Abstract

The invention discloses a rare earth complex agricultural light conversion film which is composed of at least one layer of co-extrusion blown film, naphthyridine light conversion agents are added into one or more layers of the co-extrusion blown film, the co-extrusion blown film layer containing the naphthyridine light conversion agents is a light conversion layer, and the addition mass percentage of the naphthyridine light conversion agents in the light conversion layer is 0.2-2%; an alkaline additive is also added into the light conversion layer containing the naphthyridine light conversion agent, and the adding mass percent of the alkaline additive is 0.2-5%. The naphthyridine rare earth complex light conversion film prepared by the invention can obtain high photoluminescence quantum yield and excellent light stability, and solves the technical problems of low luminous efficiency and unstable quality of the existing light conversion film prepared based on naphthyridine rare earth complexes.

Description

technical field [0001] The invention belongs to the field of agricultural film materials, and relates to a rare earth complex agricultural light conversion film with high luminous efficiency and long service life and a preparation method thereof. Background technique [0002] Agricultural plastic film (abbreviated as agricultural film) is one of the three major agricultural production materials in my country. The area of ​​greenhouse film in China accounts for more than 85% of the world's total area. It is widely used and has a very broad market prospect. Agricultural plastic film is mainly composed of additives such as resin, heat stabilizer, light stabilizer, heat preservation agent, and dripping agent. Among them, heat stabilizer and light stabilizer are mainly used to improve the processability, mechanical strength and anti-aging properties of plastics. The thermal insulation agent and dripping agent are functional additives, which can improve the thermal insulation perf...
