[0002] The existing greenhouse farmland insulation layer is made of plastic film covered with straw or wheat straw. Due to the poor heat insulation performance of straw or wheat straw, it affects the temperature control of the farmland, which is not good for the growth of farmland crops in the greenhouse. At the same time, the straw Or the construction cost of wheat straw covering is high and the service life is short; designing a greenhouse thermal insulation film can improve the thermal insulation performance of the greenhouse, reduce construction costs, and increase the service life; to manufacture a greenhouse thermal insulation film requires a greenhouse thermal insulation gas Membrane manufacturing method

Embodiment Construction
[0010] Below according to accompanying drawing and specific embodiment the present invention is further described:
[0011] figure 1 The schematic diagram of the structure of the greenhouse insulation air film shown and figure 2 The schematic diagram of the filling interface structure is shown. The greenhouse insulation air film is composed of air cushion 1 and heat insulation powder 2. The heat insulation powder 2 is distributed in the cavity 3 of the air cushion 1. The air cushion 1 is sealed and connected with the filling interface 4 and the sealing It is connected with an exhaust port 5, and the filling port 4 is provided with an inflatable sealing cover 11, and the exhaust port 5 is provided with an exhaust sealing cover 19, which is used to fill the heat insulation powder 2 into the cavity 3 of the air cushion 1, and the air cushion 1 The cavity 3 is filled with compressed air.
[0012] In order to improve the light transmission performance of the air cushion 1, the a...

A heat insulation air film for a greenhouse consists of an air cushion and heat insulation shreds. The heat insulation shreds are distributed in a cavity of the air cushion so that the air cushion has excellent heat insulation property. The method for manufacturing the heat insulation air film for the greenhouse comprises the steps of: compounding edges of a plastic thin film, manufacturing a shred filling joint, manufacturing an exhausting joint, carrying out compression joint on the shred filling joint, carrying out compression joint on the exhausting joint, hot pressing a locating point, punching a connection hole, manufacturing the heat insulation shreds, filling and packaging the heat insulation shreds, inflating the air cushion, and spraying a heat insulation paint. The heat insulation air film for the greenhouse, manufactured by using a manufacture method provided by the invention, provides a brand new covering material for the greenhouse, and has the advantages of improving the heat insulation performance of the greenhouse, reducing the labor intensity of greenhouse construction and prolonging the service life of the heat insulation layer of the greenhouse.
Description
Technical field [0001] The invention relates to a method for manufacturing a greenhouse heat-insulating air film. Background technique [0002] The existing greenhouse farmland insulation layer is made of plastic film covered with straw or wheat straw. Due to the poor heat insulation performance of straw or wheat straw, it affects the temperature control of the farmland, which is not good for the growth of farmland crops in the greenhouse. At the same time, the straw Or the construction cost of wheat straw covering is high and the service life is short; designing a greenhouse thermal insulation film can improve the thermal insulation performance of the greenhouse, reduce construction costs, and increase the service life; to manufacture a greenhouse thermal insulation film requires a greenhouse thermal insulation gas Membrane manufacturing method. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and p...
