Problems solved by technology

However, since the water absorption rate of the vitrified brick itself is lower than 5‰, it is difficult to stick it to the surface of the cement layer. Although various adhesive materials on the market can achieve the effect of sticking, their bonding strength is insufficient.

Abstract

The invention discloses a vitrified brick gum which consists of a liquid component and a powder component according to the weight ratio of 1:(1-5), wherein the liquid component comprises 25-70 percent of high polymer, 29-74.8 percent of water, 0.2-0.5 percent of preservative and 0-0.5 percent of cellulose; and the powder component comprises 30-65 percent of cement, 35-70 percent of silica sand and 0-0.5 percent of cellulose. The vitrified brick gum can be directly smeared to the back face of a vitrified brick and adhered with a cement base material, and excellent shear strength and tensile strength can be achieved after the vitrified brick gum is dried up, therefore, the problem that the vitrified brick is unstable to adhere after the cement base material is adopted is solved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to vitrified tile back glue. Background technique [0002] Vitrified tiles are made of quartz sand and mud fired according to a certain proportion, and then polished brightly without polishing. The surface is as smooth and translucent as a glass mirror. It is the hardest of all tiles. Straightness, bending strength, acid and alkali resistance, etc. are superior to ordinary glazed tiles, polished tiles and general marble. Vitrified brick is a good decorative material, used for interior decoration, has many decorative effects, such as showing noble, firm, beautiful and other effects. However, since the water absorption rate of the vitrified brick itself is lower than 5‰, it is difficult to stick it to the surface of the cement layer. Although various adhesive materials on the market can achieve the effect of sticking, their bonding strength is insufficient. . [0003] In actual us...
