Abstract

The invention provides a fireproof glue liquid matrix and a preparation method thereof, and a fireproof glue liquid and a preparation method thereof. The fireproof glue liquid matrix is prepared from silicon dioxide and a lubricating matter, wherein the lubricating matter is a copolymer of aromatic olefin and / or acrylate. The fireproof glue liquid is prepared from the fireproof glue liquid matrix. The prepared fireproof glue liquid has the advantages that the viscosity is only 50 to 1000cp, and the fireproof glue liquid can be used for preparing composite fireproof glass with fireproof layer thickness less than 1mm. A fireproof layer prepared by the fireproof glue liquid has the advantages of good fireproof and heat isolation properties, high hardness, high transmittance and good anti-ultraviolet property.

Description

technical field [0001] The invention relates to fireproof glue and a preparation method thereof, belonging to the field of fireproof safety glass. Background technique [0002] Fireproof glass is a kind of glass used for building exterior walls or doors and windows with fireproof function. It not only has the conventional properties of ordinary glass, but also has specific properties such as controlling the spread of fire, insulating smoke and heat. At present, fireproof glass is mainly divided into four types: composite fireproof glass, special fireproof glass, hollow fireproof glass and high-strength single-layer cesium potassium fireproof glass. Among them, the composite fire-resistant glass (Laminated Fire-Resistant Glass) has good light transmission performance, and is classified as Class A fire protection because of its excellent fire integrity (Integrity, E) and heat insulation (Insulation, I) Glass, in a fire, can protect the escape personnel and rescue personnel fr...
