Abstract

The invention belongs to the technical field of novel materials, and particularly relates to a high-strength flame-retardant cable material and a preparation method thereof. The cable material is prepared from the following raw materials in parts by weight: 80-100 parts of soft polyvinyl chloride, 5-15 parts of cobalt hydroxystannate, 5-12 parts of nano filler, 0.5-5 parts of a dispersing agent, 1-5 parts of a coupling agent, 3-5 parts of an organic tin stabilizer, 30-40 parts of dioctyl phthalate, 0.1-0.5 part of an antistatic agent, 2-6 parts of a lubricant and 1-5 parts of metal acetate. Asubmicron-size cobalt hydroxystannate flame retardant is prepared by a co-precipitation method, and the flame retardant can effectively inhibit continuous combustion of a cable material and inhibit generation of smoke dust in a combustion process only by a small adding amount, so that flame retardancy and smoke eliminating performance of the cable material are improved, and damage of physical performance of the cable material due to excessive adding amount of flame retardants is also avoided. Meanwhile, the nano filler is added, so that physical performance of the cable material is further improved.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a high-strength flame-retardant cable material and a preparation method thereof. Background technique [0002] The insulating material of the cable is mostly composed of rubber, and the rubber insulating layer can play the role of buffer insulation, but in the case of accidental fire, the rubber will decompose into flammable low molecular substances at high temperature, and the flammable low molecular substances will quickly Oxygen undergoes a violent oxidation reaction, and the oxidation reaction releases a large amount of heat, which will further promote the decomposition of the rubber. At the same time, the products in the oxidation reaction, such as low-molecular alcohols and aldehydes, will also undergo oxidation reactions with oxygen until the rubber burns out. [0003] Polyvinyl chloride (PVC) is one of the earliest industrialized production and one of th...
