The invention discloses a double-layer multi-surface light absorption material for chemical reagent storage, and belongs to the technical field of light absorption materials. The double-layer multi-surface light absorption material for chemical reagent storage comprises, by weight, 50-75 parts of nano-silica, 10-15 parts of a magnetic liquid, 30-50 parts of a colorant, 2-5 parts of an assistant, 5-8 parts of a thickener, 2-3 parts of cerium oxide and 20-25 parts of a settling agent. The nano-silica can be used as a carrier and is immobilized with the colorant while being physically modified, so the light absorption material has the properties such as paramagnetism, dispersity and continuity; a uniform magnetic field is applied after the glass raw materials are mixed, and the continuity ofthe magnetic field is used for guiding filling arrangement of the light absorption material, so the compactness obtained in the invention is remarkably better than the compactness obtained by a traditional mixing mode; and diamond faces are formed on the inner wall and the outer wall of the finished product in cooperation with a mold, so the light absorption area and diffuse reflection are improved, and the double-layer multi-surface super-strong light absorption effect is achieved.
