Abstract

The invention relates to a preparation method of a high-weather-resistance fireproof glass interlayer material and belongs to the technical field of fireproof materials. According to the preparation method, anhydrous aluminum trichloride and ethyl orthosilicate as reaction precursors and anhydrous diethyl ether as an oxygen donor are used for performing non-hydrolysis preparation of a gel material, a silica sol material is modified through the gel material, through silane modifying, the organic hydrophobic group is more easily grafted on the surface of aerogel, a dense structure is formed through gel coating so as to serve as a defoaming agent material of the gel interlayer, the bubble rate of the material is reduced effectively, meanwhile, by effective bonding between the gel material andthe interlayer gel, the dense structure of the material is effectively improved, and the mechanical property of the material is further improved.

Description

technical field [0001] The invention relates to a preparation method of a high-weather-resistant fireproof glass interlayer material, which belongs to the technical field of fireproof materials. Background technique [0002] Fireproof glass refers to a functional glass that is transparent and can block and control heat radiation, smoke and flames, and can also control the spread of fire-resistant defoaming gel liquid and smoke insulation. To be precise, fire-resistant glass, as a special glass, needs to be able to maintain its integrity and heat insulation under the specified fire-resistant test conditions. Fire-resistant glass can be defined as a glass system consisting of a defoaming gel liquid sheet or multiple sheets of transparent or translucent glass, sealing strips and fixing materials, which can meet the fire performance requirements. Defoaming gel solution Generally speaking, fireproof glass is a member of safety glass, which is made by treating float glass with de...
