The invention discloses anti-radiation bionic quartz stone and a preparing method thereof. The preparing method includes the following steps that A, modified resin is prepared; B, by weight, 80-90% of quartz, 8-12% of modified resin, 0.01-1% of curing agent, 0.01-1% of coupling agent, 1-5% of nanometer bamboo charcoal, 1-3% of aluminum hydroxide powder and 0.1-2% of pigment are stirred uniformly to obtain a mixed material; C, the mixed material is distributed on a template for the first time, vibration pressing forming, demolding and cutting are carried out, and the mixed material is arrayed according to a preset pattern to obtain a semi-finished product; secondary material distribution is carried out, vibration pressing forming and drying forming are carried out, and then the finished product is obtained through postprocessing. Compared with existing bionic quartz stone, the manufactured bionic quartz stone is scientific in matching, reasonable in preparation, stable in performance, high in mechanical strength and not prone to deformation or ageing. The bionic quartz stone has excellent antibacterial, deodorizing and anti-radiation performance by reasonably matching the nanometer bamboo charcoal, deodorant and antibacterial powder, and the application range of the bionic quartz stone is further broadened.
