Problems solved by technology

Most of the existing oil dispersants use chemically synthesized surfactants as emulsifiers and liquid paraffin or aviation kerosene as solvents. Not only the dispersion speed is slow and the degradation rate is low, but the more important thing is that they are more toxic. At the same time, it will cause secondary pollution to the environment. Once aquatic poisoning occurs, it will eventually threaten the health of other organisms and human beings along with the food chain.

Embodiment 1

[0014] Get the rhamnose ester (Daqing Wotaisi Chemical Co., Ltd. production) that mass percent is 25%, the mixture (polysorbate and sorbitan fatty acid ester) that mass percent is 25% The mass ratio of fatty acid ester is 2:3), the mass percentage is 25% ethylene glycol butyl ether, and the balance is water.

[0015] The preparation method proceeds as follows:

[0016] a. first add the metered rhamnosyl ester to the mixture of the metered polysorbate and sorbitan fatty acid ester and stir;

[0017] b. Add the measured ethylene glycol butyl ether into the mixture obtained in step a and stir evenly;

[0018] c. Add measured amount of water to the mixture obtained in step b and stir well.

Embodiment 2

[0020] Get the rhamnose ester (Daqing Wotaisi Chemical Co., Ltd. production) that is 50% by mass percentage, the mixture of polysorbate and sorbitan fatty acid ester (polysorbate and sorbitan) that mass percentage is 1.5% The mass ratio of fatty acid ester is 1:2), the mass percentage is 20% ethylene glycol butyl ether, and the balance is water.

[0021] The preparation method is the same as in Example 1.

Embodiment 3

[0023] Get the rhamnosyl ester that mass percent is 1.5% (select the rhamnosyl ester fermented liquid that Daqing Wotaisi Chemical Co., Ltd. produces, and its rhamnosyl mass percent is 1.5% of embodiment 3), mass percent is 50% A mixture of polysorbate and sorbitan fatty acid ester (the mass ratio of polysorbate to sorbitan fatty acid ester is 1:3), the mass percentage is 10% ethylene glycol butyl ether, and the balance is water.

[0024] The preparation method is the same as in Example 1.

Abstract

The invention discloses a biological environmental-protection detergent, which comprises the following raw materials in weight percentage: 1.5-0 percent of a biological surface active agent, 1.5-50 percent of a non-ionic surface active agent which comes from agricultural and sideline products and can be used as a food emulsifying agent, 10-80 percent of awater-soluble oxygen-contained solvent and the balance of water. All the components interact, thereby, overflowing oil can be rapidly emulsified; the biological degradation rate is high; secondary pollution cannot be caused to water areas; and the phenomenon that the health of other organisms and human is influenced because aquatic organisms are poisoned by the detergent is avoided.

Description

technical field [0001] The invention relates to an oil dispersant, especially a bio-environmental environment-friendly oil dispersant that can quickly emulsify and disperse oil spilled on the water surface, has a high biodegradation rate, does not cause secondary pollution to water areas, and is non-toxic and harmless to organisms and its preparation method. Background technique [0002] At present, in order to reduce the pollution of the water environment caused by oil spills on water surfaces (sea, river, lake, etc.), degreasing with oil dispersants is one of the treatment methods. Therefore, the emulsification and dispersion speed of oil spills, the biodegradation rate of the dispersant itself and the acute toxicity of fish are important indicators to measure the quality of the dispersant. Most of the existing oil dispersants use chemically synthesized surfactants as emulsifiers and liquid paraffin or aviation kerosene as solvents. Not only the dispersion speed is slow a...
