Problems solved by technology

The main difference between different types of putty powder lies in the different ingredients, resulting in the difference between water resistance and hardness. The general type of putty (Y type) and flexible type (R type) are mainly based on double fly powder (big white powder) and flexible Rubber powder is the main raw material, while the interior wall water-resistant putty is made of cement and flexible rubber powder. Therefore, the interior wall water-resistant putty powder has the advantages of strong adhesion, good water resistance, long service life, and no need to shovel the wall for secondary decoration. However, due to its high strength and poor sanding performance, most water-resistant putties require sanding within 24H, and some even require sanding within 3H, and the sanding is laborious and time-consuming, which seriously restricts the application of this type of putty. The present invention aims to solve the above existing problems

Abstract

The invention relates to an easy-to-polish cement-based interior wall putty, which comprises the following components in parts by weight: 75-90 parts of double fly powder; 10-20 parts of white cement; 0.5-1 part of dispersible organic rubber powder; 0.1~0.5 parts of expansive soil; 1~1.5 parts of cationic polyacrylamide; 0.5~1 parts of carboxymethyl cellulose; 0.1~0.2 parts of silicon dioxide, 0.3~0.5 parts of hydroxypropyl cellulose ether, 1~5 parts of polyvinyl alcohol fine powder; and in the preparation process, carboxymethyl cellulose is first stirred with cationic polyacrylamide, and then hydroxypropyl cellulose ether is added. The beneficial effects achieved by the present invention are: mutual adsorption to form a glue film, prevention of rapid volatilization of water, delay of increase in cement hydration strength, easy grinding and shaping after 72 hours of construction, and meeting the needs of the construction site.

Description

technical field [0001] The invention relates to the technical field of putty, in particular to an easy-to-polish cement-based interior wall putty. Background technique [0002] Putty is a kind of material for filling and leveling the construction surface before the construction of the decorative wall or plate surface. The main purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, so as to obtain a uniform and smooth surface coating. Base. According to JG / T 298-2010 classification of putty for indoor use in construction, interior wall putty is divided into general type putty (Y type), flexible type (R type) and water-resistant type (N type). The main difference between different types of putty powder lies in the different ingredients, resulting in the difference between water resistance and hardness. The general type of putty (Y type) and flexible type (R type) are mainly based on double fly powder (big white po...
