Abstract

The invention provides quick-drying waterproof plastering mortar and a preparation method thereof. The mortar is prepared from, by weight, 80-120 parts of Portland cement, 60-90 parts of river sand, 40-80 parts of modified mineral powder, 10-15 parts of composite fiber pulp, 2-5 parts of a water reducing agent and 80-150 parts of water, and the modified mineral powder comprises pelelith, water-soluble amino clay, solvent type thermoplastic acrylic resin and an activating agent; the composite fiber pulp comprises glass fibers and a hydrophobic rock wool board; according to the preparation method, the raw materials are reasonably selected and matched, the components are coordinated and matched, the optimized and improved preparation method is matched, and the components in the steps are promoted and matched, so that the prepared plastering mortar is fine and smooth, good in leveling property and high in drying speed, the comprehensive performance is remarkably improved, and the application benefits are obviously improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a quick-drying waterproof plastering mortar and a preparation method thereof. Background technique [0002] Plastering mortar is a general term for a type of mortar that is applied to protect the building base surface by brushing. According to different operations, plastering mortar is divided into on-site mixing mortar and ready-mixed dry powder plastering mortar. Pre-mixed dry powder plastering mortar is a kind of commercial mortar, and dry powder plastering mortar is a mixture of cement, filler, aggregate and various Formulated with functional admixtures. Plastering mortars with different functions apply different wall substrates. For example, there are light-weight walls suitable for aerated concrete blocks, fly ash blocks, and ceramsite bricks, and plastering mortars that are directly scraped on the surface of concrete shear walls. [0003] Quick-drying plastering mortar...
