Artificial stone is a kind of artificial synthetic decorative material. According to different binders, it can be divided into organic artificial stone and inorganic artificial stone. Artificial stone is divided into 4 categories according to its production process and raw materials used: cement type (silicate type) artificial stone, resin type (polyester type) artificial stone, composite artificial stone and sintered artificial stone. Among the four artificial stone decoration materials, organic (polyester type) is the most commonly used, with the best physical and chemical properties.

　　1. Cement-type (silicate-type) artificial stone Cement-type artificial stone is made of various cements as adhesive materials, sand and natural gravel particles are coarse and fine aggregates, which are prepared, stirred, pressurized and steamed to be polished and polished. Artificial stone made afterwards. In the configuration process, color materials can be mixed to make colored cement stone. The cement usually used is Portland cement. Now aluminate cement is also used as a binder. The artificial marble made of it has high surface gloss, durable patterns, weather resistance, fire resistance, and moisture resistance. marble.

　　2. Resin type (polyester type) artificial stone. Resin type artificial stone is based on unsaturated polyester resin as the adhesive, combined with natural marble crushed stone, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and then added catalyst , Curing agent, pigment and other additives, processed by mixing and stirring, curing forming, demoulding and drying, surface polishing and other processes. Unsaturated polyester products have good gloss, bright colors, strong workability, and good decorative effects; this resin has low viscosity, is easy to shape, and can be cured at room temperature. The molding methods include vibration molding, compression molding and extrusion molding. The artificial stone used in the interior decoration project is mainly formed by resin.

　　3. Composite artificial stone The binder used in composite artificial stone includes both inorganic materials and organic polymer materials. The production process is as follows: first, cement, stone powder, etc. are used to make the embryo body of cement mortar, and then the embryo body is immersed in organic monomer to polymerize it under certain conditions. For the board, the bottom layer is made of stable and inexpensive inorganic materials, and the surface layer is made of polyester and marble powder. Inorganic glue materials can be fast hardening cement, white cement, ordinary portland cement, vinyl acetate, butadiene, etc. These monomers can be used alone or in combination. The cost of composite artificial stone products is lower, but the polyester surface is prone to peeling or cracking after being affected by the temperature difference.

　　4. Sintered artificial stone The production method of sintered artificial stone is similar to the ceramic process. It is to mix feldspar, quartz, pyrochlore, calcite and other powders with hematite powder and a certain amount of kaolin. The general ratio is It is made of 60% stone powder and 40% clay. The billet is prepared by the mixing method, formed by the semi-dry pressing method, and then calcined in a kiln at a high temperature of about 1000 degrees Celsius. Sintered artificial stone has good decorative properties and stable performance, but it needs high-temperature roasting, so it consumes a lot of energy and is expensive.
