Abstract

The invention discloses a low-smoke halogen-free flame-retardant polyolefin electric wire material for B1-grade power distribution wires, wherein the low-smoke halogen-free flame-retardant polyolefinelectric wire material comprises, by weight, 10-30 parts of an ethylene vinyl acetate copolymer, 10-20 parts of linear low density polyethylene, 5-10 parts of a compatilizer, 5-6 parts of an inorganicflame retardant, 2-5 parts of a shell forming agent, 2-5 parts of a smoke suppressant, 0.1-0.5 part of an antioxidant, and 0.5-1 part of a lubricating agent, wherein the inorganic flame retardant comprises first magnesium hydroxide subjected to surface treatment with an anionic surfactant and second magnesium hydroxide formed by performing surface activation on magnesium hydroxide by adopting a titanate coupling agent. According to the invention, no harmful substance is generated, the decomposed product can absorb a large amount of harmful gases and smoke generated by combustion of rubbers, plastics and the like while flame retardance is realized, and active magnesium oxide continuously absorbs incompletely-combusted molten residues, so that smoke is eliminated and molten drops are prevented while the combustion is quickly stopped; and the polyolefin electric wire material is good in flame retardant property and small in combustion smoke amount, and the fire disaster occurring environment causes little pollution to human bodies and air.

Description

technical field [0001] The invention relates to the technical field of electric wire materials, in particular to a low-smoke, halogen-free, flame-retardant polyolefin electric wire material for B1-level wiring and a preparation method thereof. Background technique [0002] With the advancement of science and the improvement of people's living standards, electricity is more and more closely related to our lives. Wire and cable are one of the necessary supporting products when using electrical products. They play the role of transmitting electricity, transmitting information and realizing electromagnetic energy conversion. effect. Wires and cables for civil buildings are mainly divided into two categories: cables and wires. Among them, the cables have a multi-core structure, and the structure design is relatively complicated. The structure can be used to complete the combustion level specified in the standard. Wires are usually of single-core construction, and the only way to...
