Artificial caverous stone and its making process

Abstract

The present invention discloses one kind of artificial cavernous stone and its making process. Mold of soft material with excellent deforming performance is used in making the artificial cavernous stone. The artificial cavernous stone of the present invention has excellent texture similar to that of natural cavernous stone, selectable color and sizes and other advantages, and is used as building decorating material.

Description

technical field [0001] The invention relates to a new type of building and decorative stone and its preparation method, in particular to an artificial travertine with real holes and its preparation method. Background technique [0002] Travertine is named because of the many holes on the surface of the stone. The scientific name of the stone is tuff or travertine. Commercially, it is classified as marble. Travertine has many changes in color and texture, rich texture and clear stripes, which can make the decorated buildings show a strong cultural and historical charm, so it is often used as a covering decoration material in buildings. [0003] The formation of natural travertine is generally considered to be a calcareous material precipitated from carbonate-bearing spring water (usually a hot spring) under atmospheric conditions. The specific formation is that the circulating groundwater containing carbon dioxide takes away a large amount of calcareous carbonate in the solu...

Problems solved by technology

In order to meet the needs, there are also artificial travertine products on the market in our country at present. However, because the inner angles of the holes in the travertine are generally less than 90 degrees, it is difficult to use a mold to support it. Artificial travertine with real holes cannot be mass-produced by the method of preparing molds

The so-called artificial travertines currently on the market are all flat imitation travertines. The imitation of the holes is to cause the difference in color between the hole and the surrounding surface due to the depth of the color, thus showing the visual effect of the hole, but it is not the real meaning. The artificial travertine with holes on the surface, the texture and decorative effect of this flat imitation travertine are quite different from the natural travertine

In addition, there is a product that is also sold in the name of artificial travertine. In fact, during the production process, some small air bubbles are formed due to the interaction of cement and other raw materials with air, and some small round holes are left after drying. Holes, the salesperson also calls it "travertine" for sale, but in fact it is obviously different from the holes on the real travertine, so it is not a real travertine product
