The production method of sintered artificial stone is similar to that of ceramic technology. It is to mix feldspar, quartz, diabase, calcite and other powders with hematite powder and a certain amount of kaolin. The ratio is 60% of stone powder and clay 40%. The artificial stone is prepared by the mixing method, shaped by semi-dry pressing, and then fired in a kiln at a high temperature of about 1000°C. Sintered artificial stone has good decoration and stable performance, but it needs to be roasted at high temperature, so it consumes a lot of energy and costs high. Because unsaturated polyester resin has the characteristics of low viscosity, easy to shape; good gloss; light color, easy to prepare various bright colors and patterns, fast curing, and can be operated at room temperature. Therefore, among the above-mentioned stone materials, the resin-type artificial stone produced with unsaturated polyester resin as a cementing agent is widely used at present. It has stable physical and chemical properties and a wide range of applications. It is also called polyester synthetic stone.
