Problems solved by technology

However, due to the unreasonable ingredients of the traditional PVC cable sheath, the sheath has low tensile strength and poor toughness. In the actual use process, the cable will inevitably be bent or pulled, which will easily cause the sheath to be damaged. Cracked, unable to continue to protect the cable conductor wrapped in the sheath, and the service life is short

Abstract

The invention relates to a formula of a 70 DEG C cable sheath, which comprises the following ingredients in parts by weight: 48-52 parts of resin, 20-24 parts of calcium powder, 8.5-9.3 parts of p-phenylene, 11.5-12.5 parts of phthalate, 8.8-9.3 parts of liquid wax, 1.7-2.2 parts of stabilizer, 0.6-0.9 part of hard barium, 0.4-0.6 part of a composite additive and 0.4-0.6 part of a plasticizer. The 70 DEG C cable sheath has the advantages of reasonable material collocation and low production cost, the tensile strength of the sheath is improved, the tenacity of the sheath is improved, the sheath damage caused by bending and pulling in the actual use process is effectively prevented and the service life of the sheath is prolonged.

Description

Technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a 70°C PVC cable sheath formulation. Background technique [0002] The PVC sheath is a flat cable formed by wrapping multiple strands of copper wire conductors with insulating materials and pressing the sheath material through a high-tech automated equipment production line. It is flexible, flexible, thin, and small in size. , Simple connection, convenient disassembly, etc. The number and spacing of wires can be selected arbitrarily, making the connection more convenient, greatly reducing the volume of the product, reducing production costs, and improving production efficiency. It is suitable for data transmission cables or power transmission in electrical equipment. use. Common specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm and other flexible cables with various pitches. However, the traditional PVC cable sheath has low tensile strength and poor tou...
