Abstract
The utility model relates to a water-blocking and flame-retardant belt used for cables and optical cables, which comprises a basal material layer, a flame-retardant material layer and a high-magnification water-absorbing material layer or comprises the basal material layer, the flame-retardant material layer, the high-magnification water-absorbing material layer and a covering layer, wherein the flame-retardant material layer can be attached to one surface or both surfaces of the basal material layer, the high-magnification water-absorbing material layer can be attached to one surface of the basal material layer or be attached to one surface or both surfaces of the flame-retardant material layer, and the covering layer can be attached to one surface or both surfaces of the high-magnification water-absorbing material layer. The water-blocking and flame-retardant belt used for the cables and the optical cables is applicable to the laying of the cables and the optical cables and the requirements for the use environment thereof and has double effects of blocking water and retarding flames.
Description
Technical field
The utility model relates to a kind of fire proofing that blocks water, and particularly relates to a kind of cable, optical cable with the inhibiting tape that blocks water.
Background technology
Because humid environment, the moisture content of cable material itself, and the result of effect of stress, chemistry, power cable is in operation, the capital forms " water tree " phenomenon, cause insulating barrier to destroy, the fault location in the sheath will produce discharge, even punctures cable, cause the loss of power accident, and same problem is also arranged in the optical cable, thus influence the signal transmission of optical cable, cause communication quality to reduce.
For addressing the above problem, adopt waterstop at present usually, but under special circumstances, cable, optical cable also require to have fire resistance, to solve security against fire hidden danger with block-water performance.The waterstop, the inhibiting tape that use in cable, cable configuration at present block water and fire resistance though have, normally two kinds of structures that material repeatedly holds, two kinds of material properties interact, reduced fire-retardant and block-water performance, and the production cost height, be difficult to popularize.
Summary of the invention
The inhibiting tape that blocks water that provides a kind of cable, optical cable to use is provided the purpose of this utility model.The inhibiting tape that blocks water is a multi-layer compound structure, can not only satisfy the requirement of filling the cable core gap, and can be suitable for the requirement of laying cable, optical cable and environment for use thereof again, has to block water and fire-retardant double effects.
The purpose of this utility model is achieved through the following technical solutions:
Cable, optical cable are made up of substrate layer, fire proofing layer and high magnification absorbent material layer with the inhibiting tape that blocks water, and also can be made up of substrate layer, fire proofing layer, high magnification absorbent material layer and cover layer.Described fire proofing layer is attached on surface of substrate layer or two surfaces; Described high magnification absorbent material layer is attached on the surface or two surfaces of surface of substrate layer or fire proofing layer.The high magnification absorbent material layer can combine with substrate layer or fire proofing layer by bonding, coating, the multiple mode of impregnating.
Fire-retardant dank material cover layer can be attached on the surface or two surfaces of high magnification absorbent material layer.Cover layer can combine with the high magnification absorbent material layer by multiple modes such as bonding, coatings.
Advantage of the present utility model and effect are:
Product water absorbent rate height of the present utility model is met water and is expanded rapidly, fills the cable core gap, and block-water effect is good, the flame retardant effect ideal.And not shedding in use, adhesion.Production technology is simple, and technical performance is stable, and is practical.
