Abstract

The invention discloses an artificial travertine hole mold and a cement-based non-burning artificial travertine preparation method. The cement-based non-burning artificial travertine preparation method comprises the following steps: (1) using the mold to form solid phase change materials in different shapes with a phase change material as an injection molding material; (2) arranging the solid phase change materials on the bottom surface of the mold; (3) adding a cementing material and an aggregate into a mixing device for uniform mixing, then adding an admixture, a water reducing agent and water into the mixing device for uniform mixing, adding the mixed materials into the mold evenly for forming and curing, demolding after the materials are completely solidified and conducting surface finishing polishing on the side with the solid phase change materials; (4) placing a finished product in a constant temperature device, taking the product out after the phase change materials are turnedinto the liquid state and flow out completely at a specific temperature, and cooling to the room temperature; (5) spraying an acid solution to the side of the artificial travertine with holes and cleaning with water after standing to obtain the cement-based non-burning artificial travertine.

Description

technical field [0001] The invention belongs to the field of building decoration materials, in particular to an artificial travertine hole mold and a preparation method of cement-based non-burning artificial travertine. Background technique [0002] Natural travertine is a type of rock formed through continental deposition, with stacked and alternate accumulation lines. Natural travertine mainly contains calcium carbonate, which tends to produce gaps during the accumulation process. After water stays in the gaps for a long time, it will dissolve and corrode the calcium carbonate, thus forming many holes of different sizes and shapes. The existence of special accumulation lines and irregular holes endows natural travertine with atmosphere, elegance and high-end temperament. Travertine originated in ancient times, but it has a strong sense of modernity and high-end. The rich and varied textures are clearly visible and highly decorative, making Travertine favored by architectu...
