Problems solved by technology

[0005] Wall cracking is a problem often encountered in construction projects. Most of the building walls will have cracks to varying degrees. The traditional waterproof mortar has high strength and poor flexibility, and cannot resist slight deformation and cracking of the wall, resulting in waterproof layer useless
In addition, traditional waterproof mortar is usually made of cement, sand, modifiers, etc. It has a very heavy weight and a single function, which causes a lot of load-bearing pressure on the wall or insulation layer, burying hidden dangers to building safety.
[0006] The existing technology has the following defects: (1) the waterproof mortar is heavy, which increases the safety hazard of the wall; (2) the setting time is long; (3) the impermeability is poor; (4) the compressive and flexural strength is weak; (4) The bonding strength between the waterproof mortar and the base layer is poor; (5) Improve the shrinkage and cracking of the waterproof mortar

Abstract

The invention provides energy-saving and light quick-setting waterproof mortar for an outer wall. The waterproof mortar is prepared from liquid materials and powder materials. The weight ratio of the liquid materials to the powder materials is 1:2.77-1:3.33. The liquid materials include styrene-butadiene latex, cellulose ether, water, a defoaming agent and a preservative. The powder materials include portland cement, hollow glass beads, coal ash, quartz sand, a cement expansion agent, a water reducing agent, a dispersing agent, a setting accelerator and a thixotropic agent. The waterproof mortar is short in setting time, the initial setting time is 45-70 min, and the final setting time is 1.50-2.50 h; besides, the waterproof mortar is strong in seepage resistance and good in compressive strength and flexural strength.

Description

technical field [0001] The invention relates to a waterproof mortar, in particular to a quick-setting energy-saving lightweight waterproof mortar for exterior walls, which belongs to the field of building waterproof coatings. Background technique [0002] With the development of the economy, environmental pollution and energy crisis have become increasingly prominent, and people have higher and higher requirements for building quality and lifespan, especially the leakage of building exterior walls, which has always troubled people. [0003] Once the exterior wall leaks, it will directly affect the interior wall, and the insulation layer of the exterior wall will also hollow out and fall off under water immersion, directly threatening people's lives. How to reduce or eliminate external wall leakage is an urgent problem to be solved in the construction industry. [0004] There are two schemes for the waterproofing of the exterior wall: 1. Take waterproof measures outside the ...
