Interior wall putty with mildew-proof function and preparation method thereof

Abstract

The invention discloses interior wall putty with a mildew-proof function and a preparation method thereof. The interior wall putty with the mildew-proof function comprises the components in parts by mass: 2-8 parts of an inorganic cementing material, 0.2-2 parts of an organic additive, 0.1-1 part of cellulose ether, 80-97 parts of heavy calcium carbonate powder, 0.1-0.5 part of a water repellent,1-5 parts of a mildew preventive and 0.5-1 part of a coalescing agent. The water-resistant EVA rubber powder and the coalescing agent act together, so that the water-resistant EVA rubber powder formsa continuous compact film among gaps of heavy calcium carbonate powder particles, invasion of external water vapor is blocked, and the problems of mildew-proof long-term effect and environmental protection property of the interior wall putty are solved.

Description

technical field [0001] The scheme belongs to the field of chemical materials, specifically the application field of building chemical materials. Background technique [0002] Putty is an indispensable layer of fine leveling material for building interior decoration. The market can generally be divided into putty that is mixed with white powder and cooked rubber powder on site and mixed with water, and finished putty that only needs to be mixed with water. The putty prepared on site mainly depends on the experience and preference of the construction master, the quality is unstable, and the strength, water resistance and mildew resistance are extremely poor. At present, putty mildew has become a common problem in interior wall decoration that cannot be ignored. Mildew is an important factor for wall damage. Moldy putty not only seriously affects the appearance of the wall, but also breeds a large number of pathogenic bacteria, and even affects the service life of the house wa...

Problems solved by technology

However, silver ions are easily soluble in liquid. Considering that putty powder needs to be polished during construction, it is inevitable that it will be more or less inhaled by people, causing heavy metal poisoning.

The fourth is to use zinc and its oxides as the anti-mildew technical means, but the stability is not good, and it is easy to be affected by moisture and deteriorate.

But in fact, according to the mechanism of mold production, the more humid the environment, the easier it is for mold to grow. The porous structure of zeolite can just absorb water molecules in the air, and its anti-mildew principle is unscientific.
