Abstract

The invention relates to acrylic acid modified waterproof mortar comprising cement, quartz sands, pulverized fuel ash, triple superphosphate powder, acrylic acid redispersable rubber powder, a water-repellent agent, a deforming agent and other auxiliary agents. The waterproof mortar with compact structure is obtained by adopting the acrylic acid redispersable rubber powder which has excellent ageing-resistant property and water-resistant property and good quartz sand graduation through formulation design and optimization, not only has good waterproof and impervious property, but also has excellent ageing-resistant property and excellent physical property.

Description

technical field [0001] The invention relates to a waterproof mortar material for construction, in particular to a polymer modified waterproof mortar for construction. Background technique [0002] Most of the traditional building waterproof materials are flexible materials, such as various waterproof membranes and waterproof coatings. They form a waterproof isolation layer by paving or coating on the surface of the building base. However, due to the compatibility between the flexible waterproof material and the substrate, its aging resistance is poor, and its cost is high. Waterproof mortar is a kind of cement, sand and gravel as raw materials, mixed with a small amount of admixtures and polymer materials, by adjusting the mix ratio, reducing porosity, increasing the compactness of the interfaces between raw materials, etc. A cement mortar waterproof material with certain impermeability. This kind of waterproof material can be widely used in projects with high structural ...
