Problems solved by technology

When this kind of bonding method encounters water, the glass glue often turns black, which reduces the bonding force, thus causing the glass to fall off as a whole, causing safety hazards and affecting the service life of the glass.
The bonding effect of traditional cement yellow sand and glass is not very good, and the bonding strength is relatively low, which cannot meet the actual use requirements

Abstract

The invention relates to bonding mortar for bonding smooth interfaces and a preparation method thereof. The bonding mortar is prepared from the following components in parts by weight: 40 to 50 partsof cement, 40 to 50 parts of quartz sand, 5 to 10 parts of latex powder, 0.5 to 5 parts of a water-retaining thickening material, 1 to 3 parts of a water reducing agent, 0 to 0.5 part of a defoaming agent, 0.5 to 1 part of an early strength agent and 2 to 10 parts of modified microwave-treated fly ash. The bonding mortar prepared by adopting the formula and the preparation method disclosed by theinvention has the advantages of good weather resistance, high tensile adhesive strength, excellent slip resistance, good water retention capacity and no bleeding phenomenon. The bonding mortar can beused for bonding smooth interfaces of glass plates and the like, and is particularly suitable for bonding the glass plates with cement-based materials and bonding glass plates with ceramic tiles in ahumid environment.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a bonding mortar for bonding smooth interfaces such as glass plates and a preparation method thereof. Background technique [0002] When bonding a smooth interface such as a glass plate in the construction field, the glass plate is bonded to the surface of the ceramic tile, and is usually fixed by glass glue bonding. When this kind of bonding method encounters water, the glass glue often turns black, which reduces the bonding force, thereby causing the glass to fall off as a whole, causing a safety hazard and affecting the service life of the glass. The bonding effect of traditional cement yellow sand and glass is not very good, and the bonding strength is relatively low, which cannot meet the actual use requirements. When the two groups on the silane coupling agent molecule are wetted, they will produce a certain chemical reaction to form a cross-linked a...
