Problems solved by technology

Although the composite fire-resistant glass prepared by the interlayer method has heat insulation, earthquake resistance, and impact resistance, its fire resistance is generally poor; while the perfusion fire-resistant glass prepared by the grouting method has good fire-resistant integrity and good heat insulation effect. However, due to the large amount of water contained in the grout, the thickness and weight of the fireproof glass are large, which limits its installation cost and scope of use.
At the same time, because the custom-made double-glazed box is filled with fireproof liquid to form a gel layer during processing, this makes the processing of poured fireproof glass complicated, and the composite glass processed according to size cannot be cut at will.

Abstract

The invention discloses a fire-proof glass membrane based on PAM-inorganic medium phase separation and polymerization and a preparation method and application of the glass membrane. The preparation method comprises the steps that 30-60 weight parts of saturated aqueous solution of acrylic amide and N,N'-methylenebis acrylamid mixture and 40-70 weight parts of saturated aqueous solution, with the pH larger than 9, of an inorganic medium are sufficiently mixed, then 0.2-1.5 weight parts of initiator with the mass fraction of 10% is added into the mixed solution, after uniform mixing, tape casting or molding is conducted, and then the fire-proof glass membrane based on the PAM-inorganic medium phase separation and polymerization is obtained through polymerization, wherein the inorganic mediumis formed by one or two of water glass and aluminum salt in any proportion. Under high-temperature firing of a fire disaster, the water-proof glass membrane can form a fire-proof material covering layer, the covering layer is made to become an inorganic water-proof skeleton, the mechanical strength, the fire resistance and the thermal-insulation effect of the fire-proof layer are improved, and the mechanical integrity and the thermal-insulation fire resistance can be kept in the fire disaster.

Description

technical field [0001] The invention relates to the field of fireproof material manufacturing, in particular to a fireproof glass film based on PAM-inorganic matrix phase separation polymerization and its preparation method and application. Background technique [0002] Fireproof glass is a kind of safety glass. It is a special glass with transparency that can block flames, smoke, heat radiation, prevent flames from spreading, and maintain integrity and stability within a certain period of time. It should also have certain resistance Impact strength, it can still play a protective role for a certain period of time under the flame baking at 1000 ℃. Fire-resistant glass is now being widely used in large-scale public building partitions, fire compartments, outdoor curtain walls and other building parts. Fire-resistant glass is characterized by transparency, which satisfies the harmony and unity of building fire protection and architectural aesthetics to the greatest extent. ...
