Except the high-temperature resistant silicone colloid that the modification of linear backbone silicon systems organic moiety cageization is obtained after liquid；
2. preparation is built-in with electrode, inner surface is coated with containing aluminium graphite cast iron mold of the insulation except adhesion coating, in 1)
2. fine copper silk spinning that step prepares is made into the layer net that smooth vertical and horizontal and aperture is length of side 5mm square holes, is equidistantly spread using 5mm as interlamellar spacing
If in a mold；
3. by 1. high-temperature resistant silicone colloid that step obtains with 1) in the raw material that 1. prepare of step be uniformly mixed, obtain
Mixture；
4. 3. mixture that step is obtained pours into the mold for being equipped with fine copper silk screen, mold is then placed in vacuum electric heating
Mixture is energized to after 350 DEG C are warming up in treatment furnace, in stove as kinematic viscosity 5mm2/s-10mm2The fluid of/s, Ran Houkai
Beginning, (magnetic agitation is mainly used for stirring or the simultaneously liquid of heating stirring low sticky degree with the rate magnetic agitation of 60rpm-80rpm
Body or solidliquid mixture.Its basic principle is using the magnetic field principle that identical charges repel each other, there is a natural attraction between the sexes, is promoted and placed using magnetic field
Magnetic substance carries out circumferential running in a reservoir, so as to achieve the purpose that agitated liquid.Coordinate heating and temperature control system,
It can be heated according to specific requirement of experiment and control sample temperature, maintain the temperature conditionss needed for production, ensure liquid mixing
Reach demand), this plastid of acquisition glass after stirring；
3) this plastid of glass tempering
1. this plastid of glass that flow-like is filled in mold is gas-cooled under the nitrogen of 5bar-6bar, that is, obtain physics
This plastid of tempered glass；
4) glass essence surface modification
1. 1) 3. polyacrylate that step in prepares is heated to molten condition；
2. by the stage 3) polypropylene of molten condition that is 1. obtained to step of physical toughened this plastid of glass infiltration for obtaining
In acid esters；
3. 2. physical toughened this plastid of glass for having infiltrated polyacrylate that step is obtained takes out, treat its surface in half
Minute surface is mechanically processed as during fluid state, freedom from cracking tempered glass i.e. needed for acquisition completely after cooling.
The freedom from cracking tempered glass manufactured using the above method, this plastid composition include silica by weight
85 parts -90 parts, 5 parts -8 parts of boron oxide, 2 parts -3 parts of sodium oxide molybdena, linear backbone silicon systems organic moiety cageization be modified high temperature resistant
5 parts -8 parts of the fine copper silk of 6 parts -10 parts of organosilicon colloid, diameter 0.1mm；This liposome surface is also compounded with layer polypropylene acid
Ester.
Compared with the prior art, the present invention has the following advantages as a result of said program：(1) using existing
Be not applied to the borosilicate glass of building in technology, and be low boron class borosilicate glass therein, i.e. SiO2-B2O3-
R2(in routine techniques, this kind of glass is usually using its light, electricity, hot property, for front glass, heat-resisting cooker, peace for O systems glass
Small jar glass, neutral density glass, electric-vacuum glass, optical glass, LCD substrates, solar panel and heat collector), it is ground according to correlation
Study carefully, the coefficient of expansion of such glass is that minimum in all glass and heat dissipation performance is best.(2) present invention is also in glass
The modification of linear backbone silicon systems organic moiety cageization is added in matrix, and (the cageization modification specifically just refers to the shallow lake of straight-chain
Powder forms cylinder mould shape knot by the moiety segments of the epoxy-modified object of high energy and the effect aftercondensated product of catalyst sodium hydroxide
Structure) high-temperature resistant silicone colloid, which it is epoxy-modified to add high energy based on heat safe linear polysiloxane
Object, and polycondensation reaction is carried out under the action of catalyst sodium hydroxide, acquisition is with soft elastic and opposite with vitreum close
The high-temperature resistant silicone colloid of sum subsequently not by conventional heating but carries out glass this plastid exclusively by electrical heating processing
On the one hand melting is that make use of principle conductive under borosilicate glass high temperature, be on the other hand also to promote under electric power effect
Part-S-O- keys in glass polymerize with organosilicon colloid, and colloid is made to be integrally formed with glass, and with molecule or a small amount of molecules
Group's form is solidificated in glass this plastid, obtains flexible buffering colloid, is aided with the low-expansion coefficient of borosilicate glass itself
With heat dissipation performance and soft fine copper silk from solidity energy, the overall performance system of a freedom from cracking is constituted.(3) covered by surface
The processing of film, is the outer Extended lift cushion space of the present invention, and reduces impact force, reduces tearing tendency, polyacrylate
Adhesive ability is strong, itself is soft flexible, and translucency is good, good weatherability, not easy to change and aging and in the prior art never
Material applied to glassware field.(4) very thin fine copper silk screen built in, according to correlative study, hot tearing is mainly due to temperature
Excessive or internal stress is excessive causes for difference, and the internal stress under regular situation during most hot tearings is only slightly born beyond tempered glass
The limit, only because tempered glass itself brittleness in routine techniques is high and without ability, therefore the present invention is increased admittedly certainly
Very thin fine copper silk can effectively reduce the possibility of hot tearing, and according to the practice of applicant, hot tearing of the invention can be solely routine
The 5%-6% of tempered glass.
