Description

Double-layer toughened glass for fire warning

Technical Field

The utility model relates to a glass especially indicates a double-deck toughened glass with conflagration early warning function.

Background

Most public places are beautiful, toughened glass is mostly adopted as a door and window material, and when a fire disaster happens, the traditional toughened glass has no fireproof function, so that the traditional toughened glass can burst when burned, which not only easily causes damage to human bodies, but also causes the fire to spread. On the other hand, sometimes a fire disaster occurs indoors, and due to the fact that the inner side of the glass is covered with the shielding object, people on the outer side cannot find the fire disaster in time, and therefore the fire cannot be extinguished in time.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a double-deck toughened glass of conflagration warning has the function of conflagration warning to better shockproof sound-insulating ability has. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides a conflagration warning double-deck toughened glass, includes two toughened glass panels, be equipped with two-layer PVB membrane between two-layer PVB panels, be equipped with the perm board between the two-layer PVB membrane, be equipped with the reflection stratum between perm board and one of them one deck PVB membrane and be equipped with the temperature between another layer PVB membrane and change the colour film, be equipped with fretwork department on the temperature changes the colour film, the fretwork department has irritated fire prevention silica gel.

Further, the reflecting layer is an infrared reflecting film.

Further, the reflection direction of the reflection layer is the thermochromic film side.

Further, the thermochromic film had a color change temperature of 68 ℃.

Further, the thermochromic film is transparent when the thermochromic temperature is lower than the color change temperature, and is red when the thermochromic temperature is higher than the color change temperature.

(III) advantageous effects

Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, be equipped with temperature-sensitive discoloration membrane between two-layer toughened glass, make toughened glass automatic discolour when the conflagration takes place, realize the warning to crowd on every side, and be equipped with the reflection stratum, can reflect the heat to temperature-sensitive discoloration membrane on, improve its programming rate, accelerate the rate of discolouing, and in time sparse crowd and deal with the conflagration, be equipped with PVB membrane and pamm board between two toughened glass panels simultaneously, effectively improve glass's shock-resistant sound-insulating ability.
