Artificial stone with irregular pore and preparation method thereof

Abstract

The invention provides an artificial stone with irregular pores and a preparation method thereof. The artificial stone composed of a cementitious material, a pore forming agent and a thickener is prepared by the following method: preparing a slurry; casting the prepared slurry in a mould; and vibrating for molding in a vibration table. Compared with the natural stone, the artificial stone with irregular pores provided by the invention has the advantages of low cost, multiple effect changes, environment-friendliness, no radiation, low density, excellent thermal insulation, sound insulation and refractory properties, and good mechanical property; and the artificial stone with irregular pores has strong durability and color stability in all kinds of weather conditions, and is an ideal decorative material.

Description

technical field [0001] The invention relates to an artificial stone, in particular to an artificial stone with irregular holes and a preparation method thereof. Background technique [0002] Travertine is named for the many holes on the surface of the stone. It is mainly used in building exterior wall decoration and interior floor and wall decoration. The buildings it decorates often have strong cultural and historical charm, and are used by many buildings in the world. Out of business needs, and absorbing the successful experience of foreign countries, more and more construction projects use travertine, which meets the needs of a multicultural development and is a model of ancient building materials applied to modern buildings. [0003] Due to the existence of a large number of holes, the volume density is low, the water absorption rate is increased, and the strength is reduced, so the physical performance index is lower than the normal marble standard. At the same time, ...

AI Technical Summary

Problems solved by technology

Due to the complex process of artificial travertine produced by resin mixed with stone powder, the hazards of volatile organic compounds in the production process, and the high energy consumption, high cost, and high volume density of the product, only dry-hanging construction can be used, and the construction cost is high. As a high-end product application is subject to certain restrictions

Another method is to use the silicone or resin glue mold with uneven surface to spray the complexion, then add the surface paste and base material, and then cure and demould the cultural stone process to obtain the product. This method has the disadvantages of poor durability and easy shrinkage of the soft mold. Deformation, the product is prone to large size deviations, the holes only exist on the outer surface and the inner angles are less than 90 degrees, and the overall strength is poor, the color depends on the adhesion of cement and only exists on the surface, and it is easy to powder and fade when exposed for a long time, which seriously affects the decoration. The disadvantage of the effect
