Description
Technical field
The present invention relates to a kind of repairing adhesive tape, a kind of cable is with repairing adhesive tape and preparation method thereof.
Background technology
Finding in distribution overhauls, the basic reason that cable breaks down is that insulating properties reduces and the breakdown that causes is broken
Bad, and the main cause causing cable covering insulating properties to reduce is more, such as: cable is excessive curved during construction is laid
Bent, the wound of external force is hit or the local excessive caused that rubs stretches and ruptures and causes, and the hidden danger of this kind of mechanicalness damage is relatively big, and first
Phase is easy to be left in the basket；Secondly as the self deterioration of material, corrosion etc. caused by the character of the environment in the external world and material itself；
Furthermore, cable is in operation and also can be frequently encountered by various overvoltage, to such an extent as to the fault occurrence frequency of power cable is relative to it
It is that comparison is many for its electrical equipment.No matter in life or producing, cable fault all has the biggest harm, the most then lead
Cause to have a power failure and stop production, heavy then cause electric shock to cause casualties, even can also cause fire, consequence is the most serious.Therefore, periodically
Power cable is carried out Insulation Test, finds the operation hidden danger of power cable early and eliminated and be to ensure that power cable safety
The important measures running, preventing cable fault from occurring.
At present, the method repairing cable has a hot repair, cable cold repair glue and repair adhesive tape etc., wherein, repair adhesive tape by
In easy to use, simple to operate, safety is higher and can tackle general sudden cable fault, so being widely used.
But, the performance repairing adhesive tape also needs to further improve, such as: owing to the voltage of cable is higher, to repair sheets tape insulation
Have higher requirement, existing repairing adhesive tape, the generation of the secondary cable accident caused due to insulating properties deficiency is more, and
Endanger the biggest；Owing to repairing adhesive tape in use, need the pretension certain to material, and prolongation over time, adhesive tape
Pretension can gradually weaken, the cementing strength of cable adhesive tape also can gradually disappear, and ultimately results in coming off of cable adhesive tape；
The intensity of adhesive tape is relatively low, becomes the weak link of cable；The winding of adhesive tape adds the thickness of cable covering, dispels the heat and conducts heat
Effect reduce, accelerate the aging of cable adhesive tape.
On the basis of existing technology, applicant, through improvement repeatedly and experiment, finally solves this technological deficiency, carries
Gone out a kind of new technical scheme, and provide a kind of intensity height, good toughness, insulating properties strong and have preferable cementing strength and
The cable repairing adhesive tape of radiating effect.
Summary of the invention
The technical problem to be solved is to provide a kind of cable and repairs adhesive tape and preparation method thereof.
For solving above-mentioned technical problem, technical scheme solves the most from the following aspect: (1) is by adding polyoxy
Change ethylene polyhydric alcohol and dipropylene glycol and improve o-toluene diisocyanate and the gumminess of p-phenylene diisocyanate: polyoxyethylene
Alkene polyhydric alcohol and dipropylene glycol with the use of, it is possible to play synergism, and o-toluene diisocyanate and p-benzene two Carbimide.
Ester with the use of can be complementary, and by screening the molecular weight of polyoxyethylated polyols, coordinating other material performances
On the basis of, gumminess is improved further, and has played the decay resistance of material itself.(2) send out in experimentation
Existing, there is certain contradiction between insulating properties and the heat conduction and heat radiation performance of material, as, although the heat conductivility of material is along with metal
The increase of oxide and strengthen, but too much metal-oxide can reduce the insulating properties of material, and the heat conduction and heat radiation of material
Other performances of material can be affected the most again.This programme by strict control carborundum and the proportioning of alchlor and
Usage amount reaches the balance of material conducts heat and insulation.(3) relatively big due to the flexibility of material, and heat distortion temperature is relatively low,
Then affect intensity and the toughness of material, and by adding carbon fiber and alchlor, improve intensity and the toughness of material, with
Time alchlor can work in coordination with carborundum and optimize the heat conductivility of material further；By adding stannous octoate and Sanya in this programme
Ethyldiamine, under identical testing conditions, cementing intensity increases significantly, and when the proportioning of the two is in certain limit
The most more can play the bonding capacity of material, and the speed of solidification the most significantly improves.(4) by adding the polyether-ether-ketone material of resistance to raising
High temperature resistant and the electrical insulation capability of material, and polyether-ether-ketone can with carbon fiber with the use of, the common intensity improving material and toughness,
Serve beyond thought effect.(5) in order to reach the target of design, it is inadequate by assembling of raw material, each raw material
Select to affect the most to a certain extent the overall performance of material, make a formal request people through selecting materials and allocating repeatedly, finally determine
Technical scheme, to reach the balance between design requirement and material property.
Applicant, by experiment repeatedly, has finally made following technical scheme, described a kind of cable repair sheets

Slowly add serosity A, pour in agitator after reacting 6-7 hour, and by methyl-silicone oil, stannous octoate, triethylenediamine,
Polyether-ether-ketone, dibutyl ester are sequentially added into agitator；
(4) remaining raw material is added in step (3), and add remaining butanone, with 70 rpms under conditions of rushing nitrogen
Rotating speed stir and be cooled to room temperature and obtain serosity B；
(5) the serosity B that step (4) obtains is spread upon in fiber cloth uniformly, then pack under conditions of rushing nitrogen, seal up for safekeeping.
