Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gray dye removers, and particularly relates to an o-phthaldehyde disinfectant gray dye remover. BACKGROUND

[0002] Medical devices such as gastrointestinal endoscopes are high-precision equipment, and are limited by manufacturing materials. Conventional medical device disinfection methods such as steam disinfection or ethylene oxide type high-temperature disinfection and sterilization can easily cause problems such as device aging, corrosion, and deformation, and therefore only low-temperature disinfection or sterilization can be selected, that is, high-efficiency chemical disinfectant is used for soaking or flushing disinfection and sterilization.

[0003] At present, the disinfectant for high-level disinfection and sterilization of medical devices mainly includes peroxoacetic acid, hypochlorous acid, glutaraldehyde, and o-phthaldehyde. Among them, peroxoacetic acid and hypochlorous acid are strong oxidizing disinfectants and sterilizing agents, which have the disadvantages of high corrosion and instability; glutaraldehyde is a widely used classic disinfectant and sterilizing agent, which has the characteristics of high volatility and high sensitization, and can easily cause harm to respiratory mucosa and increase the risk of occupational exposure during use; and o-phthaldehyde is a new type of high-efficiency aldehyde disinfectant, which kills microorganisms by cross-linking with proteins in the body of pathogenic microorganisms through aldehyde groups, and has the advantages of low odor and weak irritation compared with traditional glutaraldehyde disinfectant, and has a strong advantage in the field of medical device disinfection, especially in the disinfection of endoscopes.

[0004] The application with the publication number CN116458503A discloses an anti-gray-dye o-phthaldehyde disinfectant, which is composed of the following components in percentage by weight: o-phthaldehyde 0.3-2.0%; modified starch 0.5-5.0%; penetrant 10-25%; complexing agent 0.05-0.50%; corrosion-inhibiting surfactant 0.4-2.5%; pH adjuster 0.25-2.5%; and the balance is purified water. The application also discloses a preparation method of the anti-gray-dye o-phthaldehyde disinfectant. The prepared anti-gray-dye o-phthaldehyde disinfectant can quickly disinfect, has a good effect on mycobacteria, and has good storage stability; can effectively resist the generation of gray dye, and has low corrosion to metal. It is suitable for high-level disinfection of medical devices, especially endoscopes. However, the existing o-phthaldehyde disinfectant has poor stability and a short shelf life because the aldehyde group is in an active state. In addition, relevant applications have found that when the o-phthaldehyde disinfectant is used for disinfection of medical devices such as endoscopes, light gray spots of different shades often appear on the water tank, operating table, skin and work clothes of the operator, and such spots are difficult to clear, which is commonly known as the "gray dye" phenomenon, and can easily affect the service life of the devices, equipment, clothes, and personnel safety. SUMMARY

[0005] Based on the background technology, there are often light gray spots of different shades on the sink, operating table, operating personnel's skin and work clothes, and such spots are difficult to clear, commonly known as "gray dyeing" phenomenon, which easily affects the service life of instruments, equipment, clothes and personnel safety technical problems, the present application provides a kind of o-phthaldehyde disinfectant gray dye remover.

[0006] The o-phthaldehyde disinfectant gray dye remover provided by the application comprises the following raw materials: 10-50 parts of surfactant, 15-40 parts of solvent, 5-10 parts of bleaching agent, 1-5 parts of buffer, 1-5 parts of mildew inhibitor, 1-5 parts of antistatic agent, 1-5 parts of stabilizer, 1-5 parts of adjusting agent and 1-10 parts of water. The surfactant formula is usually designed according to specific use, demand and cleaning effect. The surfactant plays an important role in many cleaners. They improve the wettability, permeability and decontamination ability of the liquid by reducing the surface tension of water. The preparation process of the cleaner usually involves the steps of selecting suitable raw materials, mixing, dissolving, adjusting pH value, thickening and packaging. The buffer (or buffer solution) is a solution used to maintain the pH value of the solution stable. The mildew inhibitor is an additive to prevent the growth of mold. The antistatic agent is a chemical substance used to reduce or eliminate static electricity accumulation. Static electricity is common in many industries and daily life, especially in dry environments. Static electricity can affect the performance of electronic equipment, plastic materials and textiles, and may even cause fire or explosion hazards. The stabilizer is widely used in various products. Its main function is to prevent substances from degrading, reacting or deteriorating during production, storage or use. The adjusting agent (also called adjusting agent or adjusting additive) is a class of chemicals, usually used to adjust or change certain properties or characteristics of products, such as pH, rheology, viscosity, reaction rate, etc.

[0007] Preferably, the surfactant is sodium alkyl benzene sulfonate, polyoxyethylene ether and fatty alcohol polyoxyethylene ether, and the ratio is 2-6:1-5:1-8. The solvent is a mixture of ethanol, isopropyl alcohol and benzene, and the ratio is 1-7:1-8:2-5.

[0008] Preferably, the bleaching agent is a mixture of hydrogen peroxide, sodium percarbonate and citric acid, and the ratio is 2-5:1-7:3-5. The buffer is a mixture of sodium dihydrogen phosphate, sodium carbonate and acetic acid, and the ratio is 1-3:1-5:4-9.

[0009] Preferably, the mildew inhibitor is a mixture of glutaraldehyde, sodium propionate and potassium sorbate, and the ratio is 1-9:1-8:1-7. The antistatic agent is a mixture of aluminum sulfate, sodium chloride and glycerol, and the ratio is 2-6:2-9:1-4.

[0010] Preferably, the stabilizer is prepared by mixing sorbitan, glycerol and phenoxyethanol in a ratio of 1-2:2-4:1-2, and the adjusting agent is prepared by mixing citric acid, sodium hydroxide and acetic acid in a ratio of 1-5:2-7:4-8.

[0011] Preferably, the solvent and water are first added to the inside of the blender for heating, the inside of the blender is heated to 30-55 degrees Celsius, then the surfactant is added, the rotation speed is raised to 150-180 revolutions per minute, and the mixture is stirred for 5-10 minutes.

[0012] Preferably, then the adjusting agent is added to the inside of the blender, and stirred for 1-5 minutes.

[0013] Preferably, finally the bleaching agent, buffer, mildew inhibitor, antistatic agent and stabilizer are added to the inside of the blender, and stirred for 10-15 minutes to prepare the o-phthalaldehyde disinfectant gray dye remover.

[0014] Advantages of the present application: The present application is targeted, specifically for pollutants such as dyes and pigments, can quickly penetrate and decompose dye molecules, without damaging the fibers of the fabric itself, has strong decontamination ability, can quickly decompose and remove stains caused by gray dyeing, color pollution, etc., and restore the cleanliness of the fabric or surface.
