Water-based cleaning agent with weak acidity for removing thick oil dirt, and preparation method thereof

Abstract

The invention discloses a water-based cleaning agent with weak acidity for removing thick oil dirt, and a preparation method thereof. The water-based cleaning agent is suitable for dinning places of kitchens, restaurants, snack streets and the like. The formula of the water-based cleaning agent is prepared from the following components by weight percent: 2.0-9.6% of alkyl glycoside, 2.0-4.0% of fatty alcohol polyoxyethylene ether sodium sulfate, 2.4-6.8% of coconut oleic acid amide propyl betaine, 0.6-2.0% of sulfonated succinate dioctyl ester sodium salt and the balance of running water. The preparation method of the cleaning agent comprises the following steps of: firstly, weighing the materials according to the ratio, and then putting into a same container to agitate for about 1 hour until a clear transparent solution is formed. The water-based cleaning agent is cheap and available in materials; biodegradation is facilitated; no organic solvent or acid-base is added; the solvent is running water; the formula and the preparation technology are simple; the pH value of the homemade cleaning agent is about 6.5; and the cleaning agent is weak acidic, and is a little different from the traditional mainstream cleaner which is alkaline. Thus, the water-based cleaning agent is an economic and applicable neutral water-based cleaning agent.

Description

technical field [0001] The present invention relates to the preparation of a cleaning agent, in particular to a raw material that is cheap, easy to obtain, and biodegradable for the removal of thick oily dirt in kitchens, restaurants, snack streets and other dining places, without adding any organic solvents and acids and bases. The solvent is Tap water, a weakly acidic water-based cleaning agent with simple formula and preparation process and a preparation method thereof. Background technique [0002] Generally speaking, the methods of removing oil stains can be roughly divided into three categories: the first category is organic solvent degreasing, its main advantages are high degreasing efficiency and single raw material, and the disadvantages are that organic solvents are generally toxic, have low flash point, and are flammable Explosive, easy to cause pollution to the environment. The second type is strong alkali degreasing, which is mainly cleaned by soaking and spray...

[0002] Generally speaking, the methods of removing oil stains can be roughly divided into three categories: the first category is organic solvent degreasing, its main advantages are high degreasing efficiency and single raw material, and the disadvantages are that organic solvents are generally toxic, have low flash point, and are flammable Explosive, easy to cause pollution to the environment

The second type is strong alkali degreasing, which is mainly cleaned by soaking and spraying. Its advantages are low price, easy to obtain raw materials, and strong ability to remove heavy oil stains. The disadvantage is that strong alkali has a large corrosion on the user's skin. sex

In recent years, various cleaning agents for oil stain cleaning have been developed and applied one after another. However, due to reasons such as the selection of surfactants and the unreasonable formula structure, the cleaning effect on thick oil stains or the environmental friendliness of the adopted formula are still difficult to achieve. satisfactory

For example, CN102888298A discloses a "cleaning agent for range hoods". The developed cleaning agent has excellent effects and has no corrosion or scratching effect on range hoods. However, the formula contains trisodium phosphate and highly volatile , toxic acetone, there are certain safety hazards

CN10146329A discloses "a super-concentrated quick cleaning agent for oil stains and its production method". The developed cleaning agent can be used for quick cleaning of heavy oil stains, but the formula is added with strong alkali NaOH, which is not only highly corrosive, but also easily causes environmental pollution , which limits its use

CN1916143A discloses "an airport pavement greasy cleaning agent and its preparation method". The developed cleaning agent can be used to clean all kinds of greasy dirt on the runway, but the formula contains potassium pyrophosphate which can cause eutrophication of the water body and is harmful to the eyes. Triethanolamine, a weak organic base that is irritating and slightly harmful to water

For another example, CN103045401A discloses "a water-based heavy oil dirt cleaning agent and preparation method thereof", and the developed cleaning agent can quickly remove heavy oil dirt on the road surface, but the cleaning agent is composed of cocamidopropyl betaine, fatty alcohol Composed of 8 ingredients including polyoxyethylene ether, sulfonate of fatty acid methyl ester ethoxylate, sodium α-olefin sulfonate, sodium dodecylbenzene sulfonate, triethanolamine, trisodium citrate and tap water, the formula more complex
