History of Redispersible Latex Powder and Ceramic Tile Adhesive
2023-07-28 17:16As early as the 1930s, polymer binders were used to improve the performance of mortar. After the polymer lotion was successfully put on the market, Walker developed the spray drying process, which realized the provision of lotion in the form of rubber powder, becoming the beginning of the era of polymer modified dry mixed mortar.
For over 100 years, ceramic tiles have been used as coverings for walls and floors. Nowadays, they have become indispensable decorative materials. Tiles of various sizes, patterns, and grades can be seen everywhere.
With the advancement of ceramic tile technology, the body of ceramic tiles is becoming increasingly dense and larger in size, posing great challenges for the laying of ceramic tiles. How to make large-sized ceramic tiles stick more firmly and ensure long-term laying reliability has become a new focus of attention in the field of modern decoration.
Bonding materials (such as macromolecular polymers) are wetted on the surface of ceramic tiles, and a wetting state is formed between the two, which makes the molecular spacing between the two very small. Finally, a huge Intermolecular force is formed at the bonding interface, which tightly combines the bonding materials and ceramic tiles. With the advancement of ceramic tile technology, increasingly dense ceramic tiles are difficult to provide more gaps for mechanical interlocking to form anchoring. However, intermolecular bonding is becoming increasingly important.
Our RDP forms a polymer network in mortar products, connecting ceramic tiles and mortar through Intermolecular force, so that even if the ceramic tiles are denser, they can stick firmly to the mortar.
The redispersible latex powder product is a water-soluble redispersible powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid.
Redispersible Latex Powder has film-forming property. 50% aqueous solution forms lotion shape and forms plastic film after being put on glass for 24 hours. The formed film has a certain degree of flexibility and water resistance.
Redispersible latex powder has high performance: it has high bonding ability, unique performance, and outstanding waterproof performance, good bonding strength, endowing the mortar with excellent alkali resistance, which can improve the adhesion, flexural strength, plasticity, wear resistance, and workability of the mortar. In addition, it also has strong flexibility in crack resistant mortar
