Description

It prevents fires compound low iron glass

Technical field

The utility model is related to functional glass fields, and in particular to a kind of compound low iron glass of fire prevention.

Background technology

Fireproof composite glass have good fire protecting performance, especially can be achieved on A class heat insulation type flame resistant glasses fire insulation, Insulation requirement.In actual use, when running into fire, physics occurs for the fire prevention glue-line in composite fireproof glass and chemistry becomes Change, this layer is caused gradually to be deteriorated for the cohesion of adjacent glass layer；And the glass of heated fragmentation is easy to fall off, and will make Glue-line of preventing fires is exposed to live in one side.At this moment prevent fires glue-line fire insulation heat insulation and meet the whole fire insulation of flame resistant glass Heat insulation can all substantially reduce.

Low iron glass is a kind of high-transparent glass, is mainly used for the higher equipment of transparency requirement.Since low iron glass is former Typically contain that impurity is less in material, what is controlled in melting process of raw material is fine so that low iron glass has with respect to simple glass There is more homogeneous ingredient, internal impurity is less, thus greatly reduces the probability that may be revealed after tempering, and light transmittance is reachable 95%, there is quality as glittering and translucent crystal.It is low since the iron-holder in raw material is only the 1/10 even lower of simple glass Iron glass absorbs the green band in visible ray with respect to simple glass less, it is ensured that the uniformity of glass colour.

Low iron glass is applied in fireproof composite glass, the transparency of flame resistant glass is added, expands use scope.

Utility model content

In order to solve the problems, such as in background technology, the utility model is intended to provide a kind of with excellent heat insulation and good The compound low iron glass of fire prevention of good translucency, including at least layer glass, the periphery of the layer glass is equipped with banding item, described Butyl rubber tight bond is used between banding item and layer glass, it is fireproof glass layers that external one layer is leaned in the layer glass, One layer is low iron glass layer close to the inner portion, and the energy saving layer of low-e Low emissivities, institute are equipped between the fireproof glass layers and low iron glass layer The both sides for stating the energy saving layer of low-e Low emissivities are equipped with antireflective coating, and fire prevention composite film, institute are equipped on the outside of the fireproof glass layers Stating low iron glass layer includes the low iron glass piece bonded successively, fire prevention glue-line and low iron glass piece.

Further, the thickness of the fireproof glass layers is 6~12mm.The fireproof glass layers are caesium potassium flame resistant glass Layer.The thickness of the low iron glass layer is 8~18mm.

Further, the fire prevention composite film includes dielectric layer and barrier layer.

Further, the fire prevention glue-line is silica fire prevention glue-line.

The advantageous effects of the utility model are：In the technical solution of the utility model, because adding low-e The energy saving layer of Low emissivity, is the membrane system product that multiple layer metal or other compounds composition are plated in glass surface, and film plating layer has To the characteristic of its visible ray high transmission and centering far infrared high reflection, and both sides be equipped with antireflective coating, make its with it is common Glass and traditional coated glass for building are compared, and have excellent heat insulation and good translucency；Because equipped with banding Item so that compound glass enhances the effect of heat-insulated fire insulation while having good globality；Because low iron glass layer wraps again It includes two layers of low iron glass piece and positioned at intermediate fire prevention glue-line, further enhances fire insulation every thermal property.
