Abstract
The utility model discloses an agricultural polyolefin changes light canopy membrane, including canopy membrane body, canopy membrane body is by polyolefin raw materials, heat preservation agent, antioxidant and the mixed extrusion of light stabilizer interior tunic, well tunic and outer tunic are just interior tunic, well tunic and outer tunic pass through the shaping of screw extruder blowing unit coextrusion blow, interior tunic internal surface is handled and is coated through the corona mirror surface has fog dispersal drip agent layer. The utility model discloses its drip fog dispersal life -span and canopy membrane life -span itself synchronous and change light effectual, can obtain to satisfy required blue light of agricultural crop growth and orange red bare glistening light of waves ecological environment, solved exist respectively in traditional polyethylene canopy membrane and the use of EVA canopy membrane can't satisfy the required smooth ecological environment of agricultural crop growth and drip fog dispersal nature life -span and EVA canopy membrane life -span non -synchronous problem itself.
Description
Technical field
The utility model relates to agricultural canopy film technical field, is specifically related to a kind ofly turn light canopy film for crops chamber planting.
Background technology
There is light conversion agent and easily drift about, separate out in traditional polyethylene green house film, turn the light effect term of validity short, general only can maintain March about and turn luminous intensity and do not reach requirement, cannot turn light and obtain the orange red light wave that blue light that the wavelength that simultaneously needs of crop growth is 440-480nm and wavelength are 600-680nm, thus traditional polyethylene green house film cannot meet the Photo-ecology environment required for crop growth; Ethene-vinyl acetate copolymer resins canopy film is also EVA canopy film, although have very strong light transmission, its light transmittance reaches 87%, and its drip fog dispersal property life-span is also long, also have good heat insulating ability, dust tightness and ageing-resistant ability, the service life of EVA canopy film itself is also longer simultaneously, but its drip fog dispersal property life-span is asynchronous with the EVA canopy film life-span itself, its drip fog dispersal property life-span is generally in the 4-6 month, and the EVA canopy film life-span itself is 18 months.
Summary of the invention
For the deficiencies in the prior art, the utility model aim to provide a kind of drip fog dispersal life-span synchronous with life-span of canopy film itself and turn good, the high printing opacity of light effect (light transmittance can reach 93%), the agricultural polyolefin of blue light needed for crop growth and orange red light wave Photo-ecology environment can be met turn light canopy film.
For achieving the above object, the utility model adopts following technical scheme:
A kind of agricultural polyolefin turns light canopy film, comprise canopy membrane body, described canopy membrane body mixes extruded by polyolefinic raw materials, heat preserving agent, antioxidant and light stabilizer, comprise inner layer film, mesopelagic layer and outer membrane and described inner layer film, mesopelagic layer and outer membrane are shaping by screw extruder Blown-film line coextrusion blow, described inner layer film inner surface is through corona mirror process and be coated with fog dispersal drip oxidant layer.
The utility model has following beneficial effect:
A kind of agricultural polyolefin of the utility model turns light canopy film, its drip fog dispersal life-span synchronous with life-span of canopy film itself and turn light effect good, can obtain and meet blue light needed for crop growth and orange red light wave Photo-ecology environment, solve cannot meet Photo-ecology environment required for crop growth and the drip that exist respectively in traditional polyethylene green house film and the use procedure of EVA canopy film and to disperse fog property life-span and EVA canopy film life-span nonsynchronous problem itself.
Accompanying drawing explanation
Fig. 1 is the structural texture schematic diagram that a kind of agricultural polyolefin of the utility model turns light canopy film.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the technological thought that the utility model is claimed so that clearer.
A kind of agricultural polyolefin of the utility model turns light canopy film as shown in Figure 1, comprise and mix extruded canopy membrane body 1 by polyolefinic raw materials, heat preserving agent, antioxidant and light stabilizer, described canopy membrane body 1 is shaping by screw extruder Blown-film line coextrusion blow by inner layer film 10, mesopelagic layer 11 and outer membrane 12, and above-mentioned inner layer film 10 inner surface is through corona mirror process and be coated with fog dispersal drip oxidant layer 100.
Operation principle of the present utility model is: it is shaping that inner layer film 10, mesopelagic layer 11 and outer membrane 12 i.e. canopy membrane body 1 adds heat preserving agent, antioxidant and light stabilizer coextrusion blow by polyolefinic raw materials, can ensure to be reflected back to extraradial infrared rays in canopy membrane body 1, effective control heat loss, ensure crops growth temperature at night, shorten the crop maturity phase; In addition, the interpolation of antioxidant and light stabilizer can ensure the service life extending canopy film, and its normal service life can reach 3 years.Therewith, apply fog dispersal drip agent at inner layer film 10 inner surface of canopy membrane body 1 by the mode of corona mirror process simultaneously and form fog dispersal drip oxidant layer 100, canopy membrane body 1 is made to have superpower lasting fog dispersal drip ability, suppress fog to produce, and its fog dispersal drip life-span is consistent for service life with canopy membrane body 1.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
Claims (1)
1. an agricultural polyolefin turns light canopy film, comprise canopy membrane body (1), it is characterized in that: described canopy membrane body (1) mixes extruded by polyolefinic raw materials, heat preserving agent, antioxidant and light stabilizer, comprise inner layer film (10), mesopelagic layer (11) and outer membrane (12) and described inner layer film (10), mesopelagic layer (11) and outer membrane (12) are shaping by screw extruder Blown-film line coextrusion blow, described inner layer film (10) inner surface is through corona mirror process and be coated with fog dispersal drip oxidant layer (100).
