Description
Technical Field
The invention relates to a low-temperature efficient compound disinfectant, in particular to a preparation method for preparing a low-temperature efficient compound disinfectant by a chemical method.
Background
The novel coronavirus can cause infection (direct transmission) by sneezing, coughing and speaking droplets of a patient, and the exhaled gas is directly inhaled in a short distance, and also can cause infection (contact transmission) because the droplets are deposited on the surface of an article and contact mucous membranes such as oral cavity, nasal cavity, eyes and the like after contacting a polluted hand. Certain disinfection measures are adopted to block the process of transferring pathogens from an infection source to a susceptible host, so that the occurrence and the cut-off transmission of diseases are prevented, and the diseases are prevented in the bud.
Because the new coronavirus has long survival time under low temperature condition, the imported cold chain food and the external package thereof can become a carrier for the trans-border transmission of the new coronavirus. With the gradual enhancement of national import cold chain food safety management, a traceability management platform is opened at present, the full chain informatization traceability from customs production, wholesale retail sale retail and catering services is basically realized, and the import cold chain management is continuously enhanced.
At present, the low-temperature disinfectant becomes a necessary consumable for disinfection in a low-temperature environment during the normalization of a new crown epidemic situation, and various phenomena appearing in the current market show that the demand of the low-temperature disinfectant is urgent. The low-temperature imported cold chain food disinfection is a new problem, and the point of damage is to manufacture a disinfectant with a disinfection effect under the low-temperature condition. The conventional disinfectant can not achieve the disinfection effect under the low-temperature environment, even the disinfectant freezes after being sprayed, the problem that alcohol is flammable and explosive is further overcome, and the problem of toxicity of the disinfectant is solved. The developed disinfectant can be still sprayed for disinfection and still can keep the disinfection effect when being kept in a liquid state, not solidified and not frozen within the range of minus 40 ℃ to 0 ℃, and can thoroughly solve the propagation problems in the links of production, processing, storage, transportation, circulation, transaction and the like when being used for disinfecting the surfaces of food packages and objects.
The types of the bactericides are various, and the bactericidal effect of the bactericides is influenced by the bactericidal components and the addition amount of the bactericides. Resistance to pests, bacteria, molds, viruses, and the like also affects the bactericidal effect. In the new century, green chemistry has received attention of broad scholars and becomes one of the international scientific research fronts. Therefore, at home and abroad bactericide researchers are focusing on the research and development of ideal bactericides with safety, high efficiency, environmental protection and broad spectrum. Because the ideal bactericide has high research and development cost and great difficulty, researchers mainly research the compounding, synergistic effect, action mechanism and the like of the bactericide at present.
Disclosure of Invention
The invention aims at solving some problems of the current low-temperature disinfectant, develops a low-temperature efficient compound disinfectant in a targeted manner, and aims to provide a low-temperature efficient compound disinfectant which has the advantages of good low-temperature performance, good disinfection effect, no toxicity, environmental protection and low cost.
The quaternary ammonium salt and guanidine disinfectant is a novel environment-friendly disinfectant, has strong sterilization and bacteriostasis performance, broad spectrum, high efficiency, long validity period, no toxic or side effect, no corrosiveness and irritation, safe use, degradability under natural environment, environmental friendliness and no pollution, and is a main component for developing novel disinfectants in recent years.
The quaternary ammonium salt bactericide comprises two types of single-chain (such as benzalkonium chloride and benzalkonium bromide) and double-chain quaternary ammonium salt (such as didecyl dimethyl ammonium chloride and DDAC), one end of the quaternary ammonium salt bactericide is positively charged, and the other end of the quaternary ammonium salt bactericide is a cationic surface active disinfectant, wherein the sterilization mechanism is that the positively charged quaternary ammonium salt unit is adsorbed on the surface of a negatively charged bacterium, and the long-chain alkyl/aryl unit is combined with substances on a cell lipid layer as a lipophilic group to damage the cell wall and cell membrane structure of the bacterium, so that the cell permeability is changed, the substances in the cell are leaked out, the activity of related enzymes is inhibited, and proteins are denatured, so that the bacterium is killed.
Guanidine bactericide includes chlorhexidine acetate, chlorhexidine gluconate, polyhexamethylene monoguanidine, polyhexamethylene biguanide salt derivative, etc., for example, chlorhexidine acetate and chlorhexidine gluconate compound preparation are sold in market. The guanidine sterilization mechanism is similar to that of quaternary ammonium salt, and guanidine with a large number of positive charges can be quickly adsorbed to the surface of bacteria to replace Mg stably existing on the surface of the bacteria2+、Ca2+Mainly interacts with lipopolysaccharide, peptidoglycan components on cell walls and cell plasma membranes, so that the phospholipid environment of the cell membranes is changed, biological dysfunction of the cell membranes is caused, the structure of the cell plasma membranes is damaged, and the microorganism is killed. In addition, polyhexamethylene mono/biguanide (PHMG/PHMB) as a polymer can form a membrane on the surface of the microorganism to close its respiratory tract, thus asphyxiating the bacteria. It is known that single-component bactericidal spectrum is narrow, for example, the dosage of 100% of polyhexamethylene guanidine hydrochloride for the sterilization rate of escherichia coli, staphylococcus aureus and candida albicans is only 200ppm, but the single-component bactericidal spectrum is not suitable for killing cell spores. Such as quaternary ammonium salts, have the same bactericidal activity against pseudomonas aeruginosa, which is common in hospital surgical operating rooms, in addition to polyhexamethylene guanidine hydrochlorideThe bacteria have certain bactericidal capacity, wherein the dosage with the bactericidal rate of 99.999 percent is only 39ppm, but the effect of virus inactivation is weak. Research shows that when the active components are compounded in a certain proportion, the disinfectant has a synergistic effect, and the compounded disinfectant can broaden the bactericidal flora and enhance the bactericidal capacity, and in addition: the compounded disinfectant can effectively reduce the dosage of the disinfectant under the condition of ensuring the sterilization standard, and the purposes of high efficiency, low toxicity, economy and practicability are realized.
