Abstract
The utility model provides a compound heat-preservation quilt for a greenhouse. The compound heat-preservation quilt comprises a waterproof layer (1) and a heat-preservation layer (2), wherein the waterproof layer (1) is a low density polyethylene resin layer; the heat-preservation layer (2) is a net-shaped fiber layer; the waterproof layer (1) is thermally pressed on one surface of the heat-preservation layer (2) by a calendering machine under a certain temperature; the heat-preservation quilt further comprises a heat reflection layer (3); the heat reflection layer (3) is arranged on the other surface of the heat-preservation layer (2) and can prevent heat in the greenhouse from being transmitted out of the greenhouse so as to have the good heat-insulation effect; and a protection layer (4) is compounded outside the heat reflection layer (3) to prevent the heat reflection layer (3) from being abraded and scrapped and has moisture-proof and anti-corrosion effects.
Description
Technical field
The utility model relates to a kind of green house composite thermal-insualting quilt, belongs to the agricultural facility field.
Background technology
Traditional upper insulation material that covers in green house top is mainly straw screen or mat, straw screen or mat is formed with straw is self-editing by farmers', the booth thermal insulation poor performance, easily damaged, be not durable, and raining or the weather that snows, straw screen or mat is understanding that water makes moist and accumulated snow, own wt strengthens at double, and the harm of the booth that collapses easily occurs to press, and has been not suitable for the development of modern agriculture; Composite thermal-insualting quilt consists of by the functional layers such as watertight composition, heat-insulation layer are compound, watertight composition can be made of low-density polyvinyl resin, heat-insulation layer can be made of materials such as spray-bonded nonwaven fabric and expanded materials, the thermal insulation quilt of made has that water resistant is oozed, the advantage such as lightweight, but it is not good still to exist in actual use humidity resistance, the good not deficiency that waits of heat insulation effect.
Summary of the invention
The purpose of this utility model is to provide that a kind of humidity resistance is good, the obvious green house composite thermal-insualting quilt of heat insulation effect.
Realizing by following technical proposals of the utility model purpose:
A kind of green house composite thermal-insualting quilt, comprise watertight composition and heat-insulation layer, described watertight composition is the ldpe resin layer, described heat-insulation layer is arlt's strata, described watertight composition is at a certain temperature on the surface of calender hot pressing at heat-insulation layer, this thermal insulation quilt also comprises heat-reflecting layer, and described heat-reflecting layer is arranged on another surface of heat-insulation layer, and its thickness is 50-100 μ m.
As another kind of improvement the of the present utility model, described heat-reflecting layer is compounded with protective layer outward, and its thickness is 5-20 μ m.
The beneficial effects of the utility model are: 1, thermal insulation quilt has heat-reflecting layer, can reduce the interior heat of booth and transmit outside canopy, plays good insulation effect; 2, the outer compound protective layer of heat-reflecting layer, can prevent that heat-reflecting layer is worn and scratches, and also played the effect of moisture-proof anticorrosive simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, green house composite thermal-insualting quilt of the present utility model, comprise watertight composition 1 and heat-insulation layer 2, described watertight composition 1 is the ldpe resin layer, described heat-insulation layer 2 is arlt's strata, and on the surface of calender hot pressing at heat-insulation layer 2, this thermal insulation quilt also comprises heat-reflecting layer 3 to described watertight composition 1 at a certain temperature, described heat-reflecting layer 3 is arranged on another surface of heat-insulation layer 2, and its thickness is 50-100 μ m.
Described heat-insulation layer 2 is arlt's stratas, and its raw material is comprised of one or more materials such as waste and old rag, terylene, cotton thread, man-made hairs.
As another kind of improvement the of the present utility model, described heat-reflecting layer 3 is outer is compounded with protective layer 4, and its thickness is 5-20 μ m.
Described heat-reflecting layer 3 is a kind of in aluminium foil or tinfoil paper, and this heat-reflecting layer 3 can reduce that in booth, heat transmits outside canopy, play good insulation effect.
Described protective layer 4 is comprised of heat-setting resin, curing agent and thinner, and solidification temperature is 90-110 ℃, and this protective layer 4 can prevent that heat-reflecting layer 3 is worn and scratches, and has also played the effect of moisture-proof anticorrosive simultaneously.
Can realize when complex heat-preservation of the present utility model is used that machinery unreels and rolling, its production technology is simple simultaneously, is fit to streamline production.
Claims (4)
1. green house composite thermal-insualting quilt, comprise watertight composition (1) and heat-insulation layer (2), described watertight composition (1) is the ldpe resin layer, described heat-insulation layer (2) is arlt's strata, described watertight composition (1) hot pressing is on a surface of heat-insulation layer (2), it is characterized in that: this thermal insulation quilt also comprises heat-reflecting layer (3), and described heat-reflecting layer (3) is arranged on another surface of heat-insulation layer (2).
