Slow-seepage-resistant waterproof plugging mortar and preparation method thereof

Abstract

The invention discloses slow-seepage-resistant waterproof leaking stoppage mortar and a preparation method thereof. The formula and the manufacturing process of the mortar are reasonable in design and convenient to use; cement, sand and mineral admixtures serve as composite gel components, and a water-borne epoxy resin emulsion and a water-borne epoxy curing agent can adjust the setting time of the mortar, so the strength, anti-permeability and other properties of the mortar are improved, and the mortar has good waterproof and anti-permeability properties; and in addition, a super absorbent polymer is wrapped by a water-soluble polymer to form a microcapsule, the super absorbent polymer does not participate in a reaction during stirring, mixing and cement solidification in virtue of the characteristic of slow dissolution of the water-soluble polymer, but the surface of the microcapsule is dissolved when mortar cracks and water flows into the microcapsule, so the water-absorbent polymer can quickly block cracks by utilizing the water absorption expansibility of the water-absorbent polymer, and a certain leakage self-repairing function is obtained.

Description

technical field [0001] The invention relates to the technical field of waterproof building materials, in particular to an anti-slow seepage waterproof plugging mortar and a preparation method thereof. Background technique [0002] With the advancement and development of grassroots construction and urbanization, the demand for plastering mortar used in building decoration projects is also increasing. Plastering mortar is a type of plastering mortar used to level or protect the base surface of the building Mortar, collectively referred to as mortar, is suitable for decoration of interior and exterior walls, cover surfaces, bottom surfaces, ceiling plastering, etc. of construction and decoration projects, and plays a protective and beautifying role. [0003] At present, plastering mortar generally does not have the performance of heat resistance and fire prevention. When a fire breaks out in a building, the temperature of the wall surface will change due to the fire. When the ...

Problems solved by technology

[0003] At present, plastering mortar generally does not have the performance of heat resistance and fire prevention. When a fire breaks out in a building, the temperature of the wall surface will change due to the fire. When the base concrete (or mortar) cracks, it will pull the paint to make it break, resulting in leakage of the building and failure of waterproofing. Buildings with brick-concrete or concrete structures, Due to structural deformation, hydration shrinkage of concrete (mortar), and thermal expansion and contraction, many cracks will occur.

This is a common problem in construction at present. Although scholars have made great efforts in various aspects, due to construction, maintenance and human factors, cracks in mortar and concrete are still inevitable.
