Problems solved by technology

At present, the research on special fireproof glue for composite fireproof glass at home and abroad is in the basic research stage, and it is generally prepared by directly stirring the mixture of water / water glass. It is found that the fireproof glass prepared by using this kind of fireproof glue not only has a large number of microbubbles, The apparent quality is poor and other problems, and there are problems such as insufficient hardness of the fireproof adhesive layer, which seriously affects the use effect and service life of fireproof glass

Abstract

The invention discloses a composite fireproof glass preparation method which comprises the following steps: (1) pretreating glass surface; (2) spraying fireproof glue on the glass surface; (3) buckling glue layers of two pieces of glass and putting into a vacuum device to be vacuumized; (4) heating the vacuum device and keeping a vacuum state; (5) stopping heating, keeping a vacuum environment, shutting down a vacuum air pumping system when temperature reduces to 45 DEG C and cooling to normal temperature to obtain the composite fireproof glass. The composite fireproof glass prepared by the composite fireproof glass preparation method disclosed by the invention has good fireproof performance, long service life, no microbubble, high transmittance and suitability for varieties of occasions.

Description

technical field [0001] The invention belongs to the technical field of fireproof glass, and in particular relates to a preparation method of composite fireproof glass. Background technique [0002] As the pace of urbanization is getting faster and faster, the building windows of houses are getting bigger and bigger. Elegant, beautiful and functionally safe glass components are gradually being favored by domestic and foreign designers, which directly leads to various types of safety glass. And special glass is developing rapidly in the architectural glass industry. Architectural glass has gradually developed from simply being used as a lighting and decorative material to a composite of multiple functions such as light control, room temperature adjustment, noise reduction, and improvement of the living environment. Among them, insulating glass is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the weigh...
