Modified thermoplastic polyurethane elastomer cable material doped with graphite fluoride and preparation method of cable material

Abstract

The invention relates to a cable material, in particular to a modified thermoplastic polyurethane elastomer cable material doped with graphite fluoride and a preparation method of the cable material. The cable material is prepared from, by weight, 5-8 parts of silica sol with the solid content ranging from 40% to 50%, 2-3 parts of methacrylic acid, 50-60 parts of thermoplastic polyurethane elastomer, 2-3 parts of ammonium dibasic phosphate, 20-30 parts of ethylene-vinyl acetate copolymer, 1-3 parts of alcohol alkoxylate, 15-18 parts of dioctyl phthalate, 0.2-0.3 part of graphite fluoride, 10-13 parts of magnesium silicide, 30-38 parts of sepiolite powder, 8-10 parts of color masterbatch and 2-3 parts of auxiliaries. According to the cable material, the thermoplastic polyurethane elastomer and the ethylene-vinyl acetate copolymer are mixed to serve as a resin base material, the sepiolite powder is loaded with the modified graphite fluoride to serve as a filler, the raw material use ratio is higher, and the reinforcement effect is prominent.

Description

technical field [0001] The invention relates to a cable material, in particular to a modified thermoplastic polyurethane elastomer cable material doped with fluorinated graphite 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. ...

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.
