Abstract

The invention discloses a preparation method of composite fire-resistant glass with a gel interlayer. The preparation method comprises the following steps: firstly, synthesizing a polybasic composite flame retardant from phosphate, aluminium oxide, a boron compound and polybasic ethanolamine; secondly, preparing a refractory filler polybasic composite flame retardant, alum, magnesium chloride, a gel agent acrylamide, an initiator potassium persulfate, and sodium hydrogen sulfite into aqueous solutions respectively, standing, filtering, and keeping filtrate for standby use; finally, preparing a polyacrylamide gel solution at room temperature, filling the gel solution which is not polymerized to form gel into a middle interlayer of a hollow glass structural component, and sealing a filling port after cross-linking polymerization is performed on the gel solution to form the gel and the gel is completely cured, so as to prepare the composite fire-resistant glass. The preparation method of the composite fire-resistant glass is simple in process; the gel interlayer has a good bonding property; the prepared composite fire-resistant glass with the polyacrylamide gel interlayer has good physical and chemical properties, has high transparency in normal use, and has high fire resistance.

Description

With the preparation method of the composite fireproof glass of gel interlayer

 

Technical field

The present invention relates to a kind of preparation method of flame resistant glass, be specifically related to a kind of preparation method of composite fireproof glass.

 

Background technology

Flame resistant glass, because having printing opacity and fire-proof function concurrently, has been widely used in the building components and fittings such as fire partition, fire window, fire resistant doorsets, plays the effects such as the daylighting of simple glass, heat insulation and sound insulation at ordinary times, plays the effect stoping fire spread when fire.At present, the flame resistant glass that domestic and international market uses is divided into single-sheet fire-resistant glass and the large class of composite fireproof glass two from version, and the transparent sandwich composite fireproof glass made with grouting method in the latter accounts for the overwhelming majority.The key technology of grouting method transparent sandwich composite fireproof glass is the preparation of transparent sandwich material.

 

Summary of the invention

The object of the invention is to, provide a kind of preparation method of the composite fireproof glass with gel interlayer, technique is simple, and the caking property of gel interlayer is good, and under normal operating condition, transparency is high, and refractory heat-insulating is effective.

With a preparation method for the composite fireproof glass of gel interlayer, it comprises the following steps:

One, with phosphate, aluminium oxide, boron compound and many monoethanolamines synthesis multiple elements design fire retardant;

Two, by refractory filler multiple elements design fire retardant, alum, magnesium chloride, gel acrylamide and initiator potassium persulfate, sodium hydrogensulfite are mixed with the aqueous solution respectively, leave standstill 12h, and filter, filtrate is for subsequent use;

Three, the hollow glass structure part of intermediate course is manufactured with, for subsequent use;

Four, under room temperature, preparation polyacrylamide gel liquid, pours in the intermediate course of hollow glass structure part when coagulant liquid is not yet polymerized and forms gel, treats that coagulant liquid carries out cross-linking polymerization, form gel and solidify rear sealing grouting mouth completely, obtained composite fireproof glass.

The preparation method of the composite fireproof glass with gel interlayer provided by the invention, its beneficial effect is, technique is simple, the caking property of gel interlayer is good, the obtained composite fireproof glass good physical and chemical properties with polyacrylamide gel interlayer, under normal operating condition, transparency is high, and fire resistance is strong.

 

Detailed description of the invention

Below in conjunction with an embodiment, the preparation method of the composite fireproof glass with gel interlayer provided by the invention is described in detail.
