Problems solved by technology

Due to the large gap between the level of domestic concrete pouring molding technology and foreign countries, the natural appearance of once-molded concrete is mostly not decorative, and common defects such as cold joints, pan-alkali, rust spots, pockmarks, honeycomb, etc., are difficult to achieve fair-faced concrete in technology High standard requirements for molding

Abstract

The invention discloses an as-cast finish concrete simulated coating. The coating consists of a bottom coating, a middle coating and a surface coating, wherein the bottom coating is an organic silicon polymer; the middle coating is a composition consisting of self-crosslinked polymer, filler, pigment, other auxiliary agents and water; the surface coating is a fluorine silicon resin polymer; the bottom coating is a closing layer and can play a role in closing pores of a base material; the middle coating is a coloring layer and can play a role in approaching the effect of the required as-cast finish concrete; and the surface coating is a cover surface layer and plays a role in resisting weather and contamination. The coating breaks through the technical bottleneck of as-cast finish concrete at home, and radically reduces the construction cost of the as-cast finish concrete.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a paint imitating fair-faced concrete. Background technique [0002] Fair-faced concrete, also known as decorative concrete, gets its name because of its great decorative effect. It belongs to one-time pouring molding, without any external decoration, and directly uses the natural surface effect of cast-in-place concrete as the finish. Therefore, it is different from ordinary concrete. One or two layers of transparent protective agent looks very natural and dignified. [0003] However, the technology and process of "clear-faced concrete" have undergone major changes since it entered China. Due to the large gap between the level of domestic concrete pouring molding technology and foreign countries, the natural appearance of once-molded concrete is mostly not decorative, and common defects such as cold joints, pan-alkali, rust spots, pockmarks, honeycomb, etc., a...
