Abstract

The invention discloses cesium-rubidium-potassium monolithic flameproof glass and a preparation method. The preparation method comprises a process of carrying out chemical strengthening on glass, wherein chemical strengthening is carried out by placing the glass in molten salts and carrying out ion exchange by a two-step method; in the first step, the molten salt is a mixture of potassium nitrate, rubidium nitrate, potassium fluoride and potassium hydroxide, the exchange temperature is 320-360 DEG C and the heat-insulation time is 2 hours; and in the second step, the molten salt is a mixture of potassium nitrate, cesium nitrate, aluminum oxide, boron fluoride, potassium carbonate and potassium phosphate, the exchange temperature is 500 DEG C and the heat-insulation time is 3 hours. The monolithic flameproof glass product prepared by the method is stable in quality and excellent in fire resistance; in the fire resistance test, the invalidation of the monolithic flameproof glass is caused by final softening and collapsing instead of heat bursting destruction; and the fire resistance time is 120 minutes.

Description

technical field [0001] The invention relates to a single-piece fireproof glass, in particular to a cesium-rubidium-potassium single-piece fireproof glass and a preparation method thereof. Background technique [0002] Fire-resistant glass is a special glass that can maintain its integrity and heat insulation under the specified fire-resistant test conditions. Fire-resistant glass is classified according to its structure and can be divided into single-layer fire-resistant glass and composite fire-resistant glass. Composite fire-resistant glass is a special glass that is composed of two or more layers of glass or a layer of glass and organic materials, and meets the requirements of the corresponding fire-resistant grade. Composite fire-resistant glass has disadvantages such as poor light transmission and weather resistance, and its performance is not as good as that of single-layer fire-resistant glass. [0003] At present, there are mainly two types of single-piece fireproo...
