Abstract
The invention relates to a preparation method of modified aramid fibers. The method comprises the following steps that aramid fibers are impregnated in a mixed treating solution to be treated, and the temperature of the mixed treating solution is controlled to range from 100 DEG C to 130 DEG C, wherein the mixed treating solution is obtained by mixing a waterborne polyurethane and polyacrylate nano composite emulsion with a silane coupling agent; the aramid fibers are taken out of the mixed treating solution and impregnated into a perfluorinated six-carbon-chain waterproofing agent added with cationic dye to be treated, and the temperature of the perfluorinated six-carbon-chain waterproofing agent is controlled to range from 100 DEG C to 130 DEG C; the treated aramid fibers are baked, and the modified aramid fibers are obtained. The prepared fibers and a prepared insulating rope have the advantages of being resistant to damp and ultraviolet aging, high in strength and the like. The preparation method has the advantages of being simple in process and convenient to operate, industrial large-scale production can be conducted to produce qualified products, and storage and transportation of damp-proof insulating ropes prepared from the modified aramid fibers are easier and safer, and use is safer.
Description
Technical field
Technical field of polymer materials of the present invention, live line work insulating rope be specifically related to a kind of modification of aramid fiber, using this fiber to make and preparation method thereof.
Background technology
At present, on market, insulation ropes is mainly woven by silkworm silk or synthetic fibers, strand system forms.In livewire work field, it is contemplated that to the insulating properties of rope and the requirement of the morphotropism of rope, main use silkworm silk rope, Sythetic fiber rope.Owing to the damp-proof treatment of silkworm silk rope and Sythetic fiber rope is generally adopted by the physical attachment of anti-blushing agent, and non-bonding connects, and after causing washing certain number of times, its humidity resistance declines significantly, causes its service life short.And, erection along with UHV transmission line, the volume and weight of each gold utensil on transmission line of electricity increases the most therewith, during livewire work, need gold utensil is carried out lifting, the intensity of existing silkworm silk rope and Sythetic fiber rope can not meet the needs of livewire work the most, causes some events in operation to carry out smoothly.Accordingly, it would be desirable to develop new livewire work insulation ropes, compared to silkworm silk rope and existing Sythetic fiber rope, its humidity resistance is more longlasting, stable, and intensity is higher, and has higher resistance to UV aging.The large-tonnage stress of livewire work project on tower can be transferred to ground by novel high-strength, protection against the tide, the insulating cord of anti-ultraviolet ageing, reduce the labor intensity of operating personnel on shaft tower, ensureing the safety of operation, succeeding in developing of this insulating cord will bring third time revolution for extra-high voltage electrified operation.
Aramid fiber, i.e. PPTA, be a kind of novel high-tech synthetic fibers, by the aramid fiber molecule crystalline texture high polymer with cross-linked network being similar to rigidity extended chain, it may have typical skin, core structure model.There is superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight equally.Its intensity is 5～6 times of steel wire, and toughness is 2 times of steel wire, and weight is only the 1/5 of steel wire；At a temperature of 560 DEG C, do not decompose, do not melt；There is good insulating properties and ageing resistace.It is widely used in Aeronautics and Astronautics, national defense industry, auto industry, heat-resisting and protective clothes, making cord, sports equipment and the reinforcement of composite.
In view of the excellent mechanical property of aramid fiber and heat stability etc. so that it is become the first-selected candidate material of livewire work insulating cord.But, there is the problem of humidity resistance difference in aramid fiber, after making moist, its mechanical properties decrease is fast, and the performance of its anti-ultraviolet ageing also has much room for improvement.
Summary of the invention
In view of this, live line work insulating rope it is an object of the invention to propose a kind of modification of aramid fiber, using this fiber to make and preparation method thereof, to improve its anti-moisture absorption energy and resistance to UV aging.
To this end, the technical scheme is that the preparation method of a kind of modification of aramid fiber, the step including following:
