Novel energy-saving high anti-permeability waterproof anti-leakage mortar and manufacturing method thereof

Abstract

The invention discloses novel energy-saving high anti-permeability waterproof anti-leakage mortar. Nano calcium carbonate is added and organically modified, the surface energy is lowered, the surface amphipathy is achieved, so that the three-dimensional protective effect is used for evenly dispersing nano-particles into mortar, agglomeration is easily caused, the product compressive strength is improved, then, the mortar is compounded with polymer styrene-acrylic emulsion and polypropylene fiber, the surface energy of the polypropylene fiber is improved on the physical and chemical effects, the binding power between the mortar and the popypropylene fiber is further improved, early-stage micro-cracks are restrained from being generated, and the anti-permeability, the breaking strength and durability are improved; coal residues of a thermal power plant are modified and added into raw materials and then compatible with other effective additives, the components of the mortar are dispersed uniformly, sedimentation is easily caused, the waterproof performance of leakage mortar is obviously improved, and the obtained waterproof anti-leakage mortar has the advantages of being low in environmental load and environmentally friendly, saving energy, being low in cost and long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel energy-saving, high-impermeability, and waterproof plugging mortar and a manufacturing method thereof. Background technique [0002] Leakage of buildings is a common problem in the quality of buildings. The reason is that the concrete structure of construction engineering cracks due to self-shrinkage, temperature difference deformation, design defects or construction, etc., resulting in leakage, which leads to roof leakage and wall leakage. 1. The phenomenon of peeling off of the plaster layer not only disturbs people's normal life and work, but also directly affects the service life of the whole building, so waterproof plugging mortar emerges at the historic moment. Waterproof plugging mortar uses high-quality cement, sand, and stone as raw materials, and is mixed with various polymer additives. By adjusting the mix ratio, the cement pore structure can be impr...

Problems solved by technology

However, the compressive strength of the cement mortar obtained by the treatment method in this paper is low, and it needs to be modified

[0005] Nanomaterials have surface effects, small size effects, quantum size effects, and macroscopic particle tunneling effects. These special properties make them irreplaceable materials in polymer modification and improved coating and adhesive properties. The present invention uses nanomaterials to The styrene-acrylic emulsion is modified and added to the raw materials to improve the product's compressive strength, water resistance, anti-corrosion and aging resistance. However, these special properties of nanomaterials also have certain limitations. For example, due to the small size ratio The surface energy is large and easy to agglomerate, resulting in uneven dispersion. Therefore, it is necessary to modify the added nanomaterials and then add them to the raw materials to improve the technical indicators of the product.
