Problems solved by technology

[0004] In the prior art, the fireproof glue solidified by the fireproof liquid has many deficiencies in fireproof performance, such as water glass, which has a low modulus, low solid content, and high water content, which leads to a large number of fireproof glue in the composite fireproof glass. Microbubbles directly affect the appearance quality, optical properties, hardness and toughness of composite fireproof glass. More importantly, the existence of microbubbles greatly reduces the fireproof performance of composite fireproof glass, which seriously affects the use effect and quality of composite fireproof glass. service life

Abstract

The invention discloses a fireproof liquid of composite fireproof glass and a preparation method thereof and a composite fireproof glass, relates to a field of safety glass, and solves the problems that a fireproof glue-line has micro bubbles and bad flame resistance. The main method of the invention is as follows: polyol, a functional monomer, deionized water and an auxiliary agent are mixed for obtaining a first mixed emulsion, silica is added, and a silica dispension emulsion is obtained; styrene, methyl methacrylate and butyl acrylate monomer are mixed, a second mixed monomer emulsion is obtained, a cross-linking agent, deionized water, the silica dispersion emulsion and an initiator are added, and a soap-free seeded emulsion is obtained after reaction; acrylic acid, styrene, methyl methacrylate and butyl acrylate monomer are mixed, a third mixed monomer emulsion is obtained, deionized water, the initiator, the cross-linking agent and the soap-free seeded emulsion are added, and a soap-free emulsion with core-shell structure is obtained after reaction; a potassium hydroxide solution and an auxiliary agent are added, after mixing, standing and refiltering, an obtained filtrate is the fireproof liquid of composite fireproof glass. The fireproof liquid provided by the invention can be solidified into a fireproof glue, which has good fireproof performance without micro bubbles.

Description

technical field [0001] The invention relates to the field of safety glass, in particular to a fireproof liquid for composite fireproof glass, a preparation method thereof and a composite fireproof glass prepared by using the fireproof liquid. Background technique [0002] Safety glass is an important new building material, mainly divided into tempered glass, laminated glass, bulletproof glass, anti-theft glass, fireproof glass, wired glass, protective glass and film glass; fireproof glass is a kind of building exterior with fireproof function Wall or door and window glass, which can keep for a long time without bursting under the impact of 1000 ℃ flame, so as to effectively prevent the spread of flame and smoke, help to find the fire at the first time, and ensure that the affected people have enough time to evacuate the scene. It is the most effective and safest fireproof glass product at present; fireproof glass is divided into composite fireproof glass and single piece fir...
