The problems of traditional cable materials such as corrosion, aging, short-circuit leakage and fire in oil pollution have become increasingly prominent, resulting in an increasingly urgent demand for high-performance cable materials. Therefore, research In addition to meeting the most basic flame retardancy and electrical properties, a cable material that must also have good mechanical properties, oil resistance and corrosion resistance has very important practical significance

Abstract

The invention discloses an oil-resistant anti-corrosion PVC (polyvinyl chloride) cable material and a preparation method thereof. The oil-resistant anti-corrosion PVC cable material is prepared from the following raw materials in parts by weight: 85 parts of PVC resin, 10-35 parts of nitrile rubber, 2-5 parts of butyl stearate, 1-3 parts of lanthanum cyanurate, 30-50 parts of plasticizer, 3-8 parts of tris (2-chloroethyl) phosphate and 20-40 parts of filler. The raw materials are simple, the production cost is low, and the prepared oil-resistant and corrosion-resistant PVC cable material not only has good oil-resistant and corrosion-resistant performance, but also is excellent in mechanical performance and good in aging resistance, and can meet the requirements of cable materials in different use environments.

Description

technical field [0001] The invention relates to the technical field of cable material preparation, in particular to an oil-resistant and anti-corrosion PVC cable material and a preparation method thereof. Background technique [0002] PVC is a high molecular polymer obtained from vinyl chloride (VC) monomer through free radical addition polymerization. PVC and its products have many excellent properties, not only low price, mature processing technology, acid and alkali resistance, chemical resistance, wear resistance, but also high strength, good flame retardancy, electrical insulation and good transparency. It is used in many fields, such as profiles, films, flexible products and packaging materials. [0003] The common internal structure of cables includes core wire, insulating layer, shielding layer and sheath layer, among which the insulating layer and sheath layer are mostly PVC products. The formulation of PVC cable material contains a variety of ingredients, in addi...
