Problems solved by technology

However, due to the limitation of the production process, the structure of the polymer molecular chain is destroyed after spray drying, so that the long molecular chain of the emulsion becomes a solid powder short molecular chain structure, and this process is irreversible.
Therefore, the dry powder tile adhesive greatly reduces the crack resistance and waterproof performance.
[0003] Moreover, due to the rapid development of the types and quality of facing bricks and wall materials, the water absorption of facing bricks is lower, the size is larger, and the base layer and location are more demanding.
Dry powder tile adhesives can no longer meet the market demand, resulting in the phenomenon of hollowing and falling off of many tiles, even leading to tragedies

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a binder and its preparation method and application. Background technique [0002] Dry powder tile adhesive is currently the most commonly used adhesive for pasting various types of tiles and stones on walls, floors, indoors, outdoors and other places. One of its main bonding components is redispersible rubber powder, which is processed by spray drying of polymer emulsion. However, due to the limitations of the production process, the structure of the polymer molecular chain is destroyed after spray drying, so that the long molecular chain of the emulsion changes into a solid powdery short molecular chain structure, and this process is irreversible. Therefore, the dry powder tile adhesive is greatly reduced in crack resistance and waterproof performance. [0003] Moreover, due to the rapid development of the types and quality of facing bricks and wall materials, the ...
