Abstract
The invention discloses a water-blocking tape of a moistureproof electricity cable, comprising water-blocking materials and non-woven cloth; both sides of the water-blocking tape are connected with the non-woven cloth through a bonding agent; the water-blocking materials comprise high-magnification water absorbing resin and surface moisture absorption resisting material; the surface moisture absorption resisting material is uniformly distributed on the surface of the high-magnification water absorbing resin, and a layer of drying agent is coated on the non-woven cloth. Through the method, the moistureproof performance can be improved and the service life can be prolonged.
Description
Technical field
The present invention relates to the plastic product design field, particularly relate to a kind of moistureproof power cable waterstop.
Background technology
Power cable is requisite transmission of electricity instrument in the power circuits such as Urban Underground electrical network, power station, waterstop is the part of power cable, common waterstop moisture absorption is stronger, one runs into aqueous vapor will expand rapidly, thereby forfeiture block-water performance, shorten like this useful life of power cable, therefore can not satisfy the demand of electric power transfer.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of moistureproof power cable waterstop, can improve humidity resistance, increases the service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of moistureproof power cable waterstop is provided, comprise material water-proof material and nonwoven fabrics, described material water-proof material both sides all are connected by adhesive with nonwoven fabrics, described material water-proof material comprises high magnification water-absorbing resin and surperficial anti-hygroscopic material, the anti-hygroscopic material in surface is evenly distributed on high magnification water-absorbing resin surface, scribbles one deck drier on the described nonwoven fabrics.
In a preferred embodiment of the present invention, described drier is the calcium chloride powder.
In a preferred embodiment of the present invention, the anti-hygroscopic material in described surface is comprised of organosilicon, cyclohexane, sapn.
The invention has the beneficial effects as follows: can improve humidity resistance, increase the service life.
Description of drawings
Fig. 1 is the structural representation of moistureproof power cable waterstop one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, material water-proof material; 2, nonwoven fabrics; 3, adhesive.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of moistureproof power cable waterstop, comprise material water-proof material 1 and nonwoven fabrics 2, described material water-proof material 1 both sides all are connected by adhesive 3 with nonwoven fabrics 2, described material water-proof material 1 comprises high magnification water-absorbing resin and surperficial anti-hygroscopic material, the anti-hygroscopic material in surface is evenly distributed on high magnification water-absorbing resin surface, scribbles one deck drier on the described nonwoven fabrics 2.
Wherein, described drier is the calcium chloride powder, and the anti-hygroscopic material in described surface is comprised of organosilicon, cyclohexane, sapn.
In wet weather, when aqueous vapor entered optical cable, the drier on the nonwoven fabrics can absorb aqueous vapor, simultaneously, the anti-hygroscopic material in surface can form thin film on high magnification water-absorbing resin surface, can prevent that like this high magnification water-absorbing resin from expanding and the useful life of shortening waterstop.When power cable was switched on, the core in the power cable was because there being internal resistance to produce heat, and when weather was better, the heat that drier can absorb in the air and core sheds evaporated away the moisture in the drier.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
