Title:
LIGHT-CONVERSION FILM AND PREPARATION METHOD FOR MULTILAYER LIGHT-CONVERSION FILM
Document Type and Number:
WIPO Patent Application WO/2021/097976
Kind Code:
A1
Abstract:
The present invention relates to a thin film and a preparation method therefor, and specifically relates to a light-conversion film and a preparation method for a multilayer light-conversion film. The light-conversion film comprises a thin film body, a thin film inner layer, and at least one layer and a light conversion film layer provided between the thin film body and the thin film inner layer; the light conversion film layer comprises, in percentage by weight, 18% to 22% of a light conversion agent, 55% to 60% of an organic carrier, 13% to 15% of a light stabilizer and 9% to 12% of an antioxidant; the thin film body comprises 60% to 75% of a thin film base body, 12% to 20% of the light stabilizer, and 10% to 20% of the antioxidant. The method provided by the present invention can convert ultraviolet light in sunlight into red light by adding the light conversion agent, facilitating the absorption of nutritional elements such as nitrogen, phosphorus, potassium and zinc by plants, increasing the content of a photosynthesis product in leaves, promoting the growth of crops, and playing the role of reducing disease and pest damage.
