Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail through specific examples below, and the shown examples are only exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0039] Referring to table 1, the formula composition comprising embodiment 1-embodiment 5:

[0040] Table 1

[0041]

[0042]

[0043] The mass percentage range of A component in Table 1 is: 60-72%; The mass percentage range of B component is 28-45%; The mass percentage range of color paste is: 0.1-0.4%; A component, B component, The sum of the mass percentages of color paste is 100%.

[0044] Among them: A component: inorganic bonding material such as: industrial grade 400 mesh calcium hydroxide, purity ≥ 90%; filler is 325 mesh -20 mesh graded white heavy calcium stone powder and river sand. Cellulose ether is HPMC-40US (average viscosity 40000cps, 2% solution / 20°C).

Abstract

The invention provides an as-cast concrete and a preparation method thereof. The as-cast concrete paint is in the form of an organic-inorganic combination product and the calcium hydroxide is added into the paint. Due to the adoption of calcium hydroxide, the paint is endowed with the mottled, dignified and natural effect that none of texture paints possesses, while calcium hydroxide serves as one part of a resin emulsion polymerization network. In this way, the strength of the polymer reticular structure is improved. Therefore, the as-cast concrete paint has the advantages of both normal concretes and texture paints. That is, not only the as-cast concrete paint has the uniquely natural, dignified and unadorned appearance of the as-cast concrete, but also the as-cast concrete paint has the characteristics of paints at the same time, such as easy colour modulation and easy construction.

Description

technical field [0001] The invention relates to an imitation fair-faced concrete and a preparation method thereof, in particular to an organic-inorganic composite imitation fair-faced concrete and a preparation method thereof. Background technique [0002] Fair-faced concrete is also called decorative concrete; it gets its name because of its great decorative effect. It belongs to one-time pouring molding, without any external decoration, and directly adopts the natural surface effect of cast-in-place concrete as the finish, so it is different from ordinary concrete, with smooth surface, uniform color, sharp edges and corners, no damage and pollution, and looks very natural ,solemn. [0003] Fair-faced concrete was produced in the 1920s. As concrete was widely used in the construction field, architects gradually shifted their attention from concrete as a structural material to the texture of the material itself, and began to use the inherent decorative features of concrete ...
