Abstract

The invention discloses a light-resistant PVC cable, and belongs to the field of cables. The light-resistant PVC cable comprises the formula of the following weight ratio: 100 parts of PVC, 20-30 parts of DOP, 15-30 parts of DOS, 5-7 parts of TCP, 3-10 parts of T-50, 1-5 parts of lead sulfate tribasic, 3-8 parts of dibasic lead phosphite, 0.1-0.5 part of dibasic lead stearate, 0.5-1 part of barium stearate, 0.1-0.2 part of bisphenol A and 0.1-0.2 part of UV-529. The cable is mainly applied to the field of power generation, metallurgy and petrochemicals, the cable core is firm and the cable is high-temperature-resistant, oil-resistant and acid-resistant, tension-resistant and anti-oxidation, and the cable also has high ultraviolet protection capacity and the ultraviolet shielding rate can be 96.7%.

Description

technical field [0001] The invention belongs to a cable material, in particular to a light-resistant PVC cable. Background technique [0002] At present, with the development of solar technology, solar energy has been applied to more and more fields, but because of the strong ultraviolet radiation that comes with the areas rich in solar energy resources, cables have been exposed to sunlight for a long time, and the external extrusion is relatively strong. It is used in the environment, and its drag resistance is not enough, the high temperature resistance strength is not enough, it is prone to mechanical damage, skin peeling and other phenomena, there are great hidden dangers to the safe use of the main equipment, and people want to apply solar energy to cables. This difficulty must be overcome. Therefore, higher requirements are put forward for the anti-ultraviolet performance, high temperature and fire resistance performance of the cable, and the firm performance of the c...
