Lightweight heat-resistant flame-retardant modified PVC resin compound-mixed cable material and preparation method thereof

Abstract

The invention relates to a cable material, in particular to a lightweight heat-resistant flame-retardant modified PVC resin compound-mixed cable material and a preparation method thereof. The cable material is prepared from, by weight, 55-65 parts of PVC resin, 30-40 parts of an ethylene-vinyl acetate copolymer, 0.01-0.02 part of tourmaline, 10-15 parts of expandable graphite, 5-8 parts of polytetra methylene ether glycol, 15-22 parts of aluminum silicate, 3-4 parts of eleostearic acid, 3-4 parts of hexamethyldisilazane, 22-30 parts of cotton pulp, 2-4 parts of zinc stearate, 14-18 parts of diethylene glycol dibenzoate, 8-10 parts of color master batch and 2-3 parts of an additive. The PVC resin and the ethylene-vinyl acetate copolymer are blended to serve as a resin base material, the cotton pulp subjected to modification treatment serves as a filler, and through the combination with the additive and other auxiliary raw materials for improving the machining performance and effect, the cable material can show more excellent heat-resistant flame-retardant performance than a traditional PVC resin when being used.

Description

technical field [0001] The invention relates to a cable material, in particular to a light heat-resistant and flame-retardant modified PVC resin compound 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...

[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 types of cable materials with balanced performance, environmental protection, safety, and strong practicability.
