Abstract

The invention relates to the field of cable preparation, in particular to a wear-resistant PVC cable and a preparation method thereof. The wear-resistant PVC cable comprises a conductive cable core and an outer protective sheath; the outer protective sheath is used for coating the conductive cable core, and comprises following components, by weight, 75-90 parts of PVC resin; 25-30 parts of calciumcarbonate; 8-12 parts of tree ash; 2-10 parts of a silane coupling agent; 20 to 30 parts of dioctyl phthalate; 10 to 15 parts of rubber powder; 5-8 parts of a halogen-free flame retardant; and 0.5 to1 part of an antioxidant. The preparation method of the wear-resistant PVC cable comprises the following steps: S1, weighing the raw materials; S2, stirring and mixing the raw materials weighed in the step S1 to obtain a mixture; S3, extruding and granulating the mixture obtained in the step S2 to obtain an outer protective sheath master batch; and S4, melting and extruding the outer protective sheath master batch, coating the peripheral side of the conductive cable core with the outer protective sheath master batch, and cooling and curing to obtain the wear-resistant PVC cable.

Description

technical field [0001] The invention relates to the technical field of cable preparation, more specifically, it relates to a wear-resistant PVC cable and a preparation method thereof. Background technique [0002] Cables are generally made of one or more mutually insulated conductive cores and outer sheaths, and are used to transmit power or information from one place to another. With the rapid development of the economy, more and more places need cables to transmit power or other information, so there are stricter requirements for the manufacture of cables. The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and insulating the copper wire from water, air and other media to avoid leakage. [0003] Among them, the wear resistance of the cable sheath is a very important performance index, especially for PVC cables, its wear resistance is low, which directly affects the ...
