Abstract

The double-layer greenhouse insulation film of the present invention comprises flat film, capsule film, inlet, outlet, and said flat film is exactly common plastic film; Said capsule film is the plastic film that is processed with tapered point type and semicircle formula capsule. , the capsule is bonded to the flat membrane through the adhesive point of the tapered point capsule and the flat membrane as a whole, and the flat membrane and the capsule are supported by the adhesive point and the bottom of the capsule of the tapered point or semicircular capsule to form a double layer Plastic film; the width of the double-layer greenhouse plastic film of the present invention is 2-12 meters, and the length can be cut according to needs. The present invention adopts water-filled or air-filled heat preservation methods according to actual needs, especially in the cold winter season, when the temperature is low, well water is filled at night and warm water is heated, and air-filled during the day can keep warm without affecting daylighting.

Description

technical field [0001] The invention belongs to the technical field of greenhouse insulation, and in particular relates to a double-layer greenhouse insulation film. Background technique [0002] Most of the existing greenhouse thermal insulation films are single-layer, and the biggest disadvantage of the greenhouse constructed by single-layer plastic film is that the thermal insulation performance is poor, especially in winter. In order to solve this problem, people have adopted many methods. In addition to the traditional method of covering straw curtains for heat preservation, some people have designed and manufactured double-layer plastic films, mainly adding a support frame between the two layers of plastic films. With air, the main disadvantage of this method is that the structure is complicated, the cost is high, the heat preservation and practical effect are not good. Contents of the invention [0003] The purpose of the present invention is to solve the technical...
