Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning agent preparation, and more specifically, relates to a cleaning agent for seawater surface floating components, a preparation method thereof, and an application thereof. Background Art

[0002] When equipment components are in long-term contact with seawater, various pollutants such as oil stains and marine biological impurities will adhere to their outer surfaces. Moreover, with the long-term immersion of seawater, a lot of salt stains will also be generated on their outer surfaces. The long-term attachment of these stains to the equipment surface will affect its use. Therefore, regular cleaning is required. The common cleaning methods are direct water flushing and scrubbing. However, many stains are not easily washed off directly, and the cleaning efficiency is average. For this reason, various cleaning agents suitable for cleaning marine ships or offshore equipment have emerged on the market. However, either the cleaning effect of these cleaners is relatively single, for example, they can only clean oil stains and cannot clean biological attachments, salt stains, etc., or their compositions contain too many chemical raw materials, which will damage the marine environment and marine organisms, resulting in poor use effects. Therefore, the present application proposes a cleaning agent for seawater surface floating components, a preparation method thereof, and an application thereof. Summary of the Invention

[0010] According to the present invention, preferably, the preparation method of the ginger extract comprises: successively crushing ginger, soaking it in water, subjecting it to ultrasonic extraction, filtering, centrifuging, and taking the supernatant to obtain the ginger extract.

[0011] According to the present invention, preferably, the soaking time in water is 1-3 h, and the amount of water used for soaking is 6-10 times the amount of the ginger.

[0012] According to the present invention, preferably, the ultrasonic extraction time is 10-15 min.

[0013] According to the present invention, preferably, the density of the ginger extract is 1.02-1.08 g / cm 3 。

[0014] In the second aspect of the present invention, there is provided a preparation method of the cleaning agent for the seawater surface floating assembly as described above. The preparation method comprises the following steps:

[0015] S1: Mix and stir the castor oil, citric acid, emulsifier and solvent evenly to obtain mixture A;

[0016] S2: Mix and stir the lubricant, foaming agent and sodium alginate evenly to obtain mixture B;

[0017] S3: Heat and mix and stir the ginger extract and water evenly, and then cool to obtain mixture C;

[0019] According to the present invention, preferably, in step S2, the mixing and stirring temperature is 30-40 °C and the time is 30-45 min.

[0020] According to the present invention, preferably, in step S3, the heating and mixing and stirring temperature is 40-60 °C.

[0021] According to the present invention, preferably, in step S4, the mixing and stirring time of mixture A and mixture B is 10-20 min; the standing time is 10-20 min.

[0022] The third aspect of the present invention provides the application of the cleaning agent for the floating component on the sea water surface in cleaning the stains on the floating component on the sea water surface, and the stains on the floating component on the sea water surface are at least one of oil stains, marine organisms and salt stains.

[0023] According to the present invention, preferably, the addition amount of the cleaning agent for the floating component on the sea water surface does not exceed 2% of the total cleaning water.

[0024] According to the present invention, preferably, the oil stain is petroleum oil stain (leaked by ships on the sea surface) and / or domestic oil stain.

[0025] According to the present invention, preferably, the marine organism is seagrass and / or small marine organisms.

[0026] According to the present invention, preferably, the salt stain is calcium carbonate precipitate and / or magnesium carbonate precipitate.

[0027] In the present invention, the principle of the cleaning agent of the present invention for cleaning stains is as follows:

[0028] For the removal of oil stains: It is mainly achieved through the composition of "castor oil, citric acid, emulsifier (glycerol monostearate), solvent (ethanol)" in the cleaning agent. Among them, the hydrolysis reaction of castor oil and citric acid with grease is mainly relied on to remove the oil stains.

[0029] For the removal of marine organisms: It is mainly achieved through "lubricants (glycerol, turpentine), sodium alginate, foaming agent (potassium bitartrate)". Among them, glycerol and turpentine have excellent lubrication effects, which can reduce the viscosity between marine organisms and components and facilitate removal. Sodium alginate can exhibit polyanion behavior in aqueous solution and has a certain adhesiveness, which is convenient for sticking and removing marine organisms during the brushing process.

[0030] For the removal of salt stains: It is mainly achieved through citric acid and ginger extract. The solubility of calcium and magnesium ion carbonates (calcium carbonate or magnesium carbonate) in water will be greatly reduced. Most of the insoluble (calcium carbonate or magnesium carbonate) will precipitate out of the water to form salt stains. Citric acid and ginger extract are acidic substances that can react with them and dissolve them, thus achieving the effect of removing salt stains.

[0031] The beneficial effects of the technical solution of the present invention are as follows:

[0032] The cleaning agent of the present invention solves the problems that the existing cleaning agents cannot effectively remove oil stains, marine organisms and salt stains on the floating component on the sea water surface and are not environmentally friendly.

[0033] The cleaning agent provided by the present invention uses plant extracts to clean the adhesives on the seawater floating components. The cleaning agent mainly prepared from plant extracts can clean more than 98% of the stains on the component surface, and there are no components harmful to the human body and the environment in this cleaning agent. It is non-toxic to aquatic organisms, the VOC release amount is less than 0.5%, and it has no irritation to the skin, respiratory tract, and digestive system. The addition amount of the cleaning agent provided by the present invention is extremely low, and the cleaning cost is low.
