Abstract

The invention discloses flexible waterproof mortar and a production method thereof. The method comprises a liquid material component and a powder material component. The liquid material component comprises styrene-acrylic emulsion, acetic acid emulsion, water, a defoaming agent, and a bactericide. The powder material component comprises quartz powder, wollastonite powder, ash concrete, a water-reducing agent, a dispersing agent, and a leveling thixotropic agent. The waterproof mortar is prepared from the liquid material and the powder material according to a ratio of 1:2. The waterproof mortar has good extensibility and high elasticity. With the mortar, slight cracks on a base layer can be resisted. During vertical surface construction, the waterproof mortar is prevented from flowing and dropping, and has good construction performance. After coating, the mortar surface is smooth as mirror. The mortar is suitable for underground space water prevention, seepage prevention, and moisture prevention. The mortar is especially suitable for water prevention of buildings with waterproof exposed underground. Soaking of underground condensed water and dew condensation to the building can be effectively resisted for a long time.

Description

technical field [0001] The present invention relates to a kind of building waterproof paint, specifically to a kind of flexible waterproof mortar and its [0002] production method. Background technique [0003] With the rapid development of the construction industry, the requirements for building waterproof materials are also increasing, and waterproof mortar is widely used as an excellent waterproof material. The emulsion used in the existing waterproof mortar is a rigid emulsion, and the sand used in the powder is also relatively thick and has a rough surface. Moreover, the existing mortar is rigid and has little elasticity, [0004] It is easy to be brittle and not suitable for the base surface with large amount of activity. [0005] In order to solve the above problems, flexible waterproof mortars have appeared on the market. Flexible waterproof mortars use elastic emulsions, which not only ensure their strength, but also have a certain degree of flexibility, and ca...
