Problems solved by technology

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 "Insulated Rope for Live Work". Invention is mainly to solve this problem

Embodiment 1

[0037] step one

[0038] Silkworm filaments are made into threads by doubling and twisting, dipped in acid dyes and dyed into orange to obtain a dyed core material; the acid used is 2 g / L of tannic acid, and the acid dyes are acid praline yellow GN, acid general One of common acid dyes such as Lahong B; its dosage is 1%-2% of the mass of silkworm filaments used. In order to facilitate industrial application, dyeing is generally carried out with a hank dyeing machine; when dyeing with a hank dyeing machine, the liquor ratio is controlled to be 1:10

[0039] step two

[0040] According to the mass ratio, after water-based polyurethane and / or polyacrylate:coupling agent=1:1-1:20 are mixed evenly, liquid B is obtained;

[0041] Place the dyed core material obtained in step 1 in liquid B, and after immersing at 80-100°C for 0.5 hours, a dyed core material with a transition layer is obtained; the liquid B is composed of a coupling agent and water-based polyurethane and / or polyacry...

Abstract

The invention relates to a damp-proof mulberry silk insulating rope for live working and a preparation method thereof, and belongs to the technical field of development and preparation of insulating ropes for live working. The insulating rope comprises a dyeing core material, a transition layer uniformly wrapping the dyeing core material and a water-proofing agent layer uniformly wrapping the transition layer; the water-proofing agent layer adopts a perfluorinated six-carbon water-proofing agent and / or perfluorinated four-carbon water-proofing agent. The production method comprises the steps that silkworm filaments are subjected to doubling and twisting to be made into threads which are dyed and processed to be orange through a dipping method with acid dyes, an aqueous polymer anionic emulsion of which the particle size ranges from 5 nanometers to 200 nanometers and a coupling agent are used for dipping method treatment, the fiber surface is anionized, dipping method cationic water-proof finish is conducted, high-temperature baking is conducted, and the threads are made into the rope; the damp-proof and insulating properties of the damp-proof mulberry silk insulating rope are far higher than the damp-proof and insulating properties in the prior art, the damp-proof mulberry silk insulating rope is particularly suitable for live working in a high-humidity atmosphere, storage and transportation are easy, and use is safer.

Description

technical field [0001] The invention relates to a moisture-proof mulberry silk insulating rope for live work and a preparation method thereof, and belongs to the technical field of development and preparation of insulating ropes for live work. Background technique [0002] At present, ordinary mulberry silk insulation 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 halfway It can’t work and must be dried in an oven before it can continue to be used; if it encounters rainy weather during live work and the insulating rope cannot be removed safely in time, it will cause great harm and loss to electrical equipment and directly threaten the power supply. Equipment and personal safety, this is a problem that has plagued the live-line work industry for a long time. [0003] Among them, the use of perfluor...
