Thin type fireproof glass and preparation thereof

Abstract

The invention discloses a thin fire-resisting glass and a method for the production thereof. The thin fire-resisting glass of the invention is glued by a flat glass and compounded by pouring fire-proof transparent glue, solidifying and sealing, the compositions of the fire-proof transparent glue (W%) are: gel forming agent of 5 to 15 percent, methylene-bisacrylamide of 10 to 20 percent, initiator of 0.1 to 2.0 percent, sodium chloride of 5 to 15 percent, magnesium chloride of 5 to 30 percent, aluminum phosphate of 5 to 25 percent, boric acid of 0 to 10 percent, ethanolamine of 5 to 25 percent and water of 30 to 50 percent. The fire-resisting glass of the invention is mainly used for fireproof and soundproof building partitioning facilities such as fire-resisting and soundproof doors and fire-resisting and soundproof walls and windows, and has good sound insulation, transmittance, waterproofing and weathering resistance performances, and can meet the requirements of high-grade building fireproof materials with rather high fireproof demand.

Description

technical field [0001] The invention relates to the field of laminated glass manufacturing, and more specifically relates to a thin type A fireproof glass and a preparation method thereof. Background technique [0002] At present, the heat-insulating Class A fire-resistant glass is composite fire-resistant glass, water-dividing glass bonding and gel-type fire-resistant glass. Due to the poor water resistance, weather resistance and fire resistance of water glass bonded fireproof glass, it is rarely used in the market. The gel-type fireproof glass has high transparency, simple process, good water resistance and weather resistance, and is widely used. However, the thickness of commercially available gel-type fire-resistant glass is relatively thick. When doing fire-resistant experiments, the fire-resistant glass glue will form a foam layer by the evaporation heat of water to insulate heat. When the back temperature reaches 100°C and the water evaporates, the heat-insulation l...

However, the thickness of commercially available gel-type fire-resistant glass is relatively thick. When doing fire-resistant experiments, the fire-resistant glass glue will form a foam layer by the evaporation heat of water to insulate heat. When the back temperature reaches 100°C and the water evaporates, the heat-insulation layer will turn gray. Shape, poor strength, easy to wear fire
