[0003] However, although the above-mentioned various disinfectants can kill bacteria and viruses, they have toxic side effects, are dangerous during use, and have different degrees of impact on the ecological environment
For example, chlorine-containing disinfectants and peracetic acid disinfectants can kill bacteria and viruses, but they are far more corrosive to the surface of metal objects than other products, and can seriously fade colored clothes; alcohol-based disinfectants can kill bacteria and viruses , but in case of open fire and high temperature, it is flammable and ex

Example Embodiment
[0028]The present invention provides a preparation method of the quaternary ammonium salt compound disinfectant described in the above technical scheme, which includes the following steps:
[0029]Mixing water, coconut oil fatty alcohol diethanolamide and glycerol to obtain a mixed liquid;
[0030]The mixed solution, benzalkonium chloride and polyhexamethylene biguanide are mixed, the pH value is adjusted to 5.5-7.5, and the mixture is filtered to obtain a quaternary ammonium salt compound disinfectant.
[0031]In the present invention, water, coconut oil fatty alcohol diethanolamide and glycerol are mixed to obtain a mixed liquid. In the present invention, the process of mixing the water, coconut oil fatty alcohol diethanolamide and glycerol is not particularly limited, and the raw materials can be uniformly mixed according to a process well known in the art.
[0032]After the mixed solution is obtained, the present invention mixes the mixed solution, benzalkonium chloride and polyhexamethylen...
Example Embodiment
[0039]Example 1
[0040]The components of the quaternary ammonium compound disinfectant are: benzalkonium chloride 0.1%, polyhexamethylene biguanide 0.02%, coconut oil fatty acid diethanolamide 0.2%, glycerol 0.2%, and the balance of deionized water.
[0041]The preparation method is:
[0042]Add deionized water, coconut oil fatty alcohol diethanolamide and glycerol in proportions and stir evenly to obtain a mixed solution;
[0043]Add benzalkonium chloride and polyhexamethylene biguanide to the mixed solution in proportion, stir evenly, adjust the pH to 6.0, after filtering, test the resulting liquid phase, and those who pass the test are the quaternary ammonium compound disinfection liquid.

Abstract
The invention provides a quaternary ammonium salt compound disinfectant and a preparation method thereof, which belong to the technical field of disinfectants. A compound synergistic principle is adopted, benzalkonium chloride and polyhexamethylene biguanide which belong to the same cationic surfactant are compounded into a compound disinfectant, strong electropositivity is generated by ionizationin an aqueous solution, bacteria and viruses with negative charges can be adsorbed, and coconut oil fatty acid diethanolamide and glycerol are cooperatively used, positive charges ionized by benzalkonium chloride and polyhexamethylene biguanide are promoted to penetrate through cell walls, so that bacteria and viruses can be killed, and great danger to the safety of people and influence on the environment are avoided. The quaternary ammonium salt compound disinfectant provided by the invention has the advantages of easily available raw materials, easily operated preparation process, low production cost, no corrosion to human and object surfaces, no odor, no toxicity, environmental protection and convenient use, and is an ideal disinfectant.
Description
technical field [0001] The invention relates to the technical field of disinfectants, in particular to a quaternary ammonium salt compound disinfectant and a preparation method thereof. Background technique [0002] At present, the demand for disinfection products has exploded. Chlorine disinfectants, alcohol disinfectants, peroxide disinfectants, aldehyde disinfectants, quaternary ammonium salt disinfectants, iodine disinfectants, phenol disinfectants and Guanidine disinfectants are widely used. [0003] However, although the above-mentioned various disinfectants can kill bacteria and viruses, they have toxic side effects, are dangerous during use, and have different degrees of impact on the ecological environment. For example, chlorine-containing disinfectants and peracetic acid disinfectants can kill bacteria and viruses, but they are far more corrosive to the surface of metal objects than other products, and can seriously fade colored clothes; alcohol-based disinfectant...
