Abstract

The invention belongs to the technical field of non-woven fabric manufacturing, and particularly relates to a non-woven fabric for cable production, which comprises the following components in parts by weight: 30-70 parts of a mixed fiber material, 10-20 parts of a hot-melt adhesive material, 8-15 parts of a flame-retardant additive and 1-3 parts of a water-blocking additive. On the basis of the raw materials, the waterproof additive and the flame-retardant additive are added, so that the material has very good flame-retardant and waterproof effects in the use process, the flame-retardant additive prevents a fire hazard caused by spontaneous combustion due to heat generated by high temperature when the wrapped cable is electrified for long-time work, and a very good safety guarantee is provided for the use of the cable; according to the waterproof cable, the waterproof additive plays a good role in protecting and isolating the internally wrapped cable, external water is prevented from permeating into the cable, cable faults are prevented, meanwhile, the waterproof cable has good ventilation and heat dissipation effects, the manufacturing method is simple in process, mechanical assistance can be utilized, operation and mass production are facilitated, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a non-woven fabric used for cable production and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Cables are usually composed of several or several groups of wires (at least two for each group) Twisted rope-like cables, each group of wires are insulated from each other, and are often twisted around a center, the entire outer surface is covered with a highly insulating covering layer, usually the outer surface of the cable is wrapped with non-woven fabric, The cable is protected, but the non-woven fabric used for the cable in the prior art has the following problems: [0003] In the prior art, the cable generates high temperature during the power transmission process, and the non-woven fabri...
