A kind of tcughened glass insulator of the multilayer gluing according to manufactured by above-mentioned manufacturing method, the insulator include one
The one compound glass layer and multiple glued layers, center portion staggeredly interted is made of glass.
The insulator at least can anti lightning abrupt slope peak value 5000kV/s；- 50 DEG C~500 can be born in normal loading
The impact of DEG C iterative cycles；Still sustainable normal loading after zero degree self-destruction；Bearing stress is not less than 300Mpa；U-shaped notch shock
Intensity is not less than 25J/cm2；Light transmittance is not less than 80%.
Compared with prior art, the invention has the following advantages that due to being utilized well by managing formula preparation entirely
Melt temperature and invalid temperature are higher than 1300 DEG C again after glued liquid out is dry and hard, be successfully realized glass replace with gluing liquid it is cold
But, completely new multilayer gluing tcughened glass structure has been prepared；It has mentioned a kind of complete glass formula and its has strengthened ingredient, also
Detailed process flow and intensifying method, process is clear, definite principle, is easily achieved；Since profiled insulation has multilayer tempering
Glass structure, multilayer tempering glass structure centre is there are also increase binding force and with the adhesive of powerful pooling feature, as branch
It supports, pull, stress conduction, in addition every layer of glass structure of glass insulator of the invention all coolings are quickly, that is, using
There is very huge pressing stress on steel process, glass insulator surface layer, can offset part foreign impacts power, and there is very high tension in inside, can support
Anti- external world's part of impact force, therefore this glass insulator strong shock resistance, have since adhesive also plays every layer of glass structure
The effect pullled and fixed, in addition tempered glass zero point self-destruction after will not peel off naturally, still retain significant proportion binding force and
Mechanical strength, even if so that this glass insulator have occurred zero point self-destruction, can also continue to complete basic function, until maintenance when it is saturating
It is replaced after crossing the high vitreum of light transmittance and can be visually seen crackle, it is easy to use；According to correlative study, iron-phosphorus-carbon system tempering
Glass good-toughness, its ontology toughness obtains considerable raising after glass insulator of the invention has dissolved in toughening element, in addition, this
Invention has selected optimal procedure parameters during the sintering process, the thermal stress and structural stress of itself insulator remnants is all lower,
It joined vibration processes again in later period polishing treatment, homogenize internal stress, improve the uniformity of overall performance, reduce scarce
Mouthful sensibility, and the major reason that impact flexibility of the present invention is high, impact flexibility be four times of conventional tempering glass with
On, ten times or more of porcelain insulator；Due to using steel process (making flow-like glass metal rapid cooling), glass of the invention is exhausted
Center portion is also uncolled when edge sublist layer cools down, and forms oneself however the tensile stress of uniform bearing stress layer and center portion, surface layer
Compression can obviously increase fatigue life, and part of impact force is offset when by foreign impacts, the tensile stress of center portion can also
Extraneous impact force can be resisted, under comprehensive use, long service life of the invention, comprehensive mechanical performance are good；It is refined due to strengthening
Process carries out under nitrogen protection entirely, participates in without impurity, and hot tearing is inclined in process for technical maturity, method of the invention
To low, micro-crack is few, therefore the light transmittance of final finished is high, excellent electrical properties.
