Abstract
The utility model discloses a compound thermal insulating cover for a greenhouse, and belongs to the field of agricultural facilities. The compound thermal insulating cover for the greenhouse comprises a resin layer (2) and an insulating layer (3), wherein the resin layer (2) is made of low-density polyethylene. The insulating layer (3) is a net-shaped fiber layer. The resin layer (2) is arranged on the surface of the insulating layer (3) in a thermo-compression mode at a certain temperature through a calender. The thermal insulating cover further comprises a hard wearing layer (1), wherein the hard wearing layer (1) is in combination with the outer surface of the resin layer (2) through heat curing. The thickness of the wearing layer is 4-8 micrometer. The compound thermal insulating cover for the greenhouse has the advantages that the rainproof and waterproof functions can be achieved because of the wearing layer, the situation that the thermal insulating cover is scratched and cut can be avoided, and the thermal insulating cover is firm and durable.
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 mainly is 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, it has high insulating effect, the advantage such as lightweight, for realizing supporting the use the condition created with the screen-roller of greenhouse insulation quilt, but behind the normal operation 1-2, the surface waterproofing layer can become fragile, wear out, and is easily damaged, affects serviceability.
Summary of the invention
The purpose of this utility model is to provide a kind of surface ageing-resistant wear-resisting green house composite thermal-insualting quilt.
The following technical proposals of passing through of the utility model purpose realizes:
A kind of green house composite thermal-insualting quilt, comprise resin bed and heat-insulation layer, described resin bed is the ldpe resin layer, described heat-insulation layer is arlt's strata, described resin bed is at a certain temperature on the surface of calender hot pressing at heat-insulation layer, this thermal insulation quilt also comprises wearing layer, and described wearing layer is combined in through heat cure on the outer surface of resin bed, and its thickness is 4-8 μ m.
The beneficial effects of the utility model are: thermal insulation quilt has wearing layer, not only has good rainproof, water-proof function, and can effectively prevent thermal insulation quilt by scratch, scratch, sturdy and durable.
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 resin bed 2 and heat-insulation layer 3, described resin bed 2 is the ldpe resin layer, described heat-insulation layer 3 is arlt's strata, described resin bed 2 at a certain temperature through the calender hot pressing on the surface of heat-insulation layer 3, this thermal insulation quilt also comprises wearing layer 1, described wearing layer 1 is combined on the outer surface of resin bed 2 through heat cure, its thickness is 4-8 μ m, contains the thermal insulation quilt of wearing layer 1, and it not only has good rainproof, water-proof function, and can prevent effectively that thermal insulation quilt is by scratch, scratch, thus the service life of prolongation thermal insulation quilt.
Described wearing layer 1 is comprised of heat-setting resin, curing agent and thinner, and solidification temperature is 90-110 ℃.
Described heat-insulation layer 3 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.
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 (2)
