Problems solved by technology

[0004] Chlorine-containing disinfectant can effectively kill common bacteria such as Escherichia coli, Staphylococcus aureus, and Candida albicans. It is safe and reliable, but because sodium hypochlorite, an active ingredient of chlorine-containing disinfectant, is easily decomposed and ineffective under the induction of light, heat, acid, and heavy metals, the thermal stability of chlorine-containing disinfectant is poor, and the shelf life is short. production and storage difficulties

preparation example Construction

[0040] Further, the present invention also proposes a method for preparing a chlorine-containing disinfectant with high thermal stability, for preparing the above-mentioned chlorine-containing disinfectant with high thermal stability, comprising the following steps:

[0041] S1) in sodium hypochlorite solution, add pH value regulator, adjust the pH value of sodium hypochlorite solution to be 11.5-12.5;

[0042] S2) adding stabilizer, chelating agent and surfactant to the sodium hypochlorite solution processed in step S1) successively and stirring, and after stirring, it is cooled to room temperature to obtain the chlorine-containing disinfectant.

[0043] The production process is simple and the manufacturing cost is low.

[0044] Preferably, in step S1), the temperature of the sodium hypochlorite solution is not higher than 30°C.

[0045] If the temperature of the sodium hypochlorite solution is higher than 30°C, it will generate heat when the sodium hydroxide solution is ad...

Embodiment 1-5 and comparative example 1-4

[0049] 1. The chlorine-containing disinfectant of each embodiment and each comparative example is prepared according to the following steps:

[0050] S1) in the sodium hypochlorite solution, add a pH value regulator, and adjust the pH value of the sodium hypochlorite solution to be 11.5-12.5;

[0051]S2) successively add stabilizer, chelating agent and surfactant to the sodium hypochlorite solution processed in step S1) and stir, and after stirring, be cooled to room temperature to obtain the chlorine-containing disinfectant;

[0052] In step S1), the temperature of sodium hypochlorite solution is not higher than 30 ℃;

[0053] In step S1), the pH adjusting agent is sodium hydroxide solution, the concentration of the sodium hydroxide solution is not higher than 15wt%, and the temperature of the sodium hydroxide solution is not higher than 25°C.

[0054] 2. See Table 1 for the raw material composition, ratio and process parameters of each embodiment and comparative example.

Abstract

The invention relates to the technical field of disinfectant fluid, and discloses a chlorine-containing disinfectant with high thermal stability. The disinfectant comprises the following raw materials by mass concentration: 180-200 g/l of sodium hypochlorite, 3-7 g/l of a stabilizer, 2-4 g/l of a chelating agent and 2-5 g/l of a surfactant. The stabilizer is one of potassium chlorate, sodium phosphate, sodium silicate and potassium bromide; the chelating agent is at least one of alkyl alcohol polyoxyethylene ether and isopentenol polyoxyethylene ether; and the surfactant is one of sodium dodecyl benzene sulfonate, fatty alcohol polyoxyethylene ether sodium sulfate, dodecyl alcohol sodium sulfate and dodecyl amphoteric betaine, and has lower thermal decomposition efficiency, so that the shelf life is longer. The invention further provides a preparation method of the chlorine-containing disinfectant with high thermal stability. The process is simple and effective, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a chlorine-containing disinfectant with high thermal stability and a preparation method thereof. Background technique [0002] Disinfectants include ethanol disinfectant, glutaraldehyde-based disinfectant, sodium hypochlorite-based chlorine-containing disinfectant, bleaching powder and bleaching powder-based disinfectant, etc. Products that kill bacteria and viruses, prevent disease and inhibit the spread of viruses. [0003] Chlorine-containing disinfectant is widely popular because of its low price, good sterilization effect and high safety. It has become a widely used popular consumer product, which has promoted the development and production of disinfection products. [0004] Chlorine-containing disinfectant can effectively kill common bacteria such as Escherichia coli, Staphylococcus aureus, and Candida albicans. Under the specified concentration, it is safe and relia...
