Abstract

The invention relates to energy-saving leveling putty powder, which is characterized by being prepared from the following raw materials in percentage by weight: 20 to 30 percent of white cement, 5 to 10 percent of gray calcium powder, 40 to 60 percent of heavy calcium carbonate powder, 5 to 15 percent of 50 to 100-mesh light sand, 0.1 to 1 percent of reinforcing fiber, 0.1 to 1.5 percent of polyvinyl alcohol, 0.1 to 1.8 percent of cellulose and 1 to 3 percent of polymer powder, wherein the light sand is polyphenyl particles, vitrified micro bubbles or expanded perlite; the reinforcing fiber is 2-mm polypropylene fiber; and the cellulose is carboxymethyl cellulose. The energy-saving leveling putty powder has the characteristics of high strength, high water resistance, no toxicity or odor, yellowing resistance and the like; moreover, by adding the light sand with heat preservation and thermal insulation function, the putty powder has the obvious characteristics of light weight, heat preservation, high thermal insulation, abrasion resistance, corrosion resistance, high electric insulating performance, radiation protection and the like, while the basic performance is ensured.

Description

Technical field: [0001] The invention belongs to the field of building materials, in particular to an energy-saving leveling putty powder used for priming interior and exterior walls. Background technique: [0002] At present, there are many materials used for interior and exterior walls in the construction industry. Traditionally, gypsum, talcum powder, lime paste, and white cement are infiltrated with 107 glue, and stirred into a paste for construction and scraping. As people pay more attention to environmental protection, especially interior walls In terms of primer, 107 glue has been abandoned, and most of them use putty powder to adjust water for primer. The putty powder is mainly processed from heavy calcium carbonate, white cement and other materials. After the primer is cured, the hardness is moderate and it is convenient for sand leveling. The main indicators of the existing putty powder are crack resistance, no peeling, no shedding, and certain hardness and water ...
