Description

A kind of antiultraviolet composite fireproof glass

Technical field

The utility model relates to a kind of antiultraviolet composite fireproof glass, belongs to composite fireproof glass manufacturing technology field.

Background technology

Composite fireproof glass refers to ordinary plate glass above to two or two and the compound functional safety glass of transparent fireproof material function layer. Transparent fireproof material function layer mainly contains two classes, and a class is the hydrogel that organic material forms, and another kind of is alkali silicate fire prevention film. Composite fireproof glass effect is can effectively reduce or avoid the person and property to be endangered under Fire Conditions.

The composite fireproof glass just existing is in the market not suitable as exterior wall and uses, its reason is that composite fireproof glass is being subject under UV-irradiation condition for a long time, composite fireproof glass functional layer easily becomes milky white and produces the light aging phenomenons such as bubble, causes product quality impaired. Solve composite fireproof glass anti-ultraviolet function, there are two kinds of approach, the first is at the compound one deck doubling glass of composite fireproof glass exterior wall sunny slope, intercept and absorb ultraviolet ray by PVB organic material, the second be in composite fireproof glass fire prevention gel layer body, add UV absorption material utilize in as patent 201110321264.3 ESCALOL 567 and zinc oxide absorb with intercept ultraviolet.

Utility model content

The purpose of this utility model is to provide a kind of antiultraviolet composite fireproof glass, can improve the problem that prior art exists, by titania/silica composite bed being covered to basalis inner side, and transparent fireproof material function layer body adds titanium dioxide, utilize the ultraviolet ray of anatase titanium dioxide absorption of crystal, effectively prevent that compound glass is subject to ultraviolet ray to affect generation qualitative change.

The utility model is achieved through the following technical solutions:

A kind of antiultraviolet composite fireproof glass, comprise 2 layers of basalis and be arranged on the transparent fireproof material function layer between the basalis described in 2 layers, the titania/silica composite bed arranging between described transparent fireproof material function layer and described basalis.

In the utility model, nano-anatase mine-titanium oxide layer can effectively absorb and intercept ultraviolet ray, avoids ultraviolet ray to cause the structural change of fireproof bonding agent and the light aging phenomenon of the bubble that bleaches that causes.

Further, for realizing better the utility model, titania/silica composite bed is that anatase titanium dioxide crystal Nano sol and silicon dioxide gel composite spraying are on basalis surface;

Further, for realizing better the utility model, silica and titanium dioxide mol ratio 1:(1-3 in titania/silica composite bed);

Further, for realizing better the utility model, titania/silica composite bed bed thickness is between 150-250nm;

Further, for realizing better the utility model, described transparent fireproof material function layer is to be that 3.4-4.0 sodium silicate solution and nanometer anatase titania are composited by modulus;

Further, for realizing better the utility model nanometer anatase titania particle diameter at 10-20nm;

Further, for realizing better the utility model, described basalis is Pu Bai or ultrawhite safety glass.

The utility model compared with prior art, has following beneficial effect:

(1) the utility model, by adopting anatase crystal titanium dioxide to absorb ultraviolet ray, prevents that ultraviolet ray from affecting the fire protecting performance of compound glass;

(2) in the utility model, titania/silica composite bed is that loose structure not only has the effect of the ultraviolet of absorption, and is of value in addition transparent fireproof material function layer and substrate laminated sheet row bubble.
