High toughness and abrasion resistant PVC resin cable material and preparation method thereof

Abstract

The invention relates to a cable material, in particular to a high toughness and abrasion resistant PVC resin cable material and a preparation method thereof. The cable material is prepared from, by weight parts, 0.1-0.3 part of cerium oxide, 4-6 parts of tetraethyl orthosilicate, 18-25 parts of calcium bentonite, 1-3 parts of stannous pyrophosphate, 2-3 parts of zinc stearate, 50-60 parts of PVC resin, 6-8 parts of polyethylene wax, 2-5 parts of coumarone, 15-20 parts of isotactic polypropylene, 10-12 parts of trioctyl trimellitate, 5-8 parts of color concentrate, 15-20 parts of aluminium hydroxide, 6-8 parts of polytetrafluoroethylene micropowder and 2-3 parts of adjuvant. According to the cable material, the PVC resin is utilized as the basic material, high molecular materials, such as the isotactic polypropylene, the polytetrafluoroethylene micropowder and so on are auxiliary materials, the mechanical capacity and the processing performance of the PVC resin are improved, the raw material comprises compound filler made from calcium bentonite carrying the cerium oxide, the stannous pyrophosphate and the tetraethyl orthosilicate, and the good reinforcement function is brought into play.

Description

technical field [0001] The invention relates to a cable material, in particular to a high-toughness wear-resistant PVC resin cable material and a preparation method thereof. Background technique [0002] Cable material is a general term for plastics used for wire and cable insulation and sheathing. It is made of rubber, plastic, nylon and other materials as base materials, combined with auxiliary components such as plasticizers, fillers, color masterbatches, and antioxidants. Different types of cables and The use environment has different requirements on the performance of cable materials. Most of the commercially available cable materials are not resistant to scratches and folds, are easy to corrode and oxidize the internal metal wires, have poor flame retardancy, cannot balance hardness and toughness, and are highly toxic when burned. Defects such as resistance to humidity, cold and heat restrict the safety and service life of cables. Therefore, it is urgent to develop new...

Defects such as resistance to humidity, cold and heat restrict the safety and service life of cables. Therefore, it is urgent to develop new types of cable materials with balanced performance, environmental protection, safety, and strong practicability.
