Problems solved by technology

But this kind of light conversion function has little application value, because the decay period of the light conversion agent is short (only a few months), and the light conversion intensity is low. With the rapid aging of the film, the light conversion period will end

Abstract

The present invention relates to one kind of sunlight film for covering green house as modern gardening facility and its making process, and belongs to the field of agricultural technology. Low density polyethylene, ethylene-acetic acid copolymer, dripping agent, light stabilizer, composite antioxidant, diluent, light converting agent are mixed to produce concentrated mother material; mother material in 10-15 wt% and base material low density polyethylene or ethylene-acetic acid copolymer in 85-90 wt% are mixed homogeneously; and the mixture is extruded, blown into film and cooled to settle and processed through further steps to produce the sunlight film product. The sunlight film is used to penetrate sunlight, maintain temperature and convert ultraviolet ray into blue and red light essential for plant to perform photosynthesis and is superior to available plastic film for green house in light transparence.

Description

Technical field: [0001] The invention relates to a sunlight film and a manufacturing method thereof, which are used for covering greenhouses in modern facility gardening and belong to the field of agricultural technology. Background technique: [0002] Agricultural greenhouse film is an indispensable and important means of production in modern protected gardening - greenhouse covering material. Its popularization and application have enabled my country to get rid of the era of shortage of agricultural products, making the food and beverages of the people more colorful, and the income of farmers has also increased. In the past 20 years, the manufacturing technology of agricultural greenhouse films has been continuously developed, and the formula has been continuously improved. The first generation of ordinary greenhouse films has developed into the second generation of multifunctional greenhouse films. Its feature is to add specific functional additives to the raw materials,...
