Description
Technical field
The present invention relates to a kind of special glasss, more particularly, to a kind of implosion guard and preparation method thereof.
Background technique
Implosion guard is to prevent the glass of violence impact, it is to utilize special additive and intermediate interlayer
The special glass being made by machining will not be fallen easily glass is broken, because intermediate material and the other side is anti-
Quick-fried glass is sufficiently bonded together.Therefore, implosion guard can greatly reduce when meeting with violence impact to personnel and valuables
The injury of product.
Implosion guard presses the difference of production and processing technology, is divided into two classes：
Plain edition implosion guard
Plain edition implosion guard, the special glass that glass structure is mostly made into monolithic float glass by intensive treatment are strengthened
Treated, and glass surface has stronger violence impact capacity, and such glass is constantly thickened with thickness of glass, explosion-proof
Effect is constantly enhanced, and thickness is most generally 20 millimeters thick, and the glass beyond 20 millimeters or more thickness is made into implosion guard, by force
Change processing is difficult one-time-reach-place, don't fail to be prudent for selection common explosion proof glass customers group.
Once rupturing, glass just becomes fragment, cannot effectively keep out wind pressure or weight secondary pulse plain edition implosion guard.
In a strict sense, plain edition implosion guard and it is not belonging to " implosion guard " truly.
Reinforced implosion guard
Reinforced implosion guard is that folder among two panels or multi-disc float glass is pressed and use up through hot press with tough PVB film
Intermediate air is possibly discharged, be then placed in high steam kettle using high temperature and pressure remaining a small amount of air is dissolved in into glue film and
At.
Such as one kind disclosed a kind of implosion guard material and preparation method thereof, Shen Qing Publication in Chinese patent literature
Number CN105693088A, a kind of implosion guard material of the disclosure of the invention and preparation method thereof, above-mentioned implosion guard material, by
