Problems solved by technology

However, in the actual use process, it is found that the preparation of fireproof insulating glass is troublesome, and the fireproof performance of the existing fireproof glass is still lacking. Now there are also people who inject combustion-supporting resin into the insulating glass to increase the fireproof performance. Although such glass has good fireproof performance, it is not transparent. lacking

Abstract

The invention discloses a preparation method of fireproof glass. The method comprises the following steps of firstly preparing sheet glass, clamping a transparent organic film between the two pieces of sheet glass, and performing bonding and fixing to form a glass sheet; performing edge sealing on the periphery of the glass sheet through glass cement to form sealed hollow glass, and reserving an extraction opening in the side edge; vacuumizing the hollow glass in the extraction opening, and sealing the extraction opening to obtain semi-finished fireproof glass; conveying the semi-finished fireproof glass into a coating device, arranging a plurality of groups of coating rollers which relatively rotate up and down in the coating device, and coating the outer side of the fireproof glass witha salt solution when the semi-finished fireproof glass passes through the coating device; and heating the coated fireproof glass in a toughening furnace, keeping the temperature for a period of time,taking out the fireproof glass, and naturally cooling the fireproof glass to the room temperature to obtain the finished fireproof glass. The invention provides fireproof hollow glass with excellent fireproof performance.

Description

technical field [0001] The invention relates to the technical field of fireproof glass production, in particular to a preparation method of fireproof glass. Background technique [0002] Fire-resistant glass first appeared in Europe in the early 1970s and is one of the architectural safety glasses. With the rapid development of economy in this century and the high-speed development of human scientific and technological civilization and material and cultural living standards, countries all over the world have higher and higher requirements for building residential buildings and public buildings. Countries such as Britain, France, and Germany in Europe have successively formulated regulations such as "Code for Fire Protection Design of Buildings", "Test Methods and Standards for Fire Protection Performance of Building Parts" and "Code for Fire Protection Design of High-rise Civil Buildings". The safety performance of glass has promoted the pace of research and development of ...
