Problems solved by technology

On the one hand, if the outer packaging or other anti-counterfeiting parts of the product are used by criminals to repackage inferior oil products, although the external identification is true, the oil products are still counterfeit and inferior products, and the identification of the oil itself cannot be realized And anti-counterfeiting, it cannot completely eliminate the existence of fake and inferior oil products; on the other hand, the use of this anti-counterfeiting technology requires additional design and manufacture of external packaging or anti-counterfeiting components, and the process is often more complicated, which will also lead to an increase in the production cost of the product

Embodiment 1

[0034] A preparation method of anti-counterfeit oil, comprising the following steps:

[0035] (1) In the oleic acid / oleylamine system, add zinc oxide and cadmium oxide as precursor sources, wherein the molar ratio of zinc to cadmium is 20:1; heat to 220°C to react zinc oxide, cadmium oxide and oleic acid complete, to obtain zinc oleate and cadmium oleate; raise the temperature to 280°C, add selenium oleate and sulfur oleate, and react at this temperature for 20 minutes to obtain ZnCdSe / ZnS quantum dot material; add ZnCdSe / ZnS quantum dot material to n-hexane In alkane, disperse by stirring to obtain anti-counterfeiting agent;

[0036] Among them, the ZnCdSe / ZnS quantum dot material is one of the II-VI semiconductor quantum dot materials, the emission wavelength is 620nm, the emission half-maximum width is 30nm, and the particle size is 10nm; the concentration of ZnCdSe / ZnS quantum dot material in the anti-counterfeiting agent 10mg / mL;

[0037] (2) Use a pipette gun to pipett...

Embodiment 2

[0048] The preparation method of the anti-counterfeit oil in Example 2 is basically the same as that in Example 1, the only difference being that in Example 2, after the anti-counterfeit agent is added to the lubricating oil, the method of vacuum pumping is used to remove n-hexane to obtain the anti-counterfeit oil products to reduce the influence of heating temperature on some oil products that are sensitive to heat, and ensure that the quality of oil products will not be affected during the process of adding anti-counterfeiting agents.

[0049] A preparation method of anti-counterfeit oil, comprising the following steps:

[0050] (1) In the oleic acid / oleylamine system, add zinc oxide and cadmium oxide as precursor sources, wherein the molar ratio of zinc to cadmium is 20:1; heat to 220°C to react zinc oxide, cadmium oxide and oleic acid complete, to obtain zinc oleate and cadmium oleate; raise the temperature to 280°C, add selenium oleate and sulfur oleate, and react at thi...

Embodiment 3

[0059] A preparation method of anti-counterfeit oil, comprising the following steps:

[0060] (1) the preparation of the first anti-counterfeiting agent: first prepare organic hybridization methylammonium iodide reagent under dark and room temperature conditions; Prepare the inorganic lead bromide reagent that solvent is toluene again; Finally combine organic hybridization methylammonium iodide reagent and Inorganic lead bromide reagents are mixed according to the molar ratio of 1:1, and stirred to obtain CH 3 NH 3 ikBr 2 quantum dot material; the CH 3 NH 3 ikBr 2 The quantum dot material is added to toluene and dispersed by shaking to obtain the first anti-counterfeiting agent;

[0061] (2) Preparation of the second anti-counterfeiting agent: first in the oleic acid / oleylamine system, add lead oxide precursor source; be heated to 160 ℃ to make lead oxide and oleic acid react completely, obtain lead oleate transparent solution; heat up to 220 ℃ , adding a selenium oleate...

Abstract

The invention belongs to the technical field of fluorescent anti-counterfeiting, and discloses an anti-counterfeiting oil product, which comprises an anti-counterfeiting agent, wherein the anti-counterfeiting agent comprises a quantum dot material and a solvent; the emission wavelength of the quantum dot material is 450-1200 nm, the half-peak width is 10-50 nm, and the particle diameter is 1-100 nm; the concentration of the quantum dot material in the anti-counterfeiting oil product is 0.1-2 mg / L. The anti-counterfeiting oil product can realize identification and anti-counterfeiting of the oilproduct itself, and can greatly improve the anti-counterfeiting capability of the oil product. Under the condition of 100 DEG C or 0 DEG C, the oil product disclosed by the invention is circularly reserved for 2 days and circulated for 5 times, quantum dots in the oil product do not agglomerate or agglomerate, and the anti-counterfeiting oil product is stored for a long time under the condition of room temperature, so that the anti-counterfeiting oil product does not have bottom mudation, delamination and discoloration phenomena, and the viscosity, surface tension and leveling performance ofthe anti-counterfeiting oil product do not change.

Description

technical field [0001] The invention belongs to the technical field of fluorescence anti-counterfeiting, and in particular relates to an anti-counterfeiting oil product and a preparation method thereof. Background technique [0002] In order to identify and fight against counterfeit and shoddy lubricating oil products on the market, it is necessary to adopt some anti-counterfeiting methods for the products. At present, the oil anti-counterfeiting method of lubricating oil mostly adopts the method of indirect anti-counterfeiting, that is, adopts anti-counterfeiting external packaging or anti-counterfeiting components with complex structures, and realizes anti-counterfeiting and identification through identification of external packaging or anti-counterfeiting components. Since this kind of anti-counterfeiting technology does not carry out anti-counterfeiting identification on the content of the target product itself, but on its matching appendages, it can only indirectly conf...
