Abstract

The invention discloses bactericidal composite spherical activated carbon. The bactericidal composite spherical activated carbon is characterized by being prepared, by weight, by the following raw materials of 45-50 parts of butyl acrylate, 40-43 parts of vinyl butyrate, 1-2 parts of potassium persulfate, 1-2 parts of benzoyl peroxide, 1.5-2 parts of trihydroxymethylpropyl trimethylacrylate, 25-28 parts of ethyl alcohol, 1-2 parts of stearic acid monoethanolamine, appropriate distilled water, appropriate acetone, 25-28 parts of sulfonated asphalt powder, 2-3 parts of silver peroxide, 1-2 parts of gelatin, 3-4 parts of nano-titanium dioxide, 0.4-0.6 part of titanate coupling agent TC-2 and 0.3-0.4 part of sodium tripolyphosphate. According to the bactericidal composite spherical activated carbon and a preparation method thereof, the nano-titanium dioxide and the silver peroxide are added to serve as asphalt coating materials, and good bactericidal and antibacterial functions are achieved; meanwhile, the materials are uniformly distributed on the surfaces of resin polymer pellets, the bactericidal composite spherical activated carbon is in the shape of a sphere with uniform size, the sphere is easy to roll, the ash content is less, the hardness is high, the regeneration is easy, and the bactericidal composite spherical activated carbon is suitable for water treatment.

Description

technical field [0001] The invention relates to the field of materials, in particular to a bactericidal composite spherical activated carbon and a preparation method thereof. Background technique [0002] Spherical activated carbon has been widely used in related fields such as medicine, environmental protection and catalyst carrier because of its good sphericity, high packing density, less particle shedding and fast adsorption and desorption speed. Spherical activated carbon is mainly divided into three categories according to different raw materials: coal-based spherical activated carbon, polymer resin-based spherical activated carbon and pitch-based spherical activated carbon. Among them, coal-based spherical activated carbon has the advantages of cheap raw materials and wide sources, but coal-based activated carbon has high ash content, many impurities, and low mechanical strength, which limits its application and development. Spherical activated carbons prepared with p...
