Problems solved by technology

In recent years, there have been scientific and technological achievements of rare earth light converting agents, which can realize partial conversion in the visible light part, but they have not been applied to the field of agricultural film on a large scale; ultraviolet absorbers are only used in the aging resistance of films

Abstract

The invention discloses an LB light wave optimizing ecological agricultural film for vents and a production technology thereof, which belongs to the field of chemical industry. The LB light wave optimizing ecological agricultural film for the vents is a three-layer coextrusion agricultural film for the vents, wherein, the film is made from Langmuir-Blodgett film (LB), nanometer materials, an ultraviolet absorbent, paint and a light conversion agent by combining an inner adding method. The LB light wave optimizing ecological agricultural film for the vents manufactured according to the method of the invention has cleaner and brighter surface, has the function of optimizing natural light waves, can achieve the effects of long drain and fog dissipation, increases the effect of sterilization and deodorization in the vents, reduces the breeding of pests in the vents, relieves the erosion to the film by pesticide, leads the anti-aging period of the film to be prolonged, decomposes the harmful gases such as pesticide, and the like, in the air of the vents and increases the health of truck farmers, etc.

Description

technical field [0001] The invention relates to an LB light-wave optimized ecological agricultural greenhouse film, which is to produce a three-layer co-extruded agricultural greenhouse film by using an interface molecular film (LB), nanomaterials, ultraviolet absorbers, pigments and light conversion agents in combination with an internal addition method. The invention also relates to a production method of the LB light wave optimized ecological agricultural greenhouse film. It belongs to the field of agricultural science and technology and environment. Background technique [0002] The sun is the light source for the growth of all things. The dripping and defogging function of the agricultural greenhouse film is to allow the sunlight to better illuminate the crops in the greenhouse to increase production. However, each waveband of sunlight has different effects on the growth of crops. Sunlight promotes the growth of all things, and of course all things include harmful orga...
