Description
Technical field
The present invention relates on the shaft tower of transmission line, hang cap and pin insulator and bonding (fixing) synthetic full skirt thereon of a lead and an insulating effect by the manufacturing of macromolecular materials such as silicon rubber by porcelain or toughened glass manufacturing.Specifically, the present invention relates to bonded structure between suspension insulator and the synthetic full skirt.
Background technology
Silicon rubber is the anti-pollution flashover material of superior power external insulation, and the synthetic full skirt of silicon rubber manufacturing is bonded on the insulator, can bring into play the superiority of this material, also can increase the creepage distance of insulator, thereby improve the pollution flashover voltage of insulator significantly.It is that 90227039.7 patent is more early stage background technology file that on September 11st, 1991 bulletin, name are called " composite insulator ", application number.
The scheme of the synthetic full skirt of bonding silicon rubber has multiplely on porcelain or toughened glass individual layer umbrella plate shape suspension insulator, and wherein two kinds have the double-layer umbrella moulding after bonding finishing, comparatively approaching with the present invention.The ZL03204556.5 patent that on December 1st, 2004 bulletin, name are called " composite insulator " has been introduced in more detail has the superiority of double-layer umbrella moulding and concrete organization plan after bonding.
Scheme one is that synthetic full skirt is arranged on the waist of the chapeau de fer of existing insulator, and the interstitial hole that will synthesize full skirt extends the sticking reality of the upper surface of the end face of extension and insulator umbrella disk downwards with tubular.The shortcoming of this scheme is that the track walker can't see through the situation that silicon rubber removes to observe chapeau de fer, can not find the crackle that chapeau de fer occurs.
Scheme two is special cap and pin insulators that are suitable for bonding synthetic full skirt, the upper and lower surface of the umbrella disk of this insulator all is smooth, lower surface at its umbrella disk is provided with the bonding seat of the annular that stretches out downwards, the interstitial hole suit of synthetic full skirt is bonded on this bonding seat, and the moulding of the product of acquisition is identical with traditional double-deck umbrella plate shape suspension insulator.One of shortcoming of this scheme is that special insulator needs more development funds and time; Two of shortcoming is insulator and stock's insulators that this scheme can not be applied to move on electrical network, can not transform the insulator of the traditional design of these enormous amount; Three of shortcoming is that the creepage distance of the umbrella disk that has an even surface is shorter, and the length of umbrella rib is arranged not as the umbrella disk lower surface.
Summary of the invention
The new departure that the purpose of this invention is to provide the synthetic full skirt of on individual layer umbrella plate shape suspension insulator bonding silicon rubber both can obtain to have the insulator of double-layer umbrella moulding after bonding, can improve above-mentioned shortcoming again.
The feature of said individual layer umbrella plate shape suspension insulator is that the lower surface at its umbrella disk has a plurality of annular umbrella ribs that stretch out downwards.This insulator accounts for the overwhelming majority of hanging net operation and stock's the individual layer umbrella plate shape suspension insulator of being made by porcelain or toughened glass.The present invention will will synthesize the lower surface that full skirt is bonded in the umbrella disk of this insulator, and forms an independently newborn umbrella disk.(annotate: said herein " independently newborn umbrella disk " also can be called " independent umbrella disk ", be meant the second layer umbrella disk that is different from the original umbrella disk of individual layer umbrella plate shape suspension insulator, technical scheme on the other side is that the enlarged-diameter of original umbrella disk is not formed second layer umbrella disk, i.e. the scheme of No. 90227039.7 patents); (annotate: the individual layer umbrella plate shape suspension insulator that minority is special formed such as spherical or aerodynamic type, is not the object that relates to of the present invention).
(this specification with the lower part, the individual layer umbrella plate shape suspension insulator that sometimes this lower surface at its umbrella disk is had a plurality of annular umbrella ribs that stretch out downwards abbreviates " existing insulator " as.)
Make the field at operation of power networks and insulator, target of the present invention is that people thirst for the problem that solves always.The thinking that the long-term unsolved reason of this problem is people is subjected to the constraint of conventional insulators design bar frame.
One in these frames is: the minimum point of the umbrella disk of cap and pin insulator should be higher than the minimum point of steel pin.Its meaning is, in insulator string, umbrella disk should will not be positioned at latent the subtracting of locking pin parcel of the below of its steel pin, and should allow locking pin be exposed among the visual field and can touch easily, install and remove insulator string easily thereby help installing and removing easily locking pin, particularly live line working mounting or dismounting insulator string.(operation of power networks unit can use the insulator of breaking through this frame a little under the situation of having no alternative sometimes, because this can increase the work difficulty of live line working, hides the smaller the better so basic requirement remains umbrella disk to the parcel of locking pin).
When the technical staff who is subjected to this frame constraint considers at the synthetic full skirt of the lower surface bonds of the umbrella disk that has insulator, and when forming an independently newborn umbrella disk, he can think that the insulator of making can not be accepted by electrical network, and this is because the designer also must observe another designing requirement: minimum range between the umbrella of adjacent umbrella disk (notes: this speech is a scientific and technical terminology) should be greater than 30 millimeters.Thinking bound technical staff think very naturally, adding a umbrella disk beyond below the minimum point of the umbrella disk of existing insulator 30 millimeters again will wrap up locking pin dearly and stash, the live line working mounting or dismounting string performance of this insulator is very inferior, must be refused by electrical network.(annotate: following sometimes " the string performance is installed and removed in live line working " abbreviated as " mounting or dismounting string performance ").
One of contribution of the present invention is to prove that by experiment above-mentioned design bar frame about umbrella disk minimum point and steel pin minimum point relation is to use rigid materials such as porcelain or glass (material that modulus of elasticity is big) to make insulator and the technology prejudice that forms over more than 100 year always, it only is suitable for the insulator of rigid material, and when flexible (elasticity) materials such as using silicon rubber was made the insulator umbrella disk, this design bar frame can be broken through significantly.
This is a very simple experiment, and the suspension insulator of common size is fixing by user mode vertical (vertical), and by an end of 2.5 meters long wooden sticks of people's both hands gripping, two hold 0.55 meter of a distance, go to provoke the outer of insulator umbrella disk with the other end of wooden stick.If the insulator umbrella disk is made with porcelain or glass, this umbrella disk outer can be invisible by the displacement that wooden stick is provoked; If the insulator umbrella disk is made with silastic material, this umbrella disk outer can be not less than 40 millimeters to top offset by what wooden stick was provoked, and can intact recovery after removing the power of provoking.
This experiment shows, the synthetic full skirt of making by macromolecular materials such as silicon rubber in the lower surface bonds of the umbrella disk of existing insulator, and to form an independently newborn umbrella disk be feasible.Though it is hiding that newborn umbrella disk can wrap up locking pin dearly, its outer can upwards be provoked and be exposed locking pin, so the mounting or dismounting string performance of this insulator is not inferior, can live line working install and remove insulator string smoothly.
The present invention is the bonding suspension insulator of synthetic full skirt, and it contains organic insulating material, also contains inorganic insulating material, and therefore the present invention can be considered as is composite insulator.Concrete bonded structure of the present invention is, the interstitial hole of said synthetic full skirt extends upward with tubular, the a certain ring part phase-splitting of the lower surface of the umbrella disk of the top of this tubular extension and said suspension insulator (existing insulator) is bonding, and said " annular section " is a circumferentia round the closure of the steel pin of said suspension insulator.
(annotate: this specification with the lower part, sometimes " the tubular extension of the interstitial hole of synthetic full skirt " abbreviated as " tubular extension "; Sometimes " synthetic full skirt " speech comprises its tubular extension; Sometimes use " synthetic full skirt " speech to replace its tubular extension.)

Embodiment
In accompanying drawing 1, chapeau de fer 1, steel pin 2, umbrella disk 3 and encapsulated material 4 have been formed an individual layer umbrella plate shape suspension insulator (the 9th, the locking pin lock-joint) jointly.It is exumbrella rib 81 and interior umbrella rib 83 that the lower surface of the umbrella disk 3 of this suspension insulator has two annular umbrella ribs that stretch out downwards, also has an annular of stretching out to drip along 7 downwards.The structure height of this suspension insulator (annotate: this speech is a scientific and technical terminology) is 146 millimeters, and the diameter of umbrella disk 3 is 255 millimeters.The interstitial hole of synthetic full skirt 5 extends upward with tubular, and the lower surface of the top of this tubular extension and the umbrella disk of said suspension insulator 3 is by adhesive 6 bonding mutually (it is the part of lower surface of umbrella disk 3 that the present invention is considered as whole side surfaces of annular umbrella rib and lower surface).In addition, present embodiment is compared with the embodiment of accompanying drawing 3 and accompanying drawing 4 also has following feature: the interstitial hole of synthetic full skirt 5 extends upward with tubular earlier, shrink to the central horizontal of tube and extend, the part in umbrella rib 83 scopes of the lower surface of top of the outer surface of whole extension (comprising outer upper surface) and umbrella disk 3 is by adhesive 6 bonding mutually (said herein " parts in interior umbrella rib 83 scopes " comprise in the inner surface of umbrella rib 83).When having insulator by thinking transformation of the present invention, if conditions permit, should adopt the bonded structure of present embodiment as far as possible, this is because compare with 4 embodiment with accompanying drawing 3, the dynamo-electric intensity of this structure bonding plane is big, and the creepage distance that newborn umbrella disk increases for existing insulator is big.Adopt the synthetic full skirt finished product of high-temperature silicon disulfide rubber manufacturing, adopting the silicone rubber kinds adhesive to carry out bonding present embodiment then is most preferred embodiment of the present invention.
More than narration is introduced by a bonding synthetic full skirt of existing insulator, and this is in order to narrate conveniently.By technical thought of the present invention, it also is feasible that the existing insulator of some kind is installed additional a plurality of synthetic full skirts.Below introduce the embodiment that an existing insulator installs two synthetic full skirts additional.
In accompanying drawing 2, chapeau de fer 1, steel pin 2, umbrella disk 3 and encapsulated material 4 have been formed an individual layer umbrella plate shape suspension insulator (the 9th, the locking pin lock-joint) jointly.It is exumbrella rib 81 and interior umbrella rib 83 that the lower surface of the umbrella disk 3 of this suspension insulator has two annular umbrella ribs, also has an annular to drip along 7.The same model of the suspension insulator of this suspension insulator and accompanying drawing 1.Present embodiment is provided with two synthetic full skirts 5, and their interstitial hole is integrated when extending upward with tubular.The interstitial hole of two synthetic full skirts 5 extends upward with tubular earlier, shrinks to the central horizontal of tube and extends, and the top of the outer surface of whole extension is mutually bonding by adhesive 6 with the lower surface of umbrella disk 3, and concrete bonding position is identical with the embodiment of accompanying drawing 1.The insulator that makes has three layers of umbrella disk, though its minimum point still can be installed and removed string smoothly than also low about 25 millimeters of steel soles.Two synthetic full skirts 5 among Fig. 2 are made into one, also can make bonding being integral of recycle silicon rubber-like adhesive during enforcement respectively.Also can will be between the umbrella of two synthetic full skirts 5 among Fig. 2 during enforcement distance suitably strengthen, and between the umbrella of two synthetic full skirts 5, increase the synthetic full skirt of one deck (its diameter should be little, thickness should approach) again.
In accompanying drawing 3, chapeau de fer 1, steel pin 2, umbrella disk 3 and encapsulated material 4 have been formed an individual layer umbrella plate shape suspension insulator (the 9th, the locking pin lock-joint) jointly.It is exumbrella rib 81, middle umbrella rib 82 and interior umbrella rib 83 that the lower surface of the umbrella disk 3 of this suspension insulator has three annular umbrella ribs that stretch out downwards, also has an annular of stretching out to drip along 7 downwards.The structure height of this suspension insulator is 146 millimeters, and the diameter of umbrella disk 3 is 320 millimeters.The interstitial hole of synthetic full skirt 5 extends upward with tubular, and the top of this tubular extension is mutually bonding by adhesive 6 with the lower surface of umbrella disk 3.The bonded structure feature of present embodiment is that in the ring-shaped groove during the top of tubular extension extend between umbrella rib 82 and the interior umbrella rib 83, this groove is filled by adhesive 6 fully, to obtain good adhesive effect.It is that the top of tubular extension is not only mutually bonding with the inner surface of middle umbrella rib 82 but also mutually bonding with the outer surface of interior umbrella rib 83 that this bonded structure also can be considered, and just the gap of bonding plane is than broad (be that glue-line is thicker, the consumption of adhesive 6 is more).The implementer also can be with the top of tubular extension only mutually bonding with the outer surface of interior umbrella rib 83 (or only mutually bonding with the inner surface of middle umbrella rib 82), and the gap of bonding plane is changed narrow, to save the adhesive consumption.The implementer also can increase the quantity of the synthetic full skirt of present embodiment with reference to Fig. 2.
In accompanying drawing 4, chapeau de fer 1, steel pin 2, umbrella disk 3 and encapsulated material 4 have been formed an individual layer umbrella plate shape suspension insulator (the 9th, the locking pin lock-joint) jointly.It is exumbrella rib 81 and interior umbrella rib 83 that the lower surface of the umbrella disk 3 of this suspension insulator has two annular umbrella ribs that stretch out downwards, also has an annular of stretching out to drip along 7 downwards.The structure height of this suspension insulator is 146 millimeters, and the diameter of umbrella disk 3 is 280 millimeters.In industry, the diagram insulator is called bell-jar or dark umbrella rib formula insulator, and its umbrella rib is relatively more flourishing, have long creepage distance and protection creepage distance, but its umbrella disk minimum point is lower than steel pin minimum point, and therefore mounting or dismounting string performance is not good.Operation of power networks unit only uses this insulator in mist contaminated area, the ocean of especially severe.When this insulator being transformed, should must not note and make its not good enough further deterioration of mounting or dismounting string performance by thinking of the present invention.Therefore the synthetic full skirt 5 of present embodiment is shorter and smaller, and thinner thickness.The interstitial hole of synthetic full skirt 5 extends upward with tubular, and the lower surface of the top of this tubular extension and the umbrella disk of said suspension insulator 3 is bonding mutually by adhesive 6.The concrete bonded structure feature of present embodiment is that the top cover of tubular extension installs to the outside of exumbrella rib 81 and carries out bonding with this outer surface.In order fully to provoke with the outer that external force will be synthesized full skirt 5,6 of adhesive are filled into the middle part and the top of the outer surface of exumbrella rib 81, and reserving the bottom will not be bonding.When specifically implementing present embodiment, can suitably strengthen the umbrella disk diameter of synthetic full skirt 5, to improve correctional effect, insulator transports and the difficulty of lifting construction but this can increase.
Implement when of the present invention concrete, the implementer can intert the feature of above each scheme of combination.Such as, in accompanying drawing 4 schemes, the top of the tubular extension of the interstitial hole of synthetic full skirt 5 cover installs to the outside of exumbrella rib 81 and mutually bonding with this outer surface.The implementer can use this feature on the existing insulator of accompanying drawing 1, the outside of umbrella rib 83 and carry out bonding with this outer surface in the top cover of tubular extension that the bonded structure of accompanying drawing 1 is changed into the interstitial hole of synthetic full skirt 5 installs to.The another kind of method of interting combination is that the feature with accompanying drawing 3 uses on the existing insulator of accompanying drawing 1: (steel pin 2 was in hollow with the hollow Rotary-table before this for the tubular extension of the interstitial hole of the synthetic full skirt 5 of accompanying drawing 3, extend upward down together), after change into the hollow cylinder and extending upward, promptly, the projection line of this tubular extension on cutaway view extends obliquely upward with straight line earlier, when maintaining an equal level, change into so that straight line is vertical and extending upward with the lower edge of interior umbrella rib 83.The implementer can change the tubular extension of accompanying drawing 1 this shape making by accompanying drawing 3, promptly, projection line on cutaway view becomes, extend obliquely upward with straight line earlier, when maintaining an equal level to lower edge with interior umbrella rib 83, change into straight line vertical (or approximate vertical) and extending upward, turn again to the central horizontal of tube during near the lower surface of umbrella disk 3 and extend.Another program that the feature of accompanying drawing 3 is used accompanying drawing 1 is that the top with the tubular extension of the interstitial hole of synthetic full skirt 5 extend in the exumbrella rib 81 and the ring-shaped groove between the interior umbrella rib 83 of accompanying drawing 1, and with the surface adhesion (sticking with glue the agent filling groove) of this groove; The top that also bonded structure of accompanying drawing 1 can be changed into the tubular extension of the interstitial hole that synthesizes full skirt 5 extend into inboard and mutually bonding with this inner surface (identical with the former scheme of accompanying drawing 1, as to shrink the extension but cancel to the central horizontal of tube) of interior umbrella rib 83.The scheme of interspersed each figure feature of combination is many in addition, and the implementer can arrange by oneself, and no longer gives an example.In addition, when interting the feature of above each figure of combination, the implementer can according to circumstances rearrange wall thickness, inclination angle and the umbrella disk diameter of synthetic full skirt 5, and the moulding of tubular extension (such as several knuckles more than the cutaway view projection line).
Cap and pin insulator is rotary body (under a prerequisite of not considering the chapeau de fer first half) absolutely almost, and the benefit that adopts this design is both to have saved material to be convenient to processing, does not reduce the insulating capacity of insulator again.In like manner, in above four accompanying drawings, synthetic full skirt 5 and its tubular extension (comprising bonding plane) also all are designed to the rotary body with the rotating shaft of existing insulator corotation.That is to say that the profile of overlooking of synthetic full skirt main body of the present invention is circular; The tubular extension is formed by combining by hollow Rotary-table (rotating shaft of insulator is in hollow, down together), hollow cylinder basically.To overlook profile be regular polygon or ellipse if the implementer insists on synthetic full skirt main body manufactured, and can implement the present invention too; Even interstitial hole deliberately is arranged on the position of departing from the middle also can implements the present invention.Be formed by combining if the implementer insists on the tubular extension manufactured by hollow prismoid, hollow prism, also can implement the present invention's (such as hollow cylinder of replacing accompanying drawing 4 with the positive shuttle-shaped column body of the hollow that 24 inclines are arranged).The alternative of this simple geometric shape very many (such as make a certain section of tubular extension with hollow billiard table system), this specification is difficult to exemplify one by one, but all should belong to scope of the present invention.Crucial part of the present invention is, bonding plane between the lower surface of the top of tubular extension and the umbrella disk of existing insulator should be a circumferentia round the closure of steel pin 2, is round the circumferentia of the closure of the Tian'anmen Square (the not necessarily annular on the geometry meaning) as a certain ring road of Beijing.So, just can guarantee that synthetic full skirt 5 and its tubular extension play the effect of the creepage distance that prolongs existing insulator.
The technical literature of introducing synthetic full skirt agent structure is existing many.The main body of synthetic full skirt of the present invention is by the porose fimbriatum in the certain thickness centre of having of silicon rubber manufacturing (comprising that gradient is zero fimbriatum and bowl-type fimbriatum).The structure of synthetic full skirt can be open type or closed type (referring to No. 90227039.7 patents).Open type is convenient to the bonding construction of insulator of bunchiness, and the reliability of closed type is higher.The present invention recommends to use closed type, and is plotted in each accompanying drawing.When implementing to transform for the insulator that used on electric power line pole tower, the present invention advises earlier insulator being disassembled, transport to carry out in the workshop bonding, to guarantee bonding quality.
When concrete enforcement is of the present invention,, the reinforcement of spoke-like can be set at the lower surface of each synthetic full skirt for improving the intensity of synthetic full skirt; For dumping rainwater, can the edge of dripping be set in the outer of each synthetic full skirt; Dodge for strengthening creepage distance or anti-icing (rain), the diameter of synthetic full skirt can be greater than the umbrella disk diameter of existing insulator; For making things convenient for insulator transportation and lifting construction, the diameter of synthetic full skirt can be less than the umbrella disk diameter of existing insulator; For strengthening creepage distance, can one or more annular umbrella ribs that stretch out be set downwards at the lower surface of synthetic full skirt.
The dynamo-electric intensity height of synthetic full skirt, low, the anti-galvanic corrosion damage of cost ability that the synthetic full skirt that high-temperature silicon disulfide rubber is made is made than room temperature vulcanized silicone rubber are strong, are first-selection.The implementer also can use high-intensity room temperature vulcanized silicone rubber manufacturing to synthesize full skirt, if can reduce the fund input of purchase of equipment with the casting method manufacturing.
Adhesive technology between synthetic full skirt of silicon rubber and the existing insulator is ripe prior art.Implement for convenient, suitably be described below:
The silicone rubber kinds adhesive of all temps sulfuration all is suitable for bonding between the synthetic full skirt self of silicon rubber and synthetic full skirt of silicon rubber and the glass (or enamel) in principle, can guarantee that bonding plane has enough mechanical strengths and electric insulation intensity.
Surface preparation before the gluing is crucial.To enamel or glass cementation face, total requirement is a cleaning dry oil free fat, general available acetone wiping, gluing behind the airing.If will further improve adhesive strength, can be earlier carry out surface coarsening and handle and use the acetone wiping with methods such as sandblasts, apply silane coupling agent KH-550 silane coupler then, gluing again behind the airing.
To the bonding plane of the synthetic full skirt of silicon rubber, can be earlier with after the degreasing of acetone equal solvent cleaning again with one of following two methods coating silane coupling agent: 1, the trichloroethylene solution of the metatitanic acid tert-butyl ester of coating 5%-10%, cool in after gluing; 2, coating Nanjing University-42 silane coupler, gluing behind the airing.In case of necessity can be earlier with polishing alligatoring bonding planes such as emery cloth, wood files before the coating silane coupling agent.If have ready conditions, it is better to carry out surface activation process with plasma.
Behind two bonding plane gluings, position contact immediately, compress and remain to adhesive solidification (or the location encapsulating, and remain to adhesive solidification).If use the single-component room-temperature vulcanized silicone rubber adhesive, after finishing, bonding process should leave standstill about 15 days, treat that the adhesive solidification rear in deep is removable by bond.
Top cover for the tubular extension that synthesizes full skirt installs to the outside of the existing a certain umbrella rib of insulator and the structure (accompanying drawing 4 etc.) mutually bonding with this outer surface, can be connected with existing insulator by its contraction power of tying tight with thermal contraction silicon rubber or the synthetic full skirt of cold contraction silicon rubber technology manufacturing.These prior arts have been widely used in transformer station's pillar and the equipped synthetic full skirt job site of bushing insulator, also are widely used in the cable end job site.
Use the synthetic full skirt of thermal contraction silicon rubber technology assembling, between the contact surface of connected two objects (promptly existing insulator and synthetic full skirt), still want coating adhesive, to help two connection and sealings between the surface, the bonding force of keeping the existing adhesive of power of two objects connections this moment also has the convergent force of silicon rubber, and this specification claims that this technology is that thermal contraction is adhesively fixed.
Use the synthetic full skirt of cold contraction silicon rubber technology assembling generally not use adhesive, keep that power that two objects connect has only the convergent force of silicon rubber this moment and the bonding force that do not have adhesive.Be the sealing between the contact surface of realizing connected two objects, between two contact surfaces, be coated with the insulated enclosure cream of no bonding force (or not having bonding force substantially) usually.That is to say that this connection has not belonged to bonding category.Owing to can adopt this kind method of attachment to implement the present invention, above used " bonding " wording of this specification can be used " fixing " instead, to apply for corresponding coverage.This specification claims that this method of attachment is that cold contraction is fixed.The insulated enclosure cream of no bonding force has multiple, they mostly are the paste dope that does not solidify for a long time greatly, be widely used in the field relevant with cable, reference product is the HY-1 type optical cable core filling paste of Taihu Lake, Wuxi communication material factory production or 296 silicone grease of Sichuan morning twilight chemical research institute production.Adopt the advantage of this syndeton to be, suspension insulator that fix with it is still unaged when synthetic full skirt is aging, enter when changing synthetic full skirt operation the synthetic full skirt desiring to scrap but also needn't require great effort again and root out adhesive solidification thing (insulated enclosure cream can continue to use or fall with solvent scouring) of not only having torn easily.The silicon rubber tubulose thing that elasticity is good gives expansion on machine and built-in helically wound plastic support bar withstands its shape, extract support bar during site operation out, then silicone rubber tube can shrink and tie tight on by coated object, and this is cold contraction silicon rubber technology.This shows, with this process implementing when of the present invention, should select for use best in quality and silicon rubber that modulus of elasticity is suitable and arranging properly shrinks size to obtain the satisfied contraction power of tying tight.In addition, can be before assembling with epoxy resin the coated outer surface for the treatment of of the umbrella rib of existing insulator be done the shape finishing and made it to be beneficial to and tie tight fixingly earlier, treat to refill after the epoxy resin cure typing and fit in full skirt.(if the implementer insists on use adhesive with the synthetic full skirt of cold contraction silicon rubber technology assembling the time, also be not can not).
Except that silicon rubber, also can make synthetic full skirt of the present invention by cold shrinking process with ethylene-propylene rubber.Ethylene-propylene rubber is the good insulation performance elastomer.Being widely used in the job site of cable terminal and medial head with the ethylene-propylene rubber electric cable accessories of cold shrinking process manufacturing, wherein much is the tube that has synthetic full skirt.
Below the manufactured materials of synthetic full skirt of the present invention is made some supplementary notes.
At first silicon rubber is remake some explanations.
The said silicon rubber of this specification (Silicone rubber) also is translated into silicone rubber or polysiloxane rubber sometimes.It comprises many kinds, such as dimethyl silicone rubber, methyl vinyl silicone rubber, methyl phenyl silicone rubber, fluorosioloxane rubber, nitrile silicone rubber, ethyl silicon rubber, phenylene silicone rubber etc.The invention relates to the invention of product, the silicon rubber that the silicon rubber of finally making product is sulfuration (also can be called solidify or crosslinked) is also sometimes referred to as the silicon rubber.
Roughly process with the synthetic full skirt of compression molding manufactured is: high-temperature sulfuration silicon rubber raw rubber → batching (the adding various additives) → mixing → moulding of heating in metal die is also once vulcanized → is heated and post-cure → finishing → finished product.Additive commonly used has vulcanizing agent, coupling agent, age resister, pigment and filler, and filler commonly used has reinforcing agent (silicon dioxide etc.), fire retardant (aluminium hydroxide etc.) etc.Except that die pressing, can also use injection moulding, the synthetic full skirt of cast molding manufactured.Making silicone rubber products is prior art, and this specification is no longer too much introduced.
It is a kind of that the material that can make synthetic full skirt of the present invention is far above silicon rubber.After the technology prejudice in the above-mentioned insulator design was corrected by this specification, the implementer can select for use the good macromolecular compound insulating material of multiple elasticity to make synthetic full skirt of the present invention.Below attempt different materials illustrated.
Can select for use sulfurized natural rubber to make synthetic full skirt of the present invention.Sulfurized natural rubber is also referred to as rubber, is a kind of insulating material, and its electric breakdown strength can reach more than the 20kV/mm, and good elasticity is arranged.When synthesizing full skirt, should note choosing age resistor and antiozonant, to increase the service life with the rubber manufacturing.When making synthetic full skirt of the present invention, can carry out bonding with room temperature vulcanized silicone rubber class adhesive or polyurethane tackifier between it and the existing insulator with rubber.
Can also select for use based on the silicon rubber of silicon rubber and the blend of thermoplastic resin and make synthetic full skirt of the present invention (the silicon rubber quality should be more than 4 times of resin quality), such as blend of blend, silicon rubber and the poly-silicon phenylene oxosilane of silicon rubber and poly blend, silicon rubber and ethylene-vinyl acetate copolymer etc.The elasticity and the insulating properties of this class blend are good, with carrying out bonding with room temperature vulcanized silicone rubber class adhesive between the synthetic full skirt of its manufacturing and the existing insulator.
Can also select the blend of silicon rubber and other rubber for use and make synthetic full skirt of the present invention with rubber, such as the blend of silicon rubber and ethylene propylene diene rubber and with the blend of rubber (can improve the mechanical strength of silicon rubber and reduce cost, be applied in the manufacturing field of keyboard, rubber roll), silicon rubber and natural rubber also with rubber (can improve the mechanical strength of silicon rubber) etc.In order to silicon rubber is these two kinds of blend of main body and with carrying out bonding with room temperature vulcanized silicone rubber class adhesive between the synthetic full skirt of rubber manufacturing and the existing insulator.
Can also select for use the ethylene-vinyl acetate copolymer elastomer to make synthetic full skirt of the present invention.Ethylene-vinyl acetate copolymer is the EVA resin again, and vinyl acetate ratio wherein becomes the EVA elastomer when suitable, because it has thermoplasticity, is called thermoplasticity EVA elastomer again.The EVA elastomer has good flexibility, the elasticity as the rubber, the pliability under the good severe cold low temperature, good chemical stability, ageing-resistant, anti-ozone, nontoxic.It is again the good insulation performance material, and electric breakdown strength is generally more than 15kV/mm.The EVA elastomer was widely used already in cables manufacturing industry and shoemaking.With carrying out bonding with EVA hot melt adhesive adhesive between the synthetic full skirt of EVA elastomer manufacturing and the existing insulator.Ambient temperature, adhesive temperature should have been regulated and control during bonding operation and by the sticky object temperature, to guarantee bonding quality.
The synthetic full skirt of EVA elastomer is adapted at the lower area of temperature and uses, in order to improve the elastomeric softening point of EVA, enlarge the area of application, full skirt is synthesized in the blend manufacturing of available EVA elastomer and other (non-EVA) rubber, such as blend of blend, EVA elastomer and the silicon rubber of blend, EVA elastomer and the ethylene propylene diene rubber of EVA elastomer and natural rubber etc.Be to carry out bonding with EVA hot melt adhesive adhesive between the synthetic full skirt of these three kinds of blend manufacturings of main body and the existing insulator in order to the EVA elastomer.
