Abstract
The invention relates to a waterproof adhesive tape for a cable and a preparation method of the waterproof adhesive tape. The waterproof adhesive tape comprises an inner layer and an outer layer, wherein the inner layer is a waterproof layer; the outer layer is a reinforced rib layer; the reinforced rib layer is arranged on the waterproof layer in a thermal binding manner. The adhesive tape provided by the invention adopts a double-layer structure; due to the adoption of the reinforced rib layer, the stretchability of the adhesive tape is effectively improved; due to the adoption of the waterproof layer, adhesive tapes can be combined and dissolved with each other, so that a sealed integral part is formed after a part to be sealed is winded by the sealing waterproof adhesive tapes, and the material used in the waterproof adhesive tape can be used at the temperature of minus 10 DEG C to 200 DEG C.
Description
Technical field
The invention belongs to cable protective tool field, especially a kind of adhesive waterproof tape for cable and preparation method thereof.
Background technology
Along with the widespread use of novel process cold contract cable middle joint, expose gradually the weakness of its water resistance through long-time running, be exactly that cable can inevitably receive that in laid processes damage causes oversheath water inlet in addition, especially the city of underground water high-water, the result of cable water inlet is exactly the Frequent Troubles that causes cable.
At present, cable intermediate joint and or cable jacket breakage all by adhesive tape pastes winding fixed and waterproof, but after life-time service, there is obvious breakage, mainly cause because adhesive tape cohesive force declines and adhesive tape is aging, simultaneously because adhesive tape under some environment is corroded, also cause breakage, thereby had a strong impact on its water resistance.
Through retrieval, do not find the patent documentation relevant to this patent content.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of stable performance and adhesive waterproof tape that can be effectively crosslinked at cable intermediate joint or cable jacket place and preparation method thereof are provided.
The present invention solves its technical problem and takes following technical scheme to realize:
For an adhesive waterproof tape for cable, comprise internal layer and skin, internal layer is waterproof layer, and skin is stiffening web layer, and stiffening web layer is heat sealing on waterproof layer, and wherein the feed composition of waterproof layer and proportioning are:
And described stiffening web layer is to be worked out according to rhombus reticulate pattern by high-strength glass fibre 60%, nylon fiber silk 10%, polypropylene filaments 30% ratio.
And it is banded that described stiffening web layer entirety is.
The preparation method of above-mentioned adhesive waterproof tape is:
That polyvinyl alcohol is dissolved in tetraline at 100~150 DEG C, treat that it is cooled to 60 DEG C, successively add pentyl acetate, industrial carboxymethyl cellulose, ethylene-propylene rubber(EPR), industrial sodium hydroxide, PSI, silica gel to carry out fully merging and form high viscosity colloid, it is squeezed in to pressurization on strong muscle layer through machine under constant temperature thickness is reduced to the laggard row air cooling of 0.5cm to normal temperature, be processed into adhesive tape or adhesive waterproof tape is further cooling after be rolled into volume, cut into goods according to dimension size.
Advantage of the present invention and positively effect are:
1, adhesive tape provided by the invention comprises waterproof layer and stiffening web layer; wherein waterproof layer and cable jacket or cable splice need waterproof sealing place outer jacket to dissolve each other; and stiffening web layer is the belt body that is woven into according to a certain percentage respective width by high strength fibre silk; Main Function is to coordinate with water-tight part; carry out water-tight; prevent that long-time rear water-tight colloid constrictive force is inadequate; strengthen water-tight, play fixing seal position simultaneously and prevent that external force from scratching the provide protection at sealing position.
2, adhesive tape provided by the invention has adopted bilayer structure, stiffening web layer has effectively improved the stretchiness that adhesive tape has, and waterproof layer makes between adhesive tape and adhesive tape interconnectedly to dissolve each other, make water-tight adhesive tape after need sealing position is wound around, form the entirety of a sealing, select materials performance is satisfied with-10 DEG C~200 DEG C.
3,, in the present invention, because cable jacket is to be mainly made up of polyethylene or pvc material, after being wound around in the above, reheat to 100 DEG C and will fusion occur again by [C

Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
For an adhesive waterproof tape for cable, comprise internal layer and skin, internal layer is waterproof layer, and skin is stiffening web layer, and stiffening web layer is heat sealing on waterproof layer, and wherein the feed composition of waterproof layer and proportioning are:
It is banded that stiffening web layer is, and is to be worked out according to rhombus reticulate pattern by high-strength glass fibre 6Kg, nylon fiber silk 1Kg, polypropylene filaments 3Kg ratio.
The preparation method of above-mentioned adhesive waterproof tape is:
That polyvinyl alcohol is dissolved in tetraline at 100~150 DEG C, treat that it is cooled to 60 DEG C, successively add pentyl acetate, industrial carboxymethyl cellulose, ethylene-propylene rubber(EPR), industrial sodium hydroxide, PSI, silica gel to carry out fully merging and form high viscosity colloid, it is squeezed in to pressurization on stiffening web layer through machine under constant temperature thickness is reduced to the laggard row air cooling of 0.5cm to normal temperature, be processed into adhesive tape or adhesive waterproof tape is further cooling after be rolled into volume, cut into goods according to dimension size.
Cable need to clean after drying treatment in sealing place, and the present invention is firmly stretched and makes its width become 1/2 o'clock of former width, is wrapped in place to be sealed according to half overlap mode, be wound around back and forth two-layer, with spray gun or well heater with 100 DEG C of heating 1 minute.
In the present invention, cable sheath (inside and outside) is generally polyvinyl alcohol in 100 DEG C of high temperature and adhesive waterproof tape of polyethylene or polyvinyl chloride material, tetraline, PSI etc. and copolyreaction occurs forms an entirety.
100 DEG C of principal reaction molecular formula
Because cable jacket is to be mainly made up of polyethylene or pvc material, after being wound around in the above, reheat to 100 DEG C and will fusion occur again by [C
