[0004] From the above patent documents and related products at home and abroad, it can be seen that the preparation process of this type of composite fireproof glass generally needs to modify silica to prepare fireproof glue with less air bubbles and lower viscosity. The preparation process of this type of product is relatively complicated and the cost is high; at the same time, according to the research of this type of product at home and abroad, the fire resistance limit of this type of product is still generally low, and there are almost no related products with low price, low overall thickness and high fire resistance limit

Abstract
The invention provides a high fire-resistant transparent fire-proof gel, comprising A component and B component, the mass ratio of A component and B component is 1.5-3:1; the A component includes a solvent, contains metal elements Hydrolyzable flame retardant modifiers, dispersants, coupling agents, antifreeze agents, preservatives and curing agents; the B component includes SiO 2 , SiO 2 The particle size is 250-500nm. The invention also discloses a simple method for preparing high fire-resistant transparent fire-proof gel and composite fire-proof glass by using the above formula. The present invention solves the complex preparation process of existing products, uneven dispersion of nanoparticles and easy sedimentation, high viscosity of fireproof gel precursor liquid and easy generation of microbubbles, low solid content of fireproof gel, high price of composite fireproof glass and fire resistance Insufficient performance and other problems, and the fire resistance limit of the composite fireproof glass prepared by using the transparent fireproof gel can reach 25-163min.
Description
technical field [0001] The invention relates to the field of composite fireproof glass, in particular to a high fireproof transparent fireproof gel, a preparation method thereof and composite fireproof glass. Background technique [0002] Fire-resistant glass refers to a type of special glass that can maintain its integrity and even heat insulation in a fire-resistant test with a specified heating curve. Composite fireproof glass is a kind of fireproof glass. It is a fireproof glass component formed by adding fireproof glue between two or more pieces of glass, making it solidify into a transparent gel, and bonding with glass as a whole. Composite fire-resistant glass has excellent heat insulation performance and can meet the corresponding fire-resistant grade requirements. It is currently the most effective and safest fire-resistant glass product. Grouting composite fireproof glass is a type of composite fireproof glass that is relatively easy to prepare, mainly including o...
