Abstract

The invention relates to a capsule type oil dispersant and a preparation method thereof, belonging to the technical field of petrochemical environmental protection treatment agents. The invention mainly includes a capsule shell and a degreasing agent capsule core. Firstly, tea saponin, nonionic surfactant, emulsifier, dispersant, etc. are mixed to obtain a degreasing agent capsule core, and then sodium alginate solution and tea extract are extracted. Konjac powder, glycerin, etc. are stirred and mixed to obtain a film-forming solution. The film-forming solution is vacuum degassed, and the defoamed film-forming solution is dipped in glue, calcified and formed, and then dried, demoulded, and cut to obtain capsules. shell, and finally inject the oil dispersant capsule core into the capsule shell and seal it. After the present invention is put into use, the capsule shell will be slowly hydrolyzed, and substances such as glycerin and tea extract can not only weaken the force between oil molecules, but also substances such as sodium alginate can increase the stability of the emulsion during the dispersion process. Thus, the emulsification efficiency is greatly improved, and the natural surfactant is used at the same time, which reduces the pollution to seawater.

Description

technical field [0001] The invention relates to a capsule type oil dispersant and a preparation method thereof, belonging to the technical field of petrochemical environmental protection treatment agents. Background technique [0002] During the exploration and development of offshore oil fields and the marine transportation of oil products, there are often occurrences of crude oil and oil products leakage and oil spill accidents, resulting in oil slick pollution on the sea surface. Oil slick pollution on the sea surface will affect the quality of seawater, affect marine life, and even affect the marine ecological environment in severe cases. Therefore, taking effective measures to control and eliminate oil slick pollution on the sea surface is also a necessary means to protect the marine ecological environment while strictly preventing leakage and oil spill accidents. Oil dispersant, also known as oil spill dispersant, is composed of a variety of surfactants and strong pen...
