Abstract

The invention discloses attapulgite interior wall putty powder and a preparation method thereof. The attapulgite interior wall putty powder is prepared from the following raw materials in parts by weight: 15-28 parts of attapulgite clay, 10-18 parts of white cement, 5-10 parts of calcium oxide, 18-25 parts of anhydrous calcium sulfate, 1-5 parts of polyacrylamide, 0.6-3 parts of hydroxypropylmethyl cellulose, 2-5 parts of fly ash and 0.2-0.5 part of pure iron powder. By adopting the attapulgite clay with high variable area and strong adsorption and combining with the calcium oxide, the anhydrous calcium sulfate, the polyacrylamide and the fly ash, the attapulgite interior wall putty powder is environmentally friendly and pure white, is strong in adhesive power, resists acid and base corrosion and is stable in storage; and in addition, by adding the pure iron powder, the thermal expansion and cold contraction coefficient of the putty powder is much lowered, the putty powder cannot chap because of large temperature difference variation, the weatherability is improved, and indoor harmful electromagnetic radiation can also be absorbed.

Description

technical field [0001] The invention relates to the field of decorative interior wall building materials, in particular to an attapulgite interior wall putty powder and a preparation method thereof. Background technique [0002] Putty powder is a kind of building decoration material, the main components are talcum powder and glue. I just bought a layer of white putty on the surface of the blank room. Usually the whiteness of the putty is above 90 degrees and the fineness is above 330 degrees. Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for internal use. Putty is generally composed of base material, filler, water and additives. Base material, als...
