Abstract

The invention belongs to the technical field of building materials, and in particular relates to a two-component tile grout. During the use of the present invention, firstly, the mixed polymer in component A can form a film on the surface of the gap, and at the same time enhance the bonding performance with the tiles, and secondly, the additives added can be cured with the mixture in component B. Deposition, filling the gaps of tiles, and using the additives in component B can well combine the metal ions in it, and can be compounded with composite glue to form a good filling effect, thus solving the problem of the current gap filling materials. Problems of cracking and poor water resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a two-component tile grout. Background technique [0002] In modern buildings, tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. In order to avoid hollowing between tiles due to thermal expansion and contraction, there must Leave a gap that needs to be filled with tile grout. [0003] The development of joint filler materials is constantly evolving with the improvement of application and understanding, from the initial white cement to the present polymer modified cement-based joint sealant, epoxy joint sealant, beauty joint agent, etc. There are many problems in the application process of these materials, such as cement-based joint sealant is prone to alkali return and whitening phenomenon, the price of epoxy joint sealant is high, it is not easy to be suitable fo...
