Fireproof adhesive, preparation method thereof and composite fireproof glass containing fireproof adhesive

Abstract

The invention relates to a fireproof adhesive, a preparation method of the fireproof adhesive and composite fireproof glass containing the fireproof adhesive. The fireproof adhesive includes the following raw materials: 20 to 30 parts of nano silicon dioxide sol, 50 to 65 parts of a water glass solution, 0.5 to 1.0 part of a charring agent, 0.1 to 0.3 part of a charring auxiliary agent, 0.3 to 0.8 part of a heat-resistant stabilizer, 10 to 20 parts of an anti-condensing agent, 0.05 to 0.1 part of an ion fixing agent, 0.3 to 0.5 part of a storage stabilizer, 0.1 to 0.5 part of a defoaming agent and 0.15 to 0.3 part of a cross-linking agent; wherein the moisture content of the inorganic transparent fireproof adhesive is 30-50%. The water content of the transparent fireproof glue is as low as 30-50%, and the fire resistance of the composite fireproof glass is effectively improved; meanwhile, certain flowing performance is ensured, so that pouring is facilitated. Heat insulation composite fireproof glass and non-heat-insulation type composite fireproof glass prepared from the transparent fireproof adhesive both have the characteristics of good appearance quality, good weather resistance, high visible light transmittance, excellent cold flow resistance and the like.

Description

technical field [0001] The invention relates to the technical field of fireproof glue, in particular to a fireproof glue, a preparation method thereof and a composite fireproof glass containing the fireproof glue. Background technique [0002] In addition to some properties of ordinary glass, fire-resistant glass also has the properties of controlling fire spread, smoke insulation and heat insulation, which provides valuable rescue time for effective rescue in the event of fire, and minimizes the loss of personnel, property, and buildings. property loss. Fire-resistant glass can protect escape and rescue personnel from heat radiation and minimize the destructive power of fire. Due to the recent frequent fires in some well-known large buildings at home and abroad, people are paying more and more attention to the R&D, production and use effects of composite fire-resistant glass. [0003] The earliest research on composite fireproof glass is organic grouting composite firepro...

AI Technical Summary

Problems solved by technology

Organic grouting composite fireproof glass has better low temperature resistance, but poor ultraviolet radiation resistance, high temperature resistance, hardness and cold flow resistance

Inorganic composite fireproof glass is divided into inorganic air-drying composite fireproof glass and inorganic grouting composite fireproof glass. Among them, air-drying composite fireproof glass is also better in low temperature resistance, and its hardness and cold flow resistance are particularly outstanding, but it also has the same UV radiation resistance and durability. The high temperature performance is relatively poor, it is difficult to apply to complex and harsh environments such as outdoors, and the production process is complicated, and microbubbles are prone to be generated during the production process, which affects the appearance quality; while the inorganic grouting composite fireproof glass has ultraviolet radiation resistance and high temperature resistance. Very excellent, hardness and rheological performance are worse than organic grouting composite fireproof glass, although the low temperature resistance is not as good as organic grouting composite fireproof glass and inorganic air board composite fireproof glass, but it is much higher than the national standard requirements, and after recent years of development , low temperature performance is greatly improved
