Abstract
The utility model discloses a composite heat-insulating cover for a plastic-covered greenhouse, which comprises a composite insulating layer and protective layers arranged on two surfaces of the composite insulating layer. The protective layers include an outer protective layer arranged on the outer surface of the composite insulating layer and an inner protective layer arranged on the inner surface of the composite insulating layer; the composite insulating layer comprises a non-woven fabric layer hot-pressed on the inner surface of the outer protective layer; a reticular high expansion polyethylene layer is glued on the inner surface of the non-woven fabric layer; an alumite film is glued on the inner surface of the reticular high expansion polyethylene layer; the non-woven fabric layer is arranged on the inner surface of the alumite film; and the inner protective layer is hot-pressed on the inner surface of the non-woven fabric layer. The utility model has the advantages of good heat-insulating and protection performances, high strength, long service life, light weight, small volume and easy processing.
Description
Technical field
The utility model relates to a kind of greenhouse heat-insulating quilt.
Background technology
Development along with plant husbandry, green house is in crop planting such as vegetables, fruit are cultivated, be widely used, the greenhouse heat-insulating technology is also developed thereupon greatly, and greenhouse heat-insulating quilt has developed into the composite bed thermal insulation quilt that extensively adopts now by initial woven straw thermal insulation quilt.Existing on the market several composite thermal-insualting quilts substantially all have advantages such as good heat insulating, volume in light weight be little, have realized the purpose of greenhouse insulation preferably.But these thermal insulation quilts are when possessing different separately advantages, also there are some defectives, such as: heat-insulation layer adopts the thermal insulation quilt of needle punched felt layer, infiltration easily, freezing easily northerly night in winter forms lump, can produce inconvenience when roll thermal insulation quilt early morning, because the thermal conductivity of water is stronger than heat-insulation layer, therefore, infiltration back heat insulation effect also decreases; The aluminum membranous layer of some composite thermal-insualting quilt directly is compounded in the outermost layer of thermal insulation quilt, shortcoming be aluminum membranous layer easily by frame friction and scuffing repeatedly, cause too early damagedly or come off, influence service life and heat insulation effect; The thermal insulation quilt that has adopts rete to be formed by stacking, and does not prevent the structure of tearing, in use easily by scratches such as limb, the scuffing of crop, and then is colluded from injury region and to pull badly, has influenced service life; Therefore adhesion is not strong between each layer of thermal insulation quilt that has, and adopts suture to sew up or adopt canopy to follow closely to connect each layer, has not only buried the hidden danger of infiltration, must be not easy to process according to actual needs design size in advance during manufacturing, is not easy to cutting yet.More than these defectives all need to eliminate.
The utility model content
Technical problem to be solved in the utility model provides a kind of insulation and barrier propterty is good, intensity is high, long service life, the green house composite thermal-insualting quilt being convenient to process.
For solving the problems of the technologies described above, the technical solution of the utility model is: the green house composite thermal-insualting quilt, comprise outer PE rete, the bottom surface of described outer PE rete is combined with nonwoven layer, be bonded with netted highly foaming polyethylene layer below the described upward nonwoven layer, described netted highly foaming polyethylene layer lower surface is bonded with electrochemical aluminum membranous layer, and the lower surface of described electrochemical aluminum membranous layer is combined with down nonwoven layer, and described nonwoven layer lower surface down is combined with interior PE rete.
Described electrochemical aluminum membranous layer hot pressing or be sprayed on the described down nonwoven layer.
Described outer PE rete is a black flame-retardant PE rete.
The PE rete is fire-retardant PE rete in described.
Described outer PE rete and the described nonwoven layer hot binding that goes up, described interior PE rete and described nonwoven layer hot binding down.
Owing to adopted technique scheme, nonwoven layer had both had heat insulation function, can increase tensile strength again, made this green house composite thermal-insualting quilt tensile strength good, was difficult for by scratch, scratched long service life; Netted highly foaming polyethylene layer strengthens keeping warmth space, has weakened hot conduction, has improved heat insulation effect; The electrification aluminum membranous layer has stopped external thermal radiation in the canopy, further effectively raises heat insulation effect; External protection coating has adopted black flame-retardant PE rete, possesses good rainproof, snow defence, fire-proof function, and black is convenient to the extinction defrosting simultaneously, and frost result of use in season is good; Interior overcoat adopts high-strength anti-flaming PE rete, possesses waterproof, protection against the tide, fireproof effect, and has reduced the wearing and tearing of canopy film, has improved the light transmittance of canopy film, and effectively the inner surface of this thermal insulation quilt of protection is difficult for being scratched simultaneously.The material weight that the utility model adopts is light, intensity is high, also helps miniaturization, the lightness of roller shutter equipment; Make the load of frame little, the body plan of frame can effectively reduce cost, and is more conducive to apply.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, the green house composite thermal-insualting quilt, comprise outer PE rete 1, the bottom surface of outer PE rete 1 is combined with nonwoven layer 2, be bonded with netted highly foaming polyethylene layer 3 below the last nonwoven layer 2, netted highly foaming polyethylene layer 3 lower surface are bonded with electrochemical aluminum membranous layer 4, and the lower surface of electrochemical aluminum membranous layer 4 is combined with down nonwoven layer 5, and following nonwoven layer 5 lower surfaces are combined with interior PE rete 6.Electrification aluminum membranous layer 4 can adopt the method for hot pressing or spraying to combine with following nonwoven layer 5.Outer PE rete 1 is a black flame-retardant PE rete.Interior PE rete 6 is fire-retardant PE rete.Outer PE rete 1 and last nonwoven layer 2 hot bindings, interior PE rete 6 and following nonwoven layer 5 hot bindings.
During preparation, with outer PE rete 1 hot pressing on last nonwoven layer 2, to go up nonwoven layer 2 then is glued on the netted highly foaming polyethylene layer 3, afterwards, with electrochemical aluminum membranous layer 4 hot pressing or be sprayed on down on the nonwoven layer 5, to descend nonwoven layer 5 hot pressing again on interior PE rete 6, outer surface with electrochemical aluminum membranous layer 4 is glued on the netted highly foaming polyethylene layer 3 then, this insulation and barrier propterty are good, intensity is high, long service life, in light weight, volume is little, the green house composite thermal-insualting quilt being convenient to process has just formed.
More than be the application's a embodiment, should be understood that these embodiment only be used to the invention is described and be not used in the restriction the invention scope.Should be understood that in addition those skilled in the art can make various changes or modifications the invention after the content of having read the invention instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
