Heat insulation type composite fireproof glass and preparation method thereof

Abstract

The invention discloses heat insulation type composite fireproof glass and a preparation method thereof. The composite fireproof glass is made of two layers of monolithic glass bonded by an adhesive,wherein each of the two layers of monolithic glass comprises the following raw materials in part by weight: 60-90 parts of silicon dioxide, 1-15 parts of aluminum oxide, 1-15 parts of sodium oxide, 1-15 parts of calcium oxide, 0.01-10 parts of germanium dioxide, 0.1-10 parts of potassium oxide, 0.2-10 parts of sodium chloride, 0.1-10 parts of zirconium dioxide, 20-80 parts of magnesium chloride, 5-40 parts of potassium chloride, 0.3-10 parts of an organophosphorus flame retardant, 1-10 parts of ferrous sulfate, 1-25 parts of gadolinium oxide, 1-25 parts of lithium oxide and 1-30 parts of cerium dioxide. The heat insulation type composite fireproof glass and the preparation method thereof, disclosed by the invention, have the beneficial effects that all the raw materials are made into a mixture, and each of the two layers of monolithic glass is made by high temperature forming, annealing, cooling and physical toughening; when the composite fireproof glass formed by the combination of the two layers of monolithic glass prepared by adopting the raw materials and the process through the adhesive is in a high-temperature environment and even a fire, the fireproof performance is excellent, the fire resistance time of the heat insulation type composite fireproof glass is greatly prolonged, and the heat insulation property is excellent.

Description

Technical field [0001] The invention relates to the technical field of glass, in particular to a heat-insulating composite fireproof glass and a preparation method thereof. Background technique [0002] Glass is a necessity in people’s lives. The chemical composition of ordinary glass is Na 2 SiO 3 , CaSiO 3 , SiO 2 Or Na 2 O·CaO·6SiO 2 The main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to separate wind and transmit light. It is a mixture. With the progress of science and technology, there are more and more varieties of glass and more and more functions. Among them, fire-proof glass has been widely used in fire-proof partitions, fire-proof windows, fire-proof doors and other building components because of its light transmission and fire-proof functions. It usually plays the role of ordinary glass in lighting, heat insulation and sound insulation, and plays a role in fire. Prevent the spread of fire. ...
