preparation example Construction

[0034] The preparation method of the above-mentioned modified light conversion material comprises the following steps:

[0035] (1) Fully mix the photostabilizer and the barrier material in the aqueous solution to form a micellar solution;

[0036] (2) Add light-converting material to the micellar solution, mix well, and cure at 15° C. to 80° C. to obtain light-converting material.

[0037] A third aspect of the present invention provides:

[0038] The application of the above modified light conversion material in a light conversion film, the modified light conversion material is the above modified light conversion material, or is obtained by the above preparation method.

Embodiment 1

[0041] Weigh 1 mass part of phenyl-o-hydroxybenzoate and 95 mass parts of PVDC in the aqueous solution and mix well to form a micellar solution; then add 4 mass parts of light-changing agent CaS:Eu, Mn to the micellar solution, After mixing, solidify at 25°C to obtain a modified light-converting material.

Embodiment 2

[0043] Weigh 10 parts by mass of phenyl-o-hydroxybenzoate and 50 parts by mass of PVDC in an aqueous solution and mix well to form a micellar solution; then add 40 parts by mass of light-changing agent CuInSSe to the micellar solution, and mix them in Curing at 50°C to obtain a modified light conversion material.

Abstract

The invention provides a modified light conversion material, a preparation method and an application thereof. The modified light conversion material includes a light stabilizer and a light conversion agent coated with a barrier material. The light-converting material is coated and modified by micelles containing both barrier materials and light stabilizers. While the light stabilizer absorbs ultraviolet radiation and prolongs the life of the light-converting material, the barrier material is used to reabsorb the remaining ultraviolet rays and prevent water vapor. The contact with oxygen further improves the stability of the light conversion material.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a modified light conversion material and its preparation method and application. Background technique [0002] Rare earth red light materials are added to the light conversion film as a light conversion agent, which can significantly increase the yield of crops. However, this type of material is easily decomposed under the action of water vapor and UV radiation, resulting in a light conversion effect of 0.5 to 3 months. within gradually disappears. The researchers modified the surface of the light conversion agent composed of MS:Eu,Re, such as silicon-coated aluminum. Although the timeliness of light conversion is slightly extended, such modified materials cannot overcome the influence of water vapor. It cannot prevent ultraviolet rays, so far it has not been able to overcome the stability problem of MS:Eu,Re; and the light conversion agent composed of NInS2-xSex is a new ty...
