Composite fire-retardant glass laminating solution, preparation method thereof and composite fire-retardant glass

Abstract

The invention relates to a composite fire-retardant glass laminating solution, a preparation method thereof and a composite fire-retardant glass, and belongs to the field of safety glass. The raw materials of the composite fire-retardant glass laminating solution include the following substances in parts by weight: 25-150 parts of potash water glass, 100 parts of deionized water, 0.2-1 part of charring agents, 0.1-0.5 part of charring auxiliary agents, 0.01-0.05 part of defoaming agents, 0.1-0.2 part of flatting agents and 0.1-0.5 part of cross-linking agents. According to the invention, the laminating solution with a flow direction easily controlled is prepared in such a way that the synergistic effect is generated among the components of the laminating solution by improving the formula of the laminating solution, so that the corrosion of the laminating solution on added coatings, such as an anti-reflection coating and the like, is prevented; the bubbles of a composite fire-retardant glass interlayer are eliminated, and the high-property microbubble-free composite fire-retardant glass which achieves the transmittance of 84%-85% and the fire-retardant time as high as about 90 minutes and is provided with the anti-reflection coating is prepared.

Description

technical field [0001] The invention belongs to the field of safety glass, in particular to a lamination liquid for composite fireproof glass with an antireflection layer and a composite fireproof glass laminated by the lamination liquid. Background technique [0002] Fire-resistant glass is a kind of high-end architectural glass. In addition to some properties of ordinary glass, it also has the properties of controlling fire spread, smoke insulation and heat insulation. Fireproof glass is divided into composite fireproof glass and single piece fireproof glass. At present, composite fireproof glass consists of two or more pieces of flat glass and a fireproof adhesive layer sandwiched between the flat glasses. When encountering a fire, the fireproof adhesive layer absorbs a large amount of heat generated by the fire, rapidly foams and expands, and forms a heat-insulating fire-resistant and heat-insulating foam layer. At the same time, the fireproof adhesive layer can also bo...

Problems solved by technology

[0005] In order to improve the performance of the composite fireproof glass, it is necessary to install other coatings on the outer glass surface of the composite fireproof glass, such as anti-reflection coating, referred to as the anti-reflection layer. It is not easy to control, and the laminating liquid is easy to flow around or even splash when pressurized. When the composite fire-resistant glass has other coatings such as anti-reflection layers, the laminating liquid flows on the coating and is easy to corrode the coating; at the same time, the existing lamination The liquid itself is easy to generate bubbles, which leads to poor apparent quality of the composite fireproof glass and insufficient hardness of the fireproof layer, which seriously affects the use effect and service life of the composite fireproof glass
