Different dry powder mortar products have different performance requirements for redispersible latex powder. Because ceramic tiles have good decorative and functional features such as durability, waterproof and easy cleaning, their applications are very common; tile adhesives are cement-based bonding materials for pasting tiles, also known as tile adhesives. Can be used to glue ceramic tiles, polished tiles and natural stones such as granite.
The tile adhesive is composed of aggregate, Portland cement, a small amount of slaked lime and functional additives added according to product quality requirements. In the past, thick-layer mortar mixed on site was used as the bonding material for tiles and stones. This method is inefficient, consumes a large amount of materials, and is difficult to construct. When bonding large tiles with low water absorption, it is easy to fall off and the construction quality is difficult to guarantee. The use of high-performance tile adhesives can overcome the above difficulties, making the decorative effect of facing tiles more perfect, safe, fast in construction, and material-saving.
The effect of redispersible latex powder on freshly mixed mortar in tile adhesive: prolong working time and adjustment time; improve water retention performance to ensure cement hydration; improve sag resistance (special modified rubber powder); improve workability (easy to apply on substrate, easy to press tiles into adhesive)
The effect of redispersible latex powder on hardened mortar in tile adhesive: it has good adhesion to various substrates, including concrete, plaster, wood, old tiles, PVC; under various climatic conditions, it has great Good deformability.
As the amount of cement increases, the original strength of the tile adhesive increases, and at the same time, the tensile adhesive strength after immersion in water and the tensile adhesive strength after heat aging also increase. With the increase of the amount of redispersible latex powder, the tensile bond strength of the tile adhesive after immersion in water and the tensile bond strength after heat aging increase accordingly, but the tensile bond strength after heat aging increases more obviously.
