preparation example Construction

[0029] A kind of preparation method of heavy oil dirt cleaning agent of the present invention, concrete operation steps are as follows:

[0030] Step 1: Prepare Robinia pseudoacacia flower extract

[0031] Step 1.1: crush the fresh locust flower with a crusher, then filter the crushed fresh locust flower to remove the residue to obtain the crude filtrate;

[0032] Step 1.2: Add the crude filtrate into the reaction kettle, then add deionized water into the reaction kettle, raise the temperature to 95°C, boil for 2 hours, then let it cool down naturally, and obtain a clear and transparent liquid A after fine filtration. Add isothiazolinone into A, and the mass ratio of isothiazolinone to liquid A is 1:1000; Stir evenly to obtain Robinia pseudoacacia flower extract;

[0033] Step 1.2 The mass ratio of deionized water to crude filtrate is 1:2.5-3; the fine filter adopts a bag filter of 1250 mesh.

[0034] Step 2: Weigh the following raw materials according to mass percentage: 15...

Embodiment 1

[0041] Step 1: Weigh the following raw materials: 300 kg of Robinia pseudoacacia flower extract prepared above, 150 kg of C9-11 fatty alcohol ethoxylate BEROL266, 120 kg of gemini propyl ethoxy alcohol ether, 30 kg of triethanolamine, 20 kg of butanediol, and isothiazole linone 6kg, deionized water 374kg;

[0042] Step 2: Add the deionized water weighed in step 1 into the reaction kettle, stir and heat up to 40°C, then add the extract of Robinia pseudoacacia flower, stir for 0.8h, then add C9-11 fatty alcohol ethoxylate BEROL266 and Gemini propyl Ethoxy alcohol ether, then add triethanolamine and butanediol, and finally add the isothiazolinone, and continue to stir for 1.5h; when the solution drops to room temperature, a heavy oil stain cleaning agent is obtained.

[0043]The heavy oil stain cleaning agent prepared by the inventive method is applied in the machining workshop of Yanchang Oilfield Equipment Manufacturing Co., Ltd., the cleaning of lathes and milling machine surf...

Embodiment 2

[0045] Step 1: Weigh the following raw materials: 150 kg of Robinia pseudoacacia flower extract prepared above, 70 kg of C9-11 fatty alcohol ethoxylate BEROL266, 50 kg of gemini alkyl glycosides, 50 kg of gemini propyl ethoxy alcohol ethers, 10 kg of triethanolamine, butyl Diol 5kg, isothiazolinone 2kg, deionized water 663kg;

[0046] Step 2: Add the deionized water weighed in step 1 into the reaction kettle, stir to raise the temperature to 40°C, add the extract of Robinia pseudoacacia flower, stir for 1 hour, then add C9-11 fatty alcohol ethoxylate BEROL266, gemini alkyl glycoside And gemini propyl ethoxy alcohol ether, then add triethanolamine and butanediol, finally add the isothiazolinone, and continue to stir for 2 hours; when the solution drops to room temperature, a heavy oil stain cleaning agent is obtained.

Abstract

The invention discloses a heavy oil stain cleaning agent. The heavy oil stain cleaning agent is prepared from the following components in percentage by mass: 15 to 30 percent of robinia pseudacacia flower extracting solution, 5 to 15 percent of high-efficiency emulsifier, 5 to 12 percent of oil stain cleaning agent, 0.6 to 3 percent of triethanolamine, 0.5 to 2 percent of butanediol, 0.2 to 0.6 percent of isothiazolone, 0 to 2 percent of pH modifier and 37.4 to 71.8 percent of deionized water, wherein the sum of the mass percentages of all the components is 100 percent. The invention further discloses a preparation method of the heavy oil stain cleaning agent. The preparation method comprises the following steps: preparing the robinia pseudacacia flower extracting solution; adding the robinia pseudacacia flower extracting solution, the high efficiency emulsifier, the oil stain cleaning agent, the triethanolamine, the butanediol and the isothiazolone into the deionized water for uniformmixing and adjusting the pH to 6 to 8, thus obtaining the heavy oil stain cleaning agent. A surfactant used in the heavy oil stain cleaning agent disclosed by the invention is an environment-friendlyproduct with low toxicity and high activity and does no harm to the skin and the environment.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a cleaning agent for heavy oil pollution, and also relates to a preparation method of the cleaning agent for heavy oil pollution. Background technique [0002] During the maintenance and use of industrial equipment, some oil stains will be produced on the surface of the equipment, which will affect the appearance and performance of the equipment after a long time; in the workover operation of oil and gas wells, there will always be some heavy oil stains sprayed on the equipment and staff's clothes and Hands; cooking in the kitchen in life will also cause heavy oil pollution to kitchen equipment and walls. If it is not cleaned for a long time, it will shorten the service life of the equipment and affect the appearance of the kitchen. Generally, the cleaning agents on the market are difficult to clean these heavy oily dirt. Even if they can be cleaned, the amount...
