Preparation method for natural non-corrosive oil remover

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...

Problems solved by technology

[0003] The technical problem mainly solved by the present invention is: the degreasing effect of the traditional degreasing agent is not ideal, and the existing non-metallic degreasing agent has the technical problem of high corrosiveness, which affects its service life, and provides a natural non-corrosive The preparation method of the degreasing agent, the present invention first adopts anhydrous calcium chloride, absolute ethanol etc. to stir and mix, place in a water bath to heat up and then filter, collect the filter cake and dry at high temperature after washing to obtain a crude extract, and stir Mix and heat to reflux, let stand, cool, suction filter, collect the filter cake, wash with petroleum ether to prepare a complex complex; finally select the leaves of the tung flower tree, wash them, dry them, grind them, and collect the tung flower tree leaf particles. Stir and mix it with petroleum ether, filter and collect the filter cake at high temperature, stir and mix it with absolute ethanol, and obtain an extraction modified liquid after ultrasonic dispersion, and finally stir and mix the extracted modified liquid with deionized water, After ultrasonic dispersion, the modified dispersion is collected, and a portion of polyvinyl alcohol and nano-aluminum hydroxide are added to a beaker, heated and stirred, then cooled to room temperature, and a natural non-corrosive degreasing agent can be prepared. After use, the natural non-corrosive degreasing agent obtained in the present invention can not only remove oil stains, but also has strong dissolving power and no corrosion, so it is easy to use and has a wider application prospect
