Abstract

The invention relates to a thin film and a preparation method thereof, in particular to a light conversion film, a multilayer light conversion film and a preparation method of the multilayer light conversion film. The light conversion film comprises a film body and a light conversion film layer, and the light conversion film layer comprises, by weight, 18%-22% of a light conversion agent, 55%-60%of an organic carrier, 13%-15% of a light stabilizer and 9%-12% of an antioxidant, wherein the film body comprises 60%-75% of a film matrix, 12%-20% of a light stabilizer and 10%-20% of an antioxidant; according to the method provided by the invention, by adding the light conversion agent, ultraviolet light in sunlight can be converted into red light, absorption of plants on nutrient elements suchas nitrogen, phosphorus, potassium and zinc is promoted, the content of photosynthesis products in leaves is increased, crop growth is promoted, and meanwhile, the effect of reducing diseases and insect pests is achieved.

Description

technical field [0001] The invention relates to a thin film and a preparation method thereof, in particular to a light conversion film, a multilayer light conversion film and a preparation method for the multilayer light conversion film. Background technique [0002] Light film is a film that realizes light conversion by adding a light conversion agent. It can convert ultraviolet light that is harmful to plant growth into blue-violet light and red-orange light that are useful to crops, or green light and yellow-green light that plants do not absorb. converted to red light. That is, by changing the light quality that passes through the light conversion film, it can promote the absorption of nitrogen, phosphorus, potassium, zinc and other nutrients by plants, increase the content of photosynthesis products in leaves, promote crop growth, and at the same time play a role in reducing pests and diseases . [0003] At present, the light-converting films used on the market are al...
