Problems solved by technology

Most of the construction units only use the plastering mortar used for the wall to strengthen the treatment of this part, but so far, most of the external thermal insulation systems that use fire protection belts have protrusions, depressions, cracks, and water seepage in this part. The most important reason for these problems is still the local reinforcement parts deal with mortar and improper construction technology

Abstract

The invention discloses a flexible waterproof mortar, a preparation method and applications thereof, wherein the flexible waterproof mortar is formed by compounding a component A and a component B according to a mass ratio of 1:2-4, the component A comprises water, a water reducing agent, a preservative, a defoaming agent and an emulsion according to a mass ratio of 50-80:0.3-0.8:0.1-0.2:0.1-0.3:20-50, and the component B comprises cement, a filler, cellulose ether, a thixotropic lubricant and a water repellent according to a mass ratio of 20-40:60-80:0.1-0.4:0.5-1:0.1-0.3. According to the present invention, the preparation method is simple and easy to perform; the obtained product has advantages of good flexibility, good water resistance, moderate viscosity, excellent thixotropy and excellent water retention property, wherein the surface is delicate and compact and does not produce cracking, water seepage, blistering and local projection after the construction of the flexible waterproof mortar, such that the construction performance and the decoration effect of the flexible waterproof mortar are improved.

Description

technical field [0001] The invention relates to a building material, in particular to a flexible waterproof mortar and its preparation method and application. Background technique [0002] EPS decorative line is a kind of building exterior wall decoration material emerging in my country in recent years. It uses flame-retardant B1 grade polystyrene foam board automatically cut into various shapes by computer as the core material, and is passed through the external auxiliary grid cloth. It is made by coating polymer mortar and other materials, and is a decorative component used for building facade modeling. At present, when this product is applied to building walls, most of the common external insulation plastering mortar or putty is used for joint treatment. Therefore, the most frequent problem is the joint between EPS decorative lines or the joint between EPS decorative lines and The joints between the walls are cracked, water seeped, and bulged, and the joints usually look ...
