Description
Technical Field
The invention relates to a disinfectant, which can be used for personal cleaning, object surface disinfection, air disinfection and medical instrument surface disinfection and belongs to the field of long-acting disinfectants.
Background
The disinfectant is used for killing pathogenic microorganisms on a medium to make the medium achieve the harmless requirement. In recent years, increased attention has been paid to public and personal care. The disinfection and sterilization become almost necessary work in daily work and life, and the supply of disinfectant products is insufficient. Generally, the method can be divided into a plurality of application occasions such as air disinfection, skin disinfection, object surface disinfection, medical instrument disinfection and the like. The quaternary ammonium salt disinfectant is one of the most commonly used main components of the current disinfectant, can be adsorbed on the surface of bacteria or viruses, and the hydrophobic part of the disinfectant permeates into the rice lipid layer of bacteria or virus cells, so that the permeability of cell walls and cell membranes of the disinfectant is changed, the activity of enzyme activity protein is inhibited, and the metabolic process of the cells is influenced. Quaternary ammonium salt disinfectants have been derived from 7 generations at present, and the mature quaternary ammonium salt disinfectants in the market of China mainly comprise alkyl dimethyl benzyl chloride/ammonium bromide containing benzyl, alkyl trimethyl chloride/ammonium bromide or tetradecyl-2-methylpyridine ammonium bromide containing pyridine. However, researches show that the sterilizing effect of a single quaternary ammonium salt disinfectant in some environments is greatly limited, in recent years, various compound quaternary ammonium salt disinfectants show more excellent sterilizing and disinfecting effects, the antibacterial effect of the compound quaternary ammonium salt disinfectants can be improved by 4-20 times, and the compound quaternary ammonium salt disinfectants have good prospects in the current disinfectant development. However, there are some problems to be raised, most notably that the antibacterial time efficiency is short, the sterilization capability for a long-term sterilization environment can be kept insufficient, and the biocompatibility needs to be further improved.
To achieve long-term disinfection, the main approach is to kill bacteria or viruses on the surface of the article, and to prevent the adhesion of bacteria and viruses on the surface, so as to prevent the continuous proliferation of living bacteria with very small adhesion with the passage of time. In recent years, antibacterial adhesive materials have been rapidly developed. Among them, many polymers and neutral natural polysaccharides can also achieve the effect of binding water molecules through hydrogen bond receptors such as hydroxyl groups, such as polyethylene glycol (PEG), which has excellent hydrophilicity and can bind a large amount of water, forming a 'space exclusion' and hydration layer by surrounding molecular chain hydrogen bonds to resist the adhesion of bacteria and viruses, achieving the effect of prolonged disinfection. In addition, the zwitterionic polymer also has the characteristics of extremely strong hydrophilicity, excellent thermal and chemical stability, excellent biocompatibility, good pollution resistance and the like. Meanwhile, the polymers have good biocompatibility, and have potential application prospects in the aspect of long-acting disinfection.
Disclosure of Invention
The invention aims to disclose a quaternary ammonium salt/antibacterial adhesion polymer long-acting disinfectant, which overcomes the defects of the prior quaternary ammonium salt disinfectant and simple mixed disinfectant, improves the disinfection effect, prolongs the disinfection time, and provides a disinfectant which is safe, nontoxic, harmless and non-irritant to human bodies; no corrosion to equipment; long-acting disinfectant without environmental pollution.

The balance being auxiliary additives such as: fatty alcohol-polyoxyethylene ether, menthol and the like, and the content of the fatty alcohol-polyoxyethylene ether and the menthol is less than 0.2 percent.
The preparation method of the quaternary ammonium salt/antibacterial adhesion polymer long-acting disinfectant comprises the following steps:
(1) 0.5L of antibacterial nonspecific polymer (polyethylene glycol and polysulfonate betaine methacrylate) with mass concentration of 0.2-6% is prepared for later use.
(2) 0.4-4 percent of dodecyl trimethyl ammonium chloride, 0.05-0.5 percent of benzalkonium bromide and 0.25L of 2-14.2 percent of urotropine solution are prepared for later use.
(3) And (3) mixing the solutions in the step (1) and the step (2), and uniformly stirring. Then, an appropriate amount of auxiliary additives is added as required.
(4) And (4) fixing the volume of the mixed solution obtained in the step (3) to 1L, stirring, and filling to obtain the long-acting disinfectant.
Compared with the prior art, the invention has the following beneficial effects: the disinfectant with long acting and different application environments is obtained by combining the polymer with the non-specific adhesion of bacteria and viruses and quaternary ammonium salt with the disinfection function through different compatibility. The average sterilization rate of the compound on influenza A virus H1N1 is more than 99.99%, the average sterilization rate on enterovirus-71 is more than 81.43%, and the biological behavior of normal cells is not influenced. Meanwhile, the polymer with the function of resisting bacteria adhesion prevents bacteria adhesion, effectively prolongs the disinfection effect and improves the biocompatibility of the quaternary ammonium salt disinfectant.
