The mortar comprises the following parts by weight: 80-120 parts of Portland cement, 60-90 parts of river sand, and 40-80 parts of modified ore powder , 10-15 parts of composite fiber pulp, 2-5 parts of water reducing agent, 80-150 parts of water, modified ore powder including volcanic stone, water-soluble amino clay, solvent-based thermoplastic acrylic resin, activator; composite fiber pulp including glass Fiber and hydrophobic rock wool board; in this application, through the rational selection of raw materials, the cooperation and compatibility of components, and the optimized and improved preparation method, the components promote the coordination between steps, and the obtained plastering mortar has good leveling performance and drying speed. block, and the comprehensive performance is significantly improved, and the application benefit is significantly 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 provide protection on building base surfaces. According to different operations, plastering mortar is divided into on-site mixing mortar and pre-mixed dry powder plastering mortar. Pre-mixed dry powder plastering mortar is one of the commercial mortars. Among them, dry powder plastering mortar is a combination of cement, filler, aggregate and various It is formulated with functional admixtures. Plastering mortars with different functions apply different wall substrates. For example, there are lightweight walls suitable for aerated concrete blocks, fly ash blocks, ceramsite bricks, etc., and plastering mortar that is directly scraped on the surface of the concrete shear wall. [0003] Quick-dryin...
