Low-volatility disinfectant and preparation method thereof

The invention relates to the field of disinfection technologies, and particularly discloses a low-volatility disinfectant and a preparation method thereof. The low-volatility disinfectant is prepared from the following raw materials: 50 to 70 parts of ethanol, 20 to 30 parts of propylene glycol, 20 to 40 parts of nano zinc oxide sol, 20 to 30 parts of nano titanium dioxide sol, 35 to 50 parts of nano molecular sieve and 20 to 30 parts of water. The preparation method comprises the following steps: S1, mixing ethanol and propylene glycol to obtain a mixed alcohol solution, adding the nano molecular sieve into the mixed alcohol solution, and standing for 15-20 minutes to obtain a primary mixed solution; s2, adding the rest raw materials into the primary mixed solution, and sealing and storing to obtain the disinfectant. The average value of the killing rates of the disinfectant for four bacteria including staphylococcus aureus, escherichia coli, pseudomonas aeruginosa and candida albicans within 0.5 min reaches
