Abstract
The utility model is applicable to the field of film manufacturing and provides a heat-insulation greenhouse film. The heat-insulation greenhouse film comprises at least two layers, vertical ribs used for supporting the film are arranged between the adjacent layers, and the vertical ribs and the film are integrated. A closed heat-insulation air layer is arranged between the adjacent layers, so that the heat-insulation greenhouse film has the advantages of good heat insulation effect, growth of crops in a greenhouse is facilitated, the layers and the vertical ribs are integrally formed, mechanical strength of the greenhouse film is improved, the greenhouse film is not easy to damage, and service life of the greenhouse film is prolonged.
Description
Technical field
The utility model belongs to field of thin film fabrication, relates in particular to a kind of heat preservation greenhouse film.
Background technology
Horticultural covering film is the special plastic film for the industrialized agriculture production and construction, and horticultural covering film is to the growth of greenhouse corps, increases production and increases income significant.The monolayer polyethylene plastic film film that present horticultural covering film adopts usually, because booth is the film of single layer structure, make that the encirclement effect of horticultural covering film is not very desirable, be unfavorable for plant growth, in addition, the film strength of single layer structure is low, cracky, service life is shorter, the heat insulation effect of so just arriving.
The utility model content
In view of the above problems, the utility model provides a kind of heat preservation greenhouse film, is intended to solve the problem that existing horticultural covering film heat insulation effect is not good, intensity is low.
Heat preservation greenhouse film provided by the invention comprises double-layer films at least, is provided with the stud for support film between the described adjacent films, and described stud and described film are one-body molded.
The beneficial effects of the utility model are: the heat preservation greenhouse film that the utility model provides is double-layer films at least, support by stud between the adjacent films, make and have the airtight insulating air layer of one deck between the adjacent films, can improve the heat insulation effect of horticultural covering film so greatly, be conducive to the crop growth in the canopy, one-body molded between each layer film and the stud simultaneously, strengthened the mechanical strength of horticultural covering film, make not cracky of horticultural covering film, prolonged the service life of horticultural covering film.
Description of drawings
Fig. 1 is the width sectional view of the heat preservation greenhouse film that provides of the utility model embodiment;
Fig. 2 is the vertical view of the warm horticultural covering film that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
For technical scheme described in the utility model is described, describe below by specific embodiment.
The heat preservation greenhouse film that present embodiment provides comprises double-layer films at least, is provided with the stud for support film between the described adjacent films, and described stud and described film are one-body molded.Present embodiment does not limit the number of plies of film, the film number of plies is more many, the film spacing is more big, the heat insulation effect of horticultural covering film is more good, but consider the problem of real cost of production and complexity, through experimental verification, preferred, adopt double-layer films also can reach reasonable heat insulation effect, and reduced production cost.
As shown in Figure 1, in the present embodiment preferred version, the heat preservation greenhouse film comprises double-layer films up and down, and described film 1,3 materials up and down are chosen as polyethylene plastic film film usually, and present embodiment is not done concrete restriction.In actual production process, can set the width of film as required, such as 1～3m.
In the present embodiment, thickness between described up and down film can not be too thick can not be too thin, if the too thick mechanical property that then influences horticultural covering film of film spacing, if the too thin heat insulation effect that then has influence on horticultural covering film of film spacing, through overtesting, described in this enforcement up and down the thickness between film be preferably 0.5～2.0mm.The spacing of same described stud 3 can not be too wide or too narrow, if stud 3 spacings are too wide, then possibly can't support film up and down, have influence on the mechanical property of horticultural covering film, if the stud spacing is too narrow, then can improve the production difficulty of horticultural covering film, also can increase the production cost of horticultural covering film simultaneously, therefore through overtesting, the spacing of stud described in this enforcement is preferably 2～10mm.
Be further used as preferred embodiment a kind ofly, as shown in Figure 2, use the heat-sealing machine pressing together perpendicular to the heat seal impression 4 of described stud 3 at a certain distance at the length direction of described film.Of particular note, the heat preservation greenhouse film that present embodiment provides need not to inflate interface, in the horticultural covering film production process, owing to have air between the film, impress heat seal impression 4 one with heat-sealing machine at a certain distance at the horticultural covering film length direction, air just is sealed in the confined space that film, stud and heat seal impression are formed up and down automatically like this, therefore need not to inflate separately to horticultural covering film, simplified production procedure, reduced production cost, make that the practicality of the horticultural covering film that utility model provides is better, can in agricultural production, extensively promote.As a kind of attainable mode, the spacing of described heat seal impression 4 is 500～2000mm.
To sum up, present embodiment provides a kind of heat preservation greenhouse film, comprise double-layer films at least and the stud that is used for support film, formed the air layer of one deck for insulation between the film, make the better heat preservation of horticultural covering film, further, as preferred embodiment a kind of, length direction at film carries out pressing with heat-sealing machine at a certain distance, make air between the film be sealed in automatically one by one in the confined space, the process that need not to inflate has separately reduced the production cost of horticultural covering film, and practical function is higher.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
