A kind of liquid tile glue and preparation method thereof

Abstract

The invention discloses liquid tile glue and a preparation method of the liquid tile glue. The liquid tile glue mainly comprises acrylic acid copolymer emulsion, styrene-acrylic emulsion, polyvinyl alcohol, modified polyoxyethylene, a thickening agent, a wetting agent, other assistants, and deionized water. According to the liquid tile glue, specific kinds and contents of the assistants and the wetting agent are selected, the performance of the liquid tile glue can be improved significantly; the liquid tile glue is good in bonding strength, water resistance, ageing resistance and freeze-thawing resistance, can effectively improve and increase construction efficiency and yield and is worthy of popularization and application in production.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a liquid tile adhesive and a preparation method thereof. Background technique [0002] Ceramic tile is a widely used building material in the field of building materials. Whether it is floor or wall decoration, ceramic tile is a relatively common building material, and tile adhesive is a key material in the process of tile bonding, especially wall tile bonding. , its formulation technology has a significant impact on the service life of tiles. The existing tile adhesives generally use cement, quartz sand and wood fiber as the main raw materials, and then add calcium carbonate, cellulose ether, rubber powder, starch ether, etc. to improve . In the process of use, the required amount of tile adhesive is large, and the composition contains a large amount of cement, resulting in the performance of the overall slurry being restricted by cost, and because the adhesive will nee...

Problems solved by technology

Due to factors such as temperature, wind speed and operators during the application process, when the tiles are pressed into the tile adhesive, the tile adhesive has a certain degree of surface crusting, and the wettability between the tile adhesive and the tile is poor. There is a certain gap on the back when it is just pasted. Even if the bonding strength between the tile adhesive and the tile in the later wetting part is high, the gap caused by poor wettability in the early stage is still the weak link of the tile paste, and it is also the tile. A major cause of hollowing and shedding

[0004] The choice of tile adhesive is the key factor for tiles used in interior decoration. Due to the smooth surface of tiles, if the tile adhesive effect is not good, it will affect the overall smoothness and produce irregular reflections. The existing tile adhesives cannot ensure that they are compatible with tiles After bonding, it resists vibration and temperature changes. After a period of time (usually winter and summer alternately), there will be peeling and peeling, which will cause the tile body to fall off seriously, which will cause great hidden dangers to normal use.
