Embodiment 1

[0027] A concrete decorative panel has a thickness of 50mm, a length of 1000mm, and a width of 500mm.

[0028] Main concrete raw materials, in parts by mass, are 350 parts of gray Portland cement, 900 parts of ordinary sand, 600 parts of gray fly ash ceramsite, 165 parts of water, and 4 parts of composite thickener; Carry out formwork positioning and manual soft pressing construction process. Among them, KT board is used as the formwork to prepare a tree-shaped figure; when the strength of the main concrete reaches 10MPa or more, the formwork is removed.

[0029] High-bonding polymer mortar is used in the first area of ​​the surface layer. The raw materials are based on parts by mass, 200 parts of white Portland cement, 850 parts of green colored sand, 5 parts of redispersible latex powder, and 140 parts of water; used in the second area of ​​the surface layer Surface layer concrete, raw materials by mass parts, 350 parts of gray Portland cement, 900 parts of gray colored san...

Abstract

The invention relates to a preparation method of a concrete decorative panel, which comprises the following steps: 1) preparing main body concrete, and embedding a template on the surface of the main body concrete for positioning; 2) when the strength of the main body concrete is ≥ 10MPa, removing the template, A concave part is formed at the positioning of the template; 3) The surface layer material is laid in the concave part, polished after hardening, and then sprayed with a transparent color protective agent. Compared with the prior art, the present invention can be applied to decorative panels, outdoor planks, imitation wood components, etc. The concrete decorative panels are simple in preparation process, low in cost, high in mechanical strength, durable and environmentally friendly, and can meet people's needs.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a preparation method of a concrete decorative board. Background technique [0002] As people's quality of life is getting higher and higher, interior decoration has become an indispensable link, but at the same time they will face the problem of household pollution, resulting in the quality of interior decoration not meeting the existing needs. Inorganic material decorative panels will not release gases harmful to human health, and the integrated wall surface can be selected in a variety of colors, durable, green and environmentally friendly, and has broad application prospects. [0003] As the most widely used building material, concrete has attracted more and more attention in the field of decoration due to its high strength, strong plasticity and good durability. Widely used in various garden landscapes. [0004] However, the existing concrete decorative panels are c...
