Problems solved by technology

[0004] In the existing industry, there is a lack of cleaning agent standards for oil stains on automotive equipment parts. An important reason for the lack of standards is the lack of standard and reliable artificial oil stains
The cleaning rate test methods described in various enterprise standard documents are different, and the synthesis methods of artificial oil stains are also different, which cannot be generally applied to the cleaning agent test of oil stains on automotive equipment parts
Due to the lack of standard oil stains, the result is that the general cleaning rate of the cleaning agent is generally high, but the actual application is very different from the test results
At the same time, the problem of the existing artificial oil stain preparation is that the repeatability is poor. The oil stains prepared by repeated tests have different viscosities and adhesions. During the test, the cleaning rates are all lower than 50%, or all are greater than 95%, or No distinguishable cleaning rate gradients, resulting in large fluctuations in repeated experimental data for cleaning power when used for testing

preparation example Construction

[0063] According to one aspect of the present invention, a preparation method of the above-mentioned artificial oil pollution, the preparation method comprises the following steps:

[0064] Provide the mixed oil stain containing mechanical oil, lubricating grease and thickener after heating and dissolving, and then subject the mixed oil stain to oxidation treatment to obtain artificial oil stain.

[0065] The preparation method of the artificial oil stain provided by the present application includes the following steps: providing a mixed oil stain comprising mechanical oil, lubricating grease and a thickener, and then performing oxidation treatment on the mixed oil stain to obtain the artificial oil stain. The above preparation method has the advantage of simple technological process.

[0066] In a preferred embodiment of the present invention, the heating and dissolving temperature is 120°C, and the temperature of the oxidation treatment is 180-260°C;

[0067] As a preferred...

Embodiment 1

[0092]An artificial oil stain, in parts by mass, the artificial oil stain comprises the following components: 10 parts of liquid paraffin, 10 parts of barium petroleum sulfonate, 5 parts of stearic acid, 8 parts of industrial vaseline, 25 parts of 46# machine oil, 30 parts of 68# base oil, 2 parts of calcium-based grease and 10 parts of A100 carbon black;

[0093] The preparation method comprises the following steps:

[0094] (a), provide mixed oil pollution: the raw material of the above formula amount is heated and mixed at 120 ℃ to obtain the mixed oil pollution A;

[0095] (b), oxidation treatment: transfer 200g of mixed oil stain A into a 500ml three-necked flask, then fix the three-necked flask in a 500ml temperature-controlled electric heating mantle, one side nozzle is inserted into a thermometer, and the other side nozzle is passed through a glass tube, A small air pump, an air flow meter and an air guide pipe introduce an air flow of 0.51L / min. A 90° angle glass tub...

Embodiment 2

[0098] In this example, the rest is the same as Example 1, except that both 46# mechanical oil and 68# base oil are replaced with SF15W / 40 engine oil.

Abstract

The invention provides an artificial oil stain, a preparation method and application thereof, and relates to the field of industrial cleaning. The artificial oil stain is mainly prepared by mixing mechanical oil, lubricating grease and a thickener and then undergoing oxidation treatment; wherein, the lubricating grease includes liquid Paraffin, barium petroleum sulfonate, stearic acid and industrial petrolatum. The artificial oil stains prepared by mixing the above-mentioned raw materials through oxidation treatment have achieved a synergistic effect. The prepared artificial oil stains have the characteristics of moderate viscosity and good adhesion, which can well simulate the operation of automobile machinery and equipment for a period of time. Oil pollution produced later.

Description

technical field [0001] The invention relates to the field of industrial cleaning, in particular to an artificial oil stain and a preparation method and application thereof. Background technique [0002] With the increasing number of cars, the daily cleaning and maintenance of cars have become an important part of car beauty, and various cleaning products have emerged one after another. An important indicator for judging the performance of cleaning agents is the cleaning rate. The test of the rate refers to the size of the cleaning agent's ability to clean the dirt under certain conditions, usually expressed as a percentage. Now, organic solvent-based cleaning agents have basically completed the replacement link from non-environmental-friendly components to environmental-friendly components. Under the premise of environmental protection effects and the prohibition of the use of toxic and harmful substances, how to achieve a cleaning rate of more than 80% has become the prepar...
