Classification of artificial stone
1. Resin type artificial stone resin type uses unsaturated polyester resin as cementing agent, and natural marble, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and then adds catalyst, curing agent, pigment, etc. The artificial stone agent is processed by mixing and stirring, curing and molding, demoulding and drying, and surface polishing. Products using unsaturated polyester have good gloss, bright and rich colors, strong processability, and good decorative effect; this resin has low viscosity, is easy to form, and can be cured at room temperature. The molding methods include vibration molding, compression molding and extrusion molding. The artificial stone used in interior decoration projects is mainly resin type.
2. 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 a cement mortar body, and then the body is immersed in an 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 cementing materials can be used as quick-hardening cement, white cement, ordinary Portland cement, aluminate cement, fly ash cement, slag cement and plaster of paris. The organic monomers can be styrene, methyl methacrylate, vinyl acetate, acrylonitrile, butadiene, etc. These monomers can be used alone or in combination. The cost of composite artificial stone products is low, but the polyester surface is prone to peeling or cracking after being affected by the temperature difference.

3. Cement-type artificial stone Cement-type artificial stone is an artificial stone made of various cements as cementing materials, sand and natural gravel as coarse and fine aggregates after preparation, stirring, pressure steam curing, polishing and polishing. . In the preparation process, the color material can be mixed to make colored cement stone. The production of cement-type stone is convenient and cheap, but its decoration is poor. Terrazzo and all kinds of stepped tiles belong to this category.
Because unsaturated polyester resin has the characteristics of low viscosity and easy molding; good gloss; light color, easy to prepare various bright colors and patterns; fast curing, can be operated at room temperature, etc. Extensive is a resin-type artificial stone produced with unsaturated polyester resin as a binder. It has stable physical and chemical properties and a wide range of applications. It is also called polyester synthetic stone.
