Abstract

The invention relates to a preparation method of a filter material for filtering. The preparation method is characterized by comprising the following process steps: (1) processing activated carbon and zeolite at high temperature of 350-500 DEG C for 5-10h; (2) heating epoxy resin at temperature of 80-100 DEG C for 12-24h, then washing with 0.1-0.2mol / L diluted hydrochloric acid; (3) uniformly mixing the epoxy resin processed in the step (2), the activated carbon processed in the step (1), the zeolite processed in the step (1), negative ion powder and an adhesive to obtain a clay-shaped mixture; and (4) forming the clay-shaped mixture obtained in the step (3) in a mould to obtain a filter material blank body, and performing air drying on the filter material blank body at room temperature for 12-24h to obtain the filter material for filtering. The filter material is low in manufacture cost, and can achieve a good filtering effect; meanwhile, constant negative ions of air can be generated, and bacterium resisting and killing functions are achieved, thus bacteria are effectively filtered.

Description
