Abstract

The invention belongs to the technical field of wires and cables and discloses a flame-retardant fireproof wire and cable material and a preparation method thereof. The flame-retardant fireproof wireand cable material is prepared from polypropylene resin, modified acrylic resin, methyl vinyl silicon rubber, tributyl citrate, nano silicon dioxide, dicumyl peroxide, platinic hydroxide, polyimide, zinc stearate, a silane coupling agent, white carbon black, an anti-aging agent and an accelerant, wherein a weight ratio of nano silicon dioxide to dicumyl peroxide to platinic hydroxide is (2.2-5.8):(1.5-3.6):(0.5-1.2). By adoption of a reinforcing system formed by nano silicon dioxide, dicumyl peroxide and platinic hydroxide, heat resistance and flame retardation of the flame-retardant fireproofwire and cable material are improved.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, and in particular relates to a flame-retardant and fire-resistant wire and cable material and a preparation method thereof. Background technique [0002] At present, with the rapid development of the electric power industry, the use of wires and cables has risen sharply. In 2010, the total output value of the industry reached more than 930 billion yuan, and the number of employees exceeded 720,000. In terms of scale, my country has become the world's largest producer of wire and cable. The rapid development and transformation and upgrading of the industry have brought about the desire for technological improvement and the development of high-safety wire and cable, especially the research and utilization of new wire and cable materials are of great significance to the development of the wire and cable industry. Since most of the wires and cables widely used in various sectors such as ind...
