The invention provides a corrosion-resistant artificial stone and a preparation method thereof. The corrosion-resistant artificial stone is prepared from the following raw materials in percentage by weight: 4-9% of vinyl resin, 0.5-1.5% of a curing agent and the balance of quartz sand, wherein the content of styrene in the vinyl resin does not exceed 35%; and the viscosity of the vinyl resin is 0.20-0.65 Pa.s. By using the vinyl resin with specific viscosity and specific styrene content and matching with the high-energy pressing process, the linear thermal expansion coefficient of the prepared artificial stone is less than 2.5*10<-5>, the volume change is small under the condition of temperature change, and the dimensional stability is good; and the artificial stone can be applied to walls and grounds, and has excellent corrosion resistance, wherein the corrosion-resistant level reaches the UA level, and the application scene of the artificial stone is broadened. Meanwhile, the artificial stone has few components, no new component is added, the preparation process is simple, and industrial large-scale production can be realized.
本发明提供了一种耐腐蚀的人造石及其制备方法，原料包括如下重量百分比组分：乙烯基树脂4～9％、固化剂0.5～1.5％，余量为石英砂；所述乙烯基树脂中苯乙烯含量不超过35％；所述乙烯基树脂的粘度为0.20～0.65Pa.s。本发明通过使用特定粘度和特定苯乙烯含量的乙烯基树脂，再配合本发明高能量的压制工艺，制得的人造石线性热膨胀系数小于2.5x10‑5，在温度变化的情况下体积变化小，尺寸稳定性好，可应用于墙面和地面，且具有优异的耐腐蚀性能，耐腐蚀级别达到了UA级，拓宽了人造石的应用场景。同时本发明人造石组分少，未添加新组分，制备工艺简单，可实现工业化大规模生产。
