Abstract

The invention relates to the technical field of house building construction, and discloses a gypsum-based lightweight plastering material, which is prepared from the following raw materials in parts by weight: 400 to 600 parts of natural white gypsum powder, 150 to 200 parts of heavy calcium powder, 200 to 400 parts of white sand, 1 to 2 parts of retarder, 1 to 2.5 parts of thickener, 1 to 2 parts of plasticizer, 5 to 10 parts of anti-cracking agent, 0.1 to 0.3 part of air entraining agent and 1 to 3 parts of pigment. The problems that in traditional plastering gypsum, one-time forming delivery cannot be achieved, the bonding strength is insufficient, the color is uneven after forming, the surface is rough, the coating rate is low, and the surface layer strength is insufficient are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a gypsum-based lightweight plastering material and a preparation method thereof. Background technique [0002] At present, wall plastering is mainly divided into leveling layer and scraping white layer. The leveling layer mainly uses cement-based plastering mortar and whitewashing stone, and the scraping white layer mainly uses various kinds of putty. The leveling layer generally has problems such as rough walls, large wall color differences, hollowing and cracking, and subsequent repairs are difficult and cumbersome. The problem of powder removal mainly occurs due to insufficient strength when scraping the white layer. The overall construction process of the existing plastering is complicated, the cost is high, and the follow-up quality is difficult to maintain. [0003] Therefore, how to provide a plastering gypsum with simple construction and excellent quality...
