Problems solved by technology

[0002] At present, greenhouses are commonly used in agricultural production. The common greenhouses are single-layer plastic films. Although the price is low, the insulation effect is poor, and supplementary heating measures are often needed in the cold winter season.
In addition, the single-layer plastic film can only be used for one plant growth cycle. Generally, it will be damaged within 1-2 months, and the greenhouse often needs to be repaired.

Embodiment Construction

[0009] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0010] The invention relates to a double-layer plastic film for agricultural greenhouses, which includes two outer plastic films, and the two layers of films are connected by a connecting layer of plastic. Interlaced with the two outer films, the folded length of the plastic films connected to the two outer sides is the same, the outer double-layer plastic film and the middle connection film form a triangular prism adjacent to each other, inject water into the triangular prism space formed by each plastic layer, along the above triangular prism The three-layer film is pressed and bonded at regular intervals in the vertical direction of the ribs.

Abstract

The invention discloses a double-layer water injection plastic film. According to the invention, by increasing the layer number, the anti-abrasion capability of the film is enhanced. At the same time, by adopting the water injection design for the middle part of the film, the thermal insulation capability is improved. By adopting the film provided by the invention, the agricultural greenhouse can have a better thermal insulation effect and the service lifetime of the greenhouse plastics can be prolonged.

Description

technical field [0001] The invention relates to a double-layer plastic film, in particular to a double-layer water-injection plastic film for agricultural greenhouses. Background technique [0002] At present, greenhouses are commonly used in agricultural production. The common greenhouses are single-layer plastic films. Although the price is low, the insulation effect is poor, and supplementary heating measures are often needed in the cold winter season. In addition, the single-layer plastic film can only be used for one plant growth cycle. Generally, it will be damaged within 1-2 months, and the greenhouse often needs to be repaired. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and propose a double-layer water-injected plastic film for agricultural greenhouses, so as to achieve the advantages of good heat preservation effect and durability. [0004] In order to achieve the above object, the technical solution ado...
