Abstract

The invention discloses a preparation method of self-leveling mortar with waterproof and self-cleaning effects. The method comprises the following steps: uniformly mixing modified reinforced fibers and fly ash, adding Portland cement and high-alumina cement, uniformly mixing, heating to 60-65 DEG C, adding other raw materials, and uniformly stirring to obtain the self-leveling mortar. The self-leveling mortar consists of the following components: Portland cement, modified reinforced fibers, fly ash, high-alumina cement, modified redispersible latex, an early strength agent, a defoaming agent,a retarder, a water reducing agent, blast furnace slag and water. According to the self-leveling mortar, the modified reinforced fibers are added and matched with the Portland cement, the high-aluminacement and the modified redispersible latex, so that the compactness of an inorganic system of the cement can be remarkably improved, and the waterproof performance of the self-leveling mortar is remarkably improved; and by adding the modified redispersible latex, the self-cleaning effect of the mortar as a facing layer can be remarkably improved.

Description

Technical field[0001]The present invention relates to the field of self-flowing mortar, and more particularly to a method of preparing a self-leveling mortar having waterproof self-cleaning effects.Background technique[0002]The self-flowing mortar is a dry-shaped powdered material consisting of a plurality of active ingredients. On-site mixing water can be used, and a high planter is deployed, it can obtain a high flat grid, and the early strength is high, and the construction efficiency can be improved. Concrete grounds for flat and all laying materials, widely used in civil and commercial buildings.[0003]At present, my country's self-flowing mortar technology is not completely mature, and it is also facing problems such as poor working performance, low early strength and low waste utilization rate. At present, the self-leveling mortar is basically using the fine river sand to do the collection, but because the river sand mining has caused serious environmental problems, how to red...
