The electric stress relief adhesive for connecting thermal shrinkage cable accessories of the invention has good bonding intensity on aluminium, lead, copper and oil isolating pipe, has excellent bonding sealing, airtight, weatherability and aging resistance in an insulating cable joint, and has proper dielectric constant and volume resistivity, large tensile strength and good effect on mitigating and dispersing electric stress.
Description
Technical field
The present invention relates to a kind of electric stress and evacuate glue, relate in particular to a kind of electric stress evacuation glue that the pyrocondensation cable accessory connects that is used for.
Background technology
Power cable line is the important component part of railway power system, and power cable terminal is the vitals in the cable line, also is the weak link of cable road reliability service, and about 70% of cable fault all occurs on the cable terminal end.It is initial that what use is housing filling type cable terminal end, but there is that volume is big, inconvenient installation, metal consumption is big, cost is high characteristics.To above shortcoming, developed the thermal shrinkage type cable terminal end eighties in 20th century, widely-used in the railway power supply system; Advantage is applied widely, makes simply, and volume is little; In light weight, but the temperature of have heat shrink simultaneously time heat is wayward, it is proper that the interface of cable terminal end and stress disperse to be difficult for processing; Because of need are used naked light, install dangerous in inflammable and explosive place.Particularly through more than ten years operation practice, though the terminal fault of thermal shrinkage type cable terminal end much smaller than filling type and dried packet mode cable terminal end, but because above-mentioned shortcoming, fault can not be ignored in recent years.
In recent years, a large amount of pyrocondensation cable accessories that use in transmission of electricity industry and other industry are both at home and abroad constructed with joint for cable terminal end and to be brought great convenience.Partly lead self-adhesive tape and 12 stress tubes but the mounting process of in application, finding the middle connection of thermal contraction cable uses, technology is loaded down with trivial details.Therefore can develop the reelable a kind of novel filling glue that can control electric field distortion, promptly electric stress is evacuated glue, replaces partly leading self-adhesive tape and stress tube with it.
Summary of the invention
In order to solve the above-mentioned deficiency that prior art exists; Technical problem to be solved by this invention provides a kind of electric stress evacuation glue that the pyrocondensation cable accessory connects that is used for; Have suitable specific inductivity and volume specific resistance, tensile strength is bigger, disperses electric stress to have good effect to relaxing.
The objective of the invention is to realize like this:
A kind of electric stress that is used for the connection of pyrocondensation cable accessory is evacuated glue, is made up of by weight following component: elastomerics 20-50 part, tackifier 20-50 part, conductive filler material 15-50 part, oxidation inhibitor 0.5-5 part, fire retardant 2-5 part, lubricant 0.5-1 part.
Preferably,
Said elastomerics is a kind of or its mixture in styrene-butadiene rubber(SBR), paracril, butyl rubber, chlorohydrin rubber and the urethanes.The elastomerics that the present invention adopted is a thermo-setting elastomer, has good tensile and consistency.
Said tackifier are a kind of or its mixture in terpine resin, ester gum, petroleum resin and the polyisobutene.The tackifier that the present invention adopted can improve the flowability and the consistency of whole system.
Said conductive filler material is a kind of or its mixture in graphite, Shawinigan black, barium titanate, conductive mica powder, conductive titanium dioxide and the silver-coated copper powder.Can guarantee that electric stress evacuation glue has good specific inductivity and volume specific resistance.
Oxidation inhibitor according to the invention is polynary hindered phenol type antioxidant, further is preferably four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester, the common name antioxidant 1010.
Said lubricant is a stearate, like barium stearate, and Zinic stearas etc.
Said fire retardant is a kind of or its mixture in white lake, Marinco H, Antimony Trioxide: 99.5Min, the decabromodiphynly oxide.
Adopt industry ordinary method, each component through the back extrusion moulding in rubber extruding machine that in kneader, stirs fully, is processed strip, can make the electric stress evacuation glue that the pyrocondensation cable accessory connects that is used for of the present invention.
During use; The electric stress that is used for the connection of pyrocondensation cable accessory of the present invention is evacuated glue be wound in power cable terminal and joint construction, can obtain great convenience, have suitable specific inductivity and volume specific resistance; Tensile strength is bigger, disperses electric stress to have good effect to relaxing.
With respect to prior art, beneficial effect of the present invention is embodied as:
1. the present invention is used for electric stress that the pyrocondensation cable accessory connects and evacuates glue aluminium, lead, copper and oil removal pipe and insulation tube are all had cohesive strength preferably, in the insulated cable joint, has good being bonded and sealed property, resistance to air loss, weathering resistance, stability to aging.
2. the present invention is used for electric stress that the pyrocondensation cable accessory connects and evacuates glue and can alleviate electric field stress and concentrate, and improves insulation shield layer cut-off part and gets electric stress and distribute; Hardness (Shao Shi A) is 38-50, the about 5MPa of tensile strength.
3. the present invention is used for electric stress that the pyrocondensation cable accessory connects to evacuate the specific inductivity (1khz) of glue is 15-30, and volume specific resistance is about 1.0 * 10
11-1.0 * 10
13, avoid equipment in long-time running, the temperature that shelf depreciation causes raises, insulating material is aging.
4. the present invention is used for electric stress that the pyrocondensation cable accessory connects to evacuate glue is main with mold pressing, extrude produce easy to use.
