Problems solved by technology

[0004] Resin-type artificial stone is greatly limited in its application fields because the cementing material used is organic resin. For example, the resin is easily aged and brittle under strong ultraviolet radiation, so it cannot be used outdoors; the resin is easily defor

Abstract

The present invention discloses an artificial stone production method, which is based on a geopolymeric cement material. The artificial stone production method includes the following procedures: A. An artificial stone square stock is made of a cementing material and an aggregate with a vacuum vibration compact compressing method. A geopolymeric cement material serves as the cementing material and a carbonate mineral serves as the aggregate. B. The artificial stone square stock is withdrawn from the vacuum environment with a mould and is hardened in maintenance. C. After ejected from the mould, the square stock is cut, polished, protectively treated and became an artificial stone board. The artificial stone board produced by the present production method has the advantages that the raw material is cheap and that the product, which is decorative, has the quality and texture of a natural stone. In addition, the production method has a special technology, consumes little energy, protects the environment, cyclically utilizes natural gravels, saves natural sources and conforms to the development direction of modern novel decoration materials.

Description

technical field [0001] The invention relates to the technical field of building materials for decoration, in particular to artificial stone based on geopolymeric cementitious materials and a production method thereof. Background technique [0002] Artificial stone or man-made synthetic stone is essentially concrete used in the decorative field. When resin is used as an adhesive and is rich in decorative effect of crushed stone aggregate, it is decorative resin concrete. [0003] At present, the popular artificial stone products on the market generally use resin, especially unsaturated polyester materials as adhesives, so they are classified as resin-type artificial stone. [0004] Resin-type artificial stone is greatly limited in its application fields because the cementing material used is organic resin. For example, the resin is easily aged and brittle under strong ultraviolet radiation, so it cannot be used outdoors; the resin is easily deformed under high temperature co...
