Imitated bare concrete integrating primer paint and middle coating and preparation method thereof

Abstract

The invention relates to imitated bare concrete integrating primer paint and middle coating and a preparation method thereof, and belongs to the technical field of building decoration paints. The imitated bare concrete is prepared from the following components in percentage by mass: 15 to 30 percent of pure acrylic emulsion, 5 to 18 percent of silicon resin emulsion, 0.1 to 1 percent of cellulose,0.1 to 1 percent of wetting agents, 0.1 to 0.5 percent of anti-foaming agents, 0.5 to 1.5 percent of waterproof agents, 1 to 8 percent of titanium dioxide, 1 to 15 percent of talcum powder, 1 to 15 percent of mica powder, 15 to 30 percent of heavy calcium carbonate, 0.5 to 1.5 percent of propanediol, 0.1 to 0.5 percent of preservatives, 0.1 to 1 percent of thickening agents and water for supplementing the total percentage to 100 percent. The imitated bare concrete involved in the invention has the advantages that the sealing effect of the primer paint and the coloring effect of the middle coating in the bare concrete are integrated, so that the construction process is simplified; the effect and function close to bare concrete are reached; the manufacturing cost is low; the construction isconvenient; and the construction efficiency is improved.

Description

technical field [0001] The invention relates to an imitation fair-faced concrete in which a primer and an intermediate coating are integrated, and belongs to the technical field of architectural decorative coatings. Background technique [0002] Fair-faced concrete, also known as decorative concrete, is named for its great decorative effect. By directly using the natural surface effect of cast-in-place concrete as the decorative surface, it is different from ordinary concrete. It has a smooth surface, uniform color, no defects and pollution, and usually Apply one or two layers of transparent protective agent on its surface to make it more natural and dignified. [0003] At present, domestic clear-faced concrete is still in the development stage, which belongs to the emerging construction technology, and there are not many units that really master the design and construction of this type of building. Clear-water concrete includes three parts: primer, intermediate coat and to...

AI Technical Summary

Problems solved by technology

During the construction of fair-faced concrete, the primer and the mid-coat need to be applied twice separately. The primer is applied first, and then the mid-coat. Both cannot achieve the sealing effect of the primer and the coloring effect of the primer

The final wall decoration effect of fair-faced concrete also depends on the quality of concrete pouring and the later transparent protective spraying construction. The construction process is complex and there are many construction difficulties, so concrete is a great challenge to building construction
