Problems solved by technology

[0009] The present invention aims to overcome the problems in the prior art that the glass on both sides of the insulating glass is single-layer glass, there is no heat-insulating and flame-retardant interlayer between the single-layer glass, and the single-layer glass is easily broken and scattered in case of fire, and the safety is low. Provided is a double-layer glass with double-layer glass on both sides of the insulating glass. The double-layer glass is filled with a heat-insulating and flame-retardant interlayer. After the glass is broken, it can still adhere to the resin layer, which can maintain its original state and has high safety performance. A kind of preparation method of fireproof insulating glass

Abstract

The invention relates to a preparation method of glass, in particular to a preparation method of fireproof hollow glass. The preparation method comprises the steps that firstly, a groove is corroded on the back face of the glass through a photolithography technique and a glass corrosion technique, then surface ion exchange is conducted, sodium ions on the surface of the glass are substituted withcesium ions and potassium ions, then the back faces of two pieces of tempered cesium-potassium glass are opposite, the position between the two pieces of the tempered cesium-potassium glass is filledwith boronic silicon modified polyvinyl butyral resin, the tempered cesium-potassium laminated glass is obtained, the position between the two pieces of tempered cesium-potassium laminated glass is aerated with dry fire extinguishing gas and sealed with a sealing strip, and the fireproof hollow glass is obtained. The fireproof hollow glass has the following beneficial effects that (1) the internalstress on the glass surface is small, the binding strength of the laminated glass is higher, and the stability of the glass is good; (2) the fireproof property, the flame retardant property and the heat insulation property are outstanding, and the safety is high; and (3) automatic fire extinguishing can be conducted.

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing fireproof insulating glass. Background technique [0002] At present, with the continuous development of technology and the changing of people's aesthetic concept, glass materials are more and more widely used in daily life. It is widely used in the construction industry, especially for partitioning rooms and housing curtain walls. However, the currently used glass often bursts when encountering an open flame, which cannot prevent fire prevention, and due to the good thermal conductivity of the glass, the user may be scalded by the scorching glass when escaping. [0003] Fireproof glass is mainly used in fire prevention to control the spread of fire or to isolate smoke. It is a measure-type fireproof material, and its fireproof effect is evaluated by fire resistance. It is a special glass that has been processed and treated by a special process and can main...
