Description
Technical field
The utility model belongs to agricultural film manufacturing technology field, and in particular to a kind of agricultural photosensitive mutagens color anti-drop defogging
Canopy film.
Background technology
In recent years, China's industrialized agriculture fast development, statistics shows that China's agricultural film consumption in 2015 reaches 2,300,000 tons,
China has become agricultural film largest production state of the world and maximum consumption state.With the development of industrialized agriculture planting technology, to agricultural film
It is also proposed that higher and higher require.By taking canopy film as an example, commonly there is drop film to have drop film antidrip to anti-aging to ageing-resistant from initial
Double anti-films of water propose temperature control, control the requirement of light again now to ageing-resistant, Anti-drip, the three proofings film of fog dispersal.Usually used temperature
Room canopy film is white or light blue, the winter low temperature time, and this film light transmittance is high, contributes to fast lifting temperature of shed, is met
Plant growth needs, but time spring and summer, and temperature is too high, the too strong growth that can suppress crop on the contrary of illumination even causes melon and fruit
Burn, cause the underproduction.
Photosensitive colour-changing material, refer to a kind of specific wavelength excite light irradiation under, with the change of absorption spectrum, material
The absorption characteristic of color either light occur dynamic change, it is a kind of material for occurring color reversible change to be said to.Mesh
Photosensitive colour-changing material is added in plastic sheeting by preceding existing correlative study, such as packaging material, this packaging material can be with illumination
The change of intensity and turn colors, but this photosensitive colour-changing material is applied in agricultural canopy film to there are the following problems：It is photosensitive
Off-color material is a kind of special material, and cost is higher, and greenhouse plastic greenhouse film usage amount is big, and is had necessarily to thickness and intensity
Requirement, directly by photosensitive colour-changing material addition canopy film is made in plastic sheeting matrix material when photosensitive colour-changing material usage amount
Greatly, thus made canopy film cost it is higher, be unfavorable for promoting the use of.
Utility model content
In view of the above-mentioned problems, the utility model is aimed to provide and a kind of the agricultural of turn colors can disappeared with illumination variation without drop
Mist canopy film, and can greatly save the usage amount of photosensitive colour-changing material, reduces cost, using promoting the use of.
A kind of agricultural photosensitive mutagens color anti-drop defogging canopy film, be mainly combined successively from inside to outside by following three-decker and
Into：Drip fog dispersal layer, photosensitive mutagens chromatograph, mechanics layer.

Further, the thickness of drip fog dispersal layer is 1-2 μm, and the thickness of photosensitive mutagens chromatograph is 20-40 μm, mechanics layer
Thickness is 20-60 μm.The thickness of wherein mechanics layer is most thick, is to maintain necessary to product fine mechanical property.Photosensitive mutagens color
The thinner thickness of layer, therefore in the case where meeting photosensitive colour-changing material effectiveness concentration, the utility model photosensitive colour-changing material
Usage amount is few, can greatly save material cost.The thinner thickness of drip fog dispersal layer, therefore in the case where meeting effectiveness concentration,
The utility model drip agent, antifogging agent usage amount it is few, material cost can be greatlyd save.
Further, dispersed fog in drip between layer and photosensitive mutagens chromatograph and also have one layer of mechanics layer, can weakened due to drip
Disperse fog layer and the relatively thin mechanics inferior position brought of photosensitive mutagens chromatograph, makes the overall mechanical properties of product more preferable, and photosensitive mutagens color
The inside and outside of layer is coated with by mechanics layer, is also more conducive to the protection to photosensitive mutagens chromatograph.
Further, there is laminar flow drop fog dispersal layer in the lateral surface of outer layer mechanics layer.So that in canopy film
Outer two sides can play drip performance and fog dispersal performance.
Further, dispersed fog in drip between layer and photosensitive mutagens chromatograph and also have one layer of heat preservation layer, the thickness of the heat-insulation layer
Spend for 20-50 μm, heat-insulation layer can prevent infrared ray to be scattered and disappeared through heat is reduced, using commonly used in the trade outside drip fog dispersal layer
Heat preserving agent and blown film resin material.
Further, there is laminar flow drop fog dispersal layer in the lateral surface of mechanics layer.
It is combined into one structure by conventional method between the sandwich construction of the photosensitive mutagens color anti-drop defogging canopy film, than
As layers of material can be formed between multi-layer co-extruded composite construction, each layer by each extruder and into Multi-layer coextruding die head respectively
Compound Degree firmly, can preferably play the advantage of each layer.
Agricultural photosensitive mutagens color canopy film of the present utility model, is composited by sandwich construction, wherein photosensitive mutagens chromatograph energy
It is changed into the color of setting by white with the increase of intensity of illumination, illumination is stronger, deeper, the opposite intensity of illumination that color becomes
This color can shoal or even change back to again white when dying down, and thus play a part of intensity of illumination and temperature in controllable greenhouse；
Drip fog dispersal layer play capture canopy in steam and be allowed to canopy film inner surface infiltration sprawl into moisture film then along canopy film inner surface from
Ground is arrived in dynamic trickling, reaches Anti-drip, the effect of fog dispersal；Heat-insulation layer has the function that barrier infrared ray is passed through, and night can be effective
Prevent that heat is scattered and disappeared in infra-red radiation mode in greenhouse, plays heat insulation effect；Mechanics layer has excellent tensile strength, puncture resistant
And low-temperature flexibility, strong wind or accidental damage can be resisted.
The utility model provides a kind of new agricultural photosensitive mutagens color anti-drop defogging canopy film, has abandoned in the prior art
Photosensitive colour-changing material and drip agent, antifogging agent are directly added to the method that single layer plastics films are made in matrix material, but
Become one structure using individually making drip fog dispersal layer, photosensitive mutagens chromatograph and mechanics layer respectively and being combined three layers, not only
Disclosure satisfy that mechanical requirements, realization change colour with intensity of illumination, good drip performance and fog dispersal performance, and can greatly reduce
Photosensitive colour-changing material and drip agent, the usage amount of antifogging agent, effectively save cost, beneficial to being widely applied.
