Embodiment

[0014] A low-temperature type oil spill dispersant, which is composed of the following raw materials by weight (kg): Sorbitan polyoxyethylene ether tetraoleate monolaurate 8, Isostearyl polyoxyethylene ether linoleate 5, Polyoxypropylene Lanolate 4, Coco Rapeseed Oleate 10, Propoxylated Myristyl Propionate 7, Fatty Acid Methyl Ester Ethoxylate Sulfonate 12, Cetearyl Glucoside 6. Glycerin polyoxyethylene ether ethyl hexanoate 4.5.

[0015] A preparation method of a low-temperature type oil spill dispersant, comprising the following steps:

[0016] (1) Mix sorbitol polyoxyethylene ether tetraoleate monolaurate, polyoxypropylene lanolate, cetearyl glucoside, glycerol polyoxyethylene ether ethyl hexanoate, and then Stir magnetically for 6 minutes at a power of 350W and a rotational speed of 1200r / min to obtain Mixture A;

[0017] (2) Mix the rest of the raw materials evenly, then stir in microwave for 4 minutes under the condition of microwave power of 550W and rotating speed of...

Abstract

The invention discloses a low-temperature oil spill dispersant and a preparation method thereof. The low-temperature oil spill dispersant is composed of, by weight, 5-10 parts of sorbitol polyoxyethylene ether tetraoleate monolaurate, 4-7 parts of isostearyl alcohol polyoxyethylene ether linoleate, 3-5 parts of lanolin acid polyoxypropylene ester, 8-12 parts of coconut oil alcohol rapeseed oleate, 6-9 parts of propoxylated tetradecyl propionate, 10-15 parts of fatty acid methyl ester ethoxylate sulfonate, 4-8 parts of cetearyl glucoside and 3-6 parts of glycerin polyoxyethylene ether ethyl caproate. The oil spill dispersant is high in resistance to low temperature, has excellent emulsification and dispersion performance in low-temperature environment (lower than or equal to 5 DEG C), can quickly emulsify and disperse spill oil and is of important significance in improving using effect, expanding medical range and effectively eliminating oil spill pollution.

Description

technical field [0001] The invention relates to a low-temperature type 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. [0003] Oil spill dispersant is commonly known as "oil dispersant". It has the characteristics of reducing the viscosity and surface tension of oil spill, which is conducive to the emulsification and dispersion of oil spill, and the full contact and mixing of oil and water, so that the oil is easy to be biodegraded by water. , purified by the water body. Rational use of oil spill dispersants is...
