High-performance agricultural greenhouse film and preparation method thereof

Abstract

The invention discloses a high-performance agricultural greenhouse film. The agricultural greenhouse film comprises an anti-oxidation anti-corrosion outer layer, a heat-preservation middle layer and adripping fog-dispersal inner layer, and transparent adhesive agents are used between the anti-oxidation anti-corrosion outer layer and the heat-preservation middle layer and between the heat-preservation middle layer and the dripping fog-dispersal inner layer for adhesion; a preparation method comprises the following steps of preparation of the anti-oxidation anti-corrosion outer layer, preparation of the heat-preservation middle layer, preparation of the dripping fog-dispersal inner layer and adhesion. The invention further provides the preparation method of the high-performance agriculturalgreenhouse film. The high-performance agricultural greenhouse film is very high in dust resistance, corrosion resistance and light transmission, easy to prepare, low in cost, good in popularization value and capable of improving the heat preservation performance of a multilayer structure and fully meeting planting demands.

Description

technical field [0001] The invention relates to the field of film manufacturing, in particular to a high-performance agricultural greenhouse film and a preparation method thereof. Background technique [0002] Agricultural greenhouse film is a special plastic film used for facility agricultural production and construction. It is another important agricultural production increase technology after seeds, fertilizers and pesticides. It is of great significance to the synergy of agriculture and the increase of farmers' production. At present, the most common agricultural greenhouse films in my country mainly include polyethylene and polyvinyl chloride. [0003] Agricultural greenhouse film is a special plastic film used for facility agricultural production and construction. Agricultural greenhouse film is of great significance to the growth, production and income increase of greenhouse crops. The current agricultural greenhouse film usually adopts single-layer polyethylene pla...

AI Technical Summary

Problems solved by technology

The current agricultural greenhouse film usually uses a single-layer polyethylene plastic film. Since the agricultural greenhouse is a single-layer film, the enveloping effect and heat preservation of the agricultural greenhouse film are not very ideal, which is not conducive to crop growth.

In addition, the film with a single-layer structure has low strength, is easy to break, has poor corrosion resistance, and has a short service life. Basically, it needs to be replaced once a year, which invisibly increases the cost of planting.
