Application of redispersible latex powder in mortar

The rapid development of society has led to the increase of mortar demand, ordinary mortar has been difficult to meet the needs of social development, energy saving, environmental protection and high efficiency has become the trend of mortar development. The development of mortar is inseparable from the application of redispersible emulsion powder. Different functional mortars can be produced by adding redispersible latex powder with different characteristics.

Due to the ideal combination of polymer binder and cementitious binder, it is possible to prepare products meeting high requirements for the construction industry. These requirements include the adhesion, impact strength, flexural strength, air permeability, flexibility and water repellency of various substrates. Through the use of redispersible latex powder, various properties can be improved, such as reducing elastic modulus, increasing adhesion, increasing cohesion, increasing bending strength, enhancing flexural strength, improving impact resistance, reducing water absorption, improving wear resistance, enhancing durability, improving water retention and improving construction performance. Mortar is widely used in the construction industry. It plays the role of bonding, decoration, cushion and protection with thin layer, which involves almost every aspect of construction and decoration engineering. The traditional mortar is usually mixed in the construction site, and the mortar has poor impermeability and large shrinkage rate, which is the weak link of the construction quality problems such as paint cracking, peeling, shelling and leakage.

However, with the addition of redispersible latex powder, premixed dry mixed mortar emerges as the times require. At present, dry mortar mainly includes: dry concrete, masonry mortar, and special mortar (color mortar). Masonry mortar is mainly used for walls, such as masonry clay bricks, concrete blocks, structural masonry, stone, etc. at the same time, it can also be used for indoor and outdoor wall plastering engineering. Special mortar mainly includes bonding mortar, plastering mortar, self leveling mortar, facing mortar, repair mortar, etc., which can be used for plastering of walls and floors, pasting of decorative materials, ceramic tiles, thermal insulation materials, repairing of waterproof layer, pavement, concrete structure, etc. According to different conditions and uses, more than 70 kinds of special mortar have been developed. With different mortars, redispersible latex powder can be roughly divided into five types: external insulation mortar, ceramic tile adhesive, self leveling mortar, repair mortar and putty.
