Wetting-free waterproof slurry and preparation method thereof

Abstract

The invention relates to the field of waterproof materials, in particular to a wetting-free waterproof slurry, comprising a liquid agent and a powder agent, wherein the liquid agent comprises a styrene-acrylic emulsion, a VAE emulsion, deionized water, an antifoaming agent, a substrate wetting agent, a leveling agent, a dispersing agent, ethylene glycol, a preservative and a color slurry; the powder agent comprises ordinary Portland cement, quartz sand, metakaolin, water reducer, powder defoamer, zinc stearate, cellulose and powder hydrophobic agent, and the mass ratio of the liquid agent andthe powder agent is 1:1.5-3. The VAE emulsion is adopted for compounding styrene-acrylic emulsion, the base material wetting agent and the leveling agent are added to make the product system get better wetting property. By combining the characteristics of VAE emulsion, the waterproof slurry can be leveled quickly, has good compatibility and excellent adhesion, and can achieve the effect of no wetting on concrete base material, improve the construction efficiency, shorten the construction period and save the cost.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, more specifically, to a non-wetting waterproof slurry and a preparation method thereof. Background technique [0002] Waterproof slurry is a two-component waterproof material specially used for building waterproofing. It is composed of a powder part and a liquid part in a certain proportion. The waterproof slurry used in modern home decoration in waterproof slurry is generally K11 polymer cement-based waterproof slurry. K11 waterproof coating is also called K11 high-grade waterproof material. It is a two-component product consisting of liquid and powder. , a polymer-modified composite waterproof slurry prepared by combining high-molecular polymer emulsion and inorganic powder. The powder is composed of high-quality cement, selected quartz sand and unique high molecular polymer, and at the same time forms an integral whole with double waterproof effect on the base surface.

AI Technical Summary

Problems solved by technology

[0004] However, the K11 general-purpose waterproof slurry currently on the market must first wet the base surface before construction. The construction process is cumbersome. If it is applied on a base surface without wetting or uneven wetting, shrinkage cavities will easily occur, which will seriously affect waterproofing. Effect: In the case of incomplete wetting, due to the high water absorption rate of the base surface, the moisture of the coating film after construction will be absorbed quickly, resulting in poor leveling, uneven coating film, and uneven waterproof effect.

In addition, the K11 general-purpose waterproof slurry also generally has a short opening time. The short construction time makes the construction unable to achieve the best effect, which seriously affects the construction quality.
