Abstract

The invention relates to the technical field of building materials, and particularly discloses gypsum-based plastering mortar and a preparation method thereof. The gypsum-based plastering mortar comprises the following components in parts by weight: 16.4% to 19.5% of gypsum, 5.9% to 7.8% of cement, 71.5% to 76.1% of sand and 1.3% to 1.7% of additive, wherein the sand is one or a multiple mixture of river sand, mountain sand, furnace slag and industrial mineral waste residues; the gypsum is one or a multiple mixture of desulphurization gypsum, phosphorus gypsum, electric gypsum, titanium gypsum and fluorine gypsum; and the additive comprises an emulsion and a stabilizer in a mass ratio of (4-6) to 1. The gypsum-based plastering mortar realizes the recycling of the waste gypsum, has the advantages of small usage amount of materials in unit area, low material volume ratio, flexibility, moderate hardness, small possibility of cracking, high bonding strength and the like, and ensures that the most convex position of a wall body can be shield by only utilizing the mortar of 3mm to 5mm.

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.
