Embodiment 1-5

[0039] A kind of low volatility disinfectant, its preparation method is:

[0040] S1. according to the proportioning in table 1, ethanol and propylene glycol are mixed to obtain mixed alcohol solution, nano molecular sieve is added in mixed alcohol solution, stand for 20min, obtain initial mixed solution, wherein nano molecular sieve particle size is 170nm;

[0041] S2. According to the proportioning of table 1, nano-zinc oxide sol, nano-titanium dioxide sol, nano-molecular sieve, and water are added to the initial mixed solution, mixed evenly, and sealed and stored to obtain a low-volatility disinfectant.

Abstract

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 99.9%, the antibacterial rate within 24 h reaches 88.2-96.9%, and the antibacterial rate within 72 h reaches 67.9-95.3%.

Description

technical field [0001] The present application relates to the field of disinfection technology, and more particularly, to a low-volatility disinfectant and a preparation method thereof. Background technique [0002] Disinfectant is a chemical used for disinfection and sterilization in daily life. Disinfectants can kill pathogenic microorganisms on the transmission medium, eliminate pathogenic microorganisms outside the human body, cut off the transmission route of infectious diseases, and achieve the purpose of controlling infectious diseases. . [0003] There are various types of disinfectants, and disinfectants can be divided into sterilants, high-efficiency disinfectants, medium-efficiency disinfectants, and low-efficiency disinfectants according to their level of action. The sterilant can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, chlorine dioxide, chlorine, c...
