The thickness of glass layer 2 made of dimension winding is 1-10mm.
In the preparation method of insulator of the present invention, dedusting is cleared up to the porcelain core 1 of manufactured including original segment and glazing section
Afterwards, porcelain core 1 is slowly heated to 80-150 DEG C, preferably 100-120 DEG C.The heating of porcelain core 1 can use microwave steam heater
Deng device.Meanwhile the glass fibre of silicon-coating alkyl size is heated to 100-140 DEG C, preferably 110-120 DEG C, then make
Glass fibre after heating is wound to rapidly to the original segment of porcelain core 1 with wrapping machine, the thickness of glass layer 2 wound is 1-
10mm.The thickness of glass layer 2 can be configured according to the needs of different product.Winding can increase glass fibers after heating
The coupling effect of dimension and ceramic core rod, but coupling agent can be caused to fail it may be noted that temperature is too high simultaneously.
In the embodiment of the present invention, in the above method, prepared by the porcelain core, bonding agent is coated with, silicon rubber umbrella forming step
Specially：
It is prepared by porcelain core：Porcelain embryo is made, sand glazing on the both ends of porcelain embryo is fired, mounting flange, polishing, obtains porcelain core 1,
The part of sand glazing is the glazing section of porcelain core 1 on the porcelain embryo, and remainder is the original segment of porcelain core 1；
Bonding agent is coated with：The surface of porcelain core 1 coating silicon rubber bonding hot vulcanization agent after glass fibre is wound, bond layer
3 thickness 0.1-5mm；
Silicon rubber umbrella is molded：Porcelain core 1 after coating adhesive is put into mould, is injection moulded silicon rubber umbrella 4.
The preparation method of the insulator of the present invention, first prepares porcelain core 1：Use wet method or isostatic pressed dry fabrication mud cylinder, porcelain
The manufacturing process steps of plug are：By raw mineral materials such as kaolin, alumina, feldspar and other clays by ball milling, cross and screen out
Iron, press filt, pugging, drying in the shade, repaired biscuit, what the processing step such as drying obtained that wet production obtains does not burn till semi-finished product porcelain billet part, or
Person iron removaling of sieving, is granulated, compacting, repaired biscuit obtains the composite rod insulator plug of isostatic pressed dry method manufacture by ball milling
Semi-finished product.The diameter of plug is determined with length according to different product.Porcelain embryo is repaired according to the diameter needed for porcelain core by trimming machine,
By the both ends for the porcelain billet fixed, upper sand glazing treatment, glazing techniques are to drench glaze, porcelain embryo interlude not glazing as requested；Then use
Industrial Stoves hang burning and fired, to ensure the axiality of porcelain core rod.Bake and by detecting qualified plug, by cutting, make
With cement mucilage binding metal flange, conserved, after the polishing of surface, obtain the finished product porcelain core of used in composite insulator.Polishing is only to original
Beginning section (i.e. non-glazing part) is polished, and polishing causes porcelain core surface is fine and smooth uniformly not have projection, so in winding glass fibers
Fiber is more evenly distributed during dimension, and last adhesive effect is better.The bending failure load of porcelain core is permitted to use Ying Li≤65MPa.Thus
Obtained porcelain core 1, its surface interlude be without glazing treatment, the qualified porcelain core 1 of grinding process.The porcelain core of the present invention
1, preferentially produced using static pressure technology, the porcelain core 1 prepared compared to wet method, quality is more stable, and intensity is higher, and to intensity requirement
Not high porcelain core 1, wet method can be used to prepare.
After the completion of prepared by porcelain core 1, glass fiber winding step is carried out, as stated above by glass fiber winding in porcelain core 1
On, glass layer 2 is made.Then bonding agent application step is carried out, silicon rubber bonding hot vulcanization agent is spread evenly across glass
The surface of fibrous layer 2, coating layer thickness 0.1-5mm, it should be ensured that smear in place and smear uniform.Automation spray dress can be used
Put even application silicon rubber bonding hot vulcanization agent, it is ensured that smear layer consistency of thickness.During coating adhesive, glass fibre will be wound
Porcelain core be preheated to 100-120 DEG C, then carry out bonding agent coating.The present invention can use and first assemble end coupling, then
The scheme of glass fibre is wound, end coupling is flange, the metal flange that stainless steel can be used to prepare；It is glued using cement
Agent bonds together metal flange and porcelain core 1.
Then, the plug for being coated with bonding agent is put into the mould of silicon rubber injector, injected using usual way
Shaping so that silicon rubber umbrella 4 is combined together with porcelain core 1, and the temperature for injecting vulcanization is normally controlled between 150-170 DEG C.
After depanning, cleaned, the step such as deflashing, obtain finished product.
The present invention composite insulator, using porcelain core 1 be used as main body plug, have preferably rigidity, resistance type ability with
Ageing resistance.Meanwhile retain unglazed original segment on the surface of porcelain core 1, compared to glaze paint porcelain core rod, surface work can be increased
Performance, glass fibre is more closely wound, adhesive is more closely bonded with plug, prevent aging, depart from
Phenomena such as generation.The present invention sets glass layer 2 between porcelain core 1 and silicon rubber umbrella 4, using glass fibre as one kind
The material of middle transition, because glass fibre main component is SiO2, and the main chemical composition of porcelain core rod also includes SiO2, because
This two kinds of materials have good compatibility；And by the physics mode of winding, porcelain core 1 is set to be incorporated in glass layer 2
Together so that the glass fibre as intermediate layer can be securely attached together with porcelain core, avoid the occurrence of aging phenomenon.Meanwhile
Glass layer 2 relies on the higher surface-active and surface roughness of glass fibre with silicon rubber umbrella 4, compared to porcelain core rod and silicon
The bonding of rubber umbrella cover 4, there is stronger adhesive effect.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
