Embodiment 1

[0025] An emulsified oil produced from high-concentration wastewater, including 64g of base oil, 6g of T301, 14g of T702, 1g of T80, 6g of S80, 1.5g of K12, and 8g of triethanolamine.

[0026] Among them, the base oil is obtained by evaporating and concentrating 100kg of high-concentration wastewater to obtain 2kg of wastewater residue. After the residue is filtered to remove solid impurities, 1mol / L sodium hydroxide solution is added to adjust the pH to 7. After liquid separation, 1kg of viscous is obtained. Petroleum ether is added to the viscous matter to extract and then detected to obtain a base oil with polyalcohols such as C4 alcohols (butanol, isobutanol) as the main component.

[0027] A preparation method of emulsified oil produced from high-concentration wastewater is as follows: add 64g of base oil into a container, heat and stir, and when the temperature rises to 70°C, add T80 1g, S80 6g, K12 1.5g, T702 14g After 30 minutes, add T301 6g and triethanolamine 8g, and...

Embodiment 2

[0030] An emulsified oil produced from high-concentration wastewater, including 63g of base oil, 5g of T301, 0.5g of T406, 14g of T702, 0.5g of T706, 1.5g of T746, 3g of T80, 6g of S80, 1g of K12, and 6g of triethanolamine.

[0031] Wherein, the preparation of base oil is identical with embodiment 1.

[0032] A preparation method of emulsified oil produced from high-concentration wastewater is as follows: add 63g of base oil into a container, heat and stir, and when the temperature rises to 70°C, add 3g of T80, 6g of S80, 1g of K12, and 14g of T702, After 30 minutes, add T301 5g, T406 0.5g, T706 0.5g, T746 1.5g, triethanolamine 6g, and react at 70°C for 2 hours to obtain the desired emulsified oil.

[0033] The prepared emulsified oil can be used as cutting fluid, and the performance data obtained are shown in Table 1.

Embodiment 3

[0035] An emulsified oil produced from high-concentration wastewater, including base oil 63g, T301 4g, T702 12g, T706 0.5g, T746 1g, T80 1.5g, S80 6g, K12 1.5g, triethanolamine 5g, ricinoleic acid methanol Potassium soap 6g.

[0036] Wherein, the preparation of base oil is identical with embodiment 1.

[0037] The preparation process of potassium ricinoleic acid methylate soap is:

[0038] Dissolve 25g of ricinoleic acid in 70g of methanol, raise the temperature to 60°C, add 5g of potassium hydroxide, and react for 60min to obtain potassium ricinoleic acid methylate soap.

[0039] A preparation method of emulsified oil produced from high-concentration wastewater is as follows: add 63g of base oil into a container, heat and stir, and when the temperature rises to 70°C, add T80 1.5g, S80 6g, K12 1.5g, T702 After 30 minutes, add T301 4g, T706 0.5g, T746 1g, triethanolamine 5g, ricinoleic acid methyl potassium soap 6g, and react at 70°C for 2h to obtain the desired emulsified oi...

Abstract

The invention discloses emulsified oil produced by taking high-concentration wastewater as a raw material and a preparation method and application thereof. The emulsified oil is prepared from 50-65 parts of base oil, 6-12 parts of an emulsifier, 13-20 parts of an antirust slow-release agent, 4-8 parts of an extreme pressure agent and 4-8 parts of triethanolamine, the preparation method comprises the following steps: adding the base oil into a container, heating and stirring, adding the emulsifier and part of the antirust agent when the temperature rises to 70 DEG C, adding the extreme pressureagent, the oiliness agent, the residual antirust agent, triethanolamine and the solubilizer after 30 minutes, and reacting to obtain the required emulsified oil. The obtained emulsified oil is used as a cutting fluid, a grinding fluid and a drilling cooling fluid, and the emulsified oil which is widely applied is obtained by blending the contents of different components so that the pollution problem of high-concentration wastewater is solved, the high-concentration wastewater is effectively utilized, and wastes are changed into valuable things.

Description

technical field [0001] The invention relates to the technical field of emulsified oil, in particular to an emulsified oil produced from high-concentration wastewater as a raw material, a preparation method and application thereof. Background technique [0002] Emulsified oil is an indispensable auxiliary material in the metal processing industry, and it is used in various machine tools. The conventional preparation method is to use mechanical oil or synthetic oil as the base oil, supplemented by various additives through deployment and processing. [0003] We often see in our daily work that in the centralized treatment of process wastewater in some enterprises, there is a layer of oily substances floating on the liquid surface of those storage tanks and pools. These oily substances must be sent to waste treatment after passing through the centralized treatment point The central processing method is nothing more than incineration. What these simple treatment methods bring ...
