In the building field, when bonding smooth interfaces such as glass plates, the glass plates are bonded with the surfaces of ceramic tiles, and are usually fixed by adopting a glass cement bonding mode. When the glass glue is in contact with water, the glass glue is often blackened, so that the bonding force is reduced, the glass integrally falls off, potential safety hazards are caused, and the service life of the glass is influenced. The traditional cement yellow sand has poor bonding effect with glass, and has low bonding strength, so that the actual use requirement cannot be met. And when two groups on the silane coupling agent molecules are wetted, a certain chemical reaction can be generated to form a tightly-crosslinked bonding complex, the interface bonding property is improved, the bonding strength is improved, and the silane coupling agent molecules are introduced into mortar to achieve the effect that 1 plus 1 is larger than 2. The microwave curing of the fly ash can lead Si-O bonds in the fly ash glass body to be in a high-energy state, and the network structure of the glass body is easy to disintegrate, thereby improving the activity of the fly ash. The invention aims to adopt the bonding mortar to realize the bonding technology between the surfaces of the glass plate and the ceramic tile and between the glass plate and the glass plate surface so as to solve the problems that the glass cement turns black when meeting water and the bonding force is reduced.
