AI Technical Summary

Problems solved by technology

Because the traditional cables do not add fire-resistant ingredients in the material, the surface of the cable is easy to age over time. Once it is exposed to fire, it is easy to ignite and cause a fire, with serious consequences.

Abstract

The invention relates to a material formula for an insulating layer of a fireproof cable. The formula contains the following ingredients in percentage by mass: 8-14% of urea-formaldehyde resin, 10-15% of pentabromo ethylbenzene, 15-18% of liquid acid anhydride, 12-15% of mica powder, 16-20% of barite powder and 30-35% of asbestos. The formula has the advantages of reasonable material proportion, low cost and the like and has a fireproof function, and a guarantee is provided for the life and property safety of people.

Description

technical field [0001] The invention relates to the technical field of cable manufacture, in particular to a formula for a fireproof cable insulating layer material. Background technique [0002] As we all know, cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, and aluminum alloy cables. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. Because the traditional cables do not contain any fire-resistant ingredients, the surface of the cables tends to age over time. Once exposed to fire, they are easily ignited and cause a fire with serious consequences. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable formula with reasonable material matching, low cost and fireproof function, tha...
