Description

[0001] The application belongs to the technical field of disinfectants, and particularly relates to a high-efficiency environment-friendly potassium peroxymonosulfate composite salt disinfectant as well as a preparation method and application thereof. BACKGROUND

[0002] There are various disinfectants on the market, such as sodium hypochlorite, chlorinated isocyanuric acid, halogenated hydrazine, iodine preparation, quaternary ammonium salt, formaldehyde, glutaraldehyde, composite phenol and chlorine dioxide, each of which has advantages and disadvantages in terms of sterilization effect, safety, sterilization persistence and use convenience, and there is an urgent need for an excellent disinfectant with excellent sterilization and disinfection effect, convenient use, small side effects and corrosion to meet the disinfection needs of modern people. The present study develops a green disinfectant product with rapid, high, persistent and broad-spectrum effects, which is a strong demand on the market.

[0003] Chinese patents CN105394081A, CN106973939A, CN107624785A, CN110622993A and CN108902174A are all disinfectants with potassium peroxymonosulfate as the main disinfecting component, and organic acid is added to provide an acidic environment to make the potassium peroxymonosulfate composite salt undergo a cyclic chain reaction, and the cyclic reaction continuously produces effective sterilization substances. Such disinfectants have strong corrosion due to their strong oxidizing and acidic properties, which can cause serious damage to the objects to be disinfected. Therefore, it is of great practical significance to develop an environmental surface disinfectant with low corrosion.

[0004] At the same time, many disinfectants, such as peroxoacetic acid disinfectants, produce a large amount of irritating odor during the disinfection process, which is difficult to offset. The operator needs to do a good job in comprehensive protection during the disinfection process, which brings many inconveniences to the use of disinfectants. Therefore, it is particularly important to select green disinfecting ingredients without irritation, which simplifies the operation and solves the safety problem of disinfectants from the source. In summary, it is the trend to develop a disinfectant with strong disinfection capacity, stability, high efficiency, corrosion inhibition, safety and environmental protection. SUMMARY

[0005] The main purpose of the present application is to overcome the shortcomings of the existing potassium peroxymonosulfate composite salt disinfectant, and to provide a broad-spectrum, high-efficiency, corrosion-inhibiting, green and safe compound disinfectant without irritation to humans and animals.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: The application discloses a high-efficiency environment-friendly potassium peroxymonosulfate composite salt disinfectant which comprises the following raw materials in parts by weight: 70-90% of potassium peroxymonosulfate composite salt, 0.1-5% of a surfactant, 0.1-6% of an organic activator, 0.1-5% of a pH buffer, 0.01-0.25% of an indicator, 0.1-1% of a carbon meso quantum dot corrosion inhibitor, 2-8% of a chelating agent, 0.1-5% of a synergist and 0.1-5% of an antifreezing agent.

[0007] Preferably, the organic acid is at least one of sulfamic acid and citric acid.

[0008] Preferably, the synergist is at least one of sodium chloride and potassium chloride.

[0009] Preferably, the pH buffer is at least one of malic acid and succinic acid.

[0010] Preferably, the surfactant is at least one of sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, sodium secondary alkyl benzene sulfonate and cetyltrimethylammonium bromide.

[0011] Preferably, the chelating agent is at least one of sodium tripolyphosphate, sodium hexametaphosphate, trisodium phosphate, anhydrous sodium pyrophosphate and EDTA-2Na.

[0012] Preferably, the indicator is at least one of amaranth, carmine and middle red.

[0013] Preferably, the carbon meso quantum dot corrosion inhibitor is a corrosion inhibitor developed by a company and synthesized from glucose and thiourea.

[0014] Preferably, the antifreezing agent is at least one of calcium chloride and magnesium chloride.

[0015] The application has the following working principle: different microorganisms have certain differences in sensitivity to disinfectants, among which bacteria spores have the strongest resistance to disinfectants; potassium peroxymonosulfate composite powder can continuously and durably produce small molecule free radicals, hypochlorous acid, nascent oxygen and active oxygen derivatives in water through a chain reaction, oxidizes and chlorinates pathogens, makes pathogen proteins denature and coagulate, and the produced -OH free radicals act on the phosphodiester bonds of DNA and RNA, thereby interfering with the synthesis of pathogen DNA and RNA and killing pathogenic microorganisms; in the chain reaction path, sodium chloride is oxidized by potassium peroxymonosulfate triple salt compound, the generated chlorine gas does not release but interacts with sulfamic acid (as a chlorine acceptor) to form an intermediate complex, then the complex is decomposed to generate hypochlorous acid, meanwhile, the reaction is cyclic, and the chlorine released from the sulfamic acid is used to form more sodium chloride molecules, thereby providing the cycle with continuous raw materials; in the reaction process, H +The acid preparation can play a disinfection effect, the intermediate product Cl2 and ClO can play a role of halogen disinfectant, and can play a role of peroxide disinfectant by releasing O2 free radicals.

[0016] Compared with the prior art, the technical scheme provided by the application has the following beneficial effects: The potassium hydrogen persulfate composite salt disinfection principle is a cyclic chain reaction, and the potassium hydrogen persulfate composite salt, organic activator, synergist and water participating in the chain reaction continuously generate effective bactericidal substances, so that the potassium hydrogen persulfate composite salt disinfectant can effectively maintain the bactericidal ability for a long time, and the disinfection and sterilization effect is ensured.

[0017] The lemon essence is added, the disinfectant has a pleasant lemon fragrance and is not irritating to the human body, and also has the effect of assisting disinfection and sterilization, and truly realizes green and safe disinfection.

[0018] The potassium hydrogen persulfate is a neutral salt, and the acidity of the aqueous solution is caused by hydrogen ions generated by the dissolution of potassium hydrogen sulfate in the composite salt. However, the stability of the potassium hydrogen persulfate under acidic conditions is much better than that under neutral conditions, and the potassium hydrogen persulfate is quickly decomposed under alkaline conditions. The strong acidity leads to strong corrosiveness, and the carbon quantum dot corrosion inhibitor of the company is added in the application, so that the corrosion of the disinfectant to various metals can be effectively resisted.

[0019] The application prepares a high-efficiency environmental protection disinfectant with a wide bactericidal spectrum, green safety, low corrosion, good stability, long bactericidal duration, and small irritation through the synergistic effect of various components.
