Novel composite cement-based artificial stone and preparation method thereof
The invention discloses a novel composite cement-based artificial stone and a preparation method thereof, and relates to the technical field of building stones. The artificial stone comprises a surface layer and a substrate layer; the substrate layer comprises the components in percentage by weight: 10-25% of cement, 70-85% of an aggregate composition A, 1-10% of an additive A and 0-0.3% of water; the aggregate composition A comprises the components in percentage by weight: 50-70% of quartz sand, 15-30% of cullet, 5-10% of modified limestone particles and 5-10% of unsaturated resin; the surface layer comprises the components in percentage by weight: 20-35% of cement, 60-75% of an aggregate composition B, 1-10% of an additive B and 0-0.3% of water; and the aggregate composition B comprises the components in percentage by weight: 50-70% of quartz sand, 15-30% of river sand, 5-10% of modified limestone particles, 5-10% of unsaturated resin and 5-10% of glass fibers. The modified limestone particles are adopted to replace traditional common limestone particles, the oil absorption value of a processed product can be effectively reduced, meanwhile, the strength is enhanced, and the water absorption is reduced.
本发明公开了一种新型复合型水泥基人造石材及制备方法，涉及建筑石材技术领域。本发明人造石材包括表层和基底层；基底层以重量百分比包括水泥10‑25％、骨料组合物A70‑85％、外加剂A1‑10％以及水0‑0.3％；骨料组合物A以重量百分比计包括石英砂50‑70％、碎玻璃15‑30％、改性石灰石颗粒5‑10％、不饱和树脂5‑10％；表层以重量百分比计包括水泥20‑35％、骨料组合物B60‑75％、外加剂B1‑10％以及水0‑0.3％；骨料组合物B以重量百分比计包括石英砂50‑70％、河砂15‑30％、改性石灰石颗粒5‑10％、不饱和树脂5‑10％和玻璃纤维5‑10％。本发明采用改性石灰石颗粒替换传统的普通石灰石颗粒，可以有效的降低加工后的产品的吸油值，同时增强了强度，降低了吸水性。
