Problems solved by technology

Therefore, it is generally used as the insulation layer of low-voltage (≤1KV) and medium-high voltage (6~10KV) cables. PVC plastic is also widely used due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance and good water resistance. As the sheath material of wires and cables, heat-resistant (105°C), cold-resistant, oil-resistant, flame-retardant, extra-soft and non-toxic PVC can be produced by adding special performance additives or modifiers. Cable materials to meet the needs of special wire and cable products; however, heat resistance and cold resistance cannot be unified, and generally in order to ensure heat resistance, the insulation will decrease, and the performance in terms of hardness, tensile strength and elongation is not equal. not perfect

Abstract

The invention relates to the field of cables and concretely relates to a PVC cable material formula. The PVC cable material formula comprises, by weight, 98-102 parts of PVC resin, 3.6-4.4 parts of a stabilizing agent, 18-22 parts of a plasticizer, 5-7 parts of a filler, 17-19 parts of a lubricant, 1-1.4 parts of an anti-oxidant and 4-6 parts of a coloring agent. The PVC resin is loose PVC resin obtained by a suspension method. The stabilizing agent is calcium carbonate. The plasticizer is dioctyl adipate. The filler is calcined clay. The lubricant is chlorinated paraffin. The anti-oxidant is a mixture of lead stearate and calcium stearate. The coloring agent is a mixture of tribasic calcium sulfate and dibasic phosphorous acid. The PVC cable material formula improves low temperature resistance of a cable material. Through a mixture of lead stearate and calcium stearate, low temperature resistance of the cable material is improved, weatherability is good and hardness, tensile strength and elongation are greatly improved.

Description

technical field [0001] The invention belongs to the field of cables, and more specifically, the invention relates to a PVC cable material formula. Background technique [0002] The withstand voltage and insulation resistance of PVC cable material are relatively high, but the dielectric constant and dielectric loss are relatively large. Therefore, it is generally used as the insulation layer of low-voltage (≤1KV) and medium-high voltage (6~10KV) cables. PVC plastic is also widely used due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance and good water resistance. As the sheath material of wires and cables, heat-resistant (105°C), cold-resistant, oil-resistant, flame-retardant, extra-soft and non-toxic PVC can be produced by adding special performance additives or modifiers. Cable materials to meet the needs of special wire and cable products; however, heat resistance and cold resistance cannot be unified, and generally in order to ensu...
