Problems solved by technology

Traditional low-temperature-resistant PVC cable materials often need to add a large amount of plasticizer to achieve low-temperature resistance (low-temperature impact performance -40°C), but due to the addition of a large amount of plasticizer, the product is soft (generally Shore A hardness is around 70, Therefore, PVC products have high hardness and low temperature resistance, which is the technical bottleneck of PVC products.

At present, it is reported that the use of vinyl acetate/butyl acrylate/carbonyl terpolymer has good compatibility with PVC, good low temperature resistance, no preci...

Abstract

The invention discloses a PVC cable material for a 5G photoelectric composite cable. The PVC cable material comprises the following components in parts by weight: 100 parts of a PVC resin, 10 to 30 parts of trioctyl trimellitate, 1 to 30 parts of a vinyl acetate/butyl acrylate/carbonyl copolymer material, 1 to 30 parts of calcium carbonate, 0.1 to 0.2 part of polyethylene wax, 0.1 to 0.2 part of stearic acid, 2 to 5 parts of a calcium-zinc compound stabilizer, 1 to 5 parts of gamma-chloropropylmethyldiethoxysilane, 0.1 to 1 part of high-density oxidized polyethylene wax, 0.1 to 2 parts of oleamide and 0.1 to 10 parts of hydrotalcite. The PVC cable material of the 5G photoelectric hybrid cable is low in dielectric constant, can effectively reduce attenuation of optical cable signals in thehybrid cable, and can meet the requirements of an optical cable use environment of -40 DEG C to 105 DEG C.
