Problems solved by technology

[0003] At present, domestic construction projects are developing rapidly, and the requirements for electrical equipment are getting higher and higher. Fires caused by electricity frequently occur, especially fires caused by wires and cables account for a considerable proportion. There are many types of wire and cable markets, but The performance of fire and flame retardancy is relatively weak. If the fire continues, the wire and cable will be easily burned through and cause a short circuit, which will cause even greater tragedies. As far as the current American market is concerned, the indicators for wire and cable are not only Simple insulation, tensile resistance, etc., and requires cables to have better comprehensive performance

Embodiment 1

[0024] Such as figure 1 and 2 The shown cable includes an insulated core group 5, and a tape 6 is provided on the outer periphery of the insulated core group 5; a flame retardant layer 4, a shielding layer 3, an inner lining 2 and a Outer sheath 1, the insulated wire core group 5 has multiple groups, each group is formed by twisting a plurality of insulated wire cores 5.1, and each insulated wire core 5.1 is made of a conductor 5.1-c and extruded outside the conductor 5.1-c The insulation layer 5.1-a and the water blocking tape 5.1-b are composed; the gaps between the insulated wire core groups 5 are provided with fillers 7;

[0025] The raw material components and parts by weight of the flame-retardant layer 4 are as follows: 40-50 parts of phenolic resin, 20-30 parts of magnesium hydroxide, 30-45 parts of high-density polyethylene, 2-4 parts of melamine cyanurate, 5-7 parts of fumed silica, 5-7 parts of Ca / Zn composite stabilizer, 2-3 parts of magnesium stearate, 5-10 part...

Embodiment 2

[0032] On the basis of embodiment 1, we also provide a kind of preparation method for preparing described cable, comprise the following steps successively:

[0033] (1) Wire-drawing and annealing the round metal wires to make conductors respectively, dip-coat the conductors in insulating varnish first, then extrude the insulating layer coated with a mixture of natural asphalt and pine tar in turn on the outside of the conductors, and insulate The water blocking tape is extruded outside the layer to form an insulated wire core, and multiple insulated wire cores are twisted together to form an insulated wire core group; the wrapping tape is wrapped around the outer circumference of the insulated wire core group and the filler is filled between the insulated wire cores ;

[0034] (2) Preparation of the flame retardant layer: First prepare the components according to the amount, pass the phenolic resin through the crusher to make phenolic resin particles with a diameter of less th...

Abstract

The invention relates to the technical field of cable processing, and particularly provides a cable which comprises multiple insulating wire core groups. A wrapping strap is arranged on the periphery of the insulating wire core groups, a flame-retardant layer, a shielding layer, a lining and an outer jacket are sequentially are outside the wrapping strap, each insulating wire core group is formed by winding multiple insulating wire cores, each insulating wire core is composed of a conductor, an insulating layer and a waterstop strap, each insulating layer and the corresponding waterstop strap wrap the outside of the corresponding conductor in an extruded manner, and fillers are arranged in gaps among the insulating wire cores. The cable is good in comprehensive performance, resistant to flame, wear, water, high temperature, oil and tension and high in flexibility. A production process provided is simple to manufacture and convenient to operate, production efficiency is improved for enterprises, and production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable and a production process thereof. Background technique [0002] At present, people's need for fast transmission of data and information, and their dependence on computers, word processors, teletype sensors and communication equipment have increased significantly and rapidly. The emergence of new technologies has made it possible to connect and network equipment in this area, leading to the comprehensive development of communication systems. The use of these systems has increased in specific areas such as high-rise buildings, ships, aircraft, trains, drilling platforms and mines. [0003] At present, domestic construction projects are developing rapidly, and the requirements for electrical equipment are getting higher and higher. Fires caused by electricity frequently occur, especially fires caused by wires and cables account for a considerable propor...
