Preparation method of clay-based cat litter

The invention discloses a preparation method of clay-based cat litter. The clay-based cat litter is prepared from the following raw materials in percentage by weight: 50-70% of a clay-based active silicon source, 5-10% of clay-based nano hectorite, 0.1-10% of tea residue powder, 0.001-0.005% of nano silver ions, 0.1-1% of graphene and the balance of ionized water. Benefited from the high activity of the clay-based active silicon source and the uniqueness of the synthesis method, the invention relates to the technical field of cat litter, the method is simple and convenient, the prepared clay-based cat litter avoids the use of chemical raw materials, the preparation cost of traditional cat litter synthesis is greatly reduced, and the clay-based cat litter has the remarkable characteristics of sterilization, natural waste and the like, and has a wide application prospect. A new way is provided for high value-added development and comprehensive utilization of clay resources. 本发明公开了一种黏土基猫砂的制备方法，其原料的重量百分比为黏土基活性硅源5
