Problems solved by technology

In other literatures and materials, various water-soluble fluorides and various fabric treatment liquids are also introduced to use water-repellent and oil-repellent methods. They also use the combination of dipping and rolling, but the curing effect is not good. , the consequences are either poor electrical performance, poor rinsing resistance, and poor abrasion resistance, or the cost of the treated rope is high or the rope is not soft and inconvenient to use.
The existing insulated wires still have the shortcomings of single performance and narrow application

Embodiment 1

[0034] At room temperature, add water to the dipping tank: 100 kg, commercially available TG521A fluorocarbon surfactant: 7 kg, melamine adhesive: 6 kg, KH560 silane coupling agent adhesive: 0.6 kg, catalyst triethylene tetra Amine: 1.2 kg, stir to mix all components evenly. Put 110 kilograms of fabric thread into it. After stirring and soaking for a period of time, take out the thread and put it in a centrifuge to dry it. The centrifuged liquid impregnating liquid can be adjusted according to the formula of the new impregnating liquid next time. The fabric thread contains about 25% impregnating liquid.

[0035] Heat the fabric thread in an oven, from room temperature to 60°C within 1 hour, then continue to heat up, to 80°C in 60 minutes, then to 100°C in 15 minutes, and to 200°C in the last 15 minutes . Immediately lower the temperature thereafter, and detect that the insulated wire of the obtained product is qualified, and the insulated wire has a solid content of about 3....

Embodiment 2

[0037] At room temperature, add water to the dipping tank: 100 kg, TG521A fluorocarbon surfactant: 5 kg, melamine adhesive: 4 kg, KH560 silane coupling agent adhesive: 2 kg, catalyst triethylenetetramine : 1 kg, stir and mix the components. Then add 100 grams of "Luming" luminescent pigment with a particle size of 20 microns. There are many commercially available products of this luminescent pigment to choose from and then stir evenly. Put in 100 kilograms of fabric thread, after dipping, take out the thread and dry it with a centrifuge. The fabric thread contains about 24% impregnating liquid. Heat the fabric thread in an oven, from room temperature to 60°C within 0.5 hours, then continue to heat up, to 80°C in 60 minutes, then to 100°C in 15 minutes, and to 200°C in the last 10 minutes . Then immediately lower the temperature naturally, and detect that the insulated wire of the obtained product is qualified. The product is luminous insulated wire, which lasts for more th...

Embodiment 3

[0039]The composition of the immersion liquid in the best manufacturing process of this patent is: water: 100 parts, fluorocarbon surfactant: 4-6 parts, binder: 2-3 parts, catalyst: 0.6-0.8 parts. The best embodiment is considered from the price-performance ratio. In general, the more fluorocarbon surfactants are added, the better the high-voltage resistance performance, and the more adhesives are added, the longer the high-voltage resistance of the product will be maintained. longer, but the price is higher. There are corresponding applicable products under the condition of maintaining the normal electrified voltage and weather conditions, and this embodiment can be used as general operating supplies. The performance of the product produced by this embodiment is particularly excellent. According to the IEEE-HVT "American National Standard - Live Work Trial Guide", the requirements for the insulating rope are: the length of the 250cm insulating rope is soaked in a water depth ...

Abstract

The invention includes following procedures. (1) Immersion fluid is prepared from water-solubility fluorocarbon surfactant, adhesive and contact agent. (2) Fabric thread is dipped in the immersion fluid at room temperature. (3) Picking off immersion fluid. (4) Solidifying. The continuous heating curve for solidifying procedure is from room temperature to 60 deg.C for 0.5-1 hr., 60 deg.C to 80 deg.C for 0.5-1 hr., 80 deg.C to 100 deg.C for 15 - 30 minutes and 100 deg.C to 200 deg.C for 10-15 deg.C. The constituent of immersion fluid is water 100 portions, fluorocarbon surfactant 3-7 portions, adhesive 2-7 portions and contact agent 0.5-1.2 portions. The invented rope, strip and cloth made from insulated threads reaches or exceeds the national standard of insulation property for hot-line work.

Description

technical field [0001] The invention relates to a multifunctional insulated wire for live work in the electric power industry and a manufacturing process thereof. Background technique [0002] During live work, especially high-voltage live work, the quality and performance of safety appliances are directly related to the smooth flow of lines and personal safety. The insulation performance of the ropes, operating rods and other equipment used is very high, and multifunctional tools are required for field operations in wet or rainy seasons. Among them, the rope is the most susceptible to moisture. The use of fluorine-containing compounds to treat ropes or fabric wires for making ropes has been widely used. The representative manufacturing process is such as the fluorine-containing copolymer emulsion treatment recorded on page 346 of the book "Fluorocarbon Surfactant". The process method of the fabric is to use 3-5% of the copolymer emulsion as the soaking liquid, use padding ...
