Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the disadvantages of poor removal ability of old viscous oil stains by cleaning agents made from surfactants at present, a method is provided to dry the picked fresh tobacco leaves and smoke them with sulfur powder Roast the tobacco leaves until they turn yellow, then burn them, collect the tobacco oil and put it into a Soxhlet extractor, extract it with ethanol, concentrate the extract, mix it with a surfactant, centrifuge to obtain the supernatant, and then add The obtained smoke oil is stirred to make it fully dissolved, and then extracted with ether, the extract is concentrated and then mixed with a surfactant again, and then centrifuged to prepare a water-based oil cleaning agent, in order to strengthen the old viscous The purpose of degreasing ability

example 1

[0018] First pick 2kg of fresh tobacco leaves, rinse them lightly with water twice to remove stains and impurities, and then put them in the sun for drying. After drying, put them in the smoking barn, and then send them to the smoking barn. Into the tobacco leaf mass 3% sulfur powder is fully smoked and roasted; then after the tobacco leaves are smoked and roasted to a yellow color, stop smoking and roasting, take them out and burn them, collect the burned tobacco oil, and put them in the cable At the same time, add 1% ethanol of e-liquid mass into it in a conventional extractor, set the temperature to 85°C, and extract for 18 hours; after the above extraction is completed, place the extract in a rotary evaporator for concentration for 2 hours. After the concentration is completed, add fatty alcohol polyoxyethylene ether sodium sulfate, sodium lauryl sulfate and the mass ratio of 1:1:10 to the concentrated solution. In the concentrated solution, control the temperature to 70°C,...

example 2

[0021] First pick 2.5kg of fresh tobacco leaves, rinse them lightly with water for 3 times to remove stains and impurities, and then put them in the sun for drying. After drying, put them in a smoking barn, and then grill them. Put 4% sulfur powder of the tobacco leaf mass into the room to fully smoke and roast it; then, after the tobacco leaf is smoked and roasted until the color turns yellow, stop smoking and roasting, take it out and burn it, collect the burned smoke oil, and put it in At the same time, add 2% ethanol of e-liquid mass into the Soxhlet extractor, set the temperature at 88℃, and extract for 19 hours; after the above extraction is completed, place the extract in a rotary evaporator for concentration 2.5 h. After the concentration is completed, according to the mass ratio of fatty alcohol polyoxyethylene ether sodium sulfate, sodium lauryl sulfate and concentrated solution 1:1:10, the fatty alcohol polyoxyethylene ether sodium sulfate and sodium lauryl sulfate A...

example 3

[0024] First pick 3kg of fresh tobacco leaves, rinse them lightly with water for 3 times to remove stains and impurities, and then put them in the sun for drying. After drying, put them in the smoking barn, and then to the smoking barn. Into the tobacco leaf mass 5% sulfur powder to fully smoke and roast it; then after the tobacco leaf is smoked and roasted until the color is yellow, stop smoking and roasting, take it out and burn it, collect the burned tobacco oil, and put it in the cable At the same time, add 3% ethanol of the e-liquid mass into the extractor, set the temperature to 90℃, and extract for 20 hours; after the above extraction is completed, put the extract in a rotary evaporator for concentration for 3 hours, After the concentration is completed, add fatty alcohol polyoxyethylene ether sodium sulfate, sodium lauryl sulfate at a mass ratio of 1:1:10 to the concentrated solution. In the concentrated solution, control the temperature to 80°C, stir at a speed of 500r...

Abstract

The invention discloses a method for preparing a water-based oil stain cleaning agent and belongs to the field of cleaning agent preparation. The method comprises the steps of drying picked fresh tobacco leaves in the sun, conducting fire-curing on the tobacco leaves with sulphur powder till the tobacco leaves get yellowed, then burning the tobacco leaves, collecting and placing tobacco tar into a cable type extractor, conducting extraction with ethyl alcohol, concentrating and mixing the extraction liquid with surfactant, conducting centrifugation to obtain supernatant, then adding the obtained tobacco tar, conducting stirring so that the mixture can be dissolved sufficiently, then conducting extraction with diethyl ether, concentrating and mixing extraction liquid with surfactant once again, and conducting centrifugal separation to obtain the water-based oil stain cleaning agent. The method has the advantages that the preparation method is simple, and the stain removal rate of an obtained product is 12% and above higher than that of other types of cleaning agents; the using effect is good, and the capability of removing old sticky oil stains is great.

Description

Technical field [0001] The invention relates to a preparation method of a water-based oil stain cleaning agent, and belongs to the field of cleaning agent preparation. Background technique [0002] Water-based cleaning agent is the use of surfactants, emulsifiers, penetrants, etc. to achieve the cleaning of oil, grease and grease by the wetting, emulsifying, permeating, dispersing, and solubilizing effects; the meaning of water-based cleaning agents is also It can be simply said to be a cleaning agent that is compatible with water and can be diluted with water. It is widely used in industrial cleaning of plastics, optical glass lenses, metal products (copper, iron, aluminum, steel, zinc, alloy) and other materials to clean the surface drawing oil, cutting oil, anti-rust oil, lubricating oil, stamping oil Various oil, stains, grease, etc. [0003] At present, the commonly used cleaning agents include solvent-based cleaning agents, strong alkaline cleaning agents and surfactant-bas...
