Abstract

The invention discloses composite spherical activated carbon added with polyester fibers and capable of improving mechanical strength. The composite spherical activated carbon is characterized by being prepared from raw materials in parts by weight as follows: 42-46 parts of cyclohexyl acrylate, 39-42 parts of alpha-methyl styrene, 25-28 parts of butyl formate, 2-3 parts of azodiisobutyronitrile, 2-2.5 parts of ethylene glycol dimethacrylate, 2-3 parts of gelatin, 1-1.5 parts of sodium metabisulfite, a proper amount of distilled water, a proper amount of acetone, 25-28 parts of sulfonated asphalt powder, 4-5 parts of the polyester fibers, 1-2 parts of a silane coupling agent kh560, 2-3 parts of graphene and 1-2 parts of sodium alginate. According to the composite spherical activated carbon, the polyester fibers and the graphene are added to an asphalt coating liquid, through a series of modification, the compound components can form a porous three-dimensional structure, the adsorbability of the composite spherical activated carbon to oil substances can be further improved, and the mechanical strength of an asphalt base can also be enhanced. The composite spherical activated carbon is high in purity, low-dust, abrasion-resistant, easy in flowing, easy to fill and broad in application prospect.

Description

technical field [0001] The invention relates to the field of materials, in particular to a composite spherical activated carbon with polyester fibers added to improve mechanical strength 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...
