Method for preparing artificial stone from coal gangue
The invention provides a method for preparing artificial stone from coal gangue, and belongs to the technical field of solid waste utilization, and the method comprises the following steps: S1, crushing and grinding coal gangue into coal gangue powder; s2, roasting the coal gangue powder in an oxygen-containing atmosphere for a period of time to obtain carbon-removed coal gangue powder; s3, uniformly mixing the carbon-removed coal gangue powder with epoxy resin according to a certain proportion to obtain a precursor mixture; and S4, transferring the precursor mixture into a molding press, and carrying out mold pressing for a certain time at a certain mold pressing temperature and pressure, so as to obtain the artificial stone. The raw materials are convenient to obtain, the preparation process is simple, and the prepared artificial stone has good physical properties.
本发明提供了一种利用煤矸石制备人造石的方法，属于固体废物利用技术领域，包括：步骤S1、将煤矸石破碎、研磨为煤矸石粉；步骤S2、将煤矸石粉末在含氧氛围中焙烧一段时间获得除碳的煤矸石粉；步骤S3、将除碳的煤矸石粉与环氧树脂按一定比例混合均匀获得前驱体混合物；步骤S4、将前驱体混合物转移至模压机中并在一定的模压温度、压力下模压一定时间，得到人造石。本发明原料获取方便且制备工艺简单，所制备的人造石具有较好的物理性能。
