Description

Hollow glass with fireproof performance

Technical Field

The utility model belongs to the technical field of cavity glass, concretely relates to cavity glass with fire behavior.

Background

The hollow glass is a glass product formed by uniformly separating two or more pieces of glass by effective support and bonding and sealing the periphery of the glass so as to form a dry gas space between glass layers. Glass is widely applied to the field of doors and windows due to excellent heat insulation and light transmission performance. When a building encounters a fire, flames easily enter a room through a gap between the glass and the frame. The existing hollow glass has insufficient structural tightness, and after the existing hollow glass is subjected to vibration, the air tightness between the glass base layer and the spacing strips and between the glass base layer and the frame can be reduced, so that the heat insulation performance of the hollow glass is influenced, and the fireproof performance is not high.

The frame is provided with a hollow inner cavity, cesium-potassium fireproof liquid is filled in the hollow inner cavity, a through hole is formed in one side, facing the spacing strip, of the hollow inner cavity, and hot melt adhesive is filled in the through hole.

The utility model has the advantages as follows:

1. hollow glass, set up first recess, second recess and third recess on the space stop bar, when bonding space stop bar and glass basic unit, in first recess, second recess and the third recess were filled to the sealing glue film, make the gas tightness of junction higher, when taking place the vibration in the use, the sealing glue film has bigger holding power to the space stop bar, avoid the space stop bar not hard up influence hollow glass's gas tightness, more powerful in prevention flame gets into indoorly from the space.

2. Cavity glass, set up the cavity inner chamber in the frame to at the intussuseption of cavity inner chamber cesium potassium fire prevention liquid, the cavity inner chamber sets up the through-hole, and with hot melt adhesive shutoff through-hole, when the conflagration breaing out, the hot melt adhesive in the through-hole receives high temperature to dissolve, cesium potassium fire prevention liquid in the cavity inner chamber can play the effect that prevents flame from stretching from the inside clearance department of cavity glass, further improves fire prevention effect.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1

The hollow glass with the fireproof performance as shown in fig. 1-2 comprises a fireproof layer 1, a first bonding layer 2, a glass base layer 3, spacing strips 4 and a frame 5, wherein the glass base layer 3 is arranged on two sides of the spacing strips, the fireproof layer 1 is arranged on the outer side of the glass base layer, the fireproof layer is fixed on the glass base layer through the first bonding layer, and the frame is arranged on the outer side of the periphery of the glass base layer; the both sides that spacer 4 and glass basic unit correspond set up first recess 6, and the spacer sets up second recess 7 towards one side of frame, evenly sets up third recess 8 at the inner wall of second recess, bond by sealing glue layer 9 between glass basic unit and the spacer and between spacer and the frame. The fireproof layer, the first bonding layer and the sealing adhesive layer are made of high-temperature-resistant glue.
