Novel disinfectant and preparation method thereof

Abstract

The invention discloses a novel disinfectant and a preparation method thereof, and relates to the technical field of disinfectants. The disinfectant is prepared from the following components in percentage by mass: 1.5%-4.5% of a sterilizing agent, 0.5%-1.5% of glutaraldehyde, 0.5%-2.5% of aniline phenol, 20%-40% of ethanol, 2%-4% of sodium hydroxide, 0.2%-1.3% of sodium hypochlorite, 3.5%-6% of asurfactant and the balance of water. The disinfectant is prepared by mixing the above materials in proportion and has the characteristics of wide bactericidal spectrum, strong bactericidal ability, high action speed, good stability, low toxicity, low corrosivity, low irritation (no toxicity, no residue, no corrosion and no irritation), easiness in dissolving in water, safety to human and animals,low price, easiness in obtaining, low environmental pollution degree and the like; meanwhile, the disinfectant has relatively strong decontamination stability, is simple in use method and is suitablefor disinfection of various environments.

Description

technical field [0001] The invention relates to the technical field of disinfectant, in particular to a novel disinfectant and a preparation method thereof. Background technique [0002] The common disinfectants on the market mainly include the following types: the main components are triclosan, chlorhexidine, o-phenylphenol, trichloroisocyanuric acid, sodium hypochlorite, etc., which are generally chlorine that is harmful to the human body and the environment. , phenolic compounds; ethanol disinfectant has a strong irritation to the skin, which can cause a tingling sensation to the wound and is easy to cause fire; aldehyde disinfectant, such as glutaraldehyde disinfectant, has a strong pungent smell and is harmful to the skin and mucous membranes. It has a strong stimulating effect and can make the skin yellow and peel; peroxide disinfectants such as peracetic acid and hydrogen peroxide have a strong pungent odor and are volatile, and the presence of organic matter can redu...

[0002] The common disinfectants on the market mainly include the following types: the main components are triclosan, chlorhexidine, o-phenylphenol, trichloroisocyanuric acid, sodium hypochlorite, etc., which are generally chlorine that is harmful to the human body and the environment. , phenolic compounds; ethanol disinfectant has a strong irritation to the skin, which can cause a tingling sensation to the wound and is easy to cause fire; aldehyde disinfectant, such as glutaraldehyde disinfectant, has a strong pungent smell and is harmful to the skin and mucous membranes. It has a strong stimulating effect and can make the skin yellow and peel; peroxide disinfectants such as peracetic acid and hydrogen peroxide have a strong pungent odor and are volatile, and the presence of organic matter can reduce its bactericidal effect; iodine-containing disinfection Liquids mainly include iodine, iodophor, etc. This type of disinfectant has a broad spectrum of sterilization and has a certain killing effect on spores, but requires a higher content. When organic matter exists, the effectiveness is weakened and it is easy to see light decomposition; quaternary ammonium salt disinfectant It belongs to cationic surfactant disinfectant, low concentration required for sterilization, non-irritating, colorless and tasteless, non-corrosive, non-bleaching, good solubility, convenient to use, stable in nature, but not effective for some microorganisms and cannot be killed Microorganisms such as fungi, Mycobacterium tuberculosis, viruses and spores; more expensive, more incompatibility, bactericidal effect is greatly affected by organic matter, sensitive to metal ions such as calcium and magnesium, and metal ions such as calcium and magnesium are easy to form activity with quaternary ammonium salt cations Quaternary ammonium salt compounds with lower solubility and lower bactericidal activity of quaternary ammonium salt disinfectants
