Abstract

The invention relates to the technical field of building materials, and specifically discloses a gypsum-based plastering mortar and a preparation method thereof. The gypsum-based plastering mortar includes the following components in parts by mass: 16.4%-19.5% of gypsum, 5.9%-7.8% of cement, Sand 71.5%-76.1%, additive 1.3%-1.7%; the sand is one or more of river sand, mountain sand, slag or industrial waste slag, and the gypsum is desulfurization gypsum, phosphogypsum, electric gypsum, One or more of titanium gypsum or fluorogypsum, the additive includes an emulsion and a stabilizer, and the mass ratio of the emulsion to the stabilizer is 4‑6:1. The gypsum-based plastering mortar of the present invention realizes the recycling of waste gypsum. The product has the advantages of less material usage per unit area and low volume specific gravity of the material; the product is a flexible material with suitable hardness and is not easy to crack; the bonding strength is high and the wall is the most convex The exposed parts can be covered with 3‑5mm mortar.

Description

technical field [0001] The invention relates to the technical field of building materials, and specifically discloses a gypsum-based plastering mortar and a preparation method thereof. Background technique [0002] Mortar, also known as mortar, is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. According to the different main components, it can usually be divided into cement mortar, lime mortar, and cement-lime mixed mortar. According to the use of mortar, it is mainly divided into masonry mortar and plastering mortar. Plastering mortar is used for plastering surfaces such as walls, floors, roofs and beam-column structures for the purpose of protection and decoration. The disadvantages of the existing cement mortar are that the volume specific gravity of the material is large, the amount of material used per unit area is large, and the bonding strength is poor, resulting in a thick plastering layer.
