Problems solved by technology

PO membrane also has excellent dripping performance. Studies have shown that the dripping duration of PO membranes can even be synchronized with the life of the membrane, while the dripping duration of ordinary membranes is generally only 3 to 4 months.
In addition, ordinary films either do not have the ability to eliminate fog, or the ability to eliminate fog is very limited (only 4 to 6 months)

Abstract

The invention relates to the technical field of agricultural films, in particular to a polyolefin film with a layered structure and application thereof. The polyolefin film comprises a silica sol coating, an outer layer film, a middle layer film, a secondary inner layer film and an inner layer film. The surface of the outer layer film is coated with the silica sol coating, so that the surface of the outer layer film can be endowed with an excellent fog dispersal and dripping function, the fog dispersal and dripping period and the service life of the PO film prepared through the method can reach 5.5 years or above, and the fog dispersal and dripping period and the service life of the PO film are remarkably prolonged. Meanwhile, most far infrared rays radiated outwards in a greenhouse can be reflected back by utilizing the special structure and composition of hydrotalcite, so that a heat preservation effect is achieved, the test shows that the temperature in the greenhouse at night is 2-5 DEG C higher than that of a common greenhouse, the yield and income of crops are increased, the quality of the crops is improved, and the crops are promoted to appear on the market early.

Description

technical field [0001] The invention relates to the technical field of agricultural films, in particular to layered polyolefin films and applications thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Agricultural film is an important agricultural production material after seeds, chemical fertilizers, and pesticides. The application of various high-function agricultural films has made great contributions to agricultural innovation and efficiency, and farmers’ increase in production and income, such as shed film, mulch film, and green storage film. Plastic film is an indispensable material for the development of modern facility agriculture. [0004] PO, or polyolefi...
