Fireproof hollow glass, manufacturing method and application

Abstract

The invention belongs to the technical field of fireproof glass, and discloses fireproof hollow glass, a manufacturing method and application. The fireproof hollow glass is provided with two pieces ofglass, bonding sealing between the glass and spacing bars, and bonding sealing at the periphery of the glass; the two pieces of glass are equal in length and width; at least one piece of glass is fireproof glass; the fireproof glass is preferentially installed on the indoor side; the spacing bars are directly adhered to the periphery of the adhering surface of the first piece of glass in sectionsto form a closed frame, or the spacing bars are adhered to the periphery of the adhering surface of the first piece of glass after being manufactured into a spacing frame; the second piece of glass is adhered to the other surfaces of the spacing bars; the peripheries of the two pieces of glass are aligned; and the glass and the spacing bars are adhered together through sealant or structural adhesive or double-sided adhesive tape or edge sealant. The fireproof hollow glass is simple in structure, good in fireproof performance and long in service life, and the fireproof hollow glass not only has a fireproof effect, but also has good heat insulation and sound insulation effects.

Description

technical field [0001] The invention belongs to the technical field of fireproof glass, and in particular relates to a fireproof hollow glass, a manufacturing method and an application thereof. Background technique [0002] At present, fire-resistant glass is a special glass that has been processed and treated by a special process and can maintain its integrity and heat insulation in the specified fire-resistant test. Prolonged and extensive spread of smoke. Fire-resistant glass is widely used in the field of construction as lighting door and window glass, curtain wall glass, and fire-resistant window glass. With the increasing number of high-rise buildings, the demand for fire-resistant glass is also increasing. [0003] The existing fireproof glass can be divided into composite fireproof glass, single piece fireproof glass and fireproof insulating glass according to the structure, among which single piece fireproof glass is divided into traditional single piece fireproof ...

AI Technical Summary

Problems solved by technology

[0003] The existing fireproof glass can be divided into composite fireproof glass, single piece fireproof glass and fireproof insulating glass according to the structure, among which single piece fireproof glass is divided into traditional single piece fireproof glass and special single piece fireproof glass; special single piece fireproof glass refers to The glass substrate is glass with special components, mainly high borosilicate glass, aluminosilicate glass, glass-ceramic, etc. Its advantages are high softening temperature, small thermal expansion coefficient, and generally will not burst or deform due to high temperature. The disadvantage is cost High, low production capacity, expensive, difficult to promote and apply on a large scale

Ordinary single-piece fireproof glass is generally processed by super-strong physical tempering process or spraying cesium potassium solution during tempering. Its surface stress is high and can meet the requirements of fireproof glass, but high stress leads to poor stability and high self-explosion rate. There are safety hazards in the external windows of buildings; the heat insulation and sound insulation performance of single glass is poor, and it cannot meet the requirements of heat insulation and sound insulation while meeting the fire protection requirements

Composite laminated fireproof glass produced by the grouting method has relatively good heat insulation, but poor weather resistance, and is prone to whitening and fogging after being exposed to sunlight, which affects the permeability and visibility of the glass, so it cannot be used in batches For doors, windows and curtain walls with daylighting function

Existing fireproof insulating glass is generally made of a piece of ordinary glass and a single piece of fireproof glass using insulating glass production equipment according to the production process of insulating glass, that is, a piece of fireproof glass is used to replace a piece of glass in the insulating glass. The heat insulation and sound insulation effect of a single piece of fireproof glass, but its structure, sealant, structural glue, spacer frame, etc. do not consider the fireproof requirements, and still use the structure and materials used in ordinary insulating glass; when a fire occurs, the gas in the hollow layer is affected. Thermal expansion may break the glass, and the sealants, structural adhesives, and spacers used may be softened by heat, melted and lost, or even burned, causing the glass to fall off, not only failing to meet fire protection requirements, but also causing safety accidents

[0004] Through the above analysis, the existing problems and defects of the existing technology are: when a fire occurs in the existing fire-proof insulating glass, the gas in the hollow layer may be heated and expanded to cause the glass to break, and the sealant, structural adhesive and spacer frame used may be damaged. Softening due to heating, melting and loss or even burning will cause the glass to fall off, failing to meet the fire protection requirements and causing safety accidents
