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.

Embodiment Construction

[0014] An antibacterial, mildew-proof, and waterproof plugging mortar, made of the following raw materials in parts by weight: ordinary Portland cement 22, river sand 46, attapulgite 14, boiler ash 16, polypropylene fiber 4, palm fiber 2, styrene-acrylic Emulsion 7, water glass 3.5, chitosan 1.4, amyl acetate 8, dimethylethanolamine 2.4, nano iron ferric oxide 1.2, appropriate amount of water.

[0015] The preparation method of described a kind of antibacterial mildewproof waterproof plugging mortar, comprises the following steps:

[0016] (1) Heat amyl acetate to boil under the protection of nitrogen, add nano-ferric oxide to keep the temperature and stir for 1-2 hours, filter, wash and dry, add water glass and chitosan to grind for 20-30 minutes, at minus 15 Freeze at -20°C for 3-5 hours to prepare organically modified nano-ferric oxide;

[0017] (2) Put boiler ash into concentrated hydrochloric acid and disperse ultrasonically at 60-80°C for 1-2 hours, wash until neutral, ...

Abstract

The invention discloses antibacterial mildew-proof waterproof leakage blockage mortar. Nanometer ferriferrous oxide is added and is subjected to organic modification; the surface energy is reduced, so that the surface amphipathicity is realized; by using a three-dimensional protection effect, nanometer particles are uniformly dispersed into the mortar and cannot agglomerate; the pressure-resistant intensity of the product is improved; then, the materials are mutually compounded with polymer styrene acrylic emulsion and polypropylene fiber; through the physical and chemical effects, the surface energy of the polypropylene fiber is improved, so that the bonding force with the mortar is improved; the generation of early-stage micro cracks is well inhibited, so that the seeping resistance performance, the bending resistant intensity and the durability of the product are improved; the boiler ash are modified and are then added into the raw materials to be matched with other effective additives, so that each ingredient o the mortar is uniformly dispersed and cannot easily settle; the waterproof performance of the leakage blockage mortar is obviously improved; the prepared waterproof leakage blockage mortar has the good antibacterial mildew-proof waterproof performance, high seepage resistant stages, high pressure resistant intensity and good anti-aging performance, and has the advantages that the construction is convenient; the cost is low; green and environment protection effects are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antibacterial, mildew-proof, 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 improved, the co...
