The invention provides an artificial stone preparation method. The artificial stone preparation method comprises the following steps of S1, crushing raw stone; S2, carrying out color sorting screening; S3, grinding into powder; S4, mixing and modifying; S5, carrying out vacuum pressing; and S6, carrying out surface treatment. The artificial stone preparation method has the beneficial effects that multi-stage crushing is carried out on raw stones, and crushed products of different sizes are obtained, and the raw stones are fully utilized; color sorting screening is carried out on a crushed product, a stone with color reaching the standard is obtained through screening, so that the situation that the purity of stone powder is affected, and consequently, the color of a manufactured artificial stone plate does not reach the standard is avoided; the screened material is ground into powder, and mixing and modifying are carried out on the stone powder; so that the compressive strength and breaking strength of the artificial stone are improved and the powder expansion coefficient is reduced to improve the thermal transition point of the artificial stone; and vacuum pressing is carried out on the modified product, so that the gas content in the artificial stone is low, and the mechanical properties such as compressive strength and toughness are improved.
本发明提供了一种人造石制备方法，包括以下步骤；S1原石破碎；S2色选筛除；S3研磨成粉；S4混合改性；S5真空压制；S6表面处理；本发明的有益效果：将原石进行多级破碎，得到不同尺寸的破碎产物；将原石物尽其用；对破碎后的产物进行色选筛除；筛除得到颜色达标的石料，以免影响石粉的纯度，导致制造出来的人造石板材颜色不达标；筛选得到的料进行研磨成粉；对石粉进行混合改性；提高人造石的抗压强度、抗折强度，降低粉膨胀系数以提高其热转变点；对改性后的产物进行真空压制，使得人造石内气体含量低，提高抗压强度、韧性等力学性能。
