Abstract

The invention discloses a quaternary ammonium salt disinfection solution, and a preparation method and application thereof. The quaternary ammonium salt disinfection solution comprises the following components: hexamethylenetetramine, benzalkonium bromide, benzalkonium chloride, polyhexamethylene guanidine, Tween 80, octadecyldimethylbenzyl chloride, isopropanol and sterile water. The invention further discloses a method for preparing the disinfection solution. According to the invention, hexamethylenetetramine, benzalkonium bromide, benzalkonium chloride, polyhexamethylene guanidine, octadecyldimethylbenzyl chloride and Tween 80 are combined together according to a specific mixing proportion, and the components have synergistic effects, so a variety of disadvantages of a single disinfectant variety or a simply-mixed disinfectant are overcome, and a variety of bacteria, fungi, spores and viruses can be thoroughly killed; meanwhile, the disinfection solution is safe to human body, is free of toxicity and stimulation, is convenient to use, can be directly used by being diluted with water, realizes one-step completion of disinfection and cleaning, has no corrosion to equipment and no harm on the environment, and is biodegradable.

Description

Technical field [0001] The invention relates to a disinfectant, in particular to a compound quaternary ammonium salt disinfectant and a preparation method thereof. The invention further relates to the application of the compound quaternary ammonium salt disinfectant in disinfection and cleaning, and belongs to compound quaternary ammonium salt The field of disinfectant. Background technique [0002] Most of the current disinfection products and cleaning products are used alone, although the disinfection and cleaning effects can be guaranteed, not only the operation and use steps are cumbersome, but also there are various deficiencies in varying degrees: [0003] The most commonly used disinfectants are mostly chlorine, bromine, iodine or the corresponding halogen-releasing compounds. The largest amount of this kind of disinfectant is chlorine. Because the raw materials are easily available, easy to prepare, cheap, and reliable in sterilization, it is widely used; but this kind of ...
