Example Embodiment

[0014] Example 1

[0015] First, according to the mass ratio of 1:3:10, stir and mix anhydrous calcium chloride, anhydrous ethanol and lanolin alcohol and place them in a water bath at 55°C for 2 hours. After the water bath is heated, filter and collect the filter cake. After washing the filter cake 3 times with ionized water, it was dried at 65°C for 6 hours to prepare a crude extract; in parts by weight, 15 parts of absolute ethanol, 35 parts of petroleum ether and 10 parts of the crude extract prepared above were weighed out. After stirring, mixing and heating to reflux for 45 minutes, then standing and cooling to room temperature, suction filtration and collecting the filter cake, washing 3 times with petroleum ether, and drying at 55°C for 6 hours to prepare a composite complex for use; The tree leaves are washed and dried at 65°C for 6 hours, then milled and collected the Tung Blossom tree leaf particles, according to the mass ratio of 1:10, stir and mix the Tung Blossom tr...

[0016] Example 2

[0017] First, according to the mass ratio of 1:3:10, stir and mix anhydrous calcium chloride, anhydrous ethanol and lanolin alcohol and place them in a water bath at 60°C for 3 hours. After the water bath is heated, filter and collect the filter cake. After washing the filter cake with ionized water for 5 times, it was dried at 70°C for 8 hours to prepare a crude extract; in parts by weight, weigh 20 parts of absolute ethanol, 40 parts of petroleum ether and 15 parts of the crude extract prepared above. After stirring, mixing and heating to reflux for 60 minutes, then standing and cooling to room temperature, suction filtration and collecting the filter cake, washing with petroleum ether for 5 times, drying at 60°C for 8 hours, to prepare a composite complex for use; The tree leaves were washed and dried at 70℃ for 8 hours, then milled and collected Tung Blossom tree leaf particles, according to the mass ratio of 1:10, stir and mix the Tung Blossom tree leaf pa...

[0018] Example 3

[0019] First, according to the mass ratio of 1:3:10, stir and mix anhydrous calcium chloride, anhydrous ethanol and lanolin alcohol and place them in a water bath at 58°C for 3 hours. After the water bath is heated, filter and collect the filter cake. After washing the filter cake 4 times with ionized water, it was dried at 68°C for 7 hours to prepare a crude extract; in parts by weight, 18 parts of absolute ethanol, 37 parts of petroleum ether and 12 parts of the above-prepared crude extract were respectively weighed After stirring, mixing and heating to reflux for 52 min, then standing and cooling to room temperature, suction filtration and collecting the filter cake, washing 4 times with petroleum ether, and drying at 58°C for 7 hours to prepare a composite complex for use; The tree leaves were washed and dried at 68℃ for 7 hours, then milled and collected Tung tree leaf particles, according to the mass ratio of 1:10, the Tung tree leaf particles and petrole...

Abstract

The invention discloses a preparation method for a natural non-corrosive oil remover, and belongs to the technical field of preparation of oil removers. The preparation method comprises the following steps of: firstly, stirring and mixing anhydrous calcium chloride, absolute ethyl alcohol and the like to obtain a mixture I, putting the mixture I into a water bath to heat, filtering the heated mixture I, collecting a filter cake I, washing the filter cake I, and drying the filter cake I at a high temperature to obtain crude extract, stirring, mixing and heating the crude extract, collecting the filter cake I, and washing the filter cake I with petroleum ether to prepare composite complex; then, selecting leaves of aegiceras corniculatum, washing and drying the leaves of aegiceras corniculatum, grinding and collecting leave particles of aegiceras corniculatum, mixing the leave particles of aegiceras corniculatum with petroleum ether by stirring to obtain a mixture II, filtering the mixture II to collect the filter cake II, mixing the leave particles of aegiceras corniculatum with absolute ethyl alcohol by stirring to prepare extracted modified liquor; and finally, mixing the extracted modified liquor with deionized water by stirring, collecting a modified dispersion liquid, heating the modified dispersion liquid with polyvinyl alcohol and nano aluminum hydroxide, and mixing by stirring, thereby preparing the natural non-corrosive oil remover. After being used, the natural non-corrosive oil remover can remove oil, is strong in dissolving capacity, is incorrosive, is convenient to use, and has a relatively wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of a natural non-corrosive degreasing agent, belonging to the technical field of degreasing agent preparation. Background technique [0002] Degreasing agent is a complex mixture of organic and inorganic chemicals in water base, and is a new type of industrial degreasing agent developed by using the principle of "emulsification" and "saponification". It is widely used in metal processing, food, textile, transportation, shipbuilding, construction, electrical appliances, medicine, chemical industry and other industrial fields. Although the surface substrates to be cleaned are different, the purpose of cleaning is the same, which is to restore the surface of the substrate. cleanliness and maintain the integrity of the substrate surface. The degreasing agent is mainly formulated from various surfactants and builders, and is a liquid cleaning agent, so it is easy to use. In modern industrial cleaning, ultrasoni...
