Problems solved by technology

[0003] Because fair-faced concrete is mostly gray, the color is relatively monotonous, which limits its application occasions. In order to enrich the color of fair-faced concrete and broaden its application scenarios, the prior art mostly adopts the mode of adding pigments in the fair-faced concrete mixing process to realize, but Existing practices, on the one hand, will reduce the color saturation of the fair-faced concrete surface, on the other hand, because the pigment is mixed with the fair-faced concrete, the color graphic design of the fair-faced concrete needs to rely on a specific graphic template, which greatly limits its design style;
[0004] In addition, since fair-faced concrete is a heterogeneous building material, there are many tiny voids inside. The existence of voids makes it easy to absorb water on the one hand, and long-term rain erosion will lead to discoloration and corrosion of fair-faced concrete, affecting the appearance quality On the other hand, the fair-faced concrete can easily absorb dust in the air, making the surface of the fair-faced concrete easily polluted and difficult to clean

Abstract

The invention provides a bare concrete surfactant. The bare concrete surfactant is composed of, by weight percentage, 0.5-0.7% of dispersant, 2-3% of rapid penetrant, 0.3-0.5% of delustering agent, 0.1-03% of defoamer, 25-35% of aqueous emulsion, 3-5% of pH regulator, 0.5-0.8% of flatting agent, 0.2-0.5% of wetting agent, 4.5-7.0% of colorant, 1.0-2.5% of dispersible emulsion powder and 51.7-58.6%of deionized water. The bare concrete surfactant is applied to the surface of bare concrete to maintain the apparent texture of the bear concrete, and meanwhile, to enrich the color system and the design patterns of the bare concrete.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a surface treatment agent for fair-faced concrete. Background technique [0002] Fair-faced concrete is a one-time forming without any decoration. Its natural state formed by the combination of the natural texture of concrete and carefully designed open joints, Zen joints and pull bolt holes is used as a decorative architectural expression. It is widely used in industrial buildings. , Medium and high civil engineering, public buildings and municipal bridges. [0003] Because fair-faced concrete is mostly gray, the color is relatively monotonous, which limits its application occasions. In order to enrich the color of fair-faced concrete and broaden its application scenarios, the prior art mostly adopts the mode of adding pigments in the fair-faced concrete mixing process to realize, but Existing practices, on the one hand, will reduce the color saturation of the fair-f...
