Waterborne inorganic slurry interior wall putty and preparation method thereof

Abstract

The invention discloses waterborne inorganic slurry interior wall putty, which is composed of such components as silica sol, styrene acrylic latex, a silicone coupling agent, quartz powder, fillers, an assistant and water. The invention further discloses a preparation method of the waterborne inorganic slurry interior wall putty. The waterborne inorganic slurry interior wall putty has the advantages that the fine particles of the silica sol have strong seepage force on a basement layer, so that the fine particles can seep into the basement layer through capillary tubes and can react with calcium hydroxide in the basement layer of a cement wall to generate calcium silicate so as to provide strong adhesive force to the putty layer; the water resistance and heat resistance are obviously better than those of white latex or acrylic emulsion type organic putty, thereby preventing the film from dropping and saltpetering and prolonging the service life of the wall surface coating engineering, the waterborne inorganic slurry interior wall putty is low in cost, environment-friendly and non-toxic, and is capable of saving the coating cost, thereby having important practical value and environmental protection value.

Description

【Technical field】 [0001] The invention relates to the field of coatings, in particular to a water-based inorganic slurry interior wall putty with silica sol as the main binder and a preparation method thereof. 【Background technique】 [0002] Putty (filling mud) is a kind of decorative material for leveling the surface of the wall, and it is an indispensable product before painting. At present, the interior wall putty used in our country is divided into two categories: ordinary type (Y type) and water-resistant type (N type). Ordinary type (Y type) is mainly made of polyvinyl alcohol construction glue and carboxymethyl cellulose mixed with Shuangfei powder, talcum powder and other powder materials. However, this kind of putty is not water-resistant, and engineering quality problems such as shedding, wrinkling, and peeling often occur after painting. The dry powder type water-resistant putty is made of white cement, hard inorganic cementitious material or gray calcium air-ha...

AI Technical Summary

Problems solved by technology

However, because white cement and gray calcium are easy to cause efflorescence, the latex paint will bloom after being painted, and the condensation speed is fast, which makes the construction inconvenient, and the dry powder putty is very dusty when mixed on site, which affects the health of construction workers.

The paste-like water-resistant putty is made of white latex or acrylic emulsion, which has good comprehensive performance, but is expensive, difficult to polish, and not easy to popularize.
