Abstract
The invention belongs to electric wire and cable protection and electric insulating adhesive tapes, and particularly relates to liquid insulating glue for a cable joint. The liquid insulating glue contains modified rubber and non-polar solvent and also can contain oil-soluble resin and/or copper corrosion inhibitor, wherein the consumption of the modified rubber is 10 to 40 percent of the total mass; and a formed insulating protective layer has excellent insulating performance and properties of resisting moisture, water, oxidation and acid and alkali corrosion. The liquid insulating glue can be used for joint coating and insulation of a metal lead, and also can be used for repair of cable outer sheaths and waterproof seal of embedded electric wires and cables.
Description
Technical field
The invention belongs to electric wire protection class and electric insulation adhesive tape class, particularly relate to and a kind ofly be used for electric wire splice insulation protection and prevent oxidized, variable color or the corrosive chemical.
Background technology
In the various means of defence of electric wire joint, it is modal adopting insulation tape to tie up, and insulation tape is made up of base band and pressure-sensitive adhesive layer.Base band generally adopts cotton, synthetic fabrics, woven fiber glass, polyester and PVC plastics film etc., and glue-line is added Synergist S-421 95 such as tackifying resin to be made by rubber, and it is good to have viscosity, and insulating property are good, and difficult combustion is from the advantage of putting out.But tie up owing to adopt, the slit of both sides' binding site between the lead inevitably occurs.The consequence that cause in this slit is that air and corrosive liquid such as airborne corrosive gases and rainwater touch lead by the slit easily, causes the lead oxidation thus, loose contact, and the contact electricity resistive is big, faults such as conductor joint heating, the meeting that situation is serious causes fire.
That uses fluid insulation in electrical equipment industry has Resins, epoxy, silicone resin, modified phenolic resins, polyester and a urethane resin, and by above-mentioned thermosetting resin be the basis various chemical modification products, the dielectric adhesive of the mutual modification of epoxy---silicone---heterocyclic polymer particularly, have the advantage of various single polymers concurrently, in the electrothermal device insulation-encapsulated that thermotolerance is had relatively high expectations, have one's own knack, but these all can only be used for the relative fixed device, and having flexible electric wire can't use.
Summary of the invention
Defective at existing electric wire splice insulation sealing technique, it is base material that the present invention adopts flexible fabulous modified rubber, the employing non-polar solvent disperses, and only need adopt mode such as soak, be coated with that joint is covered fully during use, treats can realize seamless insulation after solvent volatilizees fully.
The technical scheme that technical solution problem of the present invention is taked is: a kind of fluid insulation glue that is used for cable splice, comprise modified rubber and non-polar solvent, and the consumption of described modified rubber is 10%～40% of a total mass; The insulating property of formed insulating protective layer are good and have a performance of protection against the tide, waterproof, anti-oxidation, acid-alkali-corrosive-resisting.
As a kind of preferred, the consumption of described modified rubber is 20%～30% of a total mass.
As a kind of improvement, it can also contain oil-soluble resin and/or copper inhibitor.
Described modified rubber is one or more the mixture in modified chloroprene rubber, modified styrene butadiene rubber, modified butyl rubber, the modification ethylene-propylene rubber(EPR).
Described non-polar solvent is one or more the mixture in benzene, toluene and the dimethylbenzene.
Described oil-soluble resin is one or more the mixture in rosin and derivative, dammar gum, soluble phenolic resin, coumarone-indene resin, petroleum resin and the terpine resin.
Described copper inhibitor is benzotriazole and derivative and/or benzoglyoxaline and derivative thereof.
The preparation of product of the present invention is very convenient, only needs in proportion modified rubber to be dissolved in the solvent, and stirring gets final product; Also can add an amount of oil-soluble resin and/or copper inhibitor.
The use of product of the present invention is very simple, only the hinged back of electric wire need be immersed wherein and be taken out then, perhaps product of the present invention is brushed on joint, notes not interspacing, and treats that forming elastic insulated glued membrane after solvent volatilizees fully gets final product.
Product of the present invention has following advantage: at first, solvent evaporates is fast, and it is good to form insulating protective layer (glued membrane promptly insulate) and insulating property at short notice; The second, the thickness of formed insulation glued membrane can be regulated as required; The 3rd, the insulation paste membrane closure of formation the joint of plain conductor, make the junction seamless, thoroughly secluding air, steam prevent corrosion; The 4th, be base material owing to adopt flexible fabulous modified rubber, the insulation glued membrane softness of formation, good percentage elongation, lead is arbitrarily bending and not coming unstuck still; The 5th, also can be used for the cable jacket reparation, and the waterproof sealing of buried electric wire or the like.
