High-toughness modified aggregate inorganic artificial stone and preparation method thereof
The invention discloses a high-toughness modified aggregate inorganic artificial stone and a preparation method thereof, and solves the technical problems that in the prior art, an inorganic artificial stone process is complex and tedious, and the inorganic artificial stone is high in compression resistance and poor in bending resistance and deformation resistance. The concrete comprises 30-60% of white Portland cement, 30-80% of composite aggregate, 3-15% of superfine mineral powder, 0-10% of limestone powder, 0-10% of quartz powder and 0.05-5% of mixing liquid, wherein the superfine mineral powder accounts for 3-15% of the total powder; the composite aggregate comprises 2-30% of modified aggregate and 70-98% of common aggregate, and the modified aggregate comprises the following components in percentage by weight: 40-60% of common aggregate, 30-50% of a silane coupling agent and 1-5% of absolute ethyl alcohol. The inorganic artificial stone is integrally toughened, the silane coupling agent is used for modifying the quartz sand to improve the compatibility and affinity of the inorganic aggregate and the organic emulsion, the bending strength of the inorganic artificial stone is improved, and the conditions of edge breakage and corner falling in the transportation and installation process of the inorganic artificial stone are reduced.
本发明公开了一种高韧性改性骨料无机人造石及其制备方法，解决了现有技术中的无机人造石工艺复杂繁琐，且无机人造石的抗压能力强，但抗弯能力、变形能力差的技术问题。它包括30‑60%白色硅酸盐水泥、30‑80%复合骨料、3‑15%超细矿粉占、0‑10%石灰石粉占总粉料、0‑10%石英粉和0.05‑5%拌和液体；所述复合骨料包括2‑30%改性骨料和70‑98%普通骨料，所述改性骨料包括重量百分比的下述成分，40‑60%普通骨料、30‑50%硅烷偶联剂、1‑5%无水乙醇。本发明采用无机人造石整体增韧，通过硅烷偶联剂改性石英砂来提高无机骨料与有机乳液的相容性和亲和性，提高了无机人造石弯曲强度，减少无机人造石在运输及安装过程中的崩边、掉角情况发生。
