Abstract
An insulation sealing method of a cable joint is disclosed. Natural rubber particles and channel black are uniformly stirred. And then zinc oxide, sulphur, stearic acid, an accelerant DM and an accelerant TMTD are successively added and are stirred uniformly. Finally, liquid polyisobutene, a rubber antioxidant RD, rosin and alpha-pinene resin are successively added and are stirred uniformly. The above mixture is heated to 100 DEG C and thermal insulation is performed, and then the mixture is cooled to a room temperature so as to acquire waterproof insulation rubber mud. The waterproof insulation rubber mud is pressed into a sealing waterproof insulation rubber mud strip. Two cable joints of a cable to be connected are connected and then the sealing waterproof insulation rubber mud strip is used to fill in a gap between the two connected cable joints. And then the sealing waterproof insulation rubber mud strip wraps a connection position of the two cable joints and finally an electric adhesive plaster is used to carry out fixation. The method has advantages that operation is convenient and fast; effects of isolating air and moisture and insulating are possessed; the cable joint which is bared in the air or in the ground is protected; and conditions of oxidation and electric leakage of a line contact point and a large contact resistance can be avoided.
Description
Technical field
The present invention relates to a kind of insulated enclosure method of cable connector.
Background technology
In cable installment work or cable fault repairing in, underground electric line joint often occurs, typically use distribution box,
Buried cable well or be wound around the mode of mackintosh outside cable and carry out cable insulation.Wherein, being wound around mackintosh outside cable is one
Plant and relatively facilitate quick way, but, out of doors in wet environment, underground aquifer, water or in adverse circumstances, the most not
The insulating properties of cable can be ensured, easily produce oxidation, leaky occur, affects line security, or cause contact resistance mistake
Greatly, cable service life is affected.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of insulated enclosure method of cable connector, convenient to operation, has
Air-isolation, isolation moisture and the effect of insulation, protect exposed at air or the cable connector of underground, to avoid line contacts oxygen
Change is leaked electricity, contact resistance is excessive, is suitable for applying in outdoor wet environment, underground aquifer, water or in adverse circumstances.
The technical solution of the present invention is:
A kind of insulated enclosure method of cable connector, it specifically comprises the following steps that
1.1, preparation seals waterproof insulation rubber cement
By 100g natural rubber granule and 58g～60g channel black uniform stirring, sequentially add 6g～6.5g zinc oxide, 3g～3.5g
Sulfur, 3.5g～4g stearic acid, 0.4g～0.6g altax and 1.3g～1.5g Vulcanization accelerator TMTD stir, finally
It is sequentially added into liquid polyisobutylene 32g, 0.8g～1g rubber antiager RD, 10g～10.5g Colophonium and 12g α pinene resin to stir
Mix uniformly, be then heated to 100 DEG C and keep 40min～60min, be cooled to room temperature, prepare waterproof insulation rubber cement, sealed bundle
Dress；
1.2, preparation seals waterproof insulation rubber cement bar
Waterproof insulation rubber cement is pressed into thickness be 1.5mm～3mm, width be the sealing waterproof insulation rubber cement bar of 3cm～5cm,
To seal waterproof insulation rubber cement bar upper surface and have one layer of antiseize membrane, lower surface has one layer of anti-paper, rolls into web-like, standby
With；
1.3, cable surface processes
After removing the oil of cable connector junction, dirt and dust, dry；
1.4, cable connector insulated enclosure
After being connected by two cable connectors of cable to be connected, the sealing waterproof insulation rubber cement bar taking step 1.2 preparation is rubbed,
Or directly take the waterproof insulation rubber cement of step 1.1 preparation, fill in gap between two cable connectors after connecting waterproof absolutely
Edge rubber cement, is then coated with the sealing waterproof insulation rubber cement bar of one layer of step 1.2 preparation, uses two cable connector junctions
The sealing waterproof insulation rubber cement bar of hands spreading cladding, makes sealing waterproof insulation rubber cement connect the most bonding with power circuit, then
Article two, cable connector junction is coated with the sealing waterproof insulation rubber cement bar of 1 layer～3 layers step 1.2 preparation, by hands spreading cladding
Seal waterproof insulation rubber cement bar, make sealing waterproof insulation rubber cement bar bonding firmly, then use electric power immobilization with adhesive tape.
Zinc oxide, the vulcanizing activator of rubber cement synthesis and reinforcing agent, sulfuration can be promoted, improve rubber cement crosslink density,
Tack of materials be can preferably improve, adhesive force and the ageing-resistant performance of rubber cement improved.
Sulfur, in rubber cement building-up process, and forms disulfide bond, makes rubber molecule structure more between the rubber molecule of chain
Add stable.
Stearic acid, rubber cement synthesis vulcanizing activator, plasticizer and softening agent, stearic acid and zinc oxide compound use have association
Same-action, plays excellent sulfuration promotion and activation.
Rubber accelerator DM, chemical name: 2,2'-dithio-bis-benzothiazole, rubber cement synthesis accelerant, in sizing material
Easily disperse, do not pollute, in the presence of active dose of zinc oxide with stearic acid, when vulcanizing together with sulfur, decomposite
Double-basis active sulfur or many bases active sulfur, can make rubber molecule cross-link.
Vulcanization accelerator TMTD, rubber cement synthesis delayed action accelerator, it is used in combination with zinc oxide, the sulfuration with excellence promotes
Effect.
Channel black, rubber cement synthesis reinforcing agent, hot strength and the percentage elongation of rubber cement can be increased, anti tear and anti-cut
Cut performance.
Liquid polyisobutylene, has permanent adhesive, the fabulous compatibility and resistance to ag(e)ing, can increase the low tenderness of rubber cement
Soft and tack, extends storage period.
Rubber antiager RD, belongs to ketone amines antioxidants, and the protection to thermo-oxidative ageing is highly effective, the catalysis oxygen to metal
Change and also have extremely strong inhibitory action.
Colophonium, rubber cement softening agent, rubber cement can be increased elastic.
α pinene resin, has preferable heat stability and electrical insulating property.
Beneficial effects of the present invention:
Cable connector has insulation and water resistance after sealing, be suitable for using under outdoor operating mode.Seal waterproof insulation rubber cement to not advising
Then surface has good from shape, good with the various cable compatibilitys, has copper, aluminum and cable sheath material splendid bonding
Performance, uses wide-40 DEG C～+40 DEG C of temperature range, easy to use, it is not necessary to heat or pressurize, and forms zero-clearance and insulate uniformly,
Clay is removed easily, without cull, will not be hardening, and tear-resistant, water resistance good, low-down water absorption rate；Can effectively seal also
Insulation processing power circuit contact, has air-isolation, isolation moisture and the effect of insulation, protects exposed in air or underground
Line contacts, is prevented effectively from line contacts oxidation electric leakage, contact resistance excessive, it is ensured that power circuit service life, and very well
Reach insulation effect.
