Application of d-a Type Organic Doped Crystal Afterglow Materials in Oil

Abstract

The invention discloses the application of a D-A type organic doped crystal afterglow material in oil. The D-A type organic doped crystal afterglow material is put into the oil, and the D-A type organic doped crystal afterglow material is The long afterglow luminescence time of afterglow material in oil is 3-6s. The D-A type organic doped crystalline afterglow material of the present invention is a solid powder with small particles and uniform size. When it is put into oil, the oil will not affect the long afterglow luminescence performance of the D-A type organic doped crystalline afterglow material. , D-A type organic doped crystalline afterglow material will not affect the use of oil. Among them, the D-A type organic doped crystalline afterglow material can be used as anti-counterfeiting of oil, the D-A type organic doped crystalline afterglow material is placed in the oil, and the D-A type organic doped crystalline afterglow material is used as the oil burns. The material is biodegradable and does not affect the life of the machine and engine.

Description

technical field [0001] The invention belongs to the technical field of organic long afterglow crystal materials, and specifically relates to the application of a D-A type organic doped crystal afterglow material in oil. Background technique [0002] With the continuous development of the social economy, the anti-counterfeiting industry has gradually developed in order to adapt to the development of the market economy and the needs of commodity anti-counterfeiting. Anti-counterfeiting is an effective means to avoid the behavior of the main body of the market economy. etc. are widely used. For the domestic market where counterfeit goods are rampant, anti-counterfeiting has always been an important basis for consumers to judge the authenticity of merchants' products. Anti-counterfeiting can protect the brand image of products, not only can dispel consumers' hesitation and worries when purchasing, but also effectively protect consumers' legality. The most important thing is to ...

Problems solved by technology

[0003] At present, some scientific research workers consider the method of blending anti-counterfeiting materials and oils to ensure the quality of products, but the current long-lasting anti-counterfeiting materials are mostly inorganic materials. Although inorganic long-lasting anti-counterfeiting materials have certain high stability, 1 ) but its synthesis is difficult, the synthesis conditions are harsh and complicated, and generally require a high temperature of more than 1000 degrees Celsius; 2) it usually needs to be doped with inorganic rare earth materials, which is expensive and toxic; Bottom and large particles

4) The decomposition temperature is high, and it is difficult to degrade after it is used for anti-counterfeiting. This will cause oil products to remain in the engine or other instruments during use. The remaining anti-counterfeiting materials will affect the life of the engine or instrument on the one hand. At the same time, it will affect the purity and quality of the product. More importantly, too much anti-counterfeiting material in the machine will affect the heat dissipation of the machine, which can easily cause serious accidents. Therefore, it is difficult for this kind of inorganic anti-counterfeiting material that is difficult to decompose Large-scale application, so it is urgent to find other anti-counterfeiting functional materials that are easy to decompose

On the other hand, although inorganic long-lasting materials have good long-lasting properties, most inorganic long-lasting materials are very unstable in solvents, such as SrAl 2 o 4 :Eu 2+， Dy 3+ The luminous performance has good initial brightness and afterglow time, but the water resistance and oil resistance are extremely poor. It will be hydrolyzed when it meets water or oil solvents, and it will also interact with these solvents, greatly reducing the luminous brightness and time. The inorganic afterglow materials of other systems are in the There are also many other problems in the solution, which will greatly limit the afterglow performance due to the influence of acidity and alkalinity in the solution, so this also affects the anti-counterfeiting application of this type of material in the liquid to a large extent
