Abstract

The invention discloses ultralow-temperature pouring sealant fireproof glass, which comprises a plurality of layers of raw glass sheets, flame-retardant adhesive tapes and ultralow-temperature pouring sealant, the peripheries of the multiple layers of raw glass sheets are sealed by flame-retardant adhesive tapes to form a glass containing cavity, and the ultralow-temperature pouring sealant is poured into the glass containing cavity; the ultralow-temperature pouring sealant is prepared from the following raw materials: a silica sol solution, organic silicon, potassium hydroxide, nano hydrophilic particles, a charring agent, a charring aid, a storage stabilizer, a defoaming agent, a plasticizer and glycerol. The invention discloses a preparation method of the ultra-low-temperature pouring sealant fireproof glass, which comprises the following steps: adding potassium hydroxide into a silica sol solution in a stirring state, adjusting the temperature to 60-80 DEG C for reaction, carrying out vacuum defoaming, then adding organic silicon for reaction, adding nano hydrophilic particles, a charring agent, a charring auxiliary agent, a storage stabilizer, a defoaming agent, a plasticizer and glycerol, uniformly stirring, filling the glass accommodating cavity, and curing to obtain the ultralow-temperature pouring sealant fireproof glass.

Description

technical field [0001] The invention relates to the technical field of fireproof glass, in particular to an ultra-low temperature potting glue fireproof glass and a preparation method thereof. Background technique [0002] At present, the internal stress of ordinary glass is poor, the temperature tolerance is poor, and the softening point is about 500°C. Tempered glass cannot withstand the impact of thermal stress and is prone to instant bursting; since March 30, 2018, the Ministry of Housing and Urban-Rural Development announced No. 35 Since the revision (2018 edition) of "Code for Fire Protection Design of Buildings" GB50016-2014 and "Code for Fire Protection Design of High-Rise Civil Buildings" GB50045-95 (2005 Edition), the fire protection requirements for fire-resistant doors and windows and fire-resistant doors and windows have been further upgraded. [0003] Fire-resistant glass is a key component of buildings. The fire-resistant glass on the market, such as monolithi...
