Abstract

The invention belongs to the technical field of building coating and provides novel bottom-layer gypsum plaster and an application method thereof. The novel bottom-layer gypsum plaster is prepared from the following components in parts by mass: 135 to 170 parts of gypsum, 700 to 810 parts of quartz sand, 55 to 66 parts of caking coal ash, 1.3 to 1.6 parts of a retarder, 1.4 to 1.6 parts of methylcellulose, 45 to 55 parts of cement, 2.7 to 3.2 parts of dibutyl phthalate, 4 to 6.2 parts of VAE (Vinyl Acetate Ethylene) emulsion; the substitution degree of the methyl cellulose is 1.6 to 2.0. By adopting the technical scheme, the problem in the prior art that the bonding strength and the like of the gypsum plaster cannot meet requirements is solved.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and relates to a primer plaster and a using method thereof. Background technique [0002] In recent years, the leveling requirements for building interior decoration, appearance requirements and environmental protection requirements have become higher and higher, so the interior decoration materials are required to have harmless and environmental protection characteristics, and plaster plaster is an inorganic material, non-toxic, harmless, fireproof and environmentally friendly. Plastering of various walls and ceilings in buildings. Contents of the invention [0003] The invention proposes a bottom plaster plaster and its use method, which solves the problem that the bond strength of the plaster plaster in the prior art cannot meet the demand. [0004] Technical scheme of the present invention is realized like this: [0005] A kind of base plaster and its application method: ...
