Abstract

The invention discloses a low-energy-consumption, high-flame-retardancy, low-smoke and halogen-free cable material which comprises the following components in parts by weight: 50-100 parts of polyethylene, 50-100 parts of polyethylene graft copolymer, 20-60 parts of a compatilizer, 180-250 parts of an efficient flame retardant, 0.2-5 parts of an anti-oxidant, 5-40 parts of a high dispersant, and 1-10 parts of a silane coupling agent. According to the invention, the problems that the conventional flame-retardant cable material is low in extrusion efficiency and overhigh in energy consumption; besides, the cable material has the characteristics of being environment-friendly, low in smoke and nontoxic.

Description

technical field [0001] The invention relates to a cable material, in particular to a low-energy, high-flame-retardant, low-smoke, halogen-free cable material. Background technique [0002] With the rapid development of the domestic cable industry, conventional cable materials can no longer fully meet the increasingly diverse needs of cable factories. In order to meet high flame-retardant requirements, the amount of flame retardant added to current cable materials is too large. During the cable extrusion process, the current extrusion is too high, and the extrusion speed is too slow and the energy consumption is too large. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a low-energy, high-flame-retardant, low-smoke, halogen-free cable compound with good flame-retardant properties and low energy consumption during extrusion. [0004] Technical solution: In order to achieve th...
