Abstract

The invention mainly discloses a cold-resistance and flame-retardant level PVC (polyvinyl chloride) cable material. The cold-resistance and flame-retardant level PVC cable material is characterized by adopting 100 parts by weight of PVC as the standard and comprising the other following components in parts by weight: 20-22 parts of dioctyl phthalate, 16-18 parts of dioctyl terephthalate,4-6 parts of trioctyl phosphate, 4-8 parts of dioctyl sebacate, 12 parts of 52 chlorcosane, 6-7 parts of heat stabilizer, 8-10 parts of antimonous oxide, 6-8 parts of CP-70, and 16-20 parts of active CaCO3. The cold-resistance and flame-retardant level PVC cable material has the advantages that different from the common-level cable material, firstly, the mechanical performance and the ageing performance meet the requirements of GB / T8S15-2008; secondly, the low-temperature impact embrittlement performance is less than 50% in fracture at the temperature of below minus 36 DEG C; and thirdly the requirement for the oxygen index (OI) in the flame-retardant performance is more than 30%.

Description

technical field

[0001] The invention relates to a cable material, in particular to a cable material with polyvinyl chloride resin as the main material. Background technique

[0002] PVC cable material is a kind of plastic with polyvinyl chloride resin as the main body, adding necessary additives such as plasticizers, heat stabilizers, lubricants and fillers, etc., to mix, plasticize, pelletize and cool. particle. It is mainly used for the outer covering of wires and cables, and has good mechanical properties and electrical insulation properties. With the opening of the international market, the cable industry is advancing by leaps and bounds. Due to the different climates in different regions and different occasions, the requirements for the cables used are also different. For example, in the north of my country, Europe and other places, the temperature in winter is relatively cold, and the outer skin of ordinary cables is easily cracked, causing accidents such as short ci...
