[0002]Street "wild advertising", commonly known as urban "psoriasis", not only pollutes and destroys the city appearance, affects the view, but also misleads and confuses the citizens, which is extremely harmful big
Most of the "wild advertisements" are either sprayed with paint or pasted on conspicuous places such as walls, advertising carriers, and bus stop signs with glue. Detergents, decontamination powders, etc. are powerless
Although organic solvents can soak and dissolve paint in theory, organic solvents are generally more toxic. After volatilization and diffusion, they will seriously pollute the environment and cause great harm to the health of cleaning personnel. Moreover, the price of organic solvents is relatively high. "The cost is too high, and it is actually impossible to implement. At the same time, although organic solvents can dissolve colloids, the dissolved dirt has strong adhesion and is not easy to detach from the substrate, and it is still difficult to completely remove it.
The active substance type scavenger cannot dissolve the colloid and cannot be used alone as a scavenger for the colloid
In addition, at the beginning of this century, the simple surfactant sodium petroleum sulfonate was used as the oil displacement agent for poor residual oil recovery in the field of oil exploitation. Therefore, the oil layer at this stage is basically high in glue and asphalt content, and the molecular weight is too large to be viscous and difficult. Poor extraction effect

preparation example Construction

[0045] A kind of preparation method of the degumming oil-displacing agent that active matter is combined with solvent, comprises the following steps:

[0046] (i) Configure surfactant

[0047] Slowly add 1 / 2 of the amount of oleic acid to the alkanolamine under stirring at 60 rpm. After the dropwise addition, test the pH value of the solution. When the pH value is greater than 9, continue to add 1 / 4 of the amount used. A certain amount of oleic acid, test the pH value of the solution again, then continue to drip oleic acid, repeat the operation until the detection pH value is between 8.4-9, stop adding oleic acid; or directly add the oleic acid ethanolamine series products required by the formula Such as triethanolamine oleate;

[0048] (ii) Configuration of the product

[0049] Add fatty alcohol, dichloromethane, benzyl alcohol, ethylene glycol and ethers thereof or polyethylene glycol and ethers thereof to the solution obtained in step (i), and stir evenly;

[0050] (iii)...

Embodiment 1

[0054] A kind of preparation method of the degumming oil-displacing agent that active matter is combined with solvent, comprises the following steps:

[0055] (i) Configure surfactant

[0056] The oleic acid with a proportion of 1 is slowly added to the alkanolamine with a proportion of 1 (its total amount is 5-20Kg) under stirring at 60 rpm. After the slow addition, test the pH value of the solution. When the pH value is greater than 9, continue to add oleic acid with a ratio of 1, test the pH value of the solution again, then continue to add oleic acid slowly, and repeat the operation until the pH value is detected to be between 8.4-9 to stop adding oleic acid; or directly Add oleic ethanolamine oleic acid triethanolamine.

[0057] (ii) Configuration of the product

[0058] Add 8kg of diacetone alcohol, 1kg of dichloromethane, and 0.3kg of diglyme to the solution obtained in step (i), and stir evenly;

Abstract

The invention discloses an active matter and solvent bonded degumming oil displacement agent, a method for preparing the same and application of the active matter and solvent bonded degumming oil displacement agent to chemical-process oil production. The active matter and solvent bonded degumming oil displacement agent comprises surfactants, fatty alcohol, dichloromethane, benzyl alcohol, ethyleneglycol, ether of the ethylene glycol or poly-glycol and ether of the poly-glycol, water and the like. The method includes steps of (i), preparing the surfactants; (ii), preparing products; (iii), diluting the products. The active matter and solvent bonded degumming oil displacement agent, the method and the application have the advantages that the active matter and solvent bonded degumming oil displacement agent is applicable to scrubbing or is applicable to being sprayed on paint and printing ink by the aid of mist spray appliances or can be used for 'illegal advertisements' adhered by adhesive, is high in soaking and melting speed, large in applicable area, low in cost and free of environmental pollution, is harmless on the health of staffs and is an affordable 'illegal advertisement' cleaning agent, and thorough scrubbing effects can be realized by the active matter and solvent bonded degumming oil displacement agent; the active matter and solvent bonded degumming oil displacementagent further can be used for removing heavy grease stain of range hoods and is applicable to exploiting thick petroleum ore deposits with high gum contents.
