However, the existing concrete decorative plate has complex preparation process, higher cost, insufficient mechanical strength and limited application.
Disclosure of Invention
The invention aims to provide a preparation method of a concrete decorative plate, which can be suitable for decorative plates, outdoor trestles, wood-like members and the like, and the concrete decorative plate has the advantages of simple preparation process, low cost, high mechanical strength, durability, environmental friendliness and capability of meeting the requirements of people.
The purpose of the invention can be realized by the following technical scheme:
a preparation method of a concrete decorative plate comprises the following steps:
1) preparing main concrete, and embedding a template on the surface (optional local surface) of the main concrete for positioning (capable of assisting a manual soft-pressing construction process);
2) when the strength of the main body concrete is more than or equal to 10MPa, removing the template, and forming a concave part at the positioning position of the template;
3) and paving the surface layer material in the concave part, polishing after hardening, and spraying a transparent color protective agent.
Further, the main concrete comprises the following components in parts by weight: 400 parts of cement 350-containing materials, 1000 parts of sand 900-containing materials, 600 parts of fly ash ceramsite 500-containing materials, 170 parts of water 150-containing materials and 2-4 parts of composite thickening agents.
Further, the surface layer material comprises one or two of surface layer concrete or high-bonding polymer mortar.
Further, the surface concrete comprises the following components in parts by weight: 400 parts of cement 350-containing materials, 1000 parts of color sand 900-containing materials, 600 parts of fly ash ceramsite 500-containing materials, 170 parts of water 150-containing materials and 2-4 parts of composite thickening agents; the high-adhesion polymer mortar comprises the following components in parts by weight: 200 parts of cement, 850 parts of colored sand, 5-10 parts of redispersible latex powder and 150 parts of water. The high-bonding polymer mortar can be firmly bonded with the main concrete, and can be combined with a template to realize the color treatment of the surface.
Further, the cement is portland cement, the composite thickening agent is a commercially available composite thickening agent, and the redispersible latex powder is a commercially available redispersible latex powder. The Portland cement is preferably white Portland cement or gray Portland cement, and red, yellow, blue, green or brown colored Portland cement can also be selected. The composite thickener generally contains various components such as a water reducing agent, a polymer tackifier, a retarder, a water retaining agent, a defoaming agent, wood fiber and the like, and the components can be adjusted by matching with a process according to actual production. The setting time is prolonged by adjusting the composite thickening agent, and the ceramsite concrete mixture is adjusted to a better workability state by combining the adjustment of water consumption.
Furthermore, the fineness modulus of the colored sand is 2.3-3.0.
Further, the fly ash ceramsite comprises the following components in parts by weight: 20-60 parts of fly ash, 28-60 parts of yellow river sand, 10-15 parts of waste FCC catalyst, 0-3 parts of broken rock wool powder and 0-3 parts of metal oxide, wherein the fly ash ceramsite is formed by mixing and firing all the components. The yellow river sand and the waste FCC catalyst are added in the molding process of the fly ash ceramsite, so that the calcining melting point can be obviously reduced, the glaze forming performance is good, and the water absorption rate is low. Due to the addition of the metal oxide, the fly ash ceramsite with different colors can be fired according to different requirements by selecting the metal oxides with different colors (such as copper oxide, iron oxide and the like), for example, the fly ash ceramsite with gray, yellow, red and the like can be prepared.
Furthermore, the particle size of the fly ash ceramsite is 5-15mm, the cylinder pressure strength is more than or equal to 10MPa, and the water absorption rate is less than 2%. The lower the water absorption of the fly ash ceramsite is, the more the mortar can not be soaked into the ceramsite, and the color of the fly ash ceramsite can be displayed when the surface treatment is carried out.
Further, the dry weight of the main body concrete and the surface layer concrete is 1950-2100kg/m3The compressive strength is more than or equal to 30 MPa.
Further, the transparent color protective agent comprises one of epoxy resin finish paint, acrylic finish paint or polyurethane finish paint. The transparent color protective agent plays the roles of color preservation, no fading and carbonization prevention of the prefabricated decorative plate, and can also increase the wear resistance of the decorative plate. The transparent color protectant is selected from commercially available transparent color protectants.
When the concrete decorative plate is prepared, the main concrete (namely the bottom layer) is firstly prepared, and then the surface layer concrete with a certain color and/or the high-adhesion polymer mortar are paved on the main concrete to prepare the surface layer with a certain color and shape. The method comprises the steps of selecting a template with a proper shape according to requirements, placing the template on main body concrete for template positioning, taking out the template when the main body concrete reaches a certain strength, sinking the main body concrete into a certain shape at the moment, enabling the sunk part to be lower than the surface of the main body concrete, paving surface layer concrete and/or high-adhesive polymer mortar on the sunk part to form decoration with a certain shape and color, and spraying a transparent color protective agent after hardening and polishing to finish the preparation.
For the surface needing special treatment, a facing die is selected for carrying out impression treatment, and corresponding colors are sprayed on the surface after forming, so that the molding with different requirements is met.
For concrete needing exposed aggregate (stone and ceramsite), spraying retarder when not being condensed, and after the strength requirement is met, performing surface scouring treatment to form the effect of exposed aggregate.
Compared with the prior art, the concrete decorative plate prepared by the invention can realize the matching of colors and shapes, and has excellent compressive strength, wear resistance and durability. The solid waste fly ash of the power plant is matched with different types of solid wastes, yellow river sand and the like to prepare fly ash ceramsite with different colors, and the fly ash ceramsite is added into concrete, so that the color and the shape of the fly ash ceramsite can be displayed on the surface of the concrete, a concrete decorative plate suitable for decorative plates, outdoor trestles, wood-like members and the like is formed, and the application of the ceramsite concrete is expanded.
