Abstract

The invention discloses a low-toxicity oil spill dispersant and a preparation method thereof. The low-toxicity oil spill dispersant is composed of, by weight, 5-10 parts of ethoxylated methyl glucose sesquioctanoate, 8-12 parts of propoxylated stearyl benzoate, 5-10 parts of octyl dodecyl glucoside, 10-15 parts of propoxy ethoxylated palm oil alcohol hexyl diamino diformiate, 10 parts of polyglycerin, 4-9 parts of polyricinoleate, 7-12 parts of C12-15 alcohol benzoate and 5-10 parts of dodecyl hydroxypropyl sulfobetaine. Low-toxicity surfactants like are adopted to prepare the oil spill dispersant, so that the oil spill dispersant has excellent emulsification and dispersion performance, has the advantage of low toxicity and is nontoxic to marine organisms, free of secondary environment pollution, safe and environment-friendly.

Description

technical field [0001] The invention relates to a low-toxic oil spill dispersant and a preparation method thereof, belonging to the field of water body pollution prevention and control. Background technique [0002] With the increasing demand for oil and its products worldwide, the amount of offshore oil extraction and transportation has increased significantly, and oil spill accidents have occurred from time to time. Oil spill pollution has become the most frequent occurrence and widest distribution of various marine pollution types. The broadest and most dangerous one. A variety of emergency measures can be taken after the oil spill occurs, such as the use of oil boom containment, mechanical recovery, on-site burning or spraying of chemical agents, etc. Among them, spraying oil spill dispersant on the oil spill sea surface is an earlier method. , especially in the case of strong winds and waves or a large amount of oil entering the sea and a low recovery rate, the use of ...
