Classification Of Artificial Stone Types

Resin based artificial stone
Resin based artificial stone is made by mixing unsaturated polyester resin as a binder with natural marble, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and then adding catalysts, curing agents, pigments and other additives. It is processed through processes such as mixing and stirring, curing and shaping, demolding and drying, surface polishing, etc. Products using unsaturated polyester have good luster, bright and rich colors, strong processability, and good decorative effects; 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 indoor decoration engineering is mainly resin type.
Composite artificial stone
The adhesive 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 body of cement mortar, and then the body is immersed in organic monomers to polymerize 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 bonding materials can include fast hardening cement, ordinary Portland cement, aluminate cement, fly ash cement, slag cement, and gypsum. Organic monomers such as styrene, methyl methacrylate, vinyl acetate, acrylonitrile, butadiene, etc. can be used alone or in combination. The cost of composite artificial stone products is relatively low, but their polyester surface is prone to peeling or cracking due to temperature differences.
Cement based artificial stone
Cement based artificial stone is made by using various types of cement as the bonding material, sand and natural crushed stone particles as coarse and fine aggregates, and then preparing, mixing, pressure steam curing, polishing, and finishing the artificial stone. During the preparation process, adding colorants can produce colored cement paste. The production of cement-based stone materials is convenient and cost-effective, but its decorative properties are poor. Terrazzo and various types of terracotta bricks belong to this category.
Sintered artificial stone
The production method of sintered artificial stone is similar to ceramic technology, which involves mixing powder materials such as feldspar, quartz, diabase, calcite, hematite powder, and a certain amount of aged soil together. The general ratio is 60% stone powder and 40% clay. The raw material is prepared by mixing slurry method, formed by semi dry pressing method, and then baked at a high temperature of about 1000 ℃ in a kiln. Sintered artificial stone has good decorative properties and stable performance, but it requires high-temperature roasting, resulting in high energy consumption and high cost.
Due to the low viscosity and ease of molding of unsaturated polyester resin; Good luster; Light in color, easy to mix into various bright colors and patterns; Due to its fast curing and ability to operate at room temperature, the resin based artificial stone produced using unsaturated polyester resin as a binder is the most widely used among the above-mentioned stone materials. Its physical and chemical properties are stable, and it has a wide range of applications, also known as polyester synthetic stone.
