Anti-aging blue light conversion agent s-triazine derivative and preparation method thereof and prepared agricultural film

Abstract

The invention relates to an anti-aging blue light conversion agent s-triazine derivative and a preparation method thereof and a prepared agricultural film. The preparation method comprises the following steps: dissolving the s-triazine derivative 2, 4- bis(1-naphthylethyl)-6-(3,5-di-tert-butyl-4-hydroxyphenethyl)-s-triazine adopting a three-branch structure, 1-naphthaldehyde and potassium hydroxide by using methanol; dropwise adding a 1,3,5-trimethyl-s-triazine solution into a container to obtain an intermediate product, and then performing a reaction on the intermediate product, 3, 5-di-tert-butyl-4-hydroxybenzaldehyde and potassium hydroxide to obtain a product. The s-triazine derivative synthesized by the preparation method provided by the invention has good stability and high emitted light intensity; during the preparation of the agricultural film, the s-triazine derivative light conversion agent is uniformly distributed in the film, and the agricultural film has a flat and brightsurface and controllable thickness; after the s-triazine derivative light conversion agent is added into EVA resin, a light conversion film can effectively improve the transmitted light quality, and an organically modified light conversion film has relatively good moisture resistance and attenuation resistance; moreover, the mechanical properties of the agricultural film are effectively improved,the service life thereof is prolonged and the application prospect is good.

Description

technical field [0001] The invention relates to an anti-aging blue light conversion agent s-triazine derivative, a preparation method thereof, and an agricultural film prepared, and belongs to the technical field of fluorescent materials or fluorescent marking materials, and agricultural film light conversion materials. Background technique [0002] Agricultural film is an important agricultural production material after seeds, fertilizers, and pesticides. It has the effect of warming up and preserving moisture in the soil. my country is the country with the largest production and use of agricultural film in the world, which is 1.6 times the sum of all other countries. Agricultural film has made an important contribution to increasing agricultural efficiency and increasing farmers' income. With the improvement of crop cultivation technology, agricultural films with various special functions have appeared one after another. Among them, the light-converting agricultural film i...

AI Technical Summary

Problems solved by technology

Among them, inorganic rare earth fluorescent compounds have high fluorescence intensity, but there are problems of sharp peak emission and poor anti-attenuation performance. The world stock of rare earth metal elements is small and the cost is high; although metal-organic complexes have high luminous intensity and good photostability properties, but metal-organic complexes are not conducive to uniform dispersion into polymer resins, resulting in a decrease in the physical and mechanical properties of the film and affecting the light transmittance of the film; organic fluorescent pigments, such as the sulfide-type light-converting agent that has been reported more at present , although the spectral matching is good, but there are defects of deliquescence resistance and poor dispersion in agricultural film
