Abstract

The invention discloses a highly flame-retardant thermoplastic low-smoke halogen-free cable material in the technical field of cable materials. The formula of the cable material comprises the following raw materials in parts by weight: 120-150 parts of a resin, 80-100 parts of a flame retardant, 6-10 parts of a flame-retardant synergist, 1-3 parts of an antioxidant, 1-4 parts of a lubricating agent, 2-6 parts of a smoke suppressor and 3-5 parts of a silane coupling agent. The cable material has high flame retardant property and excellent thermoplasticity and can meet environmental protection characteristics of the material such as low smoke, free halogen and non-toxicity.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high flame-retardant thermoplastic low-smoke halogen-free cable material. Background technique [0002] With the acceleration of the country's modernization process, the power transmission and data transmission industry, which is the main development direction of the country in the future, is becoming more and more important, and its application scope and number of uses are also increasing year by year. Some existing cables are made of low-quality cable materials, and the cables have poor flame retardancy. When burned in a fire, a large amount of smoke and toxic gases will be produced, resulting in accidents of suffocation or poisoning casualties. Therefore, we propose a high flame-retardant thermoplastic low-smoke halogen-free cable material. Contents of the invention [0003] The object of the present invention is to provide a high flame-retardant thermoplastic low...
