preparation example Construction

[0036] The preparation method comprises the following steps:

[0037] Step S101, concentration is 0.1mol / L europium chloride (EuCl 3 ·6H 2 O) The aqueous solution reacts with the first ligand α-thienoyltrifluoroacetone (TTA), and triphenylphosphine oxide (TPPO) is used as the second ligand to synthesize the ternary complex Eu(TTA) of europium 3 TPPO (ETT);

[0038] Step S102, the synthetic ternary complex Eu(TTA) of europium 3 TPPO (ETT) was dissolved in an organic solvent with a proportion of 0.3wt% by weight and low-density polyethylene to prepare a nanometer rare earth complex light conversion film.

[0039] In the embodiment of the present invention, the preparation method further includes the following steps: using the high polymer extrusion molding process, adding the nano-europium rare earth complex to the low-density polyethylene masterbatch to obtain a uniform and transparent polymer film, Its red fluorescence can be clearly seen at ultraviolet light (365nm).

Abstract

The invention discloses a preparation method of a rare earth complex / polymer naocomposite plastic film. The method comprises the following steps: reacting an aqueous europium chloride solution having a concentration of 0.1mol / L with a first ligand TTA, and using TPPO as a second ligand to synthesize Eu(TTA)3TPPO(ETT); and respectively dissolving Eu(TTA)3TPPO(ETT) having a weight percentage of 0.3wt% and low-density polyethylene in an organic solvent to prepare a nanometer rare earth complex light conversion film, and utilizing the small size effect of Eu(TTA)3TPPO(ETT) to make Eu(TTA)3TPPO(ETT) have a good compatibility in the low density polyethylene in order to obtain a uniform and transparent composite film. The film absorbs ultraviolet light in daylight and converts the ultraviolet light into red light helpful for the growth of plants, so the light conversion effect is performed. A polymer extrusion molding technology can also be utilized in the invention to add 0.3wt% of the nano-europium rare earth complex to a low density polyethylene master batch in order to obtain a uniform and transparent polymer film, and red fluorescence of the polymer can be obviously seen at ultraviolet light (365nm).

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a preparation method of a rare earth complex / polymer nanocomposite plastic film. Background technique [0002] There have been research reports on rare earth complex light converting agents and light converting agricultural films in my country. However, the size of the light-changing agent is mostly micron-scale materials. Only the light-converting agricultural film obtained by modifying polyethylene resin with montmorillonite to make the matrix material a nano-intercalation structure, and then compounding with micron-scale rare earth complexes has not been seen in this paper. Invention of the same report. Contents of the invention [0003] The present invention provides a preparation method of rare earth complex / polymer nanocomposite plastic film, aiming to solve the problem of existing research reports on rare earth complex light converting agents and ...
