Abstract

The invention discloses a formula of putty for an inner wall of a building. The formula includes desulfurized gypsum, quartz powder, a modifier, an inorganic gel, a retarder, an anti-cracking agent, and redispersible gelatine powder. The modifier is hydroxypropyl methyl cellulose, the inorganic gel is sodium bentonite, the retarder is polyphosphate, the anti-cracking agent is lignocellulose, and the redispersible gelatine powder is polyvinyl acetate or ethenoid resin. The putty for the inner wall of the building has favorable water resistance and bonding strength and convenient construction, as well as no hollowness, cracking and duslting on a scraped basal plane; and meanwhile, the scraped putty layer has compact structure, ventilation maintaining and natural film forming, therefore, the wall surface is smoother, and the consumption of emulsion paint is saved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a formula for building interior wall putty. Background technique [0002] At present, building interior wall putty generally uses old powder, white cement, gray calcium powder or talcum powder, lithopone, etc. as the base material, and is mixed with formaldehyde adhesive on site. There are deficiencies such as poor water resistance, poor bonding strength, irritating dust, and yellowing of old walls. Chinese patent literature discloses some methods for preparing putty, as the Chinese invention patent of CN101037557 on September 19, 2007 disclosed the preparation method of desulfurized gypsum preparation dry powder batch wall putty as the notification number, and the Chinese invention patent of CN1454945 was issued in 2003 Environmentally friendly gypsum-based building putty powder was disclosed on November 12, and the Chinese invention patent of CN101423679...
