Abstract

The invention discloses a flame-retardant wire and cable material. The material comprises components in parts by weight as follows: 100 parts of low-density polyethylene, 35-50 parts of EVA, 30-50 parts of bromine-containing epoxy resin, 5-15 parts of polyvinyl chloride, 20-40 parts of a flame retardant, 5-15 parts of an anti-aging agent and 60-80 parts of a cross-linking agent. With the adoption of the flame-retardant wire and cable material, the four base materials with certain content are selected and mixed together, so that mechanical properties of wires and cables are not damaged while the flame-retardant performance is excellent under the synergistic effect of the four base materials.

Description

technical field [0001] The invention relates to a flame-retardant wire and cable material and a preparation method thereof. Background technique [0002] Existing wire and cable materials are widely used in various industries due to their light weight, low price, excellent electrical insulation and chemical resistance, etc., but their poor flame retardancy can easily cause fires when making wires and cables. [0003] CN103351504 A discloses a flame-retardant wire and cable material, including the following components by mass: 100 parts of low-density polyethylene, 0.1-0.3 parts of coupling agent, 0.01-0.03 parts of vulcanizing agent, 30-40 parts of flame retardant, 10-20 parts of oxide, 1-3 parts of anti-aging agent, 60-80 parts of crosslinking agent, and 70-90 parts of oxygen index. The advantage of this invention is that it uses a new type of flame retardant and cooperates with advanced formula design to prepare a halogen-free flame-retardant wire and cable material, whic...
