Problems solved by technology

Ordinary putty generally needs to add harmful substances such as white glue, cooked rubber powder, cellulose, etc., which has poor environmental protection performance and is very harmful to the construction workers and owners; and after ordinary putty is reconciled and constructed, its strength is far lower than that of flexible water-resistant putty during grinding. , so it is less labor-intensive when polishing, but it is also easy to differentiate, peel, and crack; if you want to replace the paint, you can only eradicate the putty and old paint, and re-coat it

Abstract

The invention discloses environment-friendly flexible interior wall putty and a preparation method thereof. The environment-friendly flexible interior wall putty comprises the following components by mass percent: 20-26% of water, 20-27% of acrylic emulsion, 5-10% of heavy calcium carbonate powder, 10-15% of light calcium carbonate powder, 12-19% of talcum powder, 5-7% of blanc fixe, 5-8% of bentonite, 2-3.7% of hydroxyethyl methyl cellulose ether, 1-3% of an antifreezing agent, 0.1-0.3% of a defoamer and 0.1-0.3% of a dispersant. The interior wall putty disclosed by the invention has the advantages of good flexibility, strong waterproofness, good crack resistance, fine and smooth surface texture after being scraped and the like, and is environment-friendly and not easy to atomize.

Description

Technical field [0001] The invention belongs to the field of building interior wall decoration, and relates to a wall putty, in particular to an environmentally friendly flexible interior wall putty and a preparation method thereof. Background technique [0002] In building interior wall decoration, the quality of putty directly affects the decorative effect of interior wall painting. Putty is a decorative material for smoothing the surface of the wall. It is an indispensable product before painting to remove the uneven defects on the surface of the coated object. Ordinary putty generally needs to add large white glue, cooked rubber powder, cellulose and other harmful substances, which have poor environmental protection performance and are very harmful to the constructors and owners; and after the construction of the ordinary putty, the strength is much lower than that of the flexible water-resistant putty. Therefore, it is more labor-saving when polishing, but it is also easy t...
