Abstract
The utility model discloses a combined film with aluminum coating used by large greenhouse, which comprises an internal layer, an external layer and an aluminum coating layer, wherein, bottom surface of the aluminum coating layer is combined with the internal layer and upper surface of the aluminum coating layer is combined with the external layer, that is the aluminum coating layer is arranged between the internal layer and the external layer. When temperature arises too much due to too strong sunlight, effects of shielding the film from sunlight and temperature preservation can be effectively achieved which is favorable with growth of crops and can be applied in extensive scopes.
Description
(1) technical field
The utility model relates to a kind of horticultural covering film, especially a kind of composite greenhouse film of aluminizing.
(2) background technology
The agricultural greenhouse production technology is one of modern agriculture important method of producing, and the horticultural covering film necessary thing that is agricultural greenhouse.The horticultural covering film that can provide all is based on high molecular polymer in the market, adds an amount of function additive, process blow molding processing and preparing.Desirable canopy film material is a polyolefin, as: polyethylene (PE), ethene-vinyl acetate copolymer (EVA) and polyvinyl chloride thermoplastics such as (PVC).Wherein using commonplace horticultural covering film material is polyethylene (PE), and horticultural covering film is all and adds some functional aids again on the basis of blow moulded polyethyene and form.
Common horticultural covering film in use can satisfy the needs of agricultural production substantially, as the patent No. is: 0206247.X, patent name are the utility model patents of Sandwiched heat-insulation qreenhouse film, a kind of thermal insulation greenhouse film is disclosed, be provided with two-layer common canopy film, be provided with air chamber between the common canopy film, heat insulation effect is relatively good; As the patent No. be: 9922421.6, patent name is a heat-insulation and heat-preservation agricultural booth composite membrane, a kind of heat-insulation and heat-preservation booth composite membrane is disclosed, comprise basement membrane, on air-cushion film, be distributed with the air bag of recess shape, basement membrane is tightly connected at the bottom surface and the air-cushion film upper base air bag mouth of air-cushion film, outer membrane is affixed with capsule top end face at the bottom of the air bag at the bottom of the air-cushion film, air-cushion film air layer at the bottom of having formed heat-insulation and heat-preservation between basement membrane and the outer membrane is arranged, effectively the end, prevent that end heat is lost by the canopy film in the booth, and can save trouble at the bottom of canopy film daylighting end face covers straw mat curtain cold-proof heat insulation at night.But also the shortcoming of Cun Zaiing is: because sunlight is too fierce, the summer that environmental temperature is too high, transparent horticultural covering film can't stop between the crops in the canopy and is subjected to being exposed to the sun of sunlight, and if the horticultural covering film of black can absorb a large amount of heat energy the temperature in the canopy is sharply risen, thereby crops are well grown.
(3) summary of the invention
In order to overcome the deficiency that horticultural covering film in the prior art can not be effectively heat insulation when environmental temperature is too high, be kept temperature constant; the utility model provides a kind of novel composite greenhouse film of aluminizing; between internal layer canopy film and outer canopy film, be provided with aluminium coated, when temperature is too high, can effectively play the shading of canopy film and the protective effect that keeps temperature constant.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of composite greenhouse film of aluminizing comprises canopy film inner layer, canopy film skin, also is provided with aluminium coated, and the bottom surface of described aluminium coated and described canopy film inner layer are compound, the top and described canopy film of described aluminium coated outer compound.
Further, described canopy film inner layer is a polyethylene green house film, and described canopy film skin is a polyethylene green house film.
The beneficial effect of the composite greenhouse film of aluminizing described in the utility model mainly shows: 1, be provided with aluminium coated between canopy film inner layer and canopy film skin, the function that has common horticultural covering film fully, and too fierce at sunlight, when environmental temperature is too high, can effectively play the shading of film and the protective effect that keeps temperature constant, help crops and well grow, have extensive applicability; 2, the PE composite greenhouse film is difficult for cut and tears; 3, aluminium coated has higher metallic luster, and internal layer canopy film is that the PE material is made, and can produce shades of colours such as milky, can beautify the farming circle, has excellent decoration.
(4) description of drawings
Fig. 1 is the structure chart of the composite greenhouse film of aluminizing described in the utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of composite greenhouse film of aluminizing comprises canopy film inner layer 1, canopy film skin 2, also be provided with aluminium coated 3, the bottom surface of aluminium coated 3 and canopy film inner layer 1 are compound, and the top and canopy film of aluminium coated 3 outer 2 is compound, and canopy film inner layer 1 and canopy film skin 2 all are that polyethylene (PE) material is made.The composite greenhouse film of aluminizing described in the utility model adopts high strength blowing PE, outer surface at canopy film inner layer 1 is evenly aluminized, composite canopy film skin 2 forms on aluminium coated 3 again, it has all functions of common horticultural covering film, and because be provided with aluminium coated, can play the function of sunshade, lucifuge and the insulation of film when temperature is too high, the PE horticultural covering film of aluminizing has higher metallic luster, can also beautify agricultural garden, have extensive applicability and ornamental.
Claims (2)
1, a kind of composite greenhouse film of aluminizing comprises canopy film inner layer, canopy film skin, it is characterized in that: also be provided with aluminium coated, the bottom surface of described aluminium coated and described canopy film inner layer are compound, the top and described canopy film of described aluminium coated outer compound.
2, the composite greenhouse film of aluminizing as claimed in claim 1 is characterized in that: described canopy film inner layer is a polyethylene green house film, and described canopy film skin is a polyethylene green house film.
