Problems solved by technology

[0004] However, compared with C8 fluorocarbons, reducing the length of the perfluoroalkyl chain will make the waterproof effect significantly worse, and also make the performance of the moisture-proof insulating rope unable to meet the national standard GB / T 13035-2003 "Insulating Rope for Live Work". Invention is mainly to solve this problem

Embodiment 1

[0038] step one

[0039] Polyester filaments are made into threads by doubling and twisting, dyed by dipping acid dyes, and then processed into orange-yellow, then taken out, washed, and dried to obtain dyed core materials; the dyes used are disperse dyes with anthraquinone structure; the dosage is 1.5% of silk mass. In this embodiment, a skein dyeing machine is used for dyeing; when a skein dyeing machine is used for dyeing, the liquor ratio is controlled to be 1:10.

[0040] step two

[0041] According to the mass ratio, after water-based polyurethane and / or polyacrylate:coupling agent=1:1 are mixed evenly, liquid B is obtained;

[0042] The dyed core material obtained in step 1 is placed in liquid B, and after immersion at 100°C for 1 hour, a dyed core material with a transition layer is obtained; the liquid B is composed of a coupling agent, water-based polyurethane and polyacrylate in a mass ratio of 1 : 1 composition; the general formula of the coupling agent is YSiX3...

Embodiment 2

[0050] step one

[0051] Polyester filaments are made into threads by doubling and twisting, dyed by dipping acid dyes, and then processed into orange-yellow, then taken out, washed, and dried to obtain dyed core materials; the dyes used are disperse dyes with anthraquinone structure; the dosage is 1% of silk mass. Adopt hank yarn dyeing machine to carry out dyeing in the present embodiment; When adopting hank yarn dyeing machine to carry out dyeing, control bath ratio is 1:20;

[0052] step two

Abstract

The invention relates to a dampproof polyester insulating rope for hot-line work and a preparing method thereof and belongs to the technical field of development and preparation of insulating ropes for hot-line work. The insulating rope comprises a dyed core material, a transition layer evenly covering the dyed core material, and a waterproof agent layer evenly covering the transition layer, wherein the waterproof agent layer is a perfluorocarbon-6 waterproof agent and / or perfluorocarbon-4 waterproof agent. The preparing method comprises the steps of conducting doubling and twisting on polyester filament yarn to obtain wires, conducing dyeing on the wires, taking the wires out, washing and drying the wires, treating the wires with water-based macromolecule negative ion emulsion with the particle size of 5-200 nanometers and a coupling agent through impregnation so as to achieve negative ionizing of the fiber surface, conducting impregnation positive ion waterproof treatment and high-temperature baking, and finally obtaining the rope. The dampproof insulating property of the rope is far higher than that of the prior art. The rope is especially suitable for hot-line work in a high-humidity environment, storage and transportation can be achieved more easily, and using is safer.

Description

technical field [0001] The invention relates to a moisture-proof polyester insulating rope for live work and a preparation method thereof, and belongs to the technical field of development and preparation of insulating rope for live work. Background technique [0002] At present, ordinary polyester insulating ropes used in live work in my country are prone to moisture, and cannot be used normally when the relative humidity is greater than 85%. Storage must be placed in a dry room, and moisture during transportation and use will cause failure in the middle The operation must be dried in an oven before it can continue to be used; if there is a sudden thunderstorm during the live operation and the insulating rope cannot be removed safely in time, it will cause great harm and loss to the electrical equipment, and directly threaten the safety of the electrical equipment. Personal safety is a long-term problem that has plagued the live working industry. [0003] Among them, the use...
