Abstract
The utility model relates to a water-resistant yarn for a cable and an optical cable. In the process of manufacturing the cable and the optical cable, water-resistant material needs filling to solve the problems of longitudinal water resistance and water trees, and the utility model meets the requirements. The utility model is characterized in that the utility model is evenly attached with solution containing water-absorption resin having high magnification on a bundle of filament fiber; after other components in the solution are volatilized, only the water-absorption resin having high magnification is left on a bundle of filament fiber. The utility model is used for water resistance and damp insulation of the cable and the optical cable; accordingly, the safe operation of the cable and the optical cable is ensured, and the service life is extended.
Description
The utility model relates to a kind of material water-proof material, the water blocking yarn that particularly a kind of cable, optical cable are used.
Power cable is in operation, and the cable core electric current can produce powerful electric field, if there is moisture to infiltrate insulating barrier, forms water tree, and the fault location in the sheath will produce discharge, even punctures cable.
In communication cable, the mechanical pressure in covering or keeping in repair, defective in the insulating barrier and cable joint damage, and all can cause the infiltration of water, and especially in sheath, water will vertically be stretched along the cable axle, cause the signal noise of communication cable.Same problem is also arranged in the optical cable, thereby influence the signal transmission of optical cable, cause the scattering of light signal.
For addressing the above problem, guarantee the safe operation of cable, optical cable and increase the service life that adopt greasy for preventing water to solve usually, but its processing is loaded down with trivial details, waterproof effect is poor.Adopt waterstop afterwards, solved the problem of blocking water to a certain extent, but do not satisfy the requirement that vertically blocks water and fill the cable core gap.
Patent CN10735-46A discloses a kind of communication cable water blocking yarn, and it is formed through the sliver arrangement by water-absorption fiber and polyster fibre blending.But temperature tolerance is bad, and tensile strength is low, and vertically block-water effect is undesirable.
The purpose of this utility model is to provide a kind of material water-proof material, not only can vertically block water, and blind can also adapt to the high temperature production environment in the stranding manufacturing process.
The utility model is realized by following measure:
On the fiber filament bundle, evenly adhere to the solution that contains the high magnification water-absorbing resin, after the volatilization of other composition in the solution, have only above the high magnification water-absorbing resin stays.Wherein fiber filament Shu Bixu has high-tensile and temperature tolerance, can be polyester filament, vinylon long filament or polyvinyl chloride fibre long filament.The high magnification water-absorbing resin can be any one or its copolymer in polyacrylamide, polyacrylate, polyacrylate, the modified cellulose.
The utility model is compared with conventional art, have following advantage: expansion is rapid when meeting water, water absorbent rate is high, vertically block-water effect is good, and have good tensile strength and thermal stability, and not being subjected to Effect of Hyperthermic Environment, the high magnification water-absorbing resin combines with fiber filament firmly, not shedding in use, not bonding, production technology is simple, and technical performance is stable, and is practical.
The drawing of accompanying drawing is described as follows:
Accompanying drawing is the cross section structure figure that the utility model cable, optical cable are used water blocking yarn, and wherein 1 is fiber filament, and 2 for staying the high magnification water-absorbing resin on the fiber filament.
Embodiment:
Be immersed in the polyester filament of 2000D contain＜solution of 100 purpose polyacrylamide resins in, dried under 120 ℃ condition forms water blocking yarn.Water absorbent rate is 80 times, tensile strength＞50N.
