The invention discloses a terahertz plastic master batch with antibacterial, mildew-proof, odor-removing and fresh-keeping functions and a preparation method thereof. The terahertz plastic master batch comprises the following raw materials in parts by weight: 3-60 parts of terahertz powder and 60-100 parts of resin. The preparation method comprises the following steps: adding the raw materials andauxiliary materials into a screw extruder, extruding, bracing, cooling, dicing to obtain master batch, and irradiating by a terahertz electron generator to obtain the plastic master batch with the terahertz antibacterial, mildew-proof, odor-removing and fresh-keeping functions. The processing frequencies of the terahertz wave electron generators are 1 * 1011 Hz, 5.5 * 1011 Hz, 1.1 * 1012 Hz, 5.5* 1012 Hz, 1.1 * 1013 Hz and 5 * 1013 Hz; the plastic master batch with the terahertz antibacterial, mildew-proof, odor-removing and fresh-keeping functions, prepared by the method, is broad-spectrumantibacterial, and the anti
