Abstract
隔热保温农用大棚复合膜,它包括有基膜,其特征在于在气垫膜上布有凹窝状的气囊,基膜在气垫膜的底面与气垫膜上的气囊口密封连接,外层膜在气垫膜的上面与气囊的囊顶端面固接。由于基膜与外层膜之间有一层由气垫膜构成的保温的空气层,棚内的热量不能通过棚膜散失,又由于在基膜上增加了气垫膜和外层膜两个复合层使棚膜的强度大大提高、棚膜的使用寿命是传统棚膜的1.5—2倍,可提高棚内温度5—7℃。
The heat-insulation and thermal insulation composite film for agricultural greenhouses includes a base film, which is characterized in that a dimple-shaped air bag is arranged on the air-cushion film, and the base film is sealed and connected with the air-bag opening on the air-cushion film on the bottom surface of the air-cushion film. The upper surface of the air cushion film is affixed to the top surface of the airbag. Because there is an insulating air layer composed of air cushion film between the base film and the outer film, the heat in the shed cannot be lost through the shed film, and because two composite layers of the air cushion film and the outer film are added on the base film. The strength of the shed film is greatly improved, the service life of the shed film is 1.5-2 times that of the traditional shed film, and the temperature in the shed can be increased by 5-7°C.
Description
The utility model relates to a kind of agriculture greenhouse film, more particularly relates to a kind of heat-insulation and heat-preservation agricultural booth composite membrane, belongs to a kind of improvement of agricultural greenhouse awning film.
At present,, make the townsfolk still can be able to eat fresh vegetables, both brought huge economic benefit, enriched townsfolk's life again to the peasant in the winter of severe cold along with popularizing and development of agricultural greenhouse booth.But the current canopy film that uses on the agricultural greenhouse booth adopts the polychloroethylene film of individual layer usually, the heat preservation and insulation of this canopy film is poor, the canopy film that passes through that heat in the canopy is a large amount of scatters and disappears, had a strong impact on the quality and yield of crop, and the canopy film daylighting end face of interim plastic cover greenhouse also will cover last layer and carries out cold-proof heat insulation with the straw mat curtain that the stem or leaf of cattail or straw are compiled into whenever night, so not only strengthened operating cost, but also a large amount of heavy the put curtain and the roller shutter duplications of labour have been increased, the tensile strength of this canopy film is low simultaneously, application life is short, has brought inconvenience to the user.
The purpose of this utility model provides a kind of heat-insulation and heat-preservation agricultural booth composite membrane, and not only heat preservation and insulation is good, tensile strength is high, long service life for it, and the canopy film daylighting end face that can save night at booth covers the trouble that the straw mat curtain is incubated.
The purpose of this utility model is to realize like this, it includes basement membrane, it is characterized in that being furnished with on air-cushion film the air bag of recess shape, basement membrane is tightly connected in the bottom surface of air-cushion film and the air bag mouth on the air-cushion film, and outer membrane is affixed with the capsule top end face of air bag on air-cushion film.
Owing to adopted such scheme, air-cushion film has formed the air layer of heat-insulation and heat-preservation between basement membrane and outer membrane, both guaranteed the booth good light transmittance, prevented that again the heat in the booth scatters and disappears by the canopy film, and also can save the trouble that covers straw mat curtain cold-proof heat insulation at canopy film daylighting end face at night, again owing on basement membrane, increased air-cushion film and two composite beds of outer membrane improve the tensile strength of canopy film greatly.The application life of composite canopy film be traditional canopy film 1-2 doubly, can improve temperature of shed 5-7 ℃ simultaneously, be a kind of novelty and the agricultural booth composite membrane product that shows unique characteristics.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a concrete structure cut-away section schematic diagram of the present utility model.
Fig. 2 is the cross-sectional view of composite membrane.
In Fig. 1-2, distinguish thick 2-4 micron with the basement membrane 6 with good light permeability energy, air-cushion film 5 and outer membrane 2 that igelite is made.On air-cushion film 5, be evenly distributed with the air bag 1 of recess shape, air bag 1 high 3-5mm, air bag 1 is cylindrical.Basement membrane 6 places the bottom surface and affixed being integral of air-cushion film 5 heat pressure adhesives of air-cushion film 5, basement membrane 6 makes rounded sac mouth 4 involutions of the cylindrical air bag 1 on the air-cushion film 5, form the utricule of sealed air-tight, it is fixing that outer membrane 2 places the capsule top end face 3 of the cylindrical air bag 1 on the top and air-cushion film 5 of air-cushion film 5 to stick with glue to connect, outer membrane 2, air-cushion film 5 and basement membrane 6 are fixed as one, at this moment, air-cushion film 5 has constituted the air cushion layer with certain elasticity heat-insulation and heat-preservation between basement membrane 6 and outer membrane 2.
During installation, after the basement membrane 6 of the agricultural booth composite membrane of heat-insulation and heat-preservation being abutted on the skeleton of booth, other all can adopt the peace of common monolayer plastic canopy film to connect method equally to install, on the end limit of composite membrane, basement membrane 6 and outer membrane 2 adhesive seal to be reduced the heat-insulating property that gas flow in the air cushion layer strengthens composite membrane.The utility model through relatively basic more identical with traditional awning film with JD-3 type digital luxmeter, but can improve canopy temperature 5-7 ℃ owing to have the good light transmittance energy.
