Preparation method of multi-tone pattern transfer concrete

Abstract

The invention discloses a preparation method of multi-tone pattern transfer concrete. According to the technical scheme, sand is classified according to different particle size ranges, and one particle size range corresponds to one color; a retarder is transferred to a base membrane according to the design pattern, wherein the concentration of the retarder in the transferred pattern changes according to the depth needing to be retarded; the prepared sand is used as fine aggregate to be mixed into colored aggregate mortar, and the colored aggregate mortar is poured on the surface of the transferred membrane; the colored aggregate mortar is fully vibrated so as to realize internal layering; after the colored aggregate mortar is initially set, a layer of common mortar is poured on the color aggregate mortar; curing is carried out for a period of time to obtain a hardened concrete base body; the base membrane is torn off from the concrete base body; and a high-pressure water gun is used for flushing the surface of the concrete base body with the base membrane torn off, so that partial aggregate is exposed to obtain the pattern. The method is simple in process, low in operation difficulty and high in pattern precision degree.

Description

technical field [0001] The invention relates to the field of concrete decoration, in particular to a method for preparing multi-tone pattern transfer concrete. Background technique [0002] Transfer concrete is a kind of decorative concrete that exposes the aggregate of the patterned part of the concrete surface through retarding technology to form a pattern. It is characterized in that the patterns are fine and complex, and can be changed at will. Compared with ordinary decorative materials, transfer concrete can give architects great creative space and achieve excellent artistic effects. Therefore, the development of transfer concrete is getting faster and faster, and the scope of application is getting wider and wider. [0003] The production method of transfer-printed concrete is to print the retarder on the base film according to a certain pattern, pour concrete on the base film, uncover the base film after the concrete hardens, and wash the concrete surface with water...

Problems solved by technology

This patent application provides a method for color transfer pattern cement products, but there are still the following problems: (1) The process is complicated: it is necessary to separately prepare transfer printing inks of different colors and print them in different areas, and separately prepare different colors of cement mixtures for layered pouring , with many process steps and high level of process operation; (2) The surface color is easy to spread, because the transfer ink has different colors, and it is easy to spread between each other, resulting in unclear color boundaries on the surface of the product and low pattern fineness; (3) During the layered pouring of the cement mixture and the static hardening process, affected by gravity, the particles (such as sand) will form natural layers, and the fine sand will sink, which will easily cause the colors of each layer to mix, affecting the correct presentation of the final color pattern of the product, and the pattern is fine. low level
