Description

Technical Field

[0001] The present invention belongs to the technical field of disinfectants, and particularly relates to a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, a preparation method thereof, and an application thereof. Background Art

[0002] As one of the effective methods to block the transmission route of infectious diseases, disinfectants can kill or remove pathogenic microorganisms in the external environment, thereby cutting off the transmission of pathogens. Compared with foreign countries, the environment of farms in China is relatively poor, and there are problems such as relatively single types of disinfectants, narrow bactericidal spectra of single-component disinfectants, or strong irritation.

[0003] Glutaraldehyde is a commonly used high-efficiency disinfectant. It mainly achieves the effect of killing bacteria and viruses by alkylating microbial proteins, sealing the outer layer of bacteria, inactivating cellular enzymes, and changing the nucleic acid-protein structure. Moreover, it has less corrosion to metal instruments, glass, and plastic products. Quaternary ammonium salt compounds are also a commonly used disinfectant component, which can change the permeability of the bacterial cell membrane, cause the components inside the cell to leak out, and hinder cell metabolism, thereby causing the death of bacteria.

[0004] Studies have shown that glutaraldehyde quaternary ammonium salt compound disinfectants cause the death of Escherichia coli by destroying the cell wall and cytoplasmic membrane. The main reason is that they change the biochemical properties of the phospholipid bilayer in the cell membrane. The bactericidal efficiency of quaternary ammonium salt disinfectants is also different at different concentrations. At lower concentrations, they play an antibacterial role, and at higher concentrations, they can effectively kill viruses. They mainly exert their effects on enveloped viruses such as ASFV through their hydrophobic activity. Decamethonium chloride can kill viruses, bacteria and other microorganisms, while benzalkonium bromide, a low-efficiency disinfectant, can only kill lipophilic viruses and bacteria, but neither can kill bacterial spores. However, after compounding single-chain and double-chain quaternary ammonium salts, not only can the bactericidal spectrum of low-efficiency disinfectants be effectively expanded, but also the disinfection effect can be enhanced.

[0005] At present, there are few varieties of glutaraldehyde quaternary ammonium salt disinfectants in the domestic market. The effect of killing microbial viruses is average, and there is no product that can simultaneously perform the functions of cleaning and disinfection, which cannot meet the prevention and control of diseases in the current increasing number of large-scale intensive farms. Moreover, affected by the swine fever epidemic, the future aquaculture industry will increase the demand for disinfectants. Therefore, it is an inevitable trend to provide a disinfectant that can not only ensure high-efficiency and wide-spectrum bactericidal effects, but also has characteristics such as safety, low toxicity, and integration of cleaning. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, its preparation method and application. The present invention optimizes the raw material composition ratio of the glutaraldehyde quaternary ammonium salt disinfectant to achieve the goal of strengthening the disinfection effect of the glutaraldehyde quaternary ammonium salt and endowing it with a washing and cleaning function. Using the disinfectant of the present invention to disinfect metal utensils and the surrounding metal environment can effectively ensure the integrity and durability of metal facilities during the disinfection process.

[0009] The present invention provides a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, which comprises the following raw materials in parts by mass: 10 parts of glutaraldehyde, 5 parts of decamethonium chloride, 5 parts of benzalkonium bromide, 10 parts of benzalkonium chloride, 3 parts of surfactant, 6 parts of emulsifier, 1.1 parts of stabilizer, 0.1 part of carbon quantum dot corrosion inhibitor, and 59.8 parts of water.

[0010] The present invention provides a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, which comprises the following raw materials in parts by mass: 8 parts of glutaraldehyde, 5 parts of decamethonium chloride, 5 parts of benzalkonium bromide, 5 parts of benzalkonium chloride, 7 parts of surfactant, 7 parts of emulsifier, 1.2 parts of stabilizer, 0.1 part of carbon quantum dot corrosion inhibitor, and 61.7 parts of water.

[0011] The present invention provides a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, which comprises the following raw materials in parts by mass: 10 parts of glutaraldehyde, 6 parts of decamethonium chloride, 8 parts of benzalkonium bromide, 5 parts of benzalkonium chloride, 8 parts of surfactant, 6 parts of emulsifier, 1.2 parts of stabilizer, 0.1 part of carbon quantum dot corrosion inhibitor, and 55.7 parts of water.

[0012] Preferably, the emulsifier comprises one or more of sorbitan fatty acid, polysorbate, poloxamer, fatty alcohol polyoxyethylene, lauryl alcohol polyoxyethylene ether, and isooctyl polyoxyethylene ether.

[0013] Preferably, the surfactant comprises at least one of sodium dodecyl sulfate and modified silicone resin polyoxyethylene ether.

[0014] Preferably, the stabilizer comprises one or more of isovaleric acid, isopentyl acetate, branched dodecylphenol, ethylene glycol monophenyl ether, and fatty alcohol polyethylene glycol ether.

[0015] The present invention also provides a method for preparing the above-mentioned glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, which includes the following steps:

[0016] 1) Mix decamethonium chloride, benzalkonium bromide, benzalkonium chloride with water to obtain a first mixed solution;

[0017] 2) Mix the first mixed solution obtained in step 1) with glutaraldehyde to obtain a second mixed solution;

[0018] 3) Mix the second mixed solution obtained in step 2) with an emulsifier to obtain a third mixed solution;

[0019] 4) Mix the third mixed solution obtained in step 3) with a surfactant to obtain a fourth mixed solution;

[0020] 5) Mix the fourth mixed solution obtained in step 4) with a stabilizer to obtain a fifth mixed solution;

[0021] 6) Mix the fifth mixed solution obtained in step 5) with a carbon quantum dot corrosion inhibitor to obtain the glutaraldehyde quaternary ammonium salt foam cleaning disinfectant.

[0022] The present invention also provides the application of the above-mentioned glutaraldehyde quaternary ammonium salt foam cleaning disinfectant in the disinfection of farms.

[0023] The present invention also provides the application of the above-mentioned glutaraldehyde quaternary ammonium salt foam cleaning disinfectant in the disinfection of metal utensils or metal environments.

[0024] The beneficial technical effects of the present invention are as follows:

[0025] 1. The present invention adds a surfactant and an emulsifier. The emulsifier is a surfactant such as fatty alcohol polyoxyethylene and lauryl alcohol polyoxyethylene ether, which can improve the stability of the foam of the glutaraldehyde quaternary ammonium salt disinfectant, enhance the cleaning effect and maintain its effectiveness; the surfactant is sodium dodecyl sulfate and a modified silicone resin polyoxyethylene ether emulsifier, which plays the role of foaming and wall hanging, and decontamination and cleaning.

[0026] 2. The present invention improves the bactericidal ability through the compound synergistic effect of the quaternary ammonium salts and glutaraldehyde of each component. Generally, a single quaternary ammonium salt cannot kill bacterial spores, but adding a low concentration of aldehyde disinfectant can have the ability to kill spores.

[0027] 3. The present invention adds a cationic surfactant, which can improve the stability. Adding a cationic surfactant to the compound disinfectant can play a certain role in improving the stability of the compound disinfectant containing glutaraldehyde, and at the same time can also improve the bactericidal effect of glutaraldehyde; it also has the advantages of decontamination and cleaning, easy transportation and storage.

[0028] 4. The compound disinfectant has added a foaming disinfection method. After the disinfectant is dissolved in water, it is used in conjunction with a foaming gun to produce delicate and visible foam, which increases the time of attachment to the surface of the disinfection object. When disinfecting instruments and breeding farm cages, the surface residence time is longer, making the disinfection more thorough. Compared with low-foaming disinfectant solutions of the same concentration, the disinfection effect is better.

[0029] 5. The carbon quantum dot corrosion inhibitor in carbon can effectively resist the corrosion of various metals by the disinfectant. The carbon quantum dot corrosion inhibitor in carbon interacts with surfactants such as sodium dodecyl sulfate, and can jointly cover the metal surface to form a protective film to resist the corrosion of strongly oxidizing, acidic and high-concentration anion solutions. Detailed implementation mode

[0030] The present invention provides a glutaraldehyde quaternary ammonium salt foam cleaning disinfectant, which comprises the following raw materials in parts by mass: 5-20 parts of glutaraldehyde, 5-10 parts of decamethonium chloride, 5-10 parts of benzalkonium bromide, 5-10 parts of benzalkonium chloride, 5-15 parts of surfactant, 5-15 parts of emulsifier, 1-3 parts of stabilizer, 0.1-1 part of carbon quantum dot corrosion inhibitor in carbon, and 16-63.9 parts of water.

[0031] The present invention has no special limitation on the source of the raw materials, and conventional commercially available products in the art can be used.

[0032] In the present invention, the emulsifier preferably includes one or more of sorbitan fatty acid, polysorbate, poloxamer, fatty alcohol polyoxyethylene, lauryl alcohol polyoxyethylene ether, and isooctyl polyoxyethylene ether.

[0033] In the present invention, the surfactant preferably includes at least one of sodium dodecyl sulfate and modified silicone resin polyoxyethylene ether.

[0034] In the present invention, the stabilizer preferably includes one or more of isovaleric acid, isopentyl acetate, branched dodecylphenol, ethylene glycol monophenyl ether, and fatty alcohol polyethylene glycol ether.

[0035] In the present invention, the carbon quantum dot corrosion inhibitor in carbon is synthesized with glucose and thiourea as raw materials. The preparation method of the carbon quantum dot corrosion inhibitor in carbon is as follows: Take the mass ratio of glucose and thiourea (2:1), then dissolve it in distilled water and stir to form a clear aqueous solution. The obtained solution is ultrasonicated for 30-60 minutes and then placed in a microwave oven and heated for 10-30 minutes. After the brown solid is cooled to room temperature, it is dissolved in distilled water to form a black-brown solution. In a centrifuge, it is centrifuged for 10-30 minutes, and the supernatant is taken. The supernatant is subjected to vacuum drying and separation to obtain a filtrate and a filter residue. The filtrate is vacuum dried at 70°C for 10-20 hours to obtain the carbon quantum dot corrosion inhibitor in carbon.
