A composite plate is mainly made from the following raw materials in percentage by weight: 35% to 45% of calcium carbonate, 45% to 55% of cullet, 5% to 15% of unsaturated polyester resin, 0.1% to 1% of a curing agent, 0.1% to 1% of an auxiliary agent, wherein a ratio of an amount of the calcium carbonate to an amount of the cullet is 0.75%. The invention employs cullet, calcium carbonate, and resin as the main raw materials to prepare an artificial stone plate; no natural quartz is used, and hence the raw material cost is low. A reasonable ratio of cullet to calcium carbonate reduces the use of resin, which further reduces the raw material cost. Through a reasonable combination of different raw materials, the composite plate of the invention has physical and chemical properties and decorative abilities that are similar to those of traditional artificial quartz stone. |
