Artificial stone and preparation method thereof
The invention provides an artificial stone and a preparation method thereof, and the artificial stone is prepared from the following raw materials in percentage by weight: 15-25% of an adhesive, 20-45% of carbonized sludge and the balance of quartz powder, the preparation method of the artificial stone comprises the following steps: mixing an adhesive, carbonized sludge and quartz powder according to a weight ratio, and homogenizing to obtain a mixed material; under the condition that the vacuum degree is lower than 5 kPa, the mixed material is pressed for 10-20 min in a mold under the pressure not lower than 2 MPa; and naturally curing for 3-5 days after demolding. The carbonized sludge is used as a production raw material of an artificial stone product, so that waste utilization is realized, and environmental pollution and burden are reduced. According to the present invention, the non-sintered artificial stone is prepared in the adhesive curing manner so as to easily save energy, and the research results show that the use amount of the adhesive is increased, the Moh's hardness, the impact resistance and the compression strength of the carbonized sludge and adhesive cured artificial stone are rapidly enhanced, the water absorption rate is rapidly reduced, and the product performance is substantially improved.
本发明提供了一种人造石及其制备方法，本发明的人造石由以下重量百分比的原料制备得到，胶黏剂15％～25％、碳化污泥20％～45％和余量的石英粉；本发明的人造石的制备方法包括步骤：将胶黏剂、碳化污泥、石英粉按重量比例混合后均质，得到混合物料；在真空度低于5kPa的条件下，以不低于2MPa的压力在模具中对混合物料压制10～20min；脱模后自然固化3～5天。本发明以碳化污泥为人造石产品的生产原料，实现了废物利用，减少了环境污染和负担。本发明以胶黏剂固化的方式制备非烧结的人造石有利于节约能源，研究中发现，胶黏剂用量增加，碳化污泥与胶黏剂固化的人造石莫氏硬度、抗冲击能力、和压缩强度急剧增强，而吸水率急剧降低，产品性能得到极大提升。
