Novel vitrified brick gum

Abstract

The invention discloses a novel vitrified brick gum. The novel vitrified brick gum comprises slurry and powder. The weight percentage ratio of the slurry to the powder is 1: 3.5-4.5. The slurry comprises the following components in parts by weight: emulsion 15-55 parts, silicon modified aqueous epoxy resin 18.5-53 parts, a preservative 0.5-3.5 parts and cellulose 0.5-2 parts. The powder comprises the following components in parts by weight: titanium dioxide 1-8 parts and an inorganic filler 15-35 parts. The silicon modified aqueous epoxy resin comprises the following components in parts by weight: aqueous epoxy resins 8-20 parts, an auxiliary agent 5-15 parts, a modifying agent 5-15 parts and catalyst 0.5-3 parts. The slurry and the powder are organically combined according to a certain ratio, the adhesion strength of the vitrified brick gum is improved, adhesion requirements of vitrified bricks can be met completely, the vitrified bricks can be adhered to different base materials, the novel vitrified brick gum is simple to construct, and the problems of hollowing, breaking, dropping and the like during adhesion of the vitrified bricks are solved effectively.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel back glue for vitrified tiles. Background technique [0002] At present, ceramic bricks with high water absorption rate (5% to 10%) used in home decoration, large clubs, supermarkets and interior and exterior decoration of buildings have low strength, single style and small size, so they are no longer suitable for high-speed development. At the same time, vitrified bricks have been widely used in the architectural decoration market because of their advantages of low water absorption, high strength, specifications and varieties. [0003] Vitrified bricks are made of quartz sand and mud fired according to a certain proportion, and then polished brightly but do not need to be polished. The surface is as smooth and translucent as a glass mirror. It is superior to ordinary glazed tiles, polished tiles and general marble in terms of water absorption, edge straightness, bendin...

AI Technical Summary

Problems solved by technology

However, there are many types of vitrified tile adhesives on the market at present, and the quality varies. After use, there will be problems such as hollowing, shelling, and falling off. ;Climate changes in heat and cold, so that the cementitious material is affected by deformation, resulting in cracks at the interface between the cementitious material and vitrified bricks, causing the vitrified bricks to fall off
