Low-smoke flame-retardant cable material

Abstract

The invention discloses a low-smoke flame-retardant cable material. The low-smoke flame-retardant cable material consists of the following raw materials in parts by weight: 10-15 parts of high-densitypolyethylene (HDPE), 10-12 parts of epoxy acrylate, 40-50 parts of plasticizer, 12-16 parts of chlorinated paraffin, 1-4 parts of silane coupling agent, 1-15 parts of environment-friendly calcium-zinc stabilizer, 12-15 parts of diisobutyl phthalate, 3-8 parts of scorch retarder, 5-15 parts of asarinin and 5-15 parts of dihydrocapsaicin. The cable material prepared by the low-smoke flame-retardantcable material has the characteristics of good weather resistance, low smoke, aging resistance and good flame-retardant performance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a low-smoke flame-retardant cable material. Background technique [0002] Wire and cable have the function of power transmission and information transmission, and play an important role in people's life and production. Designing and preparing low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials. It has been studied that the cable material material with good flame retardant performance, environmental ...
